The value of this car when it is 9 years old is equal to $16,757.00.

<h3>How to calculate the value?</h3>

In order to determine the value of this car when it is 9 years old, we would use an exponential function which also relates to compound interest as follows:

A = P(1 - r)^t

Substituting the given parameters into the formula, we have;

A = 32,200(1 - 0.07)^9

A = 32,200(0.93)^9

A = 32,200 × 0.5204

A = $16,757.00.

What is the completely factored form of t4 − 16?
Mashcka [7]

we know that

A difference of squares problem can be factored as follows:

a^{2}-b^{2} =(a+b)(a-b)

in this problem we have

t^{4}-16

Applying difference of squares

t^{4}-16=(t^{2}-4)( t^{2}+4)

the term

(t^{2}-4)=(t+2)(t-2)

substitute

(t^{2}-4)( t^{2}+4)=(t+2)(t-2)( t^{2}+4)

therefore

<u>the answer is</u>

(t+2)(t-2)( t^{2}+4)

The volume of a sphere can be found using the formula V = πr . If the sphere has a diameter of 10x y z mm, what is the volume of
viva [34]

Answer:

<em>500πx³y³z³ </em>

Step-by-step explanation:

Volume of a sphere = 4πr³

r is the radius of the sphere

Given

Diameter of the sphere = 10xyz mm

Radius = diameter/2

Radius = 10xyz/2

Radius = 5xyz

Substitute the radius into the formula

Volume of the sphere = 4π(5xyz)³

Volume of the sphere = = 4π(125)x³y³z³

Volume of the sphere = 500πx³y³z³

<em>Hence the volume of the sphere is 500πx³y³z³ mm³</em>
