Describe the slope of the line
Find the slope
Answers
Answer:
Question one: Zero slope
Question two: [tex]m=\frac{0}{4}[/tex]
Step-by-step explanation:
Given the following questions:
Question one:
The following line is what you call a "zero slope." Zero slopes are lines that are neither decreasing or increasing and remain at a constant or just a straight line.
Question two:
Point A = (-2, -3) = (x1, y1)
Point B = (2, -3) = (x2, y2)
Using the formula for slope or rise over run we will solve and find the slope of this line.
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
[tex]m=\frac{-3--3}{2--2} =\frac{0}{4}[/tex]
[tex]m=\frac{0}{4}[/tex]
The slope of this line is "0/4."

Given a quadratic function in vertex form:
f(x) = a(x - h) 2+ k
a. For what values of a does a VERTICAL STRETCH take place?
b. For what values of a does a VERTICAL COMPRESSION take
place?
c. How does a VERTICAL STRETCH compare to a HORIZONTAL
COMPRESSION?
d. For what values of a does a REFLECTION across the x-axis take
place?
Answers
Answer:
See below
Step-by-step explanation:
Part A
A vertical stretch takes place when [tex]a\cdot f(x)[/tex] given that [tex]|a| > 1[/tex]
Part B
A vertical compression takes place when [tex]a\cdot f(x)[/tex] given that [tex]0 < |a| < 1[/tex]
Part C
A vertical stretch is different than a horizontal compression:
In a vertical stretch, the input stays the same, but the output is multiplied by the scale factorIn a horizontal compression, the output stays the same, but the input is multiplied by the scale factorPart D
A reflection across the x-axis means that the output, our y-variable, is the opposite sign. This means that all values of [tex]a[/tex] must be negative such that [tex]a\cdot f(x)[/tex] as mentioned in parts A and B. Also, in part C, since our scale factor is negative, the output is the only one being multiplied by the scale factor.
The answer to all parts is given below.
Define equation? What is quadratic equation?Equation is defined as a relation that equates two expressions. A quadratic equation is of the form -
ax² + bx + c = 0.
Given is quadratic function in vertex form:
f(x) = a(x - h)² + k
Let's assume the equation as -
f(x) = a(x - 3)² + 5
Refer to the graph attached.
[A] -
As [a] → ∞, the vertical stretch takes place.
[B] -
As [a] → 0, the vertical compression takes place.
[C] -
As [a] → ∞, both the vertical stretch and horizontal compression takes place.
[D] -
for [a] < 0, a reflection across the x-axis takes place
Therefore, the answer to all parts is given above.

The perimeter of a square is twenty-eight
inches. What is the length of each side?
Answers
The perimeter of any shape is given by the sum of it's all sides and as here the shape is square so it's all sides must be equal and it have 4 sides. So if we assume it's one side to be s , then perimeter = (s+s+s+s) = 4s , so in our question :

[tex]{:\implies \quad \sf s=\dfrac{28}{4}=7}[/tex]

A contractor has estimated that the minimum number of days to remodel a bathroom for a client is 10 days. He also estimates that 80% of similar jobs are completed within 18 days. If the remodeling time is uniformly distributed, what should be the parameters of the uniform distribution
Answers
The parameters for the uniform distribution should be of a = 10 and b = 20.
What is the uniform probability distribution?It is a distribution with two bounds, a and b, in which each outcome is equally as likely.
The probability of finding a value of at lower than x is:
[tex]P(X < x) = \frac{x - a}{b - a}[/tex]
In this problem, a contractor has estimated that the minimum number of days to remodel a bathroom for a client is 10 days, hence the lower bound is of a = 10.
He also estimates that 80% of similar jobs are completed within 18 days, hene P(X < 18) = 0.8, thus the upper bound is given by:
[tex]P(X < x) = \frac{x - a}{b - a}[/tex]
[tex]0.8 = \frac{18 - 10}{b - 10}[/tex]
[tex]0.8b - 8 = 8[/tex]
[tex]0.8b = 16[/tex]
[tex]b = \frac{16}{0.8}[/tex]
[tex]b = 20[/tex]

start by canceling 4x on both sides.
x − 5 − 4 = 8 − 5x + 7
simplify x − 5 − 4 to x - 9
x - 9 = 8 - 5x + 7
simplify 8 - 5x + 7 to -5x + 15
x - 9 = -5x + 15
add 9 to both sides
x = -5x + 15 + 9
simplify -5x + 15 +9 to -5x + 24
x = -5x +24
add 5x to both sides
x + 5x = 24
simplify x + 5x to 6x
6x = 24
divide both sides by 6
x = [tex]\frac{24}{6}[/tex]

when a kitten is born it weighs 1.5 pounds. after 3 weeks it weighs 3 pounds. when the kitten is 6 weeks old it weighs 7.5 pounds. what percent weight gain did the kitten grow over from the first weight?
Answers
Answer:
It grew by 500% meaning it grew on average 83.333% per week
Step-by-step explanation:
To find the percent growth you divide the end weight by the starting weight:
[tex]7.5/1.5=5[/tex]
However, that is the percentage in decimal form. To convert that number to a percentage move the decimal place to the right 2 places. This results in 500%
To get the average weekly growth weight, simply divide the 500% by the amount of weeks (6). This then gives the 83.333% per week.
Note: I didn't know which answer you were looking for. That is why there are 2.
