Answer:
19 points
Step-by-step explanation:
convert points to percents:
20 points = 100%
19 points = 95%
18 points = 90%
17 points = 85%
percent-wise, her average prior to another quiz is 92.5
so if she wants to keep to maintain that average she must get 18 1/2 points; if teacher doesn't award partial credit then she needs to get a full 19 points
Answer:
the answer is 81,592 cuz you have to multiple
Answer: (6,-20)
Explanation:
The equation f(x) = -(x-6)^2 - 20 is the same as y = -1(x-6)^2 + (-20)
It is in the form y = a(x-h)^2 + k
The vertex is (h,k)
In this case, h = 6 and k = -20
So that's why the vertex is (6,-20)
