An account earns simple interest.

$925 at 2% for 2.4 years
a. find the interest earned.

$

b. find the balance of the account.

$

interest = 925 x 0.02*2.4 = 44.40

balance = 925 + 44.40 =969.40

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
