What is the slope of a line that is parallel to the line joining (7,-5) and (-5,7)
brilliants [131]

Answer:

Step-by-step explanation:

If two lines are parallel then they will have the same slope. So all you need to do is find the slope of the line that joins the two given points. You can use the slope formula \frac{y_2-y_1}{x_2-x_1}. You can also graph the two points and use rise over run. \frac{7-(-5)}{-5-7} =\frac{12}{-12}=-1

Let g be the piecewise defined function shown.
gogolik [260]
For this case we have the following function:
 g(x) =  \left \{ {{x+4} \atop {2-x}} \right.
 For each of the domains we will choose a value.
 We have then:

 For −5 ≤ x ≤ −1
 Let's choose the value of x = -3 
 Evaluating the function we have:
 g(x) = x+4

 g(-3) = -3+4

 g(-3) = 1
 Answer:
 
g(-3) = 1
 
 For −1 < x ≤ 5:
 
Let's choose the value of x = 0
 Evaluating the function we have:
 g(x) = 2-x&#10;&#10; g(0) = 2-0&#10;&#10; g(0) = 2
 Answer:
 
g(0) = 2

The rocket's height when the distance between you and the rocket is 100 feet is 98.9 feet

<h3>How to determine the rock's height?</h3>

The function is given as:

d = √216 +h²

At a distance of 100 feet, it means that:

d = 100

So, we have:

√216 +h² = 100

Take the square of both sides

216 +h² = 10000

Subtract 216 from both sides

h²= 9784

Take the square root of both sides

h = 98.9

Hence, the rocket's height when the distance between you and the rocket is 100 feet is 98.9 feet
