Answer:
4u+44
Step-by-step explanation:
The number 4 on the outside of the parentheses is being multiplied by everything within the parentheses, resulting in a product of 4u+44
Answer:the simple interest rate of the loan is 13.3%
Step-by-step explanation:
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the loan.
P represents the principal or amount taken as loan
R represents interest rate
T represents the duration of the loan in years.
From the information given,
P = $16,800
R = ?
T = 54 months = 54/12 = 4.5 years
I = 26854.80 - 16800 = $10054.8
Therefore
10054.8 = (16800 × R × 4.5)/100
10054.8 = 756R
R = 10054/756
R = 13.3%
We can model the function between a and b as a linear function of negative slope because it is a short interval and the change is not very significant.
We have then that the average rate of change in that interval is:
m = (f (a) - f (b)) / (a-b)
Substituting the values:
m = (34.25 - 26) / (2.5-3.6)
m = -7.5
Negative, because the function decreases in that interval.
Answer:
a reasonable estimate of the average rate of change of the height of the rocket, in meters per second, between a and b seconds is:
m = -7.5 m / s
