Answer:

(x-7, y-5)

Step-by-step explanation:

To describe a translation, track its movement of one point from its pre-image to image since all points move the same direction and distance.

Point I starts at (-3,2). Point I' ends at (-10,-3). This means that x went from -3-->-10 which is -7. So we write x-7 or x+-7. The y coordinate went from 2-->-3 which is -5. So we write y-5 or y+-5.

Put it together into an (x,y) point as (x-7, y-5) or (x+-7, y+-5).

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.

Simplify the rational expression -27x^2y/9xy

zepelin [54]

This is much easier to explain with a picture so...
First, simplify the coefficients. Then, simplify the variables. The y's cancel each other out so, you have your answer of -3x
