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.

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

he spend 5.1 minutes chatting with his friends

step-by-step explanation:

2/5+1/2=9/10

6/1-9/10=5 1/10

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:

step-by-step explanation:   divide the numerator by the denominator to get the decimal

it would still be 193

if divide by 100 then 1.93

i am not sure
