Timothy purchased a computer for $1,000. The value of the computer depreciates by 20% every year.

This situation represents [a.) exponential decay, b.) exponential growth]

The rate of growth or decay, r, is equal to [c.) 0.8, d.) 1.2, e.)0.2

year.

So the value of the computer each year is [f.) 20 %, g.) 80%, h.) 120%] of the value in the previous year.

It will take [i.) 3, j.) 2, k.) 4, l.) 5.] years for the value of the computer to reach $512.

This situation represents [a.) exponential decay

The rate of growth or decay, r, is equal to  c.) 0.2

So the value of the computer each year is g.) 80% of the value in the previous year.

It will take [i.) 3 years for the value of the computer to reach $512.

Step-by-step explanation:

Since the value depreciates each year, it represents exponential decay.

The rate of growth or decay, r, is equal to

Depreciates 20%, so r = 0.2.

So the value of the computer each year is ... of the value in the previous year,

Depreciates 20%, so it is 100% - 20% = 80% of the value in the previous year.

It will take x years for the value of the computer to reach $512.

The value of the computer after x years is given by:

In which V(0) is the initial value and r is the decay rate. So

We want to find x for which V(x) = 512. So

Applying log to both sides:

So it will take 3 years.

don't know what that says sorry i can't you

step-by-step explanation:

idk what it says

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
