I'll do the first two to get you started

===============================================

Problem 1

A = 3 = starting value

B = 10 = ending value

C = percent change

C = [ (B - A)/A ] * 100%

C = [ (10-3)/3 ] * 100%

C = (7/3) * 100%

C = 2.3333333 * 100%

C = 233.33333%

C = 233.3%

The positive C value means we have a percent increase. If C was negative, then we'd have a percent decrease.

<h3>Answer: 233.3% increase</h3>

===============================================

Problem 2

A = 9 = start value

B = 20 = end value

C = percent change

C = [ (B - A)/A ] * 100%

C = [ (20-9)/9 ] * 100%

C = (11/9)*100%

C = 1.2222222222*100%

C = 122.22222222%

C = 122.2%

<h3>Answer: 122.2% increase</h3>

The path of a baseball, hit 3 feet above ground, is modeled by the function f(x)=-0.01x^2+x+3, where f(x) represents the vertica

Answer:

Therefore the ball travel 102.92 feet horizontally before hitting the ground

Step-by-step explanation:

Given that, the path of a baseball, hit 3 feet above ground, is modeled by the function

$f(x)=-0.01 x^2+x+3$

where f(x) represents the vertical height of the ball in feet(Assume) and x is the horizontal distance in feet(Assume) .

When the ball hits the ground, then the vertically distance of the ball will be zero, i.e f(x)=0

$\therefore -0.01 x^2+x+3=0$

[Applying quadratic formula $x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$ , here a = -0.001, b=1 and c=3]

$\Rightarrow x=\frac{-1\pm\sqrt{1^2-4.(-0.01).3}}{2.(-0.01)}$

$\Rightarrow x=-2.94, 102.92$

Therefore the ball travel 102.92 feet horizontally before hitting the ground.
