<span>1/8(y−5)²=x+3
(y-5)² = 8(x+3)
The formula of parabola in standard form
(y-k)² = 4p(x-h), (h, k) - vertex, (h+p, k) focus
For our parabola
vertex (-3,5)
4p=8
p=2
This is a horizontal parabola because y².
So to find the coordinates of the focus we need to add to x coordinate of vertex.
</span>(-3+2, 5) = (-1,5) focus
Correct answer is (-1,5).<span>

The probability that he or she owns a credit card given that the student is a freshman is 0.63.
<h3>How to calculate the probability?</h3>
Number if freshman with credit card = 38
Total number of freshman = 60
Therefore, the probability that he or she owns a credit card given that the student is a freshman will be:
= 38/60
= 0.63
Therefore, the probability that he or she owns a credit card given that the student is a freshman is 0.63.

Answer:
y = logx/log8
Step-by-step explanation:
To find the inverse of an equation, you switch the locations of x and y, then solve for y.
So in this case, f(x) = y, and your equation is:
y = 8^x
It would become
x = 8^y
There are multiple ways to solve this- one I usually use is logs, so you take the log of both sides.
log x = ylog8
(when you take the log of something the exponent becomes a coefficient)
Then, y = logx/log8
