Answer: -8.93

Step-by-step explanation:

Given the function:

N(X) = 90(0.86)^x+ 69

X in the interval [0, 6]

For X = 0

N(0) = 90(0.86)^0 + 69

90 + 69 = 159

For X = 6

N(6) = 90(0.86)^6 + 69

90(0.404567235136) + 69

= 105.41105116224

Therefore, average change of change in temperature ;

(temp 2 - temp 1) / ( time 2 - time)

(105.41105116224 - 159) / (6 - 0)

= - 53.58894883776 / 6

= - 8.93149147296

= - 8.93

Fannie has a life insurance policy that will pay her family $24,000 per year if
gregori [183]

Answer:

The rate is 2% per year.

Step-by-step explanation:

<em>It is given that sum to be $1200000.</em>

<em>The interest per year to be received is $24000.</em>

<em>Let the rate of interest be "r".</em>

The amount interest is given by the formula,

(Interest) = (Principle amount)(\frac{Rate}{100})(Time)

24000 = (1200000)(\frac{r}{100})(1)

r = \frac{24000}{12000} = 2

Thus the rate of interest is given by 2% per year.
