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.
Step-by-step explanation:
Let the percentage be x%,
then,
x% of 80 = 64
He has ridden 80% of the total bike course.

Step 1) Distribute everything in parentheses by <em>8</em><em>.</em>
<em>16w-8-4w=-116</em>
Step 2) Combine like terms
<em>12w-8=-116</em>
Step 3) Add <em>8</em><em> </em>to both sides
<em>1</em><em>2</em><em>w</em><em>=</em><em>-</em><em>1</em><em>0</em><em>8</em>
Step 4) Divide
Answer: <em>-</em><em>9</em>
The result of division is 21.392
Rounded to the nearest tenth its 21.4 answer
(because the hundredth digit is 9 so you add 1 to the tenth digit.)
