Answer: B. $5005

Step-by-step explanation:

The equation of parabola is given by  

                                         (X-h)^2 = 4p(Y-k)^2

2p = 30 - 0

p = 15

4p = 4 × 15

    = 60

In this case h = 0

So, we have (h,p) = (0,15)

So we get  

We have equation: x^2 = 60(y-15)

y = x^2 / 60 + 15

Answer:

[tex]\displaystyle{\dfrac{5x-12}{(x+3)(x-3)} }[/tex]

Step-by-step explanation:

We are given the expression:

[tex]\displaystyle{\dfrac{3}{x^2-9} + \dfrac{5}{x+3}}[/tex]

First, factor the denominator [tex]\displaystyle{x^2-9}[/tex] to [tex]\displaystyle{(x+3)(x-3)}[/tex] via difference of two squares:

[tex]\displaystyle{\dfrac{3}{(x+3)(x-3)} + \dfrac{5}{x+3}}[/tex]

Next, multiply the expression 5/(x+3) by [tex]\displaystyle{x-3}[/tex] both denominator and numerator:

[tex]\displaystyle{\dfrac{3}{(x+3)(x-3)} + \dfrac{5(x-3)}{(x+3)(x-3)}}[/tex]

Add both together since they have same denominator now:

[tex]\displaystyle{\dfrac{3+5(x-3)}{(x+3)(x-3)} }[/tex]

Simplify the numerator:

[tex]\displaystyle{\dfrac{3+5x-15}{(x+3)(x-3)} }\\\\\displaystyle{\dfrac{5x-12}{(x+3)(x-3)} }[/tex]

Therefore, the sum is:

[tex]\displaystyle{\dfrac{5x-12}{(x+3)(x-3)} }[/tex]

Answer:

age of son= X

Father's age =3x

After 10 years , father's age= 3x +10

Son's age = X+10

Operations:

3x + 10 = 2x + 20

X= 10

Therefore, present age of son= 10 years

Father's present age = 30 years

After 10 years son will be 20 years and the father 40 yes which is double

Answer:

376.8 [tex]units^{2}[/tex]

Step-by-step explanation:

There are a lot of moving parts.  We need to find the area of the bottom of the circle the center and the top circle.

The top and the bottom will be the same.

The area of a circle:

a = [tex]\pi[/tex][tex]r^{2}[/tex]

a = 3.14([tex]5^{2}[/tex])

a = 3.14(25)

a =78.5  

The center:  Think of this as a label on soup can.  If you tear the label off it would be a rectangle.  To find the area we would multiply the height of the can by the circumference of the circle.  They tell us the height is 7 and we can calculate the circumference.

C = [tex]\pi[/tex]d The d is the diameter it is 2 of the radiuses.  

C = [tex]\pi[/tex]10

C = 3.14(10)

C = 31.4

Now we multiply 31.4 and 7 together to find the area of the center of the cylinder.

(31.4)(7) = 219.8

The total area:

top 78.5

center 219.8

bottom 78.5

Total 376.8

Step-by-step explanation:

To solve this question, we simply need to divide the total amount of students by 8% to find out how many students were absent and how many were present.

However, we can't simply multiply it by 8%, so we need to turn that into a decimal.

8% - 0.08

Multiply:

355 x 0.08

= 28.4

Round:

28 kids were absent

Subtract:

355 - 28

= 327

This means that 28 kids were absent, and 327 kids were present.

The number of terms in the given arithmetic sequence is n = 10. Using the given first, last term, and the common difference of the arithmetic sequence, the required value is calculated.

The general form of the nth term of an arithmetic sequence is

an = a1 + (n - 1)d

Where,

a1 - first term

n - number of terms in the sequence

d - the common difference

The given sequence is an arithmetic sequence.

First term a1 = [tex]1\frac{1}{2}[/tex] = 3/2

Last term an = [tex]2\frac{1}{2}[/tex] = 5/2

Common difference d = 1/9

From the general formula,

an = a1 + (n - 1)d

On substituting,

5/2 = 3/2 + (n - 1)1/9

⇒ (n - 1)1/9 = 5/2 - 3/2

⇒ (n - 1)1/9 = 1

⇒ n - 1 = 9

⇒ n = 9 + 1

∴ n = 10

the surface area of the sphere is π/4 cm^3

It is important to know the formula for surface area and volume of a sphere

Surface area = [tex]\frac{4\pi }{r^2}[/tex]

Volume = [tex]\frac{4}{3} \pi r^3[/tex]

First, let's determine the value of radius, r

The value for volume was given as  256/3π cm3.

[tex]\frac{256}{3} \pi = \frac{4}{3} \pi r^3[/tex]

Pi cancels out and we have cross multiply to get the radius

[tex]256 * 3 = 4 * 3 r^3[/tex]

[tex]12r^3 = 768[/tex]

Make r the subject of the formula

[tex]r = \sqrt[3]{\frac{768}{12} }[/tex]

[tex]r = \sqrt[3]{64}[/tex]

r = 4

Let's substitute to find the surface area

The weight of a 36-inch piece of PVC pipe is 0.20 pounds

The given parameters about the 36-inch piece of PVC pipe are

Height, h = 36 inches

Outside diameter, D = 0.82 inches

Inside diameter, d= 0.75 inches

The volume of the PVC pipe is then calculated as:

V = πh(D/2)^2 - πh(d/2)^2

Substitute the known parameters in the above equation

V = 3.14 * 36 * (0.82/2)^2 - 3.14 * 36 * (0.75/2)^2

Evaluate the quotients

V = 3.14 * 36 * 0.41^2 - 3.14 * 36 * 0.375^2

Evaluate the exponents

V = 3.14 * 36 * 0.1681 - 3.14 * 36 * 0.140625

Evaluate the products

V = 19.002024 - 15.89625

Evaluate the difference

V = 3.105774 cubic inches

From the question, we have:

Weight =  0.063 pounds per cubic inch

So, the total weight is

Total weight = 3.105774 cubic inches * 0.063 pounds per cubic inch

Evaluate the product

Total weight = 0.195663762 pounds

Total weight = 0.20 pounds

First of all, we will find the each side of cube A and B as:

[tex]A^{3} = 27[/tex]

[tex]\sqrt[3]{A^{3} } = \sqrt[3]{27}[/tex]

A = 3

[tex]B^{3} = 125[/tex]

[tex]\sqrt[3]{B^{3} } = \sqrt[3]{125}[/tex]

B = 5

Now, we will find base area of both cubes as:

[tex]\frac{Base area of B}{Base area of A} = \frac{B^{2} }{A^{2} }[/tex]

[tex]\frac{Base area of B}{Base area of A} = \frac{5^{2} }{3^{2} }[/tex]
