Answer:

Surface area of  Torrid Zone (cylinder shape) = 80,897,143 miles² (Approx)

Step-by-step explanation:

Given:

Radius of the Earth = 3,960 miles

Find:

Surface area of  Torrid Zone (cylinder shape) = ?

Computation:

We know that, distance between two tropics is 3,250 miles.

So, Height = 3,250 miles

Surface\ area\ of\ Torrid\ Zone=2\pi rh\\\\Surface\ area\ of\ Torrid\ Zone=2\times \frac{22}{7}\times 3,960 \times 3,250\\\\Surface\ area\ of\ Torrid\ Zone=80,897,142.9

Surface area of  Torrid Zone (cylinder shape) = 80,897,143 miles² (Approx)

$1689 invested for 4 years at 3% compounded annually ?
Ira Lisetskai [31]

The amount gotten after $1689 invested for 4 years at 3% compounded annually is $1901

The amount of money gained after an investment is compounded is given by:

A=P(1+\frac{r}{n} )^{nt}

Where P is principal, A is the final amount, r is the rate, n is the number of times compounded per period and t is the time

Given that P = $1689, t = 4, r = 3% = 0.03, n = 1, hence:

A=P(1+\frac{r}{n} )^{nt}\\\\A=1689(1+\frac{0.03}{1} )^{4*1}\\\\A=\$1901

The amount gotten after $1689 invested for 4 years at 3% compounded annually is $1901

A) The linear model represents the height, f(x), of a water balloon thrown off the roof of a building over times, x measured in
Brums [2.3K]

From the given linear function, we have that:

A. The function is constant on the following interval: B.2 ≤ x ≤ 5.

B. The function is increasing on the following interval: A.0 ≤ x ≤ 2.

C. The function is decreasing the fastest on the following interval: D.5 ≤ x ≤ 6.

D. The justification for the previous item is: D.5 ≤ x ≤ 6 is the interval where the slope is the steepest.

<h3>When a function is constant?</h3>

A function is constant when it's graph is an horizontal line, hence in this problem the function is constant for two intervals.

  • 2 ≤ x ≤ 5.
  • 10 ≤ x ≤ ∞.

Hence, in item A, option B is correct.

<h3>When a function is increasing?</h3>

A function is increasing on the intervals that y is increasing while x increases, that is, the function is moving right and up.

Hence, in item B, option A is correct.

<h3>When a function is decreasing?</h3>

A function is decreasing on the intervals that y is decreasing while x increases, that is, the function is moving right and down.

The decrease is faster when the division of the change in the output by the change in the input has the lower value(greater absolute negative).

Hence:

  • In item 3, option D is correct.
  • In item 4, option D is correct.
