What is the average rate of change for the quadratic function from x=-1 to x=4?
Mazyrski [523]

Answer:

1

Step-by-step explanation:

f(x) = x^2 - 2x - 4

when x = -1, f(-1) = (-1)^2 - 2(-1) - 4 = 1 + 2 - 4 = -1

when x = 4, f(4) = (4)^2 - 2(4) - 4 = 16 - 8 - 4 = 4

The average rate of change from x = -1 to x = 4:

  f(4) - f(-1)          4 - (-1)              5

---------------- = -----------------=   --------  = 1

 x4 - x1               4 - (-1)              5

Answer

The average rate of change = 1

You wish to buy a house for ​$295987. The bank offers you a mortgage loan of 3.7​% for 25 years. How much will your monthly paym
Allisa [31]

Answer:

Monthly payments: $2446.92

Total expenditure: $734,076.88

Step-by-step explanation:

As the compounding frequency is not stated, it is supposed to be annualy.

<em>The total accumulated value T, including the loan L and the interest is given by the formula </em>

T=L(1+\frac{r}{n})^{nt}

where

L = Amount of the loan

r = nominal interest per year. In this case, 0.037

n = compounding frequency, in this case 1 year

t = the length of time the interest is applied. In this case, 25                      years.

The total amount after 25 years will be

T=295987(1+0.037)^{25}=295987(1.037)^{25}=734076.88

There are 25 times 12 = 300 months in 25 years, so the monthly payments would be

\frac{734076.88}{300}=\$2446.92

After the life of the loan, if there are no additional commissions  or expenditures, you would have spent the amount of the loan plus interest, that is to say, the amount T previously computed  

$734076.88
