Answer:
x = 2
Step-by-step explanation:
H(x) = 64x - 16x²
<u>Find the value of x when the ball reaches its maximum height.</u>
<u />
Since the largest degree in this equation is two, this function represents a parabola. We can find the maximum height of the ball at the vertex of the quadratic.
In H(x) = 64x - 16x², rearrange the powers from greatest to least:
Vertex: [-b/2a, f(-b/2a)]
Substitute a and b into the x-value of the vertex: -b/2a.
The vertex of the parabola is at x = 2, with a maximum height of H(2).
Answer :36 explanation: (39x39)-(15-15)=1296 then square root that and get 36
Assuming you meant 6x198 do a mental sum for 6x200 (1200) then subtract 6x2(12)to give you 1188
The area of the new square is 7^2 = 49.
The area of the old square is 4^2 = 16.
Hence, the new square is 33 greater than the old one.
The mean temperature is 20 degrees celsius
