Section 3 - Topic 1 What is a Function? 1. A group of students were discussing whether the relationship on the graph is o function Ed: The relotionship is not a function because if I craw a horizontal line at y= 2, the horizon al line crosses the graph ot two points. Debra: The relationship is a function because it is a graph of two different Alejandro: The relationship is not a function because x = 1 has two different y-values. Antoine: The relationship is a function because I can write an equation for diline. Which students are not correct and whot is the flow in their argument:
9514 1404 393
Answer:
Not correct: Ed, Debra, Antoine
Step-by-step explanation:
Ed is incorrect because he is using a horizontal line test instead of the appropriate vertical line test.
Debra is incorrect because the fact it is two different lines is irrelevant. A piecewise linear function may be two or more different lines.
Antoine is incorrect because the existence of an equation for the curve has nothing to do with whether or not it is a function. (Here, Antoine would need two equations with overlapping domains. The overlap of the domains is what tells you it is not a function.)
__
Alejandro is correct. The relation fails the vertical line test

A man and a woman start from the same point. The man walks S60°E at 1.3 m/sec. The woman
walks south at 1.6 m/sec. At what rate is the distance between the man and woman changing
after 35 minutes?
Answer:
The distance between the man and woman is changing at the rate of 1.5 m/sec.
Step-by-step explanation:
Speed = [tex]\frac{distance}{time}[/tex]
⇒ distance = speed x time
After 35 minutes (2100 seconds) ,
the man has walked a distance = 1.3 x 2100
= 2730 m
After 35 minutes, the woman has walked a distance = 1.6 x 2100
= 3360 m
The sketch of the displacement of the man and woman forms a triangle with an included angle. Applying the cosine rule, we have:
[tex]c^{2}[/tex] = [tex]a^{2}[/tex] + [tex]b^{2}[/tex] - 2abCos θ
= [tex]3360^{2}[/tex] + [tex]2730^{2}[/tex] - 2 x 3360 x 2730 x Cos [tex]60^{o}[/tex]
= 11289600 + 7452900 - 18345600(0.5)
= 18742500 - 9172800
= 9569700
c = [tex]\sqrt{9569700}[/tex]
= 3093.5 m
The distance between the man and woman at 35 minutes is 3093.5 m.
The distance between the man and woman is changing at the rate = [tex]\frac{3093.5}{2100}[/tex]
= 1.4731
= 1.5 m/sec
The distance between the man and woman is changing at the rate of 1.5 m/sec.
help idk how to do this whats the answer plz
Answer:
79 degrees i think
Step-by-step explanation:
Lines that are horizontal and straight are always 180 degrees so i just subtracted 180 degrees from 101 and i got 79 degrees
Answer:
x = 79
Step-by-step explanation:
A straghit line is equal to 180 degrees.
If 101 of it is taken, you have to find out what the other side is equal to.
The equation would look like: 101 + x = 180 or 180 - 101 = x
I hope you understand now! :D

What is an equation of the line that passes through the point (-5,7) and is parallel
to the line 3 - 5y = 15?
Answer
y=0x+7
Step-by-step explanation:
Parallel lines share the same slope, to solve, you need to find the slope of the line it is parallel to.
3-5y=15, since this equation has no x value, that basically means that the slope is 0.
Since the slope is 0 and you have an ordered pair, you can now substitute the ordered pair and the slope into slope intercept form to solve for 'b' or the y intercept.
y=mx+b
(-5,7)
7=0(-5)+b
b=7
y=0x+7

2,000 + 400 + 90 + 2
24,000 + 900 + 2
20,000 + 4,000 + 90 + 2
20,000 + 4,000 + 900 + 0 + 2

1/3+4/9= please help
Answer:
7/9
Step-by-step explanation:
Answer:
It equals 7/9
Step-by-step explanation:
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(1/3×3/3)+(4/9×1/1)=?
Complete the multiplication and the equation becomes
3/9+4/9=?
The two fractions now have like denominators so you can add the numerators.
Then:
3+4
------- =7/9
9
This fraction cannot be reduced.
Therefore:
1/3+4/9=7/9

Complete the solution of the equation. Find
the value of y when x equals 12.
x + 3y = 21
Answer:
y=3
Step-by-step explanation:
12+3y=21
-12 -21 subtract 12 from both sides
------------------
3y=9
divide 3 from y and 9, so you can get y by itself
3y/3= y 9/3= 3
so y is equal to 3

Alan's hair was 15 centimeters long after his last haircut, and it grows 7 centimeters every year. How many years will it take until Alan's hair is 43 centimeters long?
Answer:
4 years
Step-by-step explanation:
After his haircut he has 15 centimetres of hair, this is our origin. If we take 15 + 7 and multiply it by 4 then our answer would be 43

Step 2 of 2: Calculate the population variance for the response time. Round any intermediate calculations, if needed, to no less than four decimal places, and round
your final answer to two decimal places.
Answer: σ² = 2.90
Step-by-step explanation: For a frequency table, population variance is calculated by:
[tex]\sigma^{2}=\frac{\Sigma f(x-\mu)^{2}}{\Sigma f}[/tex]
where
f is frequency
μ is expected value or mean of the distribution
In this case, mean of the distribution for a grouped frequency table is calculated by:
[tex]\mu=\Sigma x.f(x)[/tex]
where
x is (as the data is grouped) the mid value of the response time
So, the table is
x | f
6.45 | 18
7.45 | 21
8.45 | 34
9.45 | 46
10.45 | 46
11.45 | 25
12.45 | 21
And mean will be:
[tex]\mu=6.45(18)+7.45(21)+8.45(34)+9.45(46)+10.45(46)+11.45(25)+12.45(21)[/tex]
μ = 9.5874
To calculate the variance, the formula above is transformed into
[tex]\sigma^{2}=\frac{\Sigma f.x^{2}-\frac{(\Sigma f.x)^{2}}{\Sigma f} }{\Sigma f}[/tex]
So, to facilitate the calculations, divide each term in a table:
f | x | f.x | f.x²
18 | 6.45 | 116.1 | 748.845
21 | 7.45 | 156.45 | 1165.5525
34 | 8.45 | 287.3 | 2427.685
46 | 9.45 | 434.7 | 4107.915
46 | 10.45 | 480.7 | 5023.315
25 | 11.45 | 286.25 | 3277.5625
21 | 12.45 | 261.45 | 3255.0525
∑ 211 | | 2022.95 | 20005.9275
Population variance will be:
[tex]\frac{(\Sigma f.x)^{2}}{\Sigma f} =[/tex] [tex]\frac{(2022.95)^{2}}{211}[/tex] = 19394.9133
[tex]\sigma^{2}=\frac{\Sigma f.x^{2}-\frac{(\Sigma f.x)^{2}}{\Sigma f} }{\Sigma f}[/tex]
[tex]\sigma^{2}=\frac{20005.9275-19394.9133}{211}[/tex]
σ² = 2.90
The population variance for the response time for EMTs is 2.90.

HELP PLEASE GOD I HAVE A DAY HELP!!!!) A daycare employee earns $10.90 per hour for the first 40 hours he works in 1 week. He is paid 1.5 times that rate for each additional hour that he works. How much money does he earn working for 43 hours in 1 week?
Answer:
$485.05 per week of 43 hours labor
Step-by-step explanation:
First of all, we already know that he works the first 40 hours, so:
$10.90*40= $436
Now it says the next three hours are 1.5* the original pay;
$10.90*1.5= $16.32 (x 3 because thats the extra hours)
$16.32*3 = $49.05
Now, we add the numbers:
$436+$49.05= $485.05
All done!
