Cindy is baking a 2-layer cake. The top layer has a diameter of 8 inches and the bottom layer has a diameter of 10 inches. What
Alenkinab [10]

The difference in area between the top surfaces of the two cakes is 28.26 inches²

<h3>Area of a circle</h3>
  • area = πr²

where

r = radius

Therefore,

area of top layer = πr²

d = 2r

r = d / 2

r = 8 / 2

r = 4 inches

area of top layer = 3.14 × 4²

area of top layer = 3.14 × 16

area of top layer = 50.24 inches²

area of the bottom layer = πr²

r = 10 / 2 = 5 inches

area of the bottom layer = 3.14 × 5²

area of the bottom layer = 3.14 ×25

area of the bottom layer = 78.5 inches²

Difference in area between the top surfaces of the two cakes can be found as follows:

  • 78.5 - 50.24 = 28.26 inches²

Find the formula for an exponential function that passes through the two points given.
goldenfox [79]

Answer:

y = 7(3^x)

Step-by-step explanation:

Given

(x_1,y_1) = (0,7)

(x_2,y_2) = (4,567)

Required

Determine the formula

An exponential function is of the form:

y = ab^x

For point (x_1,y_1) = (0,7)

7 = ab^0

7 = a*1

7 = a

a = 7

For point (x_2,y_2) = (4,567)

567 = ab^4

Substitute 7 for a

567 = 7*b^4

Divide both sides by 7

81 = b^4

Take 4th root of both sides

\sqrt[4]{81} =\sqrt[4]{b^4}

\sqrt[4]{81} =b

b = \sqrt[4]{81}

b = 3

Substitute 7 for a and 3 for b in y = ab^x

y = 7 * 3^x

y = 7(3^x)

HELP you purchase a car using a $22,000 loan with a 6% simple interest rate for 5 years
Hunter-Best [27]

Answer:  (a) $6,600

                (b) $28,600

<u>Step-by-step explanation:</u>

Interest (I) = Principal (P) x rate (r) x time (t)

I = 22,000(0.06)(5)

 = 6,600


Accrued (A) = Principal (P) + Interest (I)

A = 22,000 + 6,600

  = 28,600
