Answer:
Function 1 written in vertex form is f(x) = -x^2 + 8x - 15 = -(x^2 - 8x + 15) = -(x^2 - 8x + 16 + 15 - 16) = -(x - 4)^2 - (-1) = -(x - 4)^2 + 1
Therefore, vertex = (4, 1)
Function 2 written in vertex form is f(x) = -x^2 + 4x + 1 = -(x^2 - 4x - 1) = -(x^2 - 4x + 4 - 1 - 4) = -(x - 2)^2 - (-5) = -(x - 2)^2 + 5
Therefore vertex = (2, 5)
Function 1 has a maximum at y = 1 and function 2 has a maximum at y = 5. Therefore, function 2 has a larger maximum.

Answer:
1 3/4 hours
Step-by-step explanation:
There are 7 days in a week, so we will multiply by 7 days
7 * 1/4 = 7/4 hours
Changing this to a mixed number
1 3/4 hours
Answer:
Well it is 16
Step-by-step explanation:
the rectangle has 2 of the same sides for each side, so 3x2+5x2, a square has all sides equal to each other, so 4x4
So Now we do the easy part|
The rectangle that is grey:
3x2 = 6
5x2 = 10
6+10 =16
The orange square:
4x4 = 16
4+4=8
4+4=8
8+8=16
Therefore both are 16, meaning 16 must be the perimeter for both!

Answer:
The probability is 1/8 or 0.125.
Step-by-step explanation:
Given is that three fair coins are flipped.
And we have to find the probability of getting a head on the first flip,a tail on the second flip, and another head on the third flip.
Firstly, here each flip is independent of the outcome of the other flips.
So, the probability of head is 1/2 and the probability of tail is 1/2.
Therefore, the answer will be : (1/2) (1/2) (1/2)=8
