Answer:
The answer is 3.12
Step-by-step explanation:
Answer:
see the explanation
Step-by-step explanation:
we have the quadratic equation

This is a vertical parabola open downward
The vertex is a maximum
Find the x-intercepts of the quadratic equation
The x-intercepts are the values of x when the value of y is equal to zero
so
For y=0

Solve the quadratic equation
The formula to solve a quadratic equation of the form
is equal to

in this problem we have
so

substitute in the formula





therefore
This parabola has two x-intercepts representing the times when the dolphin's height above water is zero feet

Answer:
f(g(-7))
Step-by-step explanation:
Answer:
a=22.6549
Step-by-step explanation:
Calculated based on 2 given angles and 1 given side.
∠C = 180° - A - B = 0.99484 rad = 57°
a = c·sin(A)/sin(C) = 22.6549
b = c·sin(B)/sin(C) = 12.33874
