Answer:

Option C (x < -5/4)

Step-by-step explanation:

((2 - 5x)/(-3)) + 4 < -x.

Take LCM on LHS:

(2 - 5x - 12)/(-3) < -x.

Multiplying -3 on both sides (this will also flip the inequality):

-5x - 10 > 3x.

Adding 10 on both sides and subtracting -3x on both sides:

-8x > 10.

Dividing -8 on both sides (this will also flip the inequality):

x < -5/4.

Therefore, Option C is the correct answer!!!

Answer:

B. 13.26

Step-by-step explanation:

To go from the Degree-Minute-Second (DMS) system to a numeric one, we simply use this formula:

numeric = d + (min/60) + (sec/3600)

Where you take the degree number as is (13 in our case), then you divide the number of minutes by 60 (15 in our case) and the number of seconds by 3600 (36 in our case) and you add everything together.

So, if we plug in our numbers, we have

numeric = 13 + (15/60) + (36/3600)

numeric = 13 + 0.25 + 0.01

numeric = 13.26

The value of [p] at equilibrium is equivalent to 43.12.

At equilibrium, the demand is equal to supply. Mathematically, we can write -

D{x} = S(x)

Given is are the demand and supply equations.

We have the demand and supply equations as -

D{p} = (-5/8)p + 35

S{p} = (6/5)p - 44

Now, at equilibrium, we can write -

D{p} = S{p}

(-5/8)p + 35 = (6/5)p - 44

(6/5)p + (5/8)p = 35 + 44

p{(48 + 25)/40} = 79

p(73/40) = 79

p = (79 x 40)/73

p = 43.12

Therefore, the value of [p] at equilibrium is equivalent to 43.12.

Have a great day!

The length, to 1 decimal place, of the arc that subtends an angle of 5.4 radians at the center of a circle with a radius of 7 cm is 37.8 cm.

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

It is given that:

The arc subtends an angle of 5.4 radians at the center of a circle with a radius of 7 cm.

As we know, the relationship between radius of the circle, central angle, and arc length is:

s = rθ

r = 7 cm

θ = 5.4 radians.

When two lines or rays converge at the same point, the measurement between them is called an "Angle."

s = 7×5.4

s = 37.8 cm

Thus, the length, to 1 decimal place, of the arc that subtends an angle of 5.4 radians at the center of a circle with a radius of 7 cm is 37.8 cm.

Answer:

24 pieces

Step-by-step explanation:

Divide:

 6 sandwiches

---------------------------- = 24 pieces

1/4 sandwich/piece

Divide 50 by 2 so 25 then divide that by 2 so 12.5 =x

The equation 2x² = 50 has two solutions, x = 5 and x = -5.

The equation 2x² = 50 can be solved algebraically by dividing both sides by 2 and then taking the square root of both sides. This gives us two solutions, x = 5 and x = -5.

Another way to solve this equation is to factor the left side. We can see that 2x² = 2(x²). We can also factor x² as (x)(x). This gives us the following equation:

2(x)(x) = 50

Dividing both sides by 2, we get:

(x)(x) = 25

Taking the square root of both sides, we get:

x = ±5

Therefore, the two solutions to the equation 2x² = 50 are x = 5 and x = -5.

We can check our answer by substituting x = 5 and x = -5 back into the original equation.

2(5)² = 50

2(25) = 50

50 = 50

This is true.

2(-5)² = 50

2(25) = 50

50 = 50

This is also true.

Therefore, our solutions are correct.

Final answer:

To calculate the original loan amount for Scott, who paid $750 in interest at a 3% rate, we use the formula for simple interest and determine that the original loan amount was $25,000.

Explanation:

If Scott pays $750 in interest at a rate of 3%, to find out the original amount of the loan, we can use the formula I = PRT, where I stands for interest, P is the principal amount (the original loan amount), R is the rate of interest, and T is the time in years. Since Scott already knows the interest and the rate, we can rearrange this formula to solve for P:  P = I / (RT).

In this case, we assume the time T to be 1 year, since no specific time was given. The calculation would be:

P = $750 / (0.03 * 1)

P = $750 / 0.03

P = $25,000

So, the original loan amount Scott must have taken out is $25,000.

Answer:

There's a lot of them.

There are many different ways to calculate [tex]\pi[/tex]. The ones used by computers to generate tons of digits are usually infinite series.

The series that has been prominent in recent records for the most digits of pi is the Chudnovsky algorithm.

The algorithm is this:

[tex]\frac{1}{\pi}=12\sum_{k=0}^{\infty}\frac{\left(6k\right)!\left(545140134k+13591409\right)}{\left(3k\right)!\left(k!\right)^3\left(640320\right)^{3k+\frac{3}{2}}}[/tex]

For faster performance, it can be simplified to this:

[tex]\frac{426880\sqrt{10005}}{\pi}=12\sum_{k=0}^{\infty}\frac{\left(6k\right)!\left(545140134k+13591409\right)}{\left(3k\right)!\left(k!\right)^3\left(-262537412640768000\right)^k}[/tex]

Other algorithms have been used, but right now this is the one that is being used to set the recent records.

There are also some approximations that are used because they are very easy to calculate.

first, [tex]\frac{22}{7}[/tex] can be used to calculate a fairly accurate pi, but a better rational approximation is [tex]\frac{355}{113}[/tex] This fraction is actually accurate to 6 digits and it is the best approximation of [tex]\pi[/tex] in simplest form and with a denominator below 30,000.

There are several other approximations and if you want to learn more I would recommend looking at the Wikipedia page which has tons of algorithms for pi.

Answer: [tex]ln-10[/tex] is the length of Santa Monica and [tex]ln>10[/tex]

Step-by-step explanation:

Let the length of Nina Pinta be ''ln'

According to question, we have given that

the Santa Monica has a hull length that is 10 ft shorter than that of the Nina Pinta.

and 10 ft shorter than that of Nina Pinta is expressed as [tex]ln-10[/tex]

So, the length of Santa Monica be 'ln'-10'

Restriction on ln is that ln>10.

As Length of Santa Monica cannot be negative or equal to zero.

so, [tex]ln>10[/tex]

Hence, [tex]ln-10[/tex] is the length of Santa Monica and [tex]ln>10[/tex]

The speed of the Santa Monica, given the hull length of Nina Pinta as 'ln' and that Santa Monica is 10 ft lesser in hull length, can be represented by 1.34 * sqrt(ln - 10). The restriction on this is that ln must be greater than 10 ft.

The hull length of the Santa Monica is defined as ln - 10, where ln is the hull length of the Nina Pinta. The hull speed of the Santa Monica, according to the hull speed formula, is calculated as 1.34 times the square root of the hull length. Therefore, the hull speed of the Santa Monica in terms of the hull length of the Nina Pinta, ln, can be represented by the expression 1.34 * sqrt(ln - 10) where sqrt stands for 'square root'.

The restriction on the domain is that ln must be greater than 10 as the hull length cannot be negative.

3 × 12 = 36 ← number of boys

To find out how many apple pieces are in the bowl when 1/4 of 12 fruit pieces are apples, divide 12 by 4, which equals 3. So, there would be 3 apples in the bowl.

Understanding fractions is an important part of mathematics. In this scenario, we have a total of 12 pieces of fruit in a bowl and we want to find out how many of those are apple pieces if 1/4 of the fruit pieces are apples.

Since there's a total of 12 pieces, we divide this number into 4 equal parts (fractions strips) to determine what one quarter (1/4) of the bowl would contain.

To visualize this, you can draw a rectangle and divide it into 4 equal horizontal sections (fractions strips), because 1/4 means one part out of four equal parts. When you divide 12 by 4, you get 3. So, each section of your fraction strip would represent 3 pieces of fruit. This means that if 1/4 of the pieces are apples, there are 3 apples in the bowl.

Answer:

144°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° × (n - 2) ← n is the number of sides

Here n = 8 ( octagon ), hence

sum = 180° × 6 = 1080°

let the measure of 1 congruent angle be x

Then sum the 8 angles and equate to 1080

100 + 120 + 140 + 5x = 1080

360 + 5x = 1080 ( subtract 360 from both sides )

5x = 720 ( divide both sides by 5 )

x = 144

Thus each of the 5 congruent angles is 144°

Answer:

Step-by-step explanation:

Volume of the cylinder

= π(4)²(10)

= 160π in³

Volume of the cone

= 1/3 π(1)²(2)

= 2/3 π in³

Number of cones

= 160π ÷ 2/3 π

= 240

By calculating the volumes of both the original cylinder and one of the cones, we can determine that 80 solid right circular cones can be formed from the melted cylinder.

The question involves calculating the number of solid right circular cones that can be formed from melting and recasting a solid metal cylinder with given dimensions. First, we need to calculate the volume of the original cylinder and then the volume of one of the right circular cones, followed by dividing the volume of the cylinder by the volume of a cone to determine how many cones can be formed.

Step 1: Calculate the Volume of the Cylinder

The formula for the volume of a cylinder is V = πr²h, where r is the radius and h is the height (altitude). For the cylinder with a 4-inch radius and 10-inch altitude, the volume is V = π(4²)(10) = 160π cubic inches.

Step 2: Calculate the Volume of a Cone

The formula for the volume of a cone is V = ⅓πr²h, where r is the radius and h is the height. For a cone with a 1-inch radius and 2-inch altitude, the volume is V = ⅓π(1²)(2) = ⅓π cubic inches.

Step 3: Determine the Number of Cones Formed

To find the number of cones that can be formed, divide the volume of the cylinder by the volume of a cone: Number of cones = (160π) / (⅓π) = 80. Therefore, 80 solid right circular cones can be formed from the melted cylinder.

Answer:

the answer is A

Step-by-step explanation:

the formula is 2π rh +2πr^2

you put the values in

2π (6*15) +2π(6)^2

then you solve

180π+ 72π= 252π

For this case we have that by definition, the surface area of a cylinder is given by:

[tex]SA = 2 \pi * r * h + 2 \pi * r ^ 2[/tex]

Where:

A: It's the radio

h: It is the height of the cylinder

We have to:

[tex]r = 6 \ units\\h = 15 \ units[/tex]

Substituting:

[tex]SA = 2 \pi * 6 * 15 + 2 \pi * (6) ^ 2\\SA = 2 \pi * 6 * 15 + 2 \pi * (6) ^ 2\\SA = 180 \pi + 72 \pi\\SA = 252 \pi \ units ^ 2[/tex]

Answer:

[tex]f(x)=(x-2)^{\frac{1}{3}}-2[/tex] ⇒ answer B

Step-by-step explanation:

* Lets revise some transformation

- If the function f(x) translated horizontally to the right  

 by h units, then the new function g(x) = f(x - h)

- If the function f(x) translated horizontally to the left  

 by h units, then the new function g(x) = f(x + h)

- If the function f(x) translated vertically up  

 by k units, then the new function g(x) = f(x) + k

- If the function f(x) translated vertically down  

 by k units, then the new function g(x) = f(x) – k

* Now lets solve the problem

∵ f(x) = x^1/3

- f(x) shifted 2 units to the right

∴ f(x) = (x - 2)^1/3

- f(x) shifted 2 units down

∴ f(x) = (x - 2)^1/3 - 2

* [tex]f(x)=(x - 2)^{\frac{1}{3}}-2[/tex]

Answer:

B

Step-by-step explanation:

Given a function of a parabola (quadratic) in the form f(x) = x^2, we have a translated function as:

g(x) = a(x-b)^2

Where

The function given is p(x) = 3(x-8)^2

So it means that it is a vertical stretch with a factor 3 and the graph is shifted horizontally 8 units right

the correct answer is B

Start with

[tex]\vec v=x\,\vec\imath+y\,\vec\jmath[/tex]

as a template for the vector [tex]\vec v[/tex]. Its magnitude is 4, so

[tex]\|\vec v\|=\sqrt{x^2+y^2}=4[/tex]

Its component in the [tex]\vec\imath[/tex] direction is twice the component in the [tex]\vec\jmath[/tex] direction, which means

[tex]x=2y[/tex]

So we have

[tex]\sqrt{(2y)^2+y^2}=\sqrt{5y^2}=4\implies y^2=\dfrac{16}5\implies y=\pm\dfrac4{\sqrt5}[/tex]

and

[tex]x=\pm\dfrac8{\sqrt5}[/tex]

Lastly, rationalize the denominator:

[tex]\dfrac1{\sqrt5}\cdot\dfrac{\sqrt5}{\sqrt5}=\dfrac{\sqrt5}5[/tex]

So we end up with two possible answers,

[tex]\vec v=\pm\left(\dfrac{8\sqrt5}5\,\vec\imath+\dfrac{4\sqrt5}5\,\vec\jmath\right)[/tex]

Final answer:

The vector v with a magnitude of 4 and i-component being twice the j-component can be found by solving for y in the equation of magnitude based on the given conditions and then determining the i and j components accordingly. The result is the vector v = (8√5 i + 4√5 j) / 5.

Explanation:

To find a vector v whose magnitude is 4, and whose i-component is twice its j-component, we can let the i-component be 2y and the j-component be y. Using the Pythagorean theorem for two-dimensional vectors, we can write the equation for magnitude as v = √((2y)^2 + y^2). Given that the magnitude is 4, the equation becomes:

4 = √(4y^2 + y^2)

4 = √(5y^2)

16 = 5y^2

y^2 = ⅔

y = √(⅔)

y = √(⅔)

y = √(⅔)

y = √(⅔)

y = √(⅔)

y = √(⅔)

(2.0 s) gives us the direction in unit vector notation. The magnitude of the acceleration is à(2.0 s)| = √√5.0² + 4.0² + (24.0)² = 24.8 m/s².

Using the value of y we calculated, the components of vector v are:

i-component = 2y = 2(⅔) = 8√5 / 5

j-component = y = ⅔ = 4√5 / 5

So the vector v can be expressed as v = (8√5 i + 4√5 j) / 5.
