Y = a(x-0)^2 + 3
y = ax^2 + 3
plug in the point (-4,-45):-
-45 = (-4)^2 a + 3
-45 = 16a + 3
a = -48/16 = -3
answer is -3x^2 + 3
Answer:
(3 x 14) + 9

Answer:
- The next term of the sequence is represented by the point (5, –64)
Step-by-step explanation:
<u>Note:</u> <em>The first point should be (1, - 4)</em>
According to the points, the sequence is:
- t₁ = - 4, t₂ = 8, t₃ = - 16, t₄ = 32
or
We can observe it is a geometric sequence with common ratio of - 2, as:
- r = 32/ - 16 = - 16/8 = 8/ - 4 = - 2
The following term is:
- t₅ = t₄*r = 32*(- 2) = - 64
The coordinates of same term are:
As we see the correct answer choice is D.
Well first we have to find the area of the rectangle and the circle. Then we subtract the area of the circle from the rectangle. The area of the rectangle is length times width so 20*8.5=170. So the area of the rectangle is 170 cm^2 and now we have to find the area of the circle. To find the area of the circle, we have to find the radius and square it then multiply by pi. Based on the picture, we can tell that the diameter is 8.5 and the radius is half the diameter. So the radius is 4.25 and now we need to square it which is about 18.06. Now we take that and multiply by pi to get 56.71. Now we know that the area of the circle is 56.71 cm^2 so now we can subtract the area of the circle from the area of the rectangle. 170 - 56.71 = 113.29. Our answer is 113.29 cm^2. I hope this helps. Have a nice day!
