Okay. So the equation is 4x² - 16. We're talking about moving 7 units to the right and 3 units down. That formula would be h(x) = 4(x - 7)² - 19, because you would add -3 to the -16 units to get -19, and you would put the parenthesis around x and the 7 in order for it to move right. Keep in mind that parenthesis around x and a term means that we move either left or right, which didn't occur in the original equation. -16 is the amount of units down and adding -3 to it makes it -19. The answer is A.
Answer: D
Step-by-step explanation:
We're given a point (a,b) that happens to be on the unit circle, a²+b²=1, so a is the cosine of the angle θ and b is its sine.
<span>It is D: n(n+4). I solved it by a long, but easy method. First, I made up the value of N, the width, and made it 3. I then added 4 to 3, which is 7. So the length is 7 and the width is 3. The area of this made up rectangle is 21. The only answer choice that has 21 as the area is D.</span>
D D D D D D D !The answer to this question that you are trying to ask is d. say the sphere radius is one, if we did 4/3 of 1 cubed x 3.14, because the formula for volume is 4/3 pi R cubed, that would leave us with around 4.1., if you would take 1 times 2.5 cuz we're dilating, then you would have 4/3 of 2.5 cubed x 3.14. Now, the answer to that is around 10.46. Now, divide 10.46 bye 4.1. To get an answer of about 2.55, and remember were rounding, so if we did the exact math it would equal 2.5. so that would make it a, and I hope that you read this whole thing otherwise you just wasted all of those points...
