Option B: 1.6 s.
Although the equation is not included, you can obtain it by physical considerations
H(t) = -16.t^2 + 52t + 16
The maximum point is at the vertex and the vertex is in the middle of the roots.
The roots are when H(t) = 0,
So you have to solve 0 =-16t^2 + 52t + 16
Use the quadratic formula and you will find t = 3.53 and t =-0.28
Then the vertex is at the middle point = (3.53 -.028)/2 =1.63 s and the answer is option B: 1.6 s.
Answer:
The value of x is 2.11
Step-by-step explanation:
area of a triangle=95m^2
perpendicular(p)=3x
base(b)=3x
now,
area of right angled triangle=1/2*b*p
or,95=1/2*3x*3x
or,95*2=9x
or,190=9x
or,190/9=x
x=21.11
