Graph the relation. Is the relation a function? Why or why not?
{(-5, 6), (-2, 3), (3, 2), (6, 4)}
Yes; there is only one domain value for each range value.
Yes; there is only one range value for each domain value.
No; a domain value has two range values.
No; a range value has two domain values.
Answer:
Yes; there is only one range value for each domain value.
Step-by-step explanation:
For a relation to be a function, every input, x-value, needs to have a unique output, y-value. This means that one x-value cannot have multiple y-values. So, in a function x-values will never repeat. Since x-values do not repeat in this relation, it is a function.
15. Which statements are true about
square EFGH? Select all that apply.
20.
P
E
н
A FP=2(EG)
© MZEFH = 45
DFH I EG
B) EP= EH
Answer:
[tex]EG \perp FH[/tex]
[tex]m\angle EFH = 45^\circ[/tex]
Step-by-step explanation:
Given
See attachment for square EFGH
Required
Select the true statements
The sides of the square are EF, FG, GH and HE while the diagonals are: EG and FH
The diagonals of a square meet at [tex]90^\circ[/tex] . This implies that: EG and FH are perpendicular i.e. [tex]EG \perp FH[/tex]
Also, the diagonals divide the angles at the edges ([tex]90^\circ[/tex]) into two equal angles ([tex]45^\circ[/tex])
This means that:
[tex]m\angle EFH = 45^\circ[/tex]
The other two options are false.
i.e.
[tex]EP \ne EH[/tex]
[tex]FP \ne 2(EG)[/tex]

Which linear function has a negative slope
Answer:
c
Step-by-step explanation:
in order for it to be a negative slope X has to be negative
Without graphing, find the slope of the line that goes through (-3, -2) and (-1, -5). *
-3/2
We can find slope using the equation (y2-y1)/(x2-x1). Substitute your values in for the xs and ys.
(-5 - (-2))/(-1 - (-3))
-3/2

When r = 2, the first expression is . 6
When r = 2, the second expression is 6.
When r = 5, the first expression is 21.
When r = 5, the second expression is .

just. determine if function or not
Ok so basically if an input (x) has more than one output (y) it is NOT a function. One output having more than one input is okay though.
So G) is a function, bc for every x there is just 1 y
H) is not a function
I) is not a function either
Then the 6 below ( i can't read their numbers so they're just gonna be 1-6, top 3 from left to right then the bottom three from left to right)
1. function
2. not a function
3. function
4. function
5. not a function
6. not a function
i might be wrong, but i hope this helps!
Answer:
G-Function, H-Not a function, I-Not a Function
Step-by-step explanation:
G is the only one that doesn't repeat its x values

Volume of cone= 1/3πr^2h
8842.24 m^3= 1/3πr^2h
1/3*3.14*33*r^2= 8842.24m^3
r^2 = 8842.24*3/3.14*33
r^2= 26526.72/103.62
r^2 = 256
r= √256
r= 16m

What is domain?The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). This set is the values that the function shoots out after we plug an x value in.
here, we have,
Given,
From the graph,
To find the domain of the function.
Now,
We know that a domain of a function is the set of the all the x-values for which the function is defined.
By looking at the graph of the function we see that it is a graph of a upward open parabola and the graph is extending to infinity on both the side of the x-axis this means that the function is defined all over the x-axis i.e. for all the real values.
Also, we know that the function will be a quadratic polynomial since the equation of a parabola is a quadratic equation and as we know polynomial is well defined for all the real value of x.
The domain of the function is:
Hence, All real numbers (In interval form (-∞,∞) )

1. Sonnie is selling her artworks in the form of stickers and bags tags for
summer vacation.
The stickers (y) cost P50 each and the bag tag (x) cost P75. She needs to sell at least P1000
worth of items.
a. Write an inequality to represent the income from the artworks sold.
b. Sonnie knows that she needs to make at least 15 stickers. Write an equality to represent this
situation,
c. Identify a solution. How many stickers and bags should Sonnie sell?
PA HELP plssssssss
Answer:
50y + 75x ≥ 1000 ;
50(15) ≥ 750;
x ≥ 4
y ≥ 15
Step-by-step explanation:
Given that :
Number of stickers sold = y
Cost of sticker = 50
Cost of bag tag = 75
Number of bag tags sold = x
Total worth of items sold ≥ 1000
1)
50y + 75x ≥ 1000
2.)
To make atleast 15 stickers
y ≥ 15
Atleast 15 stickers :
50(15) ≥ 750
3.)
A possible solution :
50(15) + 75(x) ≥ 1000
750 + 75x ≥ 1000
75x ≥ 250
x ≥ 3.33
x ≥ 4
y ≥ 15
Find the value of the variable(s). If your answer is not an integer, leave it in simplest radical form.
x=10/3 x=10,y=30/3 x=30.y=10/3
Answer:
Use the fact that sin(x) = opp/hyp and tan(x) = opp/adj
where opp=opposite, hyp=hypotenuse, adj=adjacent and recall sin(30)=1/2 and tan(30) = 1/sqrt(3)
sin(30) = 1/2 = 17/y
y = 17(2) = 34
tan(30) = 1/sqrt(3) = 17/x
x = 17sqrt(3)
So the answer is (d)
Note that you could have also use the Pythagorean theorem to find x instead of using tan(30).
Write an inequality relating NM and NL-
NM < NL
NM<_ NL
NM > NL
NM>_ NL
Answer:
NM > LN
Step-by-step explanation:
Here, we want to write an inequality
we should beat it in mind that, the greater the angle that a side of a triangle faces, the greater its length will be relatively
as we can see, the side NM faces the greater angle of 83, relative to the side LN that faces the angle of 56;
So we can conclude that;
NM > LN

NM > LN

A website received 2500 registered members in July. And the number of registered members in August decreased to 2245. What was the percentage decrease in the number of registered members?
Number of registrations a website received during July = 2500
Number of registrations a website received during August = 2245
Number by which the registrations decreased :
[tex] =\tt 2500 - 2245[/tex]
[tex] =\tt 255[/tex]
Thus, the registrations decreased by 255.
Let x be the perrcentage of decrease.
Which means :
[tex] =\tt 255 = \frac{x}{100} \: of \: 2500[/tex]
[tex] = \tt255 = \frac{x \times 2500}{100} [/tex]
[tex] =\tt 255 = \frac{2500x}{100} [/tex]
[tex] = \tt255 \times 100 = 2500x[/tex]
[tex] = \tt25500 = 2500x[/tex]
[tex] =\tt \frac{25000}{2500} = x[/tex]
[tex]\color{plum} =\tt \bold{10.2\%}[/tex]
▪︎Thus, the percentage of decrease in the number of registered members = 10.2%
