Answer:
D. -1/64
Step-by-step explanation:
F(x) = (1/4)^-3
This is 1/4 to the power of -3
= -(1/4)*(-1/4)*(-1/4)
= -(1*1*1)/(4*4*4)
= -1/64
Another way to calculate this is (-1/4)*(-1/4)*(-1/4). This is the same as (-1/4)³
When solved out the solution = -1/64
Therefore the correct answer to this question is the last option, which is d.
Thank you.
The graph is attached.
Answer:
(-2.2, 4) and (8.2, 4)
Step-by-step explanation:
In an ellipse, there is a minor radius and a major radius.
Let major radius be = a
Let minor radius be= b
From the graph, we are given:
Major radius, a = 6
Minor radius, b = 3
Now, let's find the distance from the center to the focus using the formula:

Substituting values, we have:



≈ 5.2
We can see from the graph that center coordinate is (3, 4). Therefore, the approximate locations of the foci of the ellipse would be:
(3-5.2, 4) and (3+5.2, 4)
= (-2.2, 4) and (8.2, 4)
Answer:
The correct answer is <u>D) -15, 15</u>
Step-by-step explanation:
(-)15^2 = 225
Therefore, x^2 = 225 = (-)15^2
