HELPPPPPPPPPPP NEEDED PLEASEEEEEEEEEE
Answer:
It is not a function.
Step-by-step explanation:
Using the verticals line test you can tell the relation is not a function because two number are the same in the x-value. This can be easily seen with the two points on the same vertical line.
The shorter diagonal of a rhombus measures 18cm. The side of the rhombus measures 41cm. Find the length of the longer diagonal.
Answer:
80 cm
Step-by-step explanation:
BO² = AB² - AO²
BO² = 41² - 9² = 1,600 = 40²
BD = 2× BO = 80 cm

HELPPP, i did it but i’m not sure if it’s right thank uu
You have the correct sequence of reasons
Here's what the full step by step picture looks like
3.25(1.25x + 0.5) = 10.5 ................ given
4.0625x + 1.625 = 10.5 ................ distributive property
4.0625x = 8.875 ................ subtraction property of equality
x = 2.18461538461539 ....... division property of equality
---------------------------
Notes:
The decimal value of x is approximate. Round it however you need.In the third step, we subtracted 1.625 from both sidesIn the fourth step, we divide both sides by 4.0625Answer:
I am pretty sure that is right
Step-by-step explanation:
[tex]3.25(1.25+0.5) = 10.5[/tex] is given
Then you distribute the [tex]3.25\\[/tex] to the [tex]1.25x[/tex] and the [tex]0.5[/tex].
[tex]3.25(1.25x)=4.06x[/tex]
[tex]3.25(0.5)=1.6[/tex]
So the new equation would be [tex]4.06x + 1.6= 10.5[/tex]
Then you would subtract [tex]1.6[/tex] from each side to get [tex]4.06x=8.9[/tex]
Finally you would divide each side by [tex]4.06[/tex] to get [tex]x= 1.93[/tex].

Shortly after creating a car washing business, you made $65 washing ten
cars. Then after fifteen cars, you made $115. Build a model. Write an
explanation for the slope. Write an explanation for the y-intercept. How
many cars have you washed if you have made $255?
Answer:
A) For the slope;
Rate of change in profit per change in number of cars washed = 10
B) when he had not washed any car, he was in debt of of $35
C) When he made $255, he had washed 29 cars
Step-by-step explanation:
Slope intercept equation of a line is;
y = mx + c
you made $65 washing ten
cars. Thus, x = 10 and y = 65
So, 65 = 10m + c - - - - (eq 1)
Then after fifteen cars, you made $115.
Thus, x = 15 and y = 115
So; 115 = 15m + c - - - - (eq 2)
Subtract equation 1 from eq(2) to get;
115 - 65 = 15m - 10m + c - c
50 = 5m
m = 50/5
m = 10
Putting 10 for m in eq 1 gives;
65 = 10(10) + c
65 = 100 + c
c = 65 - 100
c = -35
A) Since the slope is m = 10 and slope is m = Δy/Δx, it means that;
Rate of change in profit per change in number of cars washed = 10
B) c = -35 is the y-intercept.
This means when x = 0, y = - 35.
It implies that when he had not washed any car, he was in debt of of $35
C) since we have the slope and intercept, equation is;
y = 10x - 35
If he has made $255,then we have;
255 = 10x - 35
255 + 35 = 10x
290 = 10x
x = 290/10
x = 29 cars washed.
Which is equivalent to 4(x - 1)

Guests at a Beaumont hotel stay for an average of 9 days with a standard deviation of 2.4 days. Assume that the length of stay is normally distributed. Assume that we select randomly 1000 guests. How many of those guests can be expected to stay between 7 and 14 days
Answer:
778
Step-by-step explanation:
We have the length of stay as X
X~N (9,(2.4))
The sample is given as n = 1000
P(7<x<14) is what we are trying to get
P(7-9/2.4 < x-9/2.4 < 14-9/2.4)
= P(-0.83<z<2.08)
P(z<2.08)-p(z<-0.83)
When we go to the z table,
0.981-0.0203
= 0.778
0.778x1000
= 778
So in conclusion, 778 of these guests can be expected to stay between 7 and 14 days.

Vhich graph shows the solution of the inequality X+5 > 2?
Answer:
X>−3
Step-by-step explanation:
Subtract 5 from both sides.
X>2−5
Simplify 2-5 to -3
ANNNNND THE ANSWER IS
X>−3
The solution is, the value of the given inequality is : X>−3.
What is inequality?An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.
here, we have,
given that,
the given inequality is:
X+5 > 2
Subtract 5 from both sides.
X+5- 5 > 2 - 5
X>2−5
Simplify,
2-5 = -3
so, we get,
AND THE ANSWER IS
X>−3
Hence, The solution is, the value of the given inequality is : X>−3.
