You have

$(f\circ g)(x) = f(g(x)) \implies (f\circ g)(7) = f(g(7))$

So, we have to compute g(7) and feed it as input to f(x). We have

$g(7)=7-6=1 \implies f(g(7))=f(1)=-5-1=-6$

What is the equation of the line that contains point(3, -2) and has a slope of 5?

Olenka [21]

Answer:

y = 5x - 17

Step-by-step explanation:

y = mx + c

m = the gradient/slope = 5

y = 5x + c

Substitute (3, -2) into the equation above to find c.

-2 = 5(3) + c

-2 = 15 + c

-2 - 15 = c

-17 = c

y = 5x - 17

An 85-foot rope from the top of a tree house to the ground forms a 45 degree angle of elevation from the ground. How high is the

Feliz [49]

Answer:

$\boxed{h=60.1\ ft }$

Step-by-step explanation:

<u>Right Triangles </u>

They have a right angle (90°) and a longer side called the hypotenuse opposite to the right angle. The legs and the hyponetuse form two angles that must sum 90°, and they comply:

$\displaystyle sin\ \alpha=\frac {opp-leg}{hypotenuse}$

Where opp-leg is the opposite leg to $\alpha.$

The rope from the top of a tree house is 85-foot long. It's the hypotenuse (L) of the triangle it forms with the ground and the tree. The angle of 45° is opposite to the height of the tree (h).

$\displaystyle sin\ \alpha=\frac {h}{L}$
