Answer:

Step-by-step explanation:

We want to find the composite function at a specific value (-5).

Thus, we can write and think of the function like this:

f[g(-5)]

So we substitue the -5 for every x in the g(x) function:

g(x) = -5 + 7 = 2

Then we substitute this 2 for every x in the f(x) function:

f(x) = 2^2+7(2) = 4 + 14 = 18

Determined the quadrant for an angle with the following characteristics: cotθ>0 and cscθ>0.

oee [108]

$\csc\theta=\dfrac1{\sin\theta}>0\implies\sin\theta>0$

This happens whenever the terminal point of $\theta$ lies in either the first or second quadrants.

Meanwhile,

$\cot\theta=\dfrac1{\tan\theta}=\dfrac{\cos\theta}{\sin\theta}>0\implies\cos\theta>0$

since you already know sine is positive. Cosine is positive when the angle lies in the first or fourth quadrant.

Sine and cosine are both positive only when $\theta$ is the first quadrant, which means this angle's terminal point lies in the first quadrant (A).

In the figure below, mZAHE = (6x + 7)º

Andru [333]

Answer:

Step-by-step explanation:

∠AHE + ∠AHK = 180 {linear pair}

6x + 7 + 35 = 180

6x + 42 = 180

6x = 180 - 42

6x = 138

x = 138/6

x = 23
