the axis of symmetry is x=2
Answer:
Choice D
Step-by-step explanation:
You use the formula V=pi(radius^2)(h). Once you take the pi out and plug in the numbers, you should get V= 6^2(9). You get 324 with the pi added on after it.
The answer to this problem is C.
Here's why:
The area of a triangle = 1/2 * (base) * (height) (Note: a triangle is half of a rectangle, and rectangles have Area = (base) * (height))
<span>Because the base of ΔAED is half of ΔACB (2 = (1/2) * 4), and height of ΔAED is half of ΔACB (3 = (1/2) * 6), we know that the area of ΔAED will be half of ΔAED.

So, it's C. I am sure =)

9 the smallest angle is always opposite the smallest side
Answer: choice d, angle B
They couldn't match the choice letters with the angles? Geez.
10. That's an isoscles triangle
d + d + 116 = 180
2d = 64
d=32
choice a
11. 62+45+k=180
k=180-107 = 73
choice b
Answer:
The answer is $19.44
Step-by-step explanation:
First you have to find 25% of $28.80 (which is 7.20). Then, you subtract the $7.20 from your 28.80. You do that because you are getting a 25% discount. Then, you find 10% of $21.60 (your answer for the 25% discount) and you subtract 10% of $21.60. After that, you get your total of $19.44.
I hope you find this helpful.
