Please answer #11,#15,and #16.For #11, determine if the graph represents a function.For #15-16 find the domain and range of the function represented by the graph.
Answers
Problem 11
Answer: Not a function
Why not? Because it fails the vertical line test. It is possible to draw a single straight vertical line through more than one point on this blue curve.
Put another way: An input like x = 2 produces more than one output (y = 2 and y = 4 at the same time). If we wanted a function, we need any given input in the domain to produce exactly one and only one output.
=============================================================
Problem 15
Answers:
Domain: [tex]-4 \le x \le 2[/tex]Range: [tex]2 \le y \le 6[/tex]Explanation:
The domain is the set of allowed x values. The left-most point on the blue curve is when x = -4, which is the smallest item allowed in the domain. The largest value allowed is x = 2, as this occurs at the right-most point on the blue curve. Therefore, our domain here is [tex]-4 \le x \le 2[/tex]
The range is similar, but we focus on y values this time. The lowest the graph goes is y = 2, and the highest it goes is y = 6. So [tex]2 \le y \le 6[/tex] represents the range of possible y outputs.
For both the domain and range, both endpoints are included.
=============================================================
Problem 16
Answers:
Domain: [tex]2 < x < 7[/tex]Range: [tex]1 < y < 6[/tex]Explanation:
We follow the same idea as before. This time however, we have open holes which means that we do not include the endpoints.
The domain is [tex]2 < x < 7[/tex] since the curve spans from x = 2 to x = 7, excluding both of those x values. The range is [tex]1 < y < 6[/tex] for similar reasoning.
Notice how both problems 15 and 16 are functions because they pass the vertical line test. It is not possible to draw a single vertical line through more than one point on either blue curve.

pair of pants, which will have 4% sales tax.
a.) What is the inequality that represents the amount of money you have to spend?
b.) Given that you can spend no more than $60, what is the most a pair of pants could cost?
Answers
Answer:
a. pants + tax + drink ≤ 60 b. $56.16
Step-by-step explanation:
60-1.5 = 58.5 = money left for pants+tax
58.5/100 = 0.585 = 1%
0.585x 4= $2.34 = highest possible tax
58.5 - 2.34 = $56.16 most

In the standard (x,y) coordinate plane, point A has coordinates (–9,–1). Point A is translated 9 units to the right and 1 unit up, and that point is labeled A′. What are the coordinates of A′ ?
A.(-18,-2)
B.(-10,-10)
C.(-9,-2)
D.(0,0)
E.18,2)
Answers
Translation involves changing the position of a point in the coordinate plane.
The coordinate of the translated point A' is (D) (0,0)
The coordinate of the point is given as:
[tex]A = (-9,-1)[/tex]
The rule of translation 9 units right, and 1 unit up is:
[tex](x,y) \to (x+9,y+1)[/tex]
So, we have:
[tex]A' = (-9+9,-1+1)[/tex]
Simplify the expression
[tex]A' = (0,0)[/tex]
Hence, the coordinate of the translated point A' is (D) (0,0)

https://brainly.com/question/18549175
If the coordinate is translated 9 units right and 1 units up, the resulting coordinate will be at (-9 + 9, -1 + 1) which is A'(0, 0). Option D is correct
Given the coordinate point A (x, y), if the coordinate is translated a unit right and b units up, the resulting coordinate will be at (x + a, y + b)
Note that both values are added to the coordinate points.
Given the coordinate point A (-9, -1), if the coordinate is translated 9 units right and 1 units up, the resulting coordinate will be at (-9 + 9, -1 + 1) which is A'(0, 0)

find the y-intercept of the parabola y=x^2-5x+9/2
Answers
Answer:
To find the Y-intercept substitute in 0 for all the x's and solve for Y
Your answer would be (0,9/2)
Steps:
Y=0^2-5(0)+9/2
0^2 -5(0)=0
Y=9/2
0 is your x place
and 9/2 is your Y intercept
Answer:
y-intercept = 9/2 or 4.5
Step-by-step explanation:
In the given quadratic equation, y = x² - 5x + 9/2, where:
a = 1, b = -5, and c = 9/2
The y-intercept is the point at which the parabola crosses the y-axis, and occurs at point (0, c ). It is the value of y when x = 0. To find out what I mean by this, we can substitute the value of x = 0 into the quadratic equation:
y = x² - 5x + 9/2
y = (0)² - 5(0) + 9/2
y = 0 - 0 + 9/2
y = 9/2
Therefore, the y-intercept (c) = 9/2, and has coordinates, (0, 9/2) or (0, 4.5).
Attached is a screenshot of the graph, where it shows the y-intercept.

If a fair coin is tossed twice the possible outcomes are HH, HT, TH or TT, where HH means both tosses are heads and HT means that the first toss is a head and the second toss is a tail, etc. Since the coin is fair, a 50-50 chance of getting a head or a tail, we assign a probability of 1/4 to each of the four outcomes. Assuming that a fair coin was tossed twice, find the probability that both tosses were heads given that at least one of the tosses was a head. Round your answer to 4 decimal places.
Answers
The conditional probability value rounded to 4 decimal places is : 0.2500
The relation can be used to find the conditional probability of events given :
P(HH | Atleast 1 head) = P(HHn(Atleast 1 H)) / P(Atleast 1 H)
P(Atleast 1 H) = P(HT + TH + HH)
P(Atleast 1 H) = P(HT + TH + HH) = 3(0.25) = 0.75
P(HHn(Atleast 1 H)) = P(HH) × P(Atleast 1 H) = 0.25 × 0.75 = 0.1875
Therefore, the conditional probability can be expressed as :
P(HH | Atleast 1 head) = 0.1875 / 0.75 = 0.25Therefore, P(HH | Atleast 1 head) is 0.25

Carlos ate 1/3 of his caramel pie. Carlos is having a friend come over and wants to give her 1/4 of the pie he has remaining. What fraction of the original pie will he give his friend?
Answers
===================================================
Explanation:
Multiply the denominators to get 3*4 = 12. We'll use this value to set up the number of slices we start with.
If we started with 12 slices, then 1/3 of this is (1/3)*12 = 4 slices. So Carlos ate 4 slices. There are 12-4 = 8 slices left.
1/4 of that value is (1/4)*8 = 2 which is the number of slices given to his friend.
Divide the number of slices given to the friend (2) over the number we started with (12) to get 2/12 = 1/6
-----------------------
Another approach:
If Carlos ate 1/3 of the full pie, then there are 2/3 of it left.
1/4 of this is (1/4)*(2/3) = (1*2)/(4*3) = 2/12 = 1/6 which represents the fractional amount of the original pie given to the friend.

medical and dental insurance. Medical coverage costs $9,560
a year and dental coverage costs $172 a year. The restaurant
pays 80% of the medical and 65% of the dental insurance. How
much is deducted each week for insurance
Answers
Out of the weekly amount that Shashi Rimoko makes, a deduction of $37.93 is made for insurance.
The total Medical cost is $9,560 and out of this, the amount paid by Shashi per year is:
= Amount x (1 - percentage paid by restaurant)
= 9,560 x ( 1 - 80%)
= $1,912
The amount he pays for Dental coverage is:
= Amount x (1 - percentage paid by restaurant)
= 172 x (1 - 65%)
= $60.20
The total amount he pays for insurance per year is:
= Medical + Dental
= 1,912 + 60.20
= $1,972.20
The weekly deduction is:
= Year amount / No. of weeks in year
= 1,972.20 / 52
= $37.93
In conclusion, $37.93 is deducted from his paycheck every week.
