Answer:
36
Step-by-step explanation:
The maximum height is the y-coordinate of the vertex
given a quadratic in standard form : ax² + bx + c : a ≠ 0
then the x-coordinate of the vertex is
= - 
y = - x² + 20x - 64 is in standard form
with a = - 1, b = 20 and c = - 64, hence
= -
= 10
substitute x = 10 into the equation for y
y = - (10)² + 20(10) - 64 = 36 ← max height
Answer:
930
Step-by-step explanation:
600% of x = 5580
6x = 5580
x = 5580/6
x = 930
Answer:
25n^8
Step-by-step explanation:
Area of a square is length×length
Length=5n^4
Area=5n^4×5n^4
=(5×5)(n^4+4)
=(25)(n^8)
=25n^8
So the area of a square is 25n^8
The square root of 5,000 is 70.7106781187.
Answer:the value where the line crosses the y axis
Step-by-step explanation:
its crossing through the y-axis not the x-axis because. The y-intercept is where the line crosses the y-axis. for example, you see the line cuts across the y-axis at -2. This makes our y-intercept -2.
