Answer:

121°

Step-by-step explanation:

  • We have been given a chord and tangent to a circle, and also a minor arc measure that is equal to 118°
  • We know that; An angle formed by a secant and tangent of circle is half of the measure of intercepted arc.

Therefore; ∠ x = 1/2 mABC

  • We can find intercepted arc by subtracting minor arc measure from 360 degrees because minor and major arcs add up to 360 degrees.

Thus;<em> 360° - 118° = 242°</em>

<em>Using the formula; ∠ x = 1/2 mABC</em>

<em>Then; d = 242/2</em>

            = 121°

A farmer who has fixed amounts of land and capital finds that total product is 24 for the first worker hired, 32 when two worker
ruslelena [56]

Answer:

A. 8.

Step-by-step explanation:

The marginal product is the increase in output (units produced) resulting from employing one more worker. Therefore, the marginal product of the second worker (M2) is given by the difference between the total product with two workers and the total product with one worker.

M_2 =32-24\\M_2 =8

The answer is A. 8.

F(x) = x^2+1 and g(x) = x-4 <br> (f/g)(5)=
Nezavi [6.7K]

The value of the composite function is (f/g)(5)= 26

<h3>How to evaluate the composite function?</h3>

The functions are given as:

f(x) = x^2+1 and g(x) = x-4

To calculate the composite function, we use the following formula

(f/g)(x)= f(x)/g(x)

So, we have:

(f/g)(5)= f(5)/g(5)

Calculate f(5) and g(5)

f(5) = 5^2+1 and g(5) = 5-4

This gives

f(5) = 26 and g(5) = 1

Substitute f(5) = 26 and g(5) = 1 in (f/g)(5)= f(5)/g(5)

(f/g)(5)= 26/1

Evaluate

(f/g)(5)= 26

Hence, the value of the composite function is (f/g)(5)= 26
