Answer:
Perimeter = 15 cm
Step-by-step explanation:
The equation P=5s represents the perimeter P of a regular pentagon with side length s.
We need to find the perimeter of a regular pentagon with side length of 3 cm.
To find it, put s = 3 cm in the given equation.
P = 5(3) cm
= 15 cm
Hence, the perimeter of the regular pentagon of side length 3 cm is 15 cm.
Answer:
ABC = 60
BCA = 90
CAB = 30
Step-by-step explanation:
5x+9x+6+90 = 180
5x+9x = 84
14x = 84
x = 6
5x = 30
9x+6 = 60
Pi = 3.141593
Radius = half diameter
Calculate Circumference = 2 pi r (2*pi*radius)
Calculate Time = Circumference / Speed
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
