Write an equation of the line graphed in slope-intercept form:
Answer:
-2.5x+2
I hope this is good enough:
y-intercept is at positive 2 so you would have +2
it has a negative slope because it is going downwards
on the graphing calculator I used 2 wasn't big enough to make the x intercept and 3 was to big so I went in the middle and it looked correct.

A city’s population is currently 150,00. If the population doubles every 30 years, what will the population be 60 years from now?
Answer:
60000
Step-by-step explanation:
AFTR 30 YEARS =15000*2=30000
AFTR 60 YEARS=30000*2=60000
First of all, the population is 15,000 NOT 150,00. Do you know why?
After 30 years, 15,000 doubles to become 30,000.
60,000 is twice 30,000.
So, after another 30 years, 30,000 people increases to 60,000.
Find the mean proportional for each pair. SHOW YOUR SOLUTION
1. 6, 24
Answer:
The mean proportional of 6, and 24 will be 12
Step-by-step explanation:
We know that the Mean proportional of two
numbers, x, and y : [tex]\sqrt{xy}[/tex]
Therefore, the mean proportional of 6, and 24
[tex]=\sqrt{6\times 24}[/tex]
[tex]=\sqrt{144}[/tex]
[tex]\mathrm{Factor\:the\:number:\:}\:144=12^2[/tex]
[tex]=\sqrt{12^2}[/tex]
[tex]\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{a^n}=a[/tex]
[tex]\sqrt{12^2}=12[/tex]
[tex]=12[/tex]
Therefore, the mean proportional of 6, and 24 will be 12.

I'm more than 9 dozen and less than the number of days in 4 months. The sum of my digits is 11.
Answer: 92 or 119
in 4 months, 2 months with 30 days per month, 2 months with 31 days per month
suppose: the number to find is X
have: 90 < X < 30.2 + 31. 2 ⇔ 90 < X < 122
if X is a number has 2 digits => X is xy
=> [tex]\left \{ {{x+y=11} \atop {90<x\leq 100}} \right.[/tex]
=> xy = 92
if X is a number has 3 digits => X is abc
we have: [tex]\left \{ {{a+b+c=11} \atop {100\leq abc<122}} \right.[/tex]
because 100 ≤ abc < 122 => a = 1; b = 0 or 1
+) if a =1 ,b = 0 but a+ b +c = 11 => c = 10 (removed because c is a 1-digit number)
+) if a = 1, b = 1 => c = 9
=> abc = 119
=> X is 92 or 119

-3+|n-2|>5
How would you solve this?
Answer:
3n-6>5
3n>5+6
3n>11
n>11/3
n>3.6
Answer:
n < 1/3
Step-by-step explanation:
-3(n-2) > 5
-3n + 6 > 5
-3n > 5 - 6
-3n > -1
n > -1/-3 (flip the sign of the inequality because you divided by a negative number)
Hence, n < 1/3 OR n < 0.333

25+15=40
The required cost of a standard member is $25 as of the given condition.
Given that,
The monthly dues for a premium membership at a health club is $15 more than the cost of a standard membership. The premium membership is $40.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
here,
Let the cost of the standard membership be x,
According to the question,
x = 40 - 15
x = 25

The statement which best describes the value of the expression at; x = 1 is; Choice D; The result is a whole number that is neither prime nor composite.
Which of the statements best describes the value of the expression 5x – 4 when x = 1?It follows from the task content that the value of the expression be determined at; x = 1 and consequently, the result be classified as a whole number, prime number or composite number.
Hence, when x = 1;
5x - 4 = 5(1) - 4.
= 5 - 4
= 1.
Hence, the result is 1 which can be classified as a whole number (integer). However, it is not a prime number and neither is it a composite number.

If V is the circumcenter of triangle PQR, find the length of PV.
Round to the nearest tenth, if necessary.
PLS HELP FOR GEOMETRY
9514 1404 393
Answer:
22.8
Step-by-step explanation:
The circumcenter is equidistant from all the vertices of the triangle: PV = RV. There are enough dimensions given to let us find RV from the Pythagorean theorem.
RV² = RS² +SV²
RV² = 11² +20² = 521
RV = PV = √521 ≈ 22.8

However, the department of transportation has recently changed most of them to agree with the numbers on the mile markers along the highway.

Nominal ordinal ratio interval (c) the newer system provided information on the distance between exits.
a. True
b. False
Answer:
Following are the answer to this question:
In question, a) ordinal.
In question, b) ratio .
In question, c) true.
Step-by-step explanation:
For its "ordained" existence, regular data is used to conduct surveys and questionnaires. To identify respondents into different categories, a quantitative methodology is employed to sufficient excess.
Its ratio data is defined as a statistical method with the same features as continuous variables, that recognize the proportion of each data to an absolute null as its source. In many other words, the meaning of the line graph may not be positive.
Its newest program gives the gap between exits data.

Answer:
B. [tex]\frac{\sqrt{3}}{11}, \frac{\pi}{24}, \frac{3}{25}, \frac{9}{100}[/tex]
Step-by-step explanation:
The question is not properly presented. See attachment for proper presentation of question
From the attachment, we have that:
[tex]W = \frac{3}{25}[/tex]
[tex]X = \frac{\sqrt{3}}{11}[/tex]
[tex]Y = \frac{9}{100}[/tex]
[tex]Z = \frac{\pi}{24}[/tex]
Required
Order from greatest to least
First, we need to simplify each of the given expression (in decimals)
[tex]W = \frac{3}{25}[/tex]
[tex]W = 0.12[/tex]
[tex]X = \frac{\sqrt{3}}{11}[/tex]
Take square root of 3
[tex]X = \frac{1.73205080757}{11}[/tex]
[tex]X = 0.15745916432[/tex]
[tex]X = 0.16[/tex] --- approximated
[tex]Y = \frac{9}{100}[/tex]
[tex]Y = 0.09[/tex]
[tex]Z = \frac{\pi}{24}[/tex]
Take π as 3.14
[tex]Z = \frac{3.14}{24}[/tex]
[tex]Z = 0.13083333333[/tex]
[tex]Z = 0.13[/tex] --- approximated
List out the results, we have:
[tex]W = 0.12[/tex] [tex]X = 0.16[/tex] [tex]Y = 0.09[/tex] [tex]Z = 0.13[/tex]
Order from greatest to least, we have:
[tex]X = 0.16[/tex] [tex]Z = 0.13[/tex] [tex]W = 0.12[/tex] [tex]Y = 0.09[/tex]
Hence, the order of arrangement is:
[tex]X = \frac{\sqrt{3}}{11}[/tex] [tex]Z = \frac{\pi}{24}[/tex] [tex]W = \frac{3}{25}[/tex] [tex]Y = \frac{9}{100}[/tex]
i.e.
[tex]\frac{\sqrt{3}}{11}, \frac{\pi}{24}, \frac{3}{25}, \frac{9}{100}[/tex]
