Graph the lines: y= 4x, y = – 4, and x = - 2.
Answers
I graphed the line, y = 4x, by using the y-intercept (0 ,0), and used the slope (m = 4) to plot other points: {(-1, -4), (1, 4)}.
For y = -4, it is a horizontal line (y = b) with a zero slope. Therefore, regardless of the x-value, its corresponding y-coordinate will be the same (y = -4). To graph the line for y = -4, start at y = -4 and create a horizontal line from there.
For x = -2, it is a vertical line (x = a) with an undefined slope. A vertical line has undefined slope because all points the line have the same x-coordinate. Thus, regardless of the y-value, its corresponding x-coordinate will always be x = -2. To graph the graph, I started at point (-2, 0), and created a vertical line from there.

When Jerome travels on the highway, he sets his cruise control at 65 mi/h. The function f(x)=65x represents his total distance f(x) when he has traveled x hours. How many miles will he have travelled after 3.5 hours of driving on the highway
Answers
The number of miles that he will have traveled after 3.5 hours of driving on the highway is 227.5 miles.
The function given to solve the question is: f(x) = 65x
where, x = number of hours
Therefore, when he travelled for 3.5 hours, the number of miles will be gotten by multiplying 65 by 3.5.
f(x) = 65x
= 65 × 3.5
= 227.5 miles.
Therefore, the number of miles that he will have travelled after 3.5 hours of driving on the highway is 227.5 miles.

List the possible outcomes for the members in the table. You can do this by keeping the first number constant and cycling through the remaining five numbers for the second (for example, 0-1, 0-2, 0-3 and so on). Then change the first number and repeat the process with the remaining five numbers. A point to keep in mind is that when the first lot is picked, the second will have one less number (the one you have picked) to choose from. For this reason, sequences such as 0-0, 1-1, and 2-2 cannot exist.

Nine times the sum of nine and a number is -25. What is the number
Answers
Answer:
9(9 + x) = -25
x = 6.22222 repeating
Step-by-step explanation:
First, we have to distribute. 9 times 9 = 81 and 9 times x = 9x. The equation now becomes 81 + 9x = -25.
Second, we have to get the coefficient alone. Since the opposite of positive 81 is negative 81, we subtract it to get 0. Since we did that to one side we have to do it to the other. -25 - (-81) = 56. Now we have 9x = 56.
Third, we have to get the variable by itself. To do that we divide 9 by 9 to get 0 and that gets the variable alone. Since we did that to one side we have to do it to the other. 56 divided by 9 = 6.222 with the 2 repeating over 8 times.

Question 1 A physician's “patient panel” is the list of all patients under their care. In the
US, the size of patient panels among primary care doctors is well modeled by a N(1500, 200)
distribution.
(a) If a "medium-sized” panel has anywhere from 1250 to 1750 patients, what proportion
of US primary care doctors have a patient panel that is NOT "medium-sized”?
(b) Find Q1,Q3 and the IQR of the patient panels of US primary care doctors.
Answers
Using the normal distribution, we have that:
a) The proportion of US primary care doctors have a patient panel that is NOT "medium-sized” is 0.2112.
b)
Q1 = 1365.
Q2 = 1635.
IQR = 270.
In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.For this problem, N(1500, 200) means that [tex]\mu = 1500, \sigma = 200[/tex].
Item a:
The proportion that are medium-sized is the p-value of Z when X = 1750 subtracted by the p-value of Z when X = 1250, thus:
X = 1750:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{1750 - 1500}{200}[/tex]
[tex]Z = 1.25[/tex]
[tex]Z = 1.25[/tex] has a p-value of 0.8944.
X = 1250:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{1250 - 1500}{200}[/tex]
[tex]Z = -1.25[/tex]
[tex]Z = -1.25[/tex] has a p-value of 0.1056.
0.8944 - 0.1056 = 0.7888 are medium.
1 - 0.7888 = 0.2112.
The proportion of US primary care doctors have a patient panel that is NOT "medium-sized” is 0.2112.
Item b:
Q1 is the first quartile, which is the 25th percentile, given by X when Z has a p-value of 0.25, so X when Z = -0.675. Then:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-0.675 = \frac{X - 1500}{200}[/tex]
[tex]X - 1500 = -0.675(200)[/tex]
[tex]X = 1365[/tex]
Thus, Q1 = 1365.
Q3 is the third quartile, which is the 75th percentile, given by X when Z has a p-value of 0.75, so X when Z = 0.675. Then:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]0.675 = \frac{X - 1500}{200}[/tex]
[tex]X - 1500 = 0.675(200)[/tex]
[tex]X = 1635[/tex]
Thus, Q3 = 1635.
The IQR is the difference between Q3 and Q1, that is:
[tex]IQR = Q3 - Q1 = 1635 - 1365 = 270[/tex]
Then, IQR = 270.

A charter fishing company buys a new boat for $224,000 and assumes that it will have a trade-in value of $115,200 after 16 years.
a. Find a linear model for the depreciated value V of the boat t years
after it was purchased.
b. What is the depreciated value of the boat after 10 years?
c. When will the depreciated value fall below $100,000?
d. Graph V for 0 ≤ t ≤ 30 and illustrate the answers from (b) and
(c) on the graph.
Answers
First, according to the information, we build a linear model, and then, the model is used to find the information asked.
a) The linear model is:
[tex]V(t) = 224000 - 6800t[/tex]
b) The depreciated value of the boat after 10 years is of $156,000.
c) The depreciated value falls below $100,000 after 18.24 years.
d) The sketch is given at the end of the answer.
Item a:
The initial value is of $224,000, thus, the y-intercept of the linear function is of [tex]b = 224000[/tex].The value decayed to $115,200 in 16 years, thus, the slope of the linear function is:[tex]m = \frac{115200 - 224000}{16} = -6800[/tex]
Then, the linear model is:
[tex]V(t) = 224000 - 6800t[/tex]
Item b:
The value after 10 years is V(10), so:
[tex]V(10) = 224000 - 6800(10) = 156000[/tex]
Then, the depreciated value of the boat after 10 years is of $156,000.
Item c:
This is t for which: V(t) = 100000. So
[tex]V(t) = 224000 - 6800t[/tex]
[tex]100000 = 224000 - 6800t[/tex]
[tex]6800t = 224000 - 100000[/tex]
[tex]6800t = 124000[/tex]
[tex]t = \frac{124000}{6800}[/tex]
[tex]t = 18.24[/tex]
The depreciated value falls below $100,000 after 18.24 years.

Answers
Width = x
Length = 4x - 9
A = L*W, so the equation is:
x(4x - 9) = 90
Solve:
4x^2 - 9x = 90
4x^2 - 9x - 90 = 0
(4x + 15)(x - 6) = 0
4x + 15 = 0
4x = - 15
x = -15/4
^^^ reject because distance can’t be negative
x - 6 = 0
x = 6 ft (width)
Length = 4x - 9
L = 4(6) - 9
L = 24 - 9
L = 15 ft
Check:
A = L*W
90 = 15 * 6
90 = 90
