Step-by-step explanation:

bc IM JUICE WRLD

Answer:

See attachment.

Step-by-step explanation:

The equation of the function is

[tex]y=-4x+7[/tex]

The slope of this function is

[tex]m=-4[/tex] and the y-intercept is [tex]c=7[/tex].

This implies that the graph of the straight line passes through (0,7).

Let us also find the x-intercept by putting y=0 into the equation.

[tex]0=-4x+7[/tex]

[tex]-7=-4x[/tex]

Divide through by -4.

[tex]\Rightarrow x=\frac{7}{4}[/tex]

Therefore the graph also passes through [tex](\frac{7}{4},0)[/tex].

We plot these two points and draw a straight line through them.

Answer: Last option.

Step-by-step explanation:

The formula for calculate the area of the circle is the shown below:

[tex]A_c=r^2\pi[/tex]

Where r is the radius of the circle.

As you can see in the figure attached, the radius of the circle is 6 units, then:

[tex]r=6units[/tex]

Therefore, when you substitute the value of the radius into the formula shown above, you obtain the following result:

[tex]A_c=(6\ units)^2\pi[/tex]

[tex]A_c=36\pi\ units^2[/tex]

Answer:

The correct answer is 36π square units

Step-by-step explanation:

Points to remember

Area of circle = πr²

Where r - radius of circle

From the figure we can see a circle with radius 5 units

To find the area of circle

Area = πr² = π * 6² = 36π  square units

Area of given circle = 36π  square units

Therefore the correct answer is 36π  square units

Step-by-step explanation:

The given inequality is [tex]-3\:<\:x\:<\:14[/tex].

The boundaries of the inequality are not inclusive.

We use the "()" to indicate that the interval is open.

The required interval notation is [tex](-3,14).[/tex]

Answer: option a.

Step-by-step explanation:

 By definition we know that:

 [tex]log_a(a^n)=n[/tex]

Where a is the base of the logarithm.

 We also know that:

[tex]\sqrt{x}=x^{\frac{1}{2}}[/tex]

Then you can rewrite the logarithm given in the problem, as you can see below:

[tex]log_{17}(\sqrt{17})[/tex]

And keeping on mind the property, you obtain:

[tex]=log_{17}(17^{\frac{1}{2}})=\frac{1}{2}[/tex]

Therefore, you can conclude that the answer is the option a.

Answer:

The answer is 1/2 ⇒ answer (a)

Step-by-step explanation:

*The logarithm function is the inverse of the exponential function

- Ex: If 2³ = 8 ⇒  then [tex]log_{2}(8) = 3[/tex]

 Vice versa : If [tex]log_{5}(125)=3[/tex] ⇒ 5³ = 125

* In logarithm function:

- If [tex]log_{a}a=1[/tex] because [tex]a^{1}=a[/tex]

- If [tex]log_{a}a^{n}=(n)log_{a}a=n[/tex]

∵ [tex]log_{17}\sqrt{17}=log_{17}(17)^{\frac{1}{2}}[/tex]

- √b = [tex]b^{\frac{1}{2}}[/tex]

∴ [tex]log_{17}(17)^{\frac{1}{2}}=\frac{1}{2}log _{17}(17)=\frac{1}{2}(1) = \frac{1}{2}[/tex]

∴ The answer is 1/2 ⇒ answer (a)

Answer:

47°

Step-by-step explanation:

so a straight line is 180°

It gives us 82° for line D, so to find angle C, we must do 180° - 82° = 98 °

Hopefully you know that a triangle is also 180°

we know two angles: 35, 98

35° + 98° = 133°

180°-133°= 47°

47° is angle B

Answer:

m<B = 47°

Step-by-step explanation:

<ACD is a straight angle and this angle is exactly 180 degrees

As you know

<ACB + <BCD = <ACD

<ACB + 82 = 180

<ACB = 180 - 82

<ACB = 98°

Sum of interior angles in a triangle = 180°

So

<A + <B + <ACB = 180°

35° +<B + 98° = 180°

<B + 133° = 180°

<B = 180° - 133°

<B = 47°

Answer:

  a = -3/2

Step-by-step explanation:

You can set x=0 and solve for y to find the y-intercept in each case.

  first equation: y-intercept = -3/2

  second equation: y-intercept = a

To make these equal, we must have ...

  a = -3/2

Doubling the number every night will result in 4,194,304. How can that girl possibly sleep now with all those magic pennies?

Answer: The girl will have $524.288 (524,288 pennies) after 19 nights.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

So, we have to write an exponential expression where the initial value (a) is 1, the multiplicative rate of growth (b) is 2, and the time period (x) is 19.

Mathematically speaking: (where "y” is the total money)

y = ab×

y = 1 x (2) ∧19 = 524,288 pennies

Since 1 dollar = 100 pennies,

524,288 / 100 = $524.288

The girl will have $524.288 (524,288 pennies) after 19 nights.

Answer:

10(32 - n)

Step-by-step explanation:

This is a beginning algebra question. It is trying to find out if you know what a difference is.

A difference always means subtract in math. Always. There are no exceptions.

So the difference between 32 and n is 32 - n

This difference is multiplied by 10

10(32 - n)

Usually the number mentioned first is the number put to the left of the subtract sign.

If you tell me the answer is 10(n - 32) then you should say that it is the difference between n and 32.

To simplify the expression given in the problem, you must apply the proccedure shown below:

1- According the Exponents Rules, you know the following:

[tex]a^0=1\\\\a^{-n}=\frac{1}{a^n}[/tex]

2- Therefore, keeping the above on mind, you can simplify the expression given in the problem as you can see below:

[tex]x^0yz^{-3}=(1)yz^{-3}\\\\=yz^{-3}\\\\=y\frac{1}{z^3}\\\\=\frac{y}{z^3}[/tex]

To start off scaling is another way of saying resizing the numbers --

Example: "1" on paper means "10" in real life   --

To predict a product of a number/fraction using scaling, you would compare the size of a product on the basis of the size of the other.

Most scaling is used in maps or something to do with rulers

Just did in edg

Answer:

1. By substitution property of inequality

5(9.5)+4.5[tex]\leq[/tex]65

2. By using multiplication  in equality then we get

47.5+4.5x[tex]\leq[/tex]65

3. The five friends will have 3 snacks to split.

Step-by-step explanation:

Given

Five friends have total money= $65

Cost of each movie ticket= $9.50

Cost of each snack item= $4.50

Let ,five friends have total snacks = x

Total movie tickets=5

Because total number of friends=5

The inequality expressionis given by

I Step: [tex]5(9.5)+4.5x\leq 65[/tex]

Reason: By using substitution property of inequality

[tex]47.5+4.5x\leq 65[/tex

2. Step :[tex]4.5x[tex]\leq[/tex]65-47.5[/tex]

[tex]4.5x\leq 17.5[/tex]  ( by subtarction 47.5  from both sides)

[tex]x\leq \frac{17.5}{4.5}[/tex]   ( by dividing 4.5 on both sides )

Because they can buy maximum 3 snacks .

Beacause the number of snacks is natural number so we can't take in rational numbers.

Let

x----> the length of the cut (hypotenuse of a right triangle)

[tex]x^{2}=L^{2} +W^{2}[/tex]

substitute the given values

[tex]x^{2}=15^{2} +8^{2} \\ \\x^{2}= 289\\ \\x=17\ ft[/tex]

To find the length of the diagonal cut on the rectangular board, use the Pythagorean Theorem by square rooting the sum of the squares of the length and width. In this case, the cut will be 17 feet long.

To find the length of the cut:

Answer:

D. [tex]y=\frac{7}{2}x[/tex]

Step-by-step explanation:

We are asked to find the equation, which represents the direct variation that contains the ordered pair (2,7).

When two quantities are proportional to each other, they are in form [tex]y=kx[/tex], where, k represents constant of variation.

Upon substituting [tex]y=7[/tex] and [tex]x=2[/tex] in above equation, we will get:

[tex]7=k\cdot 2[/tex]

Let us solve for k by dividing both sides by 2:

[tex]\frac{7}{2}=\frac{k\cdot 2}{2}[/tex]

[tex]\frac{7}{2}=k[/tex]

Therefore, our required equation would be [tex]y=\frac{7}{2}x[/tex] and option D is the correct choice.

In your case,

[tex]\lim_{x \to 4} h(x)=-2\neq 0,[/tex]

then

[tex]\lim_{x\to 4}\dfrac{g(x)}{h(x)}=\dfrac{ \lim_{x \to 4} g(x) }{ \lim_{x \to 4} h(x) } =\dfrac{0}{-2}=0.[/tex]

Answer:

A)  -2

Step-by-step explanation:

See the attached photo for explanation

Answer:

a) 0.0139; b) 0.1809; c) 0.4278

Step-by-step explanation:

We use a normal approximation to a binomial distribution for these problems.

The sample size, n, for each is 30; p, the probability of success, is 0.808.  This makes the mean, μ = np = 30(0.808) = 24.24.  The standard deviation,

σ = √(npq) = √(30(0.808)(1-0.808)) = √(30(0.808)(0.192)) = √4.65408 = 2.1573

For part a,

We are asked for P(X < 20).  Using continuity correction to account for the discrete variable, we find

P(X < 19.5)

z = (19.5-24.24)/(2.1573) = -4.74/2.1573 = -2.20

Using a z table, we see that the area under the curve to the left of this is 0.0139.

For part b,

We are asked for P(X = 24).  Using continuity correction, we find

P(23.5 < X < 24.5)

z = (23.5-24.24)/2.1573 = -0.74/2.1573 = -0.34

z = (24.5-24.24)/2.1573 = 0.26/2.1573 = 0.12

Using a z table, we see that the area under the curve to the left of z = -0.34 is 0.3669.  The area under the curve to the left of z = 0.12 is 0.5478.  The area between them is then

0.5478-0.3669 = 0.1809.

For part c,

We are asked to find P(25 ≤ X ≤ 28).  Using continuity correction, we find

P(24.5 < X < 28.5)

z = (24.5-24.24)/2.1573 = 0.26/2.1573 = 0.12

z = (28.5-24.24)/2.1573 = 4.26/2.1573 = 1.97

Using a z table, we see that the area under the curve to the left of z = 0.12 is 0.5478.  The area under the curve to the left of z = 1.97 is 0.9756.  The area between them is 0.9756 - 0.5478 = 0.4278.

Answer: [tex]=14a^3-21a^2+42a-35[/tex]

Step-by-step explanation:

You can multiply the polynomials by applying the Distributive property.

It is important to remember the Product of powers property, which states that:

[tex](b^a)(b^c)=b^{(a+c)[/tex]

Where b is the base and a and c are exponents.

It is also important to remember the multiplication of signs:

[tex](-)(-)=+\\(+)(+)=+\\(+)(-)=-[/tex]

Then:

Each term inside of the first parentheses must multiply each term inside of the second parentheses:

[tex](7a-7)(2a^2-a+5)=(7a)(2a^2)+(7a)(-a)+(7a)(5)+(-7)(2a^2)+(-7)(-a)+(-7)(5)\\\\=14a^3-7a^2+35a-14a^2+7a-35[/tex]

Finally, add like terms:

[tex]=14a^3-21a^2+42a-35[/tex]

It’s the third one C)

Answer:

(2, 8).

Step-by-step explanation:

(x - 2)^2 + (y - 6)^2 = 4

If x = 2 and y = 8 we have:

(2 - 2)^2 + (8 - 6)^2

= 0 + (2^2

= 4.

So it passes through the point (2,8).

The point through which the circle passes is:

                               (2,8)

The equation of the circle is given by:

[tex](x-2)^2+(y-6)^2=4[/tex]

We will check by putting each point in the equation and check which is equal to 4.

1)

(2,8)

when x=2 and y=8 we have:

[tex](2-2)^2+(8-6)^2=4\\\\i.e.\\\\0^2+2^2=4\\\\i.e.\\\\4=4[/tex]

Hence, the circle passes through the point (2,8).

2)

(5,6)

when x=5 and y=6 we have:

[tex](5-2)^2+(6-6)^2=4\\\\i.e.\\\\3^2+0^2=4\\\\i.e.\\\\9=4[/tex]

which is not true.

Hence, the circle does not pass through (5,6).

3)

(-5,6)

when x= -5 and y=6 we have:

[tex](-5-2)^2+(6-6)^2=4\\\\i.e.\\\\(-7)^2+0^2=4\\\\i.e.\\\\49=4[/tex]

which is not true.

Hence, the circle does not pass through (-5,6).

4)

(2,-8)

when x=2 and y= -8 we have:

[tex](2-2)^2+(-8-6)^2=4\\\\i.e.\\\\0^2+(-14)^2=4\\\\i.e.\\\\196=4[/tex]

Hence, the circle does not passes through the point (2,-8).

The Answer is 0.0636 c

Answer:

Boys=420

336+420= 756

Step-by-step explanation:

The total number of girls and boys are at the concert will be 756.

Since the ratio of girls to guys at the concert is 4 to 5 and there are 336 girls at a concert, then the total girls and boys are at the concert will be:

= 336 / (4/9)

= 336 × 9/4

= 756

Therefore, the total girls and boys are at the concert will be 756.
