first look at the equation you’re given. It’s in y-intercept form. The slope is 5.
A line perpendicular to it has a slope that is the opposite reciprocal, -1/5. You are told that the y-intercept of the line is 4, so the equation for the Since the slope of the line is -1/5, and the y-intercept is 4, the equation of the line is,
y = (-1/5)x + 4
Multiply both sides by 5 and put into standard form,
x + 5y = 20line in y-intercept form is y= -1/5x+4
When we have a linear equation in standard form, we can find the x- and y-intercepts of the corresponding line. This also allows us to graph it.

Mohammad leaves home walks 5 blocks to the library. he then walks 2 blocks toward home to meet up with his friend. together, he and his friend walk to the library together. how far did mohammad walk?
If Mohammad leaves home walks 5 blocks to the library and he then walks 2 blocks toward home to meet up with his friend and then together, he and his friend walk to the library together, then Mohammad walked for 9 blocks.
To calculate how far Mohammad walked we use addition.
Total blocks Mohammad walked = blocks to the library + blocks towards home to meet up with friend + blocks back to the library together
blocks to the library = 5
blocks towards the home to meet up with friend = 2
blocks back to the library together = 2 (As he walked 2 blocks towards home from the library, he will walk the same number of blocks again to reach the library)
Therefore,
total blocks Mohammad walked = 5 + 2 + 2
total blocks Mohammad walked = 9
Hence, the number of blocks Mohammad walked for is calculated to be 9.

Step-by-step explanation:
36. Where's the bus? Sally takes the same bus to work every morning. The amount of
time (in minutes) that she has to wait for the bus to arrive is described by the
uniform distribution below.
0
10

Height =
10
(a) Explain why this curve satisfies the two requirements for a density curve.
(b) On what percent of days does Sally have to wait more than 8 minutes for
the bus?
(c) On what percent of days does Sally wait between 2.5 and 5.3 minutes for
the bus?
According to the question, every morning Sally takes same bus and she has to wait to arrive with the used method called as uniform distribution.
And the range of the interval is as: min = 0 and max = 10.
For the calculation of the uniform distribution, the height some be constant.
Now, using standard uniform distribution formula:
Mathematically, the function f(x) can be written as:
f(x) = 1/(b - a)
where, 'a' and 'b' are defined intervals. Here, a = 0; b = 10.
Now, to calculate the percentage form the area as a rectangular grid which means:
f(x) = 1/10(5.3 - 2.5) = 2.8/10 = 0.28 = 28 percent.
Now, to know the percentile using above data:
f(x) = 1/(b - a) = 7/10 = 0.7 = 70 percent.
What is uniform distribution?
The uniform distribution is also called as density function which the nature of the two or more than two function should be equal or same.

For each rational function, find any points of discontinuity.
y=2x-1 / x²+4
In rational functions, the discontinuities are caused by the denominator terms. Since the denominator of a fraction is non-zero, any term multiplied by the denominator is also non-zero.
To find the discontinuities, we need to factor the polynomial below. Once we have the two binomials, we set each to 0. This way, you can find the value that produces 0 in the denominator.
If x = -2 then (x^2) + 4 is 0.
So, the discontinuities are shown as x = -2

Solve the equation x²+10 x+40=5 by completing the square.
So we are provided with the equation,
x2 + 10x + 40 = 5
To simplify it, we will first reorder the terms,
40 + 10x + x2 = 5
Now we will solve the equation to find the value of the unknown variable that we declared here as x.
40 + 10x + x2 = 5
Solving for variable 'x.'
40 + -5 + 10x + x2 = 5 + -5
We will combine similar terms; the variables and the constants.
40 + -5 = 35
35 + 10x + x2 = 5 + -5
Combine the like terms again:
5 + -5 = 0
35 + 10x + x2 = 0
Adding -35 on both sides
35 + 10x + -35 + x2 = 0 + -35
35 + -35 + 10x + x2 = 0 + -35
35 + -35 = 0
0 + 10x + x2 = 0 + -35
10x + x2 = 0 + -35
0 + -35 = -35
10x + x2 = -35
The x term is 10x.
Take half its coefficient (5) to make it a perfect square.
Square it (25) and add it to both sides.
10x + 25 + x2 = -35 + 25
25 + 10x + x2 = -35 + 25
-35 + 25 = -10
25 + 10x + x2 = -10
Perfect square on the left side:
(x + 5) (x + 5) = -10
We can see that the Square root of the right side can’t be calculated.

Rita had r apps (let r = Rita original apps)She deleted 5 of them so r-5 She now has twice the number of apps as Cora so r-5 = 2c (let c = Cora's total apps) Cora's total apps are 36 so Rita's equation is r-5= 2(36) which means Rita equation for her number of apps is r-5= 72.

Determine if each function is a vertical stretch or vertical compression of the parent function y=|x| .
y= 3/2|x|
Vertically Stretching and Compressing
Multiplying a function by positive constant yields a function whose graph is vertically stretched or compressed relative to the original function's graph. If the constant is greater than 1, it will stretch vertically. If the constant is between 0 and 1, vertical compression is done. You get vertical compression.
Vertical compression occurs when you multiply the function by a rational scaling factor. The base of the function graph remains the same even when the graph is compressed vertically. Only initial values are affected.

d. What is the ratio of the volumes of Spaceship Earth to a golf ball?
The ratio of the volumes of the Spaceship Earth to a golf ball = 1926949795 : 1
We need to find the volumes of the Spaceship Earth and a golf ball.
Spaceship Earth
Radius, R = 165/2 ft = 82.5 ft
Volume of the Spaceship Earth = [tex]\frac{4\pi R^3}{3}[/tex] = (4 x 3.14 x 561515.625)/3
= 2350878.75 cubic ft.
A golf ball
Radius = 1.5/2 inches = 0.75 inches
1 ft = 12 inches
So 0.75 inches = 0.75/12 = 0.0625 ft.
So radius, r = 0.0625 ft
Volume of a golf ball = [tex]\frac{4\pi r^3}{3}[/tex] = (4 x 3.14 x [tex]0.0625^3[/tex])/3

A student walked 100 meters north, then 100 meters west. How many more meters did the student walk compared to their total displacement from their starting point?.
Using Pythagorean theorem, the student walked 53.58 meters more compared to the total displacement from the starting point.
If a student walks 100 meters north, then 100 meters west, then the path he travels resembles the sides of a right triangle (see attached photo).
Using Pythagorean theorem, we can solve for the total displacement from the starting point to the end point.
c^2 = a^2 + b^2
where c is the total displacement from the starting point to the end point
a is the distance he walks up north
b is the distance he walks to the west
c^2 = 100^2 + 100^2
c^2 = 10,000 + 10,000
c^2 = 20,000
c = 141.42 meters
