Answer:
t=6
Step-by-step explanation:
Answer: H
The first step is dividing 4 from both sides to find what m equals. By the way, its the <u>only</u> step :D
The answer is 27.1052631579 or 27.1 if you rounded "m" to .10
Answer:
15
Step-by-step explanation:
2.25 times 20=45
45-30=15
Let point P be with coordinates
Find the equation of the tangent line.
1. If
then 
2. The equation of the tangent line at point P is

Find x-intercept and y-intercept of this line:
- when x=0, then

- when y=0, then

The area of the triangle enclosed by the tangent line at P, the x-axis, and y-axis is

Since point P is on the parabola, then
and

Find the derivative A':

Equate this derivative to 0, then

And

Answer: two points:
