Given the radius r and the tangent line AB, the length of the line OA is 24 units

<h3>How to determine the length OA?</h3>

The radius r and the tangent line AB meet at a right angle.

By Pythagoras theorem, we have:

AB² = OA² + r²

So, we have:

24² = OA² + 7²

Rewrite as:

OA² = 24² - 7²

Evaluate

OA² = 527

Take the square root of both sides

OA = 23

Hence, the length of OA is 24 units

The formula for finding the area of a rug: A = s^2

Plugging in the values we know, we can solve for s.

79 = s^2

Take the square root of both sides.

\sqrt{79} = s

\sqrt{79} is approximately equal to 8.89

So, 8.89 feet is the answer.

\bf \begin{array}{ccllll}&#10;\$&minutes\\&#10;\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\&#10;920,000&46,000,000\\&#10;x&1&#10;\end{array}\implies \cfrac{920,000}{1}=\cfrac{46,000,000}{x}
so solve for "x", to see how much is the company paying for the purchase of 1 minute

now, they're plan to sell the minute for 8cents, how much is the profit?
that is, the difference from their cost of the cents to the planned selling price.

bear in mind, is 46,000,000 minutes, so whatever value you get for 1minute,
you need to multiply it for 46,000,000 to get the actual cost.

and the revenue from the sell of 8cents per minute, is of course, 8 * 46,000,000

profit = revenue - cost

Answer:

135

Step-by-step explanation:

The given expression is

\frac{2 {x}^{2} }{x} +x(100 - 15x)

From the question, x=5

So,by substitution,we obtain

=\frac{2({5}^{2})}{5} +5(100 - 15(5))

=\frac{2(25)}{5} +5(100 - 75))

=2(5)+5(25)

= 10+125

= 135

Hence the answer is 135
