Slope means m
1. AB = Slope is 3/4, CD = Slope is 0
2. AB = Slope is 2/5, CD = Slope is -5/2
Rise / Run
1. ) A (( -2 (x1) , 3 (y1) )), B (( 2 ( x2) , 6 (y2))
m = y2 - y1 / x2 - x1
m = 6 - 3 / 2 - (-2) = 3/4 (AB)
C (( -1 (x1) , 0 (y1)) , D (( 3 (x2) , 3 (y2))
m = 3 - 0 / 3 - (-1) = 0 / 4 = 0 (CD)
2. ) A (( 0 ( x1) , 2 ( y1 )) , B (( 5 ( x2 ) , ( 4 ( y2))
m = 4 - 2 / 5 - 0 = 2/5 (AB)
m = 3 - 8 / 3 - 1 = -5/2 (CD)

Answers
Answer:
Step-by-step explanation:
Price of cellophone = ₹4500
Gst additionally = 12%
= 12% of ₹4500

We know that to find the radius, we divide the diameter by 2, so the first one is correct.We know that the second one is incorrect because we just said that we would divide the diameter by 2 for the radius, so we would multiply the radius by 2 to find the diameter.The third statement is correct because the circumference is approximately 3 times bigger than the diameter.The fourth statement is correct because the circumference is equal to pi times 2 times the radius.If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers.

Sorry, I couldn't figure out the last one, it just takes a lot of trial and error and luck :(
You know that S times A is the digit N. Then, A squared plus whatever the first digit of the2 digit number XN is MA.
A cannot be five because if you were to do 5 times 5 it would be 25. A squared is 25 and the last digit is already A so added on to anything else the equation would be false. So the only considerable value for S would be one, but then A times S would be 5, but N is not A. I hope you get what I mean.
A cannot be 6 for the same reason (just change the 5 to six on my last pragraph).
If A were 7 then you'd have to find something to add to 49 to make it end in 7, which means adding 6. 7 times 9 is 63, so S could be 9. 79 times 7 is 573. That is the answer. A = 7, S = 9, M = 5, N = 3.
As for NINE - FOUR = FIVE, E - R is E so R must be 0.The only one digit number a number can be subtracted by to get itself is 0.
Now, N - U = V, or 1N - U = V
Let's say N is 3 and U is 6. V would be 7.
We've just took one from I. I - 1 - O = I. 1+O must be 10 or 0, but O must be positive, so O = 9. Let's say I is 5.
We just borrowed one form N. N-1 - F = F. N - 1 = 2 times F.
But we know that N is 3. 2 = 2 times F. F is 1.
Let's just make E = 8
My final answer is 3538 - 1960 = 1578
There are MANY other answers though.
N = 3, I = 5, E = 8, O = 9, U = 6, R = 0, V = 7.

and let y= height in feet. Round all numbers to the nearest hundredth.
(b) Use the equation to estimate the height of rocket after 5 seconds.
Answers
The height of the rocket after 5 seconds would be 0 feet.
What is an quadratic equation?A quadratic equation is in the form:
y = ax² + bx + c
Let y represent the height after x seconds.
At point (0, 0):
0 = a(0)² + b(0) + c
c = 0
At (0.5, 20.5):
20.5 = a(0.5)² + b(0.5) +0
0.25a + 0.5b = 20.5
At point (2, 36.25):
30.41 = a(2)² + b(2) + 0
4a + 2b = 30.41
Hence:
a = -17.2, b = 49.6
Hence:
y = -17.2x² + 49.6x
At 5 seconds:
y = -17.2(5)² + 49.6(5) = -197
The height of the rocket after 5 seconds would be 0 feet.

What is the average rate of change of the line whose equation is:
y−3=−12(x+4)?
PLEASE HELPPPP
Answers
Answer:
Rate of change = -12
Step-by-step explanation:
y − 3 = −12(x + 4)
Expanding, we have;
y - 3 = -12x - 48
y = -12x - 48 + 3
y = -12x - 45
Now, formula for rate of change is;
Rate of change = (y(x + h) - y)/h
y(x + h) is; y = -12(x + h) - 45
This gives;
Rate of change = (-12(x + h) - 45 + 12x + 45)/h
Rate of change = (-12x - 12h - 45 + 12x + 45)/h
Rate of change = -12h/h
Rate of change = -12

An investment website can tell what devices are used to access their site. The site managers wonder whether they should enhance the facilities for trading via smartphones so they want to estimate the proportion of users who access the site that way. They draw a random sample of

investors from their customers. Suppose that the true proportion of smartphone users is
26
%.
Complete parts a) through c) below.
a) What would the managers expect the shape of the sampling distribution for the sample proportion to be?
Skewed to the left
Unimodal and symmetric
Skewed to the right
Nonsymmetric
b) What would be the mean of this sampling distribution?
(Round to two decimal places as needed.)
c) What would be the standard deviation of the samplingdistribution?
(Round to three decimal places as need
Answers
Answer: a) Unimodal and symmetric
b) 0.26
c) 0.038
Step-by-step explanation:
Given: Sample size of investors (n)= 131
True proportion of smartphone users(p) =26%
a) Since sampling distribution for the sample proportion is approximately normal when n is larger.
Normal distribution is Unimodal and symmetric.
So correct option : Unimodal and symmetric
b) mean of this sampling distribution = p = 0.26
c) standard deviation of the samplingdistribution = [tex]\sqrt{\dfrac{p(1-p)}{n}}=\sqrt{\dfrac{0.26\times (1-0.26)}{131}}=\sqrt{0.00146870229008}[/tex]
