Answer:
D) 360
Step-by-step explanation:
The data Kyle collected is (0, 0), (1, 12), and (2, 24), where x represents days and y represents likes.
We can write a linear function to model this situation.
This will be of the form
because it passes through the origin , where m is the slope.
The slope is
Hence the equation is
To find the number of likes on the 30th day, we put x=30 into the equation to get:
The correct choice is D
Answer:
Step-by-step explanation:
you know the total angle is 180° from A to D
and you know that ∠BEC is 90°
also you are told that ∠CED is 18°
and that ∠AEB is 4x°
so just put that all together
180=90 + 18 +4x
now solve for X
180-90-18=4x
72=4x
18 = x
so now you know X
now solve ∠AEB
4(18) = 72°
∠AEB= 72°

Answer:
1. Option A
2. Option B
Step-by-step explanation:
I would like to elaborate on the answer to the second question, since the first answer is actually option a. Why? The question asks for a parametric equation, not set, so it would be choice a.
2. x=3t + 5 - isolate t
t=(x-5)/3 - substitute into the second equation
y = [(x-5)/3]^2 - 1
your solution is option b

Answer: c. 8(y-6) = (x-2)^2</h3>
Explanation:
The directrix is horizontal, so the axis of symmetry is vertical. We'll have an x^2 term. The vertical distance from y = 4 to y = 8 is 4 units. Cut this in half to get 2, which is the focal distance p = 2.
The point (2,4) is directly below (2,8), and the point is on the directrix. The midpoint between (2,4) and (2,8) is (2,6). This is the vertex.
(h,k) = (2,6)
4p(y-k) = (x-h)^2
4*2(y-6) = (x-2)^2
8(y-6) = (x-2)^2
