Answer:

A. Vertical Stretch

Step-by-step explanation:

Given function

y = 3x^2

Parent function is

f(x) = x^2

The given is

y = 3f(x) and it is the form of y = kf(x) with k > 1

Each point of y is 3 times closer to y-axis, therefore this is a vertical stretch.

Correct option is A only

Answer:

I'm pretty sure the Y position of the eyes is 70.

If the Variable Y is equal to 70, and the Y variable is where the Y axis value goes. Then the Y position of the eyes is equal to the Y variable which is 70. I think that makes sense, but feel free to comment if it does not so that I can help you figure it out.

Given that the sec A = 13/5 and A is in QIV, determine exact value for the sin A.

AysviL [449]

Answer:

The exact value of sin A is opp/hyp = -12/13

Step-by-step explanation:

If A is in Quadrant IV then the "opposite side" is negative and the "adjacent side" is positive. Since sec A = hyp / adj = 13 / 5 and since opp^2 + adj^2 must add up to hyp^2, Therefore y = √(hyp^2 - adj^2), or

y = -√(13^2 - 25) = -√144 = 12.

The exact value of sin A is opp/hyp = -12/13

...............what is (9x^2-3)^6

Lelu [443]

Step 1. Factor out the common term $3$

$(3(3 x^{2}-1)^{6}$

Step 2. Use Multiplication Distributive Property: $(xy)^{a} = x^{a} y^{a}$

 $3^{6}(3 x^{2}-1)^{6}$

Step 3. Simplify $3^{6}$ to $729$

$729(3 x^{2}-1)^{6}$

Done!
