Answer:

Step-by-sf(-5)=17

tep explanation:

Let Q(x) be the quotient of \frac{f(x)}{x+5}.

Let R be the remainder. R is a constant real number because we are dividing by a linear factor, x+5.

\frac{f(x)}{x+5}=Q(x)+\frac{R}{x+5}

Multiply both sides by (x+5):

f(x)=Q(x)(x+5)+R

Substitute x=-5:

f(-5)=Q(x)(-5+5)+17  (We were given R=17 since they did say the remainder is 17.)

f(-5)=Q(x)(0)+17

f(-5)=17

Answer:

  f(\boxed{-5})=\boxed{17}

Step-by-step explanation:

The remainder theorem tells you that f(a) is the result of division of f(x) by (x-a).

Here, you have f(x)/(x+5) = 17, so a=-5 and f(-5) = 17.

A guy-wire is attached to a pole for support. If the angle of elevation to the pole is 67° and the wire is attached to the groun
Andrews [41]
The angle = 67<span>° and the pole is a right-angled triangle. Therefore the distance required to find (say "x) is the angle opposite the right-angle. The following equation needs to be solved:

cos 67 = 137 / x

Solving for x;
x = 350.62 ft</span>
