Answer: $0.42
Step-by-step explanation:
The rate at which the average cost of 1 gallon of gasoline is increasing is exponential. We would apply the formula for exponential growth which is expressed as
y = b(1 + r)^ t
Where
y represents the cost after t years.
t represents the number of years.
b represents the initial cost.
r represents rate of growth.
From the information given,
b = $0.31
r = 3% = 3/100 = 0.03
t = 1972 - 1962 = 10 years
Therefore,
y = 0.31(1 + 0.03)^10
y = 0.31(1.03)^10
y = $0.42
Answer:
4186.67 cubic mm=V
Step-by-step explanation:
The volume of a sphere can be found using the equation, 
. It gives us the diameter but we need the radius. To find the radius just divde the diameter by 2, so the radius of the sphere is 10mm.
=V
=V
(3140)=V
4186.67 cubic mm=V
Answer:
a. y = 128(1 - 0.50)
Step-by-step explanation:
Answer:
He would have $111,050.77 in the IRA.
Step-by-step explanation:
<u>What we know</u>:
The PMT is $1000
Rate of Interest (i in the formula) is 6.4% or 0.064 in decimal form
Number of periods (n) is 12
-
<u>Equation (Future Value Formula)</u>:
FV = PMT ( (1+i)^n -1) / i)
= 1000 ( (1+0.064)^12 -1) / 0.064)
FV = 17,269.22 (rounded)
-
A stands for amount
T stands for time period which is 30
<u>Finding IRA</u>:
A = FV (1+i)^t
= 17,269.22 (1+0.064)^30
= $111,050.77
