You need to first add total amount of students (8+10+6+3+3). Then add amount of students who got a grade of C and above (8+10+6). The total amount of students is your denominator and the amount who earned at least a C is your numerator. You then need to simplify your fraction.

A ball is thrown into the air with an upward velocity of 36 ft/s. Its height h in feet after t seconds is given by the function
Aloiza [94]

The ball's maximum height is 30.25 feet.

<h3>What is quadratic equation?</h3>

A quadratic equation in math is a second-degree equation of the form ax² + bx + c = 0. Here a, b, are the coefficients, c is the constant term, and x is the variable.

Given:

h= -16t²+36t+10

Differentiate w.r.t. 't',

h' = -32t+36

When h=0, that will be the maximum height

32t= 36

t= 9/8

t= 1.125 sec.

So, The maximum height is

h(1.123)= -16(1.125)² + 36*1.125+10

h(1.125) = 30.25 feet.

Solve for x. Round to the nearest tenth of a degree, if necessary.
kakasveta [241]

Answer:

x ≈ 52.1°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan x = \frac{opposite}{adjacent} = \frac{KL}{LM} = \frac{36}{28} , then

x = tan^{-1} (\frac{36}{28} ) ≈ 52.1° () to the nearest tenth )
