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?
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 Value of Y is 3 MORE than X.
For example, Because the equation is x+3=y
x is any number on the top row,
y is any number on the bottom row,
Meaning 1 + 3 = 4 Because 1 is on the x row, and 4 is on the y row.
You find the number you want to try and do x+3=y

Describe the slope of the line
Find the slope
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."

Find the volume of the sphere
Answer:
Formula: [tex]\frac{4}{3}\pi r^3[/tex]
Plug in values: radius = 9.3
Volume: 1072.476π cubic units
Step-by-step explanation:
The formula to find the volume of a sphere is [tex]\frac{4}{3}\pi r^3[/tex], where r = radius. In this case, we leave the volume of sphere in terms of pi.
The only value we can plug in is the radius. In this case, the radius is 9.3 units.Now, we can solve for the volume:
[tex]\frac{4}{3} *9.3^3 * \pi[/tex] [tex]\frac{4}{3} * 804.357 * \pi[/tex] [tex]1072.476 * \pi[/tex] [tex]1072.476\pi[/tex]Suppose that I wrote 150 words of my English paper yesterday and today I begin typing at a rate of 35 words per minute. Is the total number of words typed a linear function of the number of minutes since I began typing today?
Explanation:
x = number of minutes
35x = number of extra words after x minutes
This is because you add on 35 words per minute (wpm). So for instance, after 10 minutes, you add on 35x = 35*10 = 350 more words.
This is on top of the initial 150 words you already wrote yesterday. So we add the 35x onto the 150 to get the expression 35x+150. This represents the number of words total from yesterday and today combined.
Saying y = 35x+150 shows we have a linear function of the form y = mx+b
m = 35 = slope
b = 150 = y intercept

Expand the logarithm as much as possible. Rewrite the expression as a sum, difference, or product of logs.
ln(1/4k)
Enclose arguments of functions in parentheses and include a multiplication sign between terms. For example, c*ln(h).
ln(1/4k)=
Step-by-step explanation:
[tex] ln( \frac{1}{4}k ) [/tex]
[tex] ln(k {}^{ - 2} ) [/tex]
[tex] - 2 ln(k) [/tex]
The simplified form of logarithm is [tex]ln(\frac{1}{4k}) = - ln(k) - 2ln(2)[/tex]
What is Logarithm?
The power to which a number must be increased in order to obtain another number is known as the Logarithm. A power is the opposite of a logarithm. In other words, if we subtract an exponentiation from a number by taking its logarithm
The properties of Logarithm are :
log A + log B = log ABlog A − log B = log A/Blog Aⁿ = n log AGiven data ,
The equation is
[tex]A = ln(\frac{1}{4k})[/tex]
Now , from the logarithm rule log A − log B = log A/B , we can simplify
[tex]ln(\frac{1}{4k}) = ln(1) - ln (4k)[/tex]
And , [tex]ln(1) = 0[/tex]
So ,
[tex]ln(\frac{1}{4k}) = - ln (4k)[/tex]
Now , from the logarithm rule log A + log B = log AB , we get
[tex]ln(\frac{1}{4k}) = - ( ln(k) + ln(4) )[/tex]
[tex]ln(\frac{1}{4k}) = - ln(k) - ln(4)[/tex]
And , [tex]ln(4) = 2 ln(2)[/tex]
So ,
[tex]ln(\frac{1}{4k}) = - ln(k) - 2ln(2)[/tex]
Hence , the simplified form of logarithm is [tex]ln(\frac{1}{4k}) = - ln(k) - 2ln(2)[/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
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]
