The vertex is at (2, 5).
To find the vertex, we first find the axis of symmetry; this is given by
x = -b/2a
For our equation, b = -16 and a = 4:
x = -(-16)/2(4) = 16/8 = 2
We substitute this back into our equation:
y = 4(2)² - 16(2) + 21 = 4(4) - 32 + 21 = 5
Therefore the vertex is at (2, 5).
I don't know if I did this right.
There are 1097.6 pages in the book. I multiplied .35 by 56 and got 19.6. I multiplied 19.6 by 56 and got 1097.6. Therefore, there are 1097.6 pages in the book.
When x = -2, g(-2) = 4
and
when x = -2, f(-) = 4
answer
f(-2) = g(-2)
Answer:
the answer that 3.45 should be as a percent should be 345% because you mutliply 3.45 times 100 getting an answer of 345% and if you want to convert into a mixed number the percent 3 45/100 or simplified to 3 9/20 so hopefully that is the correct answer.
Step-by-step explanation: :DDDDDD hope this helps and mark me brainliest please.
