Answer:
$11.25
Step-by-step explanation:
12/15=9/x
x=45/4
x=$11.25
Answer: C) 12.2
================================================
Explanation:
We have a known adjacent side (10) and an unknown hypotenuse (x). The cosine rule ties the two sides together.
cos(angle) = adjacent/hypotenuse
cos(35) = 10/x
x*cos(35) = 10
x = 10/cos(35)
x = 12.2077458876146 approximately
x = 12.2
Make sure your calculator is in degree mode.

Answer: B
<u>Step-by-step explanation:</u>
The parent graph is y = x²
The new graph y = -x² + 3 should have the following:
- reflection over the x-axis
- vertical shift up 3 units
Answers:
- a. Quadrant II
- b. negative
- c.

- d. C
- e.

<u>Explanation:</u>

a) Quadrant 2 is: 
b) In Quadrant 2, cos is negative and sin is positive, so tan is negative
c)
= 
d) the reference line is above the x-axis so it is negative --> 
e)
