Suppose that $12,724 is invested at an interest rate of 6.1% per year, compounded continuously. Find the exponential function th
olchik [2.2K]

Answer:

Exponential Function: A= P* e ^ {0.061t}

Balance after

t=1 $ 13,524.32

t=2 $ 14,374.99

t=5 $ 17,261.69

t=10 $ 23,417.64

Step-by-step explanation:

Formula used to find amount in the account after time t, given the interest rate is compounded continuously

A= Pe^r^t

where: P= principal amount or amount invested

r= interest rate

t= time

A= amount after time t

in our question we are given:

P=$12,724

r= 6.1% or 0.061

A= 12724 * e ^ (^0^.^0^6^1^)^t

The above equation is exponential function that describes the amount in the account after time t in years

Now, for t = 1

A= 12724 * e ^ {0.061 * 1}

A= $ 13,524.32

t=2

A= 12724 * e ^ {0.061 * 2}

A= $ 14,374.99

t= 5

A= 12724 * e ^ {0.061 * 5}

A= $ 17,261.69

t=10

A= 12724 * e ^ {0.061 * 10}

A= $ 23,417.64

The length of a rectangle is 3 centimeters less than twice its width. If the perimeter of the rectangle is 18 centimeters. find
Ede4ka [16]

Answer:

  • equation: w +(2w -3) = 18/2
  • length = 5 cm
  • width = 4 cm

Step-by-step explanation:

Let w represent the width in cm. Then the length is 2w-3, 3 cm less than twice the width. The perimeter is twice the sum of these, so the sum of length and width is half the perimeter:

  w + (2w -3) = 18/2

  3w -3 = 9 . . . . collect terms

  3w = 12 . . . . add 3

  w = 4 . . . . divide by 3

  2w-3 = 2·4 -3 = 5 . . . . length

The equation is w + (2w -3) = 18/2; the length is 5; the width is 4.
