#1.) What is the slope between point C and Point D? *Please Show All Work*
#2.) What is the equation of the line (Slope-Intercept Form: y = mx + b) that represents the climb from Point C to Point D? *Please Show All Work*
#3.) What is the domain and range the C to D part of the roller coaster?
Let's see what to do buddy....
_________________________________
1) Go...
We have the following equation for finding the slope of the line by using two points :
[tex]slope = m = \frac{y(b) - y(a)}{x(b) - x(a)} \\ [/tex]
Where a and b are the points which the line through them.
We have points C and D here ,
So :
[tex]slope = m = \frac{y(d) - y(c)}{x(d) - x(c)} \\ [/tex]
D = ( 7 , 12 ) and C = ( 0 , 0 )
Now just need to put the coordinates in the above equation :
[tex]slope = m = \frac{12 - 0}{7 - 0} = \frac{12}{7} \\ [/tex]
_________________________________
2) Go...
We have the following equation to find the point-slope form of the linear functions :
[tex]y - y(o) =(slope) \times ( \: x - x(o) \: ) \\ [/tex]
Where o is one of the given points.
So we must choose one of the points ,
I choose : D = ( 7 , 12 )
Then we have :
[tex]y - 12 = \frac{12}{7}(x - 7) \\ [/tex]
It's point-slope form, so we need to simplifies it to find slope-intercept form.
Look:
[tex]y - 12 = \frac{12}{7}x - 12 \\ [/tex]
Both sides plus 12
[tex]y = \frac{12}{7}x \\ [/tex]
Now we have the slope-intercept form of the CD line.

3) Go...
Domain = [ 0 , 7 ]
Range = [ 0 , 12 ]

And we're done.

Cooper is a salesperson who sells computers at an electronics store. He makes a base pay amount of $ 60 per day regardless of sales and he earns a commission of 1.5% of the dollar amount of all sales that he makes. Write an equation for P, in terms of x, representing Cooper's total pay on a day on which he sells z dollars worth of computers.
Answer:
P = 0.015x + 60
Step-by-step explanation:
Since Cooper's base pay is $60, he would earn $60 even for selling $0 worth of computers, meaning P= 60 when x=0, which is the y-intercept.
(0,60) is a point on the graph
Since Cooper makes a commision of 1.5% for all sales, the amount of money earned in a given day increases $0.015 for each $1 of sales made (multiply 1 by 0.015). This means the slope of P is equal to 0.015.

7,8,15 Is this a triangle? Explain.
5,6,10 Is this a triangle? Explain.
Please help me figure these problems out with the correct answers the last guy said they were all not triangles and my teacher said they were incorrect who ever answers and explains correctly gets 31 points and gets marked brainliest you have all the time you need so answer wisely. This shouldn't take long don't answer something your not similar with.
Problem 1
Answer: Yes a triangle can be formed with side lengths 5,5,3
--------------------
Explanation:
Take any two sides and add them up. If we get a sum larger than the third side, then a triangle is possible. This is the triangle inequality theorem.
5+5 = 10 is larger than 3
5+3 = 8 is larger than 5
This shows a triangle is possible. The triangle is isosceles because two sides are the same length.
==========================================================
Problem 2
Answer: Yes a triangle can be formed with side lengths 8,8,8
--------------------
Explanation:
This triangle is equilateral because all sides are the same length.
Take any two sides, add them up, and you'll find the sum is larger than the third side.
==========================================================
Problem 3
Answer: No a triangle cannot be formed with sides 7,8,15
--------------------
Explanation:
Yes it is true that
8+15 = 23 is larger than 7
7+15 = 22 is larger than 8
but
7+8 = 15 is not larger than 15
So this means a triangle is not possible.
Imagine you had 3 strips of paper that were 7 inches, 8 inches and 15 inches long. The 7 and 8 inch strips add to 15 inches, but those two smaller strips only form a straight line. We cannot pull them so a triangle forms. If we did, then the third side would be smaller than 15 inches. This is one way to get hands on to see why the triangle inequality theorem works.
==========================================================
Problem 4
Answer: Yes a triangle is possible with side lengths 5,6,10
--------------------
Explanation:
Same idea as before. We can take any two sides, add them, and get a sum larger than the third side. A triangle is possible.
5+6 = 11 is larger than 106+10 = 16 is larger than 55+10 = 15 is larger than 6If David saves 5% of his $100

What is the measure of the missing angle?
280
78°
Answer:
2 degrees
Step-by-step explanation:
There is 360 degrees in a circle, triangle, square, and a ton of other shapes, and 280 plus 78 gives you 358 degrees. 360 - 358 equals 2 degrees.

The height h and collar size c , both in centimeters, measured from a sample of boys were used to create the regression line cˆ=−94+0.9h . The line is used to predict collar size from height, both in centimeters, for boys’ shirt collars. Which of the following has no logical interpretation in context?
Answer:
The C=intercept of the regression line
Step-by-step explanation:
The slope of the regression line has a logical interpretation as the average rate of change in collar size for a 1cm increase in height.
A linear regression is represented as [tex]^\wedge y = mx + c[/tex]
The option that has no logical interpretation is: E The c-intercept of the regression line
From the question, we have:
[tex]^\wedge c = 94 + 0.9h[/tex]
Using the above representation of a regression line [tex]\wedge y = mx + c[/tex]
[tex]m \to[/tex] the slope
[tex]c \to[/tex] the y-intercept
By comparing [tex]\wedge y = mx + c[/tex] to [tex]^\wedge c = 94 + 0.9h[/tex]
[tex]0.9 \to[/tex] slope
[tex]94 \to[/tex] the y-intercept
While [tex]^ \wedge c[/tex] and [tex]h[/tex] are the variables (i.e. collar size and height)
From the list of given options (see attachment), the option that has no logical interpretation is:
E. The c-intercept of the regression line
This is because c does not represent the intercept of [tex]^\wedge c = 94 + 0.9h[/tex]

In a sales effectiveness seminar, a group of sales representatives tried two approaches to selling a customer a new automobile: the aggressive approach and the passive approach. For 1160 customers, the following record was kept:
Sale No Sale Row Total
Aggressive 255 325 580
Passive 472 108 580
Column Total 727 433 1160
Suppose a customer is selected at random from the 1160 participating customers. Let us use the following notation for events: A = aggressive approach, Pa-passive approach, S-sale, N = no sale. So, P(A) is the probability that an aggressive approach was used, and so on.

Determine the slope for each side of the polygon.
The slope of side w is: _
The slope of side z is:_
The slope of side x is: _
The slope y is : _
Answer:
The slope of side w is: ¼
The slope of side z is: -4
The slope of side x is: ¼
The slope y is : -4
Step-by-step explanation:
Slope of w between (-1, 5) and (-5, 4):
[tex] slope(m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{4 - 5}{-5 -(-1)} = \frac{-1}{-4} = \frac{1}{4} [/tex]
Slope of x between (-3, -4) and (1, -3):
[tex] slope(m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-3 -(-4)}{1 -(-3)} = \frac{1}{4} = [/tex]
Slope of y between (-3, -4) and (-5, 4):
[tex] slope(m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{4 -(-4)}{-5 -(-3)} = \frac{8}{-2} = -4 [/tex]
Slope of z between (1, -3) and (-1, 5)):
[tex] slope(m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{5 -(-3)}{-1 - 1} = \frac{8}{-2} = -4 [/tex]
