Answer:
i) The maximum height of the ball 'x' = 1.5 seconds
ii) The maximum height = 42
Step-by-step explanation:
<u>Step(i):</u>-
Given h(x) = - 16 x² + 48 x +6 ...(i)
Differentiating equation (i) with respective to 'x'
...(ii)
Equating Zero
- 3 2 x + 4 8 = 0
- 32 x = - 48
x = 1.5
<u><em>step(ii)</em></u>:-
The maximum height of the ball 'x' = 1.5
Again Differentiating equation (ii) with respective to 'x'

The maximum height 'x' = 1.5
h(x) = - 16 x² + 48 x +6
h(1.5) = - 16 (1.5)² +4 8 (1.5) +6
= 42
The maximum height at x = 1.5 is = 42
<u><em>Final answer</em></u>:-
i) The maximum height of the ball 'x' = 1.5 seconds
ii) The maximum height = 42
Answer:-21
Step-by-step explanation:
23+22=45
45-24=21
then flip 24 and 45 to get negative
Answer is
Point-slope form: y + 1 = 4(x -1)
Assuming you wanted
Slope-intercept form: y = 4x -5
Step by step
y - - 1 = 4(x -1)
y + 1 = 4(x -1)
y + 1 = 4x -4
y = 4x -5
