C.is decrease by 1 foot every 500 miles D. Is decrease by 1 foot every 1000 miles

Tasya [4]

Answer:

Option A

Step-by-step explanation:

Slope of a line passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by,

Slope = $\frac{y_2-y_1}{x_2-x_1}$

Line shown in the graph is passing through two points (2, 8000) and (4, 7000).

Therefore, slope of the given line = $\frac{8000-7000}{2-4}$

= -500 feet per mile

Which means, altitude decreases by 500 ft every mile.

(Negative sign represents the decrease)

Option A is the correct option.

Answer:

see below

Step-by-step explanation:

The exponent rules that apply are ...

(a^b)(a^c) = a^(b+c)

a^-b = (1/a)^b

(a^b)^c = a^(b·c)

_____

These let you rewrite the given function as ...

f(x) = (3^(2x))(3^1) = 3(3^(2x)) = 3(3^2)^x = 3·9^x

and

f(x) = 3^(2x+1) = (3^-1)^(-(2x+1)) = (1/3)^-(2x+1)

a rocket is 1 mile above thw earth in 30 seconds and 5 miles above the earth in 2.5 minutes what is the rockets rate of change i

Veronika [31]

Rate of Change:

At 1 mile in 30 seconds.
At 5 miles in 2.5 minutes. 2.5 minutes = 2.5*60 = 150 seconds.

Rate of change = Change in height / Change in time

= (h₂-h₁)/(t₂-t₁)

= (5 -1) /(150 -30) = 4/120 = (1/30) = 0.0333 miles per second.

   = (1/30) miles per second or 0.0333 miles per second.

To have the answer in miles per minute.

   (1/30) miles per second = (1/30) miles/second.

60 seconds = 1minute
1 second = (1/60) minute.

(1/30) miles/second = (1/30) miles/(1/60)minute
   = (1/30) *60 miles / minute
   =    2 miles per minute.

Income Suppose income from an endowment is generated at the annual rate of $42,000 per year. Find the capital value of this endo

Mrac [35]

Answer:

Capital value after 1 year will be equal to $45150

Step-by-step explanation:

We have given principal amount P = $42000

Rate of interest r = 7.5 %

Time t = 1 year

Capital value is given by $A=P(1+\frac{r}{100})^n$

So $A=42000\times (1+\frac{7.5}{100})^1$

$A=42000\times 1.075=45150$

So capital value after 1 year will be equal to $45150
