9W + W^2 + 20 using the foil method
3x+8.5 =2.5x + 14.5
subtract 2.5x from each side
.5x + 8.5 = 14.5
subtract 8.5 from each side
.5x =6
multiply by 2
x =12
at 12 weeks they will be the same height
Choice B
Answer:
FV= $11,156.94
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $7,000
Number of periods (n)= 8 years
Interest rate (i)= 6% compounded annually
<u>To calculate the future value (FV), we need to use the following formula:</u>
FV= PV*(1 + i)^n
FV= 7,000*(1.06^8)
FV= $11,156.94
So, We Need To Examine The Problem. So, We Know That We Need To Find The Volume Of A Rectangular Prism. We Also Know That The Dimensions Are 4.9 • 3.8 • 5.4.
So, We Need To Remember The Formula For Volume Of A Rectangular Prism.
V = B • W • H
So, we need to plug in the known values.
V = 4.9 • 3.8<span> • 5.4.
So, Lets Solve.
4.9 • 3.8 = 18.62
18.62 * 5.4 = 100.548 cm²
Now We Have:
V = 100.548cm²
It Rounds To 100.5cm²</span>
Mean = (1+1+2+3+3+3+4+5)/8 = 22/8 = 2.75
answer
mean = 2.75
