Answer:
FV= PV*(1+i)^t
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $2,000
Interest rate (i)= 3.2% = 0.032
Number of periods= t
<u>To calculate the future value (FV) of the investment, we need to use the following formula:</u>
<u></u>
FV= PV*(1+i)^t
F<u>or example, Susan invests for 4 years:</u>
FV= 2,000*(1.032^4)
FV= $2,268.55
The function of the trapezoid area is:
A(x)=(B+b)*h/2
Where B and b are the bases and h is the height.
With the given data: h=10 B and b =7 and x (it may vary which one is bigger)
-----------
So that function becomes:
A(x)=(7+x)*10/2
A(x)=(7+x)*5
----------
So if you want the inverse function, you have to operate to find x:
A(x)/5=7+x
A(x)/5-7=x
----------
So the new function is:
x(A)=A/5-7
Answer:
1500 calories
Step-by-step explanation:
2400 is 100% of in this case, 8/8
So then we know that 1/8 of 2400 is 300 because we just divide it by 8. Sarah eats 5/8 that much so we multiply 300 by 5 which gives us 1500
f(3) = 1
substitute x = 3 into f(x)
f(3) = (2 × 3) - 5 = 6 - 5 = 1
