Sum=14 + 37 + 22 + 56 + 33 = 152 => 100%
red = 14 => x%
100% / 152 = x / 14
x = 100 × 14 / 152
x = 1400 / 152
x = 9,21% = 9%
Answer:
1 seconds after being thrown, the stone reaches its max height
Step-by-step explanation:
The parabolic (quadratic) equation is:

Lets expand this in the form
, so we have:

We can say the values of a,b, and c, now to be:
a = -5
b = 10
c = 40
The number of seconds at which the max would occur is given by the point, x, at:

We know a and b, let's find the seconds, x,

Hence,
1 seconds after being thrown, the stone reach its max height
Answer:
The value of the angle x is 48°.
Step-by-step explanation:
Base of the triangle = 10
Height of the triangle = 11



The value of the angle x to the nearest degree is 48°.
