Answer:
Exponential Function: 
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
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
The above equation is exponential function that describes the amount in the account after time t in years
Now, for t = 1
A= $ 13,524.32
t=2
A= $ 14,374.99
t= 5
A= $ 17,261.69
t=10
A= $ 23,417.64
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.
Answer:
209.1 cm2
Step-by-step explanation:
the area of the circle around the rectangle is 113.1 cm2 and the area of the rectangle is 12x8=96cm and 113.1+96=209.1
Answer:
1 chair cost=$452
so of 15 chairs=$452×15=$6780
1 table cost=$1750
so cost of 40 tables=$1750×30=$5250
Total cost=$6780+$5250=$12,030
Step-by-step explanation:
