Answers

Answer 1

Answer:

See explanation!

Step-by-step explanation:

Let us first give some principle theory to aid our solution.

Considering two functions [tex]A(x)[/tex] and [tex]B(x)[/tex], in order to show that function

which is the inverse of [tex]y=ax[/tex].

Now let as solve our problem. We are given the following:

[tex]f(x)=3x-4\\g(x)=\frac{x+4}{3}[/tex]

Method A: Show that these are inverse functions by finding f^-1 (x) and showing that it is the same as g(x).

Let us take [tex][f(x)=y]=3x-4[/tex] and "exchanging" our variables we have

[tex]x=3y-4\\x+4=3y\\\\y=\frac{x+4}{3}[/tex]

which is exactly the same with our given function of [tex]g(x)=\frac{x+4}{3}[/tex], so proved!

Method B: Show that these are inverse functions by showing that when the output of one function is used for the input of the other function, the final output is equal to the original input value. (you may choose any initial input)

For this case we will use a simple input let us say [tex]x=1[/tex]. Thus taking the [tex]f(x)[/tex] function and plugging in we have:

[tex]f(x=1) = 3(1)-4\\f(1)=3-4\\f(1)=-1[/tex]

Now let us take the output of [tex]f(1)[/tex] which is [tex]-1[/tex] and use it the input to our second function of [tex]g(x)[/tex], so we have:

[tex]g(x=-1) = \frac{(-1)+4}{3}\\ \\g(-1)=\frac{3}{3}\\ \\g(-1)=1[/tex]

so the output of the second function is equal to the original input value of the first function, hence proved!

Method C: Verify that these are the inverse function by showing that f(g(x)) = x AND g(f(x)) = x.

Basically we are asked to prove that both [tex]f(g(x))=g(f(x))=x[/tex]

To do so, we just replace one function into the [tex]x[/tex] value of the other function as follow:

[tex]f(g(x))=3(\frac{x+4}{3} )-4\\\\f(g(x))=x+4-4\\\\f(g(x))=x[/tex]

Lets repeat now for the opposite as follow:

[tex]g(f(x))=\frac{(3x-4)+4}{3}\\ \\g(f(x))=\frac{3x}{3}\\ \\g(f(x))=x[/tex]

Hence proved!

Which expression is equivalent to the one in the picture?

Answers

Answer:

d.

Step-by-step explanation:

To convert a root to a fraction in the exponent, remember this rule:

[tex]\sqrt[n]{a^{m}}=a^{\frac{m}{n}}[/tex]

The index becomes the denominator in the fraction. (The index is the little number in front of the root, "n".) The original exponent remains in the numerator.

In this question, the index is 4.

The index is applied to every base in the equation under the root. The bases are 16, 'x' and 'y'.

[tex]\sqrt[4]{16x^{15}y^{17}} = (\sqrt[4]{16})(\sqrt[4]{x^{15}})(\sqrt[4]{y^{17}}) = (2)(x^{\frac{15}{4}}})(y^{\frac{17}{4}}) = 2x^{\frac{15}{4}}}y^{\frac{17}{4}}[/tex]

To find the quad root of 16, input this into your calculator. Since 2⁴ = 16, [tex]\sqrt[4]{16}[/tex] = 2.

For the "x" and "y" bases, use the rule for converting roots to exponent fractions. The index, 4, becomes the denominator in each fraction.

[tex]2x^{\frac{15}{4}}y^{\frac{17}{4}}[/tex]

For his coffee shop, Abdul wants to make a mocha-java blend that will sell for $18/kg. The mocha coffee beans sell for $20/kg, and the java coffee beans sell for $15/kg. How many kilograms of each kind of coffee bean should he use to make 50 kg of the mocha-java blend?

Answers

Answer:

Step-by-step explanation:

let

x = kg of mocha beans

y = kg of java beans

so

(1)   x + y = 50

(2)   20x + 15y = 18(50)

What is the answer to this equation. -g+2(3+g)=-4(g+1)

Answers

Answer:

The answer to the given equation -g+2(3+g)=-4(g+1) is g=-2

Step-by-step explanation:

Given -g+2(3+g)=-4(g+1)

To solve the given equation :

-g+2(3+g)=-4(g+1)

Applying the distributive property we get

-g+2(3)+2(g)=-4(g)+(-4)(1)

-g+6+2g=-4g-4

g+6=-4g-4 ( adding the like terms )

g+6-(-4g-4)=-4g-4-(-4g-4)

Applying the distributive property we get

g+6-(-4g)-(-4)=-4g-4-(-4g)-(-4)

g+6+4g+4=-4g-4+4g+4

5g+10=0 ( adding the like terms )

5g+10-10=0-10

5g=-10 ( adding the like terms )

[tex]g=-\frac{10}{5}[/tex]

[tex]g=-2[/tex]

Therefore g=-2

The answer to the given equation -g+2(3+g)=-4(g+1) is g=-2

Ethan needs to save at least $500 to purchase a new dirt bike. So far, he has saved $175. If he hopes to use two-fifths of his next paycheck to cover the remaining amount, how much money must he make in his paycheck

Answers

Answer:

$812.5

Step-by-step explanation:

Given: Ethan need to save at least $500.

          He has saved so far $175

          Ethan hope to use two-fifths of his next paycheck to cover the remaining amount.

Lets assume Ethan´s paycheck amount be "x"

First finding the remaining amount to be covered.

Remaining amount= [tex]\$ 500 - \$ 175= \$ 325[/tex]

The remaining amount to be covered is $325.

As given, Ethan hope to use two-fifths of his next paycheck to cover the remaining amount.

Now, using the inequality to find the amount of paycheck.

⇒ [tex]x\times \frac{2}{5} \geq \$ 325[/tex]

multiplying both side by 5

⇒ [tex]x\times 2\geq 325\times 5[/tex]

divinding both side 2

⇒ [tex]x\geq \frac{1625}{2}[/tex]

∴ [tex]x\geq \$ 812.5[/tex]

Hence, Ethan must make at least $812.5 in his paycheck to cover his remaining anount to buy dirt bike.

Answers

The value of the 5 in 50.8 is 1,000 times the value of the 5 in 18.35 1st answer

Step-by-step explanation:

Let us revise some important notes in a number:

Every digit in a number has a place valuePlace value is the value represented by a digit in a numberEx: the place value of 2 in the number 2,345 is 1,000 because 2 is in the thousands place, the place value of 9 in 12.29 is 0.01 because 9 is in the hundredths place

∵ The number is 50.8

∵ 5 is in the tens place

∴ The place value of 5 is 10

∵ The number is 18.35

∵ 5 is in the hundredths place

∴ The place value of 5 is 0.01

Let us compare between the places value of 5 in the two numbers

Let x the number which multiplying by the hundredth digit to give the ten digit

∵ 10 = x × 0.01

∴ 10 = 0.01 x

- Divide both sides by 0.01

1,000 = x

∵ 5 × 10 = 0.05 × 1000

∴ 50 = 50

∴ The value of 5 in 50.8 = 1,000 × the value of 5 in 18.35

The value of the 5 in 50.8 is 1,000 times the value of the 5 in 18.35

In the given relation (-2,4), (1,3), (0,-4), (3,2), the domain comprises the first elements of each pair, which are -2, 1, 0, and 3. Therefore, the domain of this relation is the set {-2, 1, 0, 3}.

true or false:the points (6,13),(21,33),(99,137)all lie on the-same line. the equation of the line is y=4/3x +5

Answers

The answer is true.

Step-by-step explanation:

To find the points all lie on the same line, we need to substitute the points in the equation of the line, to determine if the values on both sides of the equation are equal.

Substituting the point [tex](6,13)[/tex] in the equation of the line, we get,

[tex]\begin{aligned}y &=\frac{4}{3} x+5 \\13 &=\frac{4}{3}(6)+5 \\&=4(2)+5 \\&=8+5 \\13 &=13\end{aligned}[/tex]

Thus, the values on both sides are equal. The point [tex](6,13)[/tex] lie on the same line.

Substituting the point [tex](21,33)[/tex] in the equation of the line, we get,

[tex]\begin{aligned}y &=\frac{4}{3} x+5 \\33 &=\frac{4}{3}(21)+5 \\&=4(7)+5 \\&=28+5 \\33 &=33\end{aligned}[/tex]

Thus, the values on both sides are equal. The point [tex](21,33)[/tex] lie on the same line.

Substituting the point [tex](99,137)[/tex] in the equation of the line, we get,

[tex]\begin{aligned}y &=\frac{4}{3} x+5 \\137 &=\frac{4}{3}(99)+5 \\&=4(33)+5 \\&=132+5 \\137 &=137\end{aligned}[/tex]

Thus, the values on both sides are equal. The point [tex](99,137)[/tex] lie on the same line.

Thus, all the three points lie on the same plane.

Hence, the answer is true.

All three points (6 , 13), (21 , 33), and (99 , 137) lie on the line y = [tex]\frac{4}{3}[/tex]x + 5. Thus, the statement is True, all three points make the equation true. Option 3 is the correct answer.

To determine whether the points (6,13), (21,33), and (99,137) all lie on the line y = [tex]\frac{4}{3}[/tex]x + 5, we need to substitute the x-values of each point into the equation and see if the corresponding y-values match.

1. For the point (6,13):

Substitute x = 6 into the equation.

⇒ y = ([tex]\frac{4}{3}[/tex]) × 6 + 5

⇒ y = 8 + 5

⇒ y = 13

Since the y-value matches, the point (6,13) is on the line.

2. For the point (21,33):

Substitute x = 21 into the equation.

⇒ y = ([tex]\frac{4}{3}[/tex]) × 21 + 5

⇒ y = 28 + 5

⇒ y = 33

Since the y-value matches, the point (21,33) is on the line.

3. For the point (99,137):

Substitute x = 99 into the equation.

⇒ y = ([tex]\frac{4}{3}[/tex]) × 99 + 5

⇒ y = 132 + 5

⇒ y = 137

Since the y-value matches, the point (99,137) is on the line.

All three points satisfy the equation y = [tex]\frac{4}{3}[/tex]x + 5. Therefore, the statement is True: all three points make the equation true option (3).

Complete question:

True or False:

The points (6,13), (21,33) and (99,137) all lie on the same line. The equation of the line is y = [tex]\frac{4}{3}[/tex]x + 5.

Select the correct explanation.

False, all three points do not make the equation true.True, all three points are positive.True, all three points make the equation true.False, all three points are positive.

Therefore [tex]\frac{4(2x^3y^4)^4}{2(2x^2y^6)^3}=\frac{4x^6}{y^2}[/tex]

Step-by-step explanation:

Given fractional expression is [tex]\frac{4(2x^3y^4)^4}{2(2x^2y^6)^3}[/tex]

To simplify the given expression as below :

[tex]\frac{4(2x^3y^4)^4}{2(2x^2y^6)^3}[/tex]

[tex]=\frac{2(2x^3y^4)^4}{(2x^2y^6)^3}[/tex]

[tex]=\frac{2[(2)^4(x^{12})(y^{16})]}{(2)^3(x^6)(y^{18})}[/tex]

[tex]=2[(2)^4(x^{12})(y^{16})](2)^{-3}(x^{-6})(y^{-18})[/tex]  (  ( using the property [tex]a^m=\frac{1}{a^{-m}}[/tex] )

[tex]=2[2^{4-3}x^{12-6}y^{16-18}][/tex]( using the property [tex]a^m.a^n=a^{m+n}[/tex] )

[tex]=2[2^1x^6y^{-2}][/tex]

[tex]=\frac{4x^6}{y^2}[/tex] ( using the property [tex]a^m=\frac{1}{a^{-m}}[/tex] )

Therefore the simplified expression is [tex]\frac{4x^6}{y^2}[/tex]

Therefore [tex]\frac{4(2x^3y^4)^4}{2(2x^2y^6)^3}=\frac{4x^6}{y^2}[/tex]

x + x + 1 = 105

Combine the like terms

2x + 1 = 105

2x = 105 - 1

2x = 104

Divide both sides of equation by 2

x = 52

Answers

There are 11,375 ounces are still in the bucket ⇒ (not in the choices)

Step-by-step explanation:

An art teacher is cleaning up her room at the end of the week

She combines three jars containing 212 ounces, 825 ounces, and 11110 ounces of blue paint in an empty bucketThis bucket is then used to fill one can with 414 ounces of the paint and another can with 358 ounces of the paint

We need to find how many ounces of blue paint are still in the bucket

∵ The jars have 212 ounces, 825 ounces, and 11110 ounces of blue paint

∵ She combines all of them in an empty bucket

- Add them to find the quantity of the blue paint in the bucket

∴ The bucket contains = 212 + 825 + 11110

∴ The bucket contains = 12,147 ounces

∵ This bucket is then used to fill one can with 414 ounces of

   the paint and another can with 358 ounces

- Add them to find the quantity that used from the bucket

∵ She used = 414 + 358 = 772

∴ 772 ounces is used to fill the two cans

To find how many ounces of the blue paint are still in the bucket subtract from the total amount of paint in the bucked the amount used to fill the two cans

∵ The remainder paint in the bucket = 12,147 - 772

∴ The remainder paint in the bucket = 11,375 ounces

There are 11,375 ounces are still in the bucket

Sharon serves the volleyball with an upward velocity of 23 ft/s. The ball is 3.5 ft above the ground when struck. How long does Barbara have before the ball hits the ground?

Answers

We can use the kinematic equation:

h = vi*t + 0.5*a*t^2

where h is the initial height, vi is the initial velocity, a is the acceleration due to gravity (9.8 m/s^2 or 32 ft/s^2), and t is the time.

Since we want to find the time it takes for the ball to hit the ground, we can set h = 0 and solve for t:

0 = 23*t - 0.5*32*t^2 + 3.5

0 = -16t^2 + 23t + 3.5

Using the quadratic formula, we get:

t = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = -16, b = 23, and c = 3.5.

t = (-23 ± sqrt(23^2 - 4*(-16)*3.5)) / 2*(-16)

t = (-23 ± sqrt(529)) / (-32)

t = (-23 ± 23) / (-32)

t = 0.125 s or 1.438 s

Since we are looking for the time it takes for the ball to hit the ground, we only want the positive solution:

t = 1.438 s

Therefore, Barbara has about 1.438 seconds before the ball hits the ground.

Final answer:

Barbara has approximately 1.43 seconds before the volleyball served by Sharon with an upward velocity of 23 ft/s and from a height of 3.5 ft hits the ground.

Explanation:

To determine how long Barbara has before the volleyball hits the ground, we need to use the kinematic equations for projectile motion, assuming the ball is moving under the influence of gravity alone. Since Sharon serves the volleyball with an upward velocity of 23 ft/s and the initial height is 3.5 ft, we can use the following kinematic equation:

[tex]s = ut + (1/2)at^2[/tex]

Where:

s is the displacement (which is -3.5 ft because the ball is falling to the ground, hence the negative sign)

u is the initial velocity (23 ft/s upwards, hence positive)

a is the acceleration due to gravity ( [tex]-32 ft/s^2[/tex], negative because it is directed downward)

t is the time

Plugging in the values we get:

[tex]-3.5 = 23t - (1/2)(32)t^2[/tex]

This is a quadratic equation in the form of  [tex]at^2 + bt + c = 0[/tex] , where a = -16, b = 23, and c = -3.5. We can solve for t using the quadratic formula [tex]t = \frac{{-b \pm \sqrt{{b^2 - 4ac}}}}{{2a}}[/tex]. After calculating, we find that t is approximately 1.43 seconds. However, since time cannot be negative, we take the positive value which is the time it takes for the ball to hit the ground.

Therefore, Barbara has approximately 1.46 seconds before the volleyball hits the ground.

Hakeem shot the basketball 28 times and made 17 baskets. What percent of his shots were baskets?

Answers

Answer:

60%

Step-by-step explanation:

Final answer:

To find the percentage of successful basketball shots, divide the number of made shots by the total number shots taken, then multiply by 100. In Hakeem's case, his shooting percentage is approximately 61%.

Explanation:

This is a question about calculating a percentage, which is a basic concept in Mathematics. Percentages are a way of expressing a number or proportion as a fraction of 100. In this case, Hakeem made 17 out of 28 basketball shots. This can be expressed as a fraction – 17/28. To convert this fraction into a percentage, you simply multiply it by 100.

Here is the calculation: (17 / 28) * 100 = 60.71. Therefore, Hakeem made approximately 61% of his basketball shots.

What is the solution to the equation? 13 and three-fourths + x = 7 and one-fourth

Answers

The solution of the expression of 13 and three-fourths + x = 7 and one-fourth equation is x = [tex]6\frac{1}{2}[/tex]

To solve this equation, we need to find the value of x (unknown variable) in the given equation:

13 and three-fourths + x = 7 and one-fourth

First, we need to convert the mixed numbers to improper fractions.

13 and three-fourths = [tex]13 + \frac{3}{4} = 13\frac{3}{4}[/tex]

7 and one-fourth = [tex]7 + \frac{1}{4} = 7 \frac{1}{4}[/tex]

Now, the equation becomes:

[tex]13\frac{3}{4} + x =7\frac{1}{4}\\ x = 13\frac{3}{4} - 7\frac{1}{4}\\\\x = 6\frac{1}{2}[/tex]

Determine whether the equation has no solution, one solution, or infinitely many solutions. 7(12 2 x ) = 4(3 3 x ) Given a double variable named x that has been declared and given a value, let's use a binary search technique to assign an estimate of its square root to another double variable, root that has also been declared. Let's assume that x's value is greater than 1.0 -- that will simplify things a bit. Here's the general idea:Since x>1, we know its square root must be between 1 and x itself. So declare two other variables of type double (a and b say) and initialize them to 1 and x respectively. So we know the square root must be between a and b. Our strategy is to change a and b and make them closer and closer to each other but alway make sure that the root we're looking for is between them. (Such a condition that must always hold is called an invariant.)To do this we will have a loop that at each step finds the midpoint of a and b. It then squares this midpoint value and if the square of the midpoint is less than x we know that the root of x must be bigger than this midpoint: so we assign the midpoint to a (making a bigger and shrinking our a and b interval by half!)-- and we still can be sure that the root is between a and b. Of course if the midpoint's square is greater than x we do the opposite: we assign b the value of midpoint.But when to stop the loop? In this exercise, just stop when the interval between a and b is less than 0.00001 and assign root the midpoint of a and b then.We call this a binary search also because at each stage we cut the interval under consideration in half. Efficient as this method is, old Isaac Newton discovered an algorithm that is even more efficient and that's what the library function sqrt uses.I have this:double a=1, b=x;double mid;while(a-b>0.00001){mid=(a+b)/2;mid=mid*mid;if (mida=mid;else if(mid>x)b=mid;elseroot=mid;} when evaluating word choice it is important to Ruby Corporation, a calendar year, accrual method C corporation, has two cash method, calendar year shareholders who are unrelated to each other.
