What is the slope, m, of the line through (-7, -2) and (-6, 7)?
Answer:
Slope = 9
Step-by-step explanation:
(-7 , -2) ; x₁ = -7 and y₁ = -2
(-6 , 7) ; x₂ = -6 and y₂ = 7
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]=\frac{7-[-2]}{-6-[-7]}\\\\=\frac{7+2}{-6+7}\\\\=\frac{9}{1}\\\\= 9[/tex]

What are fit equations?Fitting an equation to data is finding a linear, quadratic, exponential, or any other sort of function whose graph includes, or comes as close as possible to, a given set of data in the form of ordered pairs. The relative predictive power of a model shows how accurately the model is related to the data.
The theoretical pattern best accounts for the relationships among variables in a data set. For example, a regression equation having the best fit to sample data is the one that minimizes differences between observed and predicted values.

In 1985 an antique automobile club had 23,000 members. Since then its membership has grown at an average rate of 5% per year. Assuming this trend continues, how many members will there be in 2020? Round to the nearest thousand.
a) 112,000 members
b) 78,000 members
c) 151,000 members
d) 127,000 members
Answer:
I have come to the conclusion that it is A. 112,000
Answer:
d) 127,000 members
Step-by-step explanation:
In this problem we have an exponential function of the form
where a is the initial value
b is the base
The base is equal to b=1+r
r is the average rate
In this problem we have a=23,000 members
r=5%=5/100=0.05
b=1+0.05=1.05
substitute
x ----> is the number of years since 1985
How many members will there be in 2020?
x=2020-1985=35 years
substitute in the function
Round to the nearest thousand

Solve for x.

120
Answer:
x = 10
Step-by-step explanation:
Let's draw the center of the circle S and the segments SE and SD.
SE is perpendicular to EF (as EF is tangent to circle).
That means FED + DES = 90deg
We also know that DSE = 120deg
And because the SED is an isosceles triangle, we know that angle measures for DES and SDE are equal.
DES = (180deg - 120deg) / 2 = 30deg
FED = 90deg - DES = 90deg - 30deg = 60deg

at time t, the position of a body moving along the s-axis is s=t^3 - 12t^2 + 36t m. Find the total distance traveled by the body from t=0 to t=3.
Answer:
27 m
Step-by-step explanation:
The position of a body is given by :
[tex]s=t^3 - 12t^2 + 36t[/tex]
We need to find the total distance traveled by the body from t=0 to t=3.
At t = 0,
[tex]s=0^3 - 12(0)^2 + 36(0)=0\ m[/tex]
At t = 3 s,
[tex]s=(3)^3 - 12(3)^2 + 36(3)\\\\=27\ m[/tex]
So, the total distance from t=0 to t=3 is equal to 27 m.

A survey of 64 informed voters in Kenya revealed the following information:
45 believe that Voting is a waste of time
49 believe that they have been abducted by space aliens
42 believe both of these things
REQUIRED
i). How many believe neither of these things?
ii). How many believe Voting is a waste of time but don't believe that they have been
abducted by space aliens?
Answer:
i) 12 believe neither of these things.
ii) 3 believe voting is a waste of time but don't believe that they have been abducted by space aliens.
Step-by-step explanation:
I'm going to solve these question treating these events as Venn sets.
I am going to say that:
Event A: Voting is a waste of time.
Event B: They have been abducated by space aliens.
45 believe that Voting is a waste of time
This means that [tex]A = 45[/tex]
49 believe that they have been abducted by space aliens
This means that [tex]B = 49[/tex]
42 believe both of these things
This means that [tex]A \cap B = 42[/tex]
i). How many believe neither of these things?
Total of 64.
At least one is:
[tex]A \cup B = A + B - A \cap B[/tex]
With the values we have
[tex]A \cup B = 45 + 49 - 42 = 52[/tex]
None:
[tex]64 - 52 = 12[/tex]
12 believe neither of these things.
ii). How many believe Voting is a waste of time but don't believe that they have been abducted by space aliens?
This is:
[tex]A - B = A - (A \cap B) = 45 - 42 = 3[/tex]
3 believe voting is a waste of time but don't believe that they have been abducted by space aliens.

Find the surface area of the
rectangular prism.
4 ft.
12 ft.
9 ft.
[? ] sq ft.
Answer:
384Step-by-step explanation:
Given,
Dimensions of the rectangular prism = 9ft, 12ft and 4ft
Therefore,
Surface area of the rectangular prism
= 2( lb + bh + lh)
[tex] = 2(12 \times 9 + 9 \times 4 + 12 \times 4) {ft}^{2} [/tex]
[tex] = 2(108 + 36 + 48) {ft}^{2} [/tex]
[tex] = 2 \times 192 {ft}^{2} [/tex]
[tex] = 384 {ft}^{2} [/tex]
Hence,
Surface area of rectangular prism is 384 sq. ft (Ans)

Answer: The value of [tex]g(a+2)=5a-8[/tex].
Step-by-step explanation:
We are given that,
[tex]g(x)=5x-2[/tex] ...(i)
To find: [tex]g(a+2)[/tex]
Substitute [tex]x=a+2[/tex] in (i), we get
[tex]g(a+2)=5(a+2)-2\\\\g(a+2)=5a+10-2\\\\g(a+2)=5a+8[/tex]
Therefore, the value of [tex]g(a+2)=5a-8[/tex].

Answer:
This is the famous "Ice cream cone" problem. notice that if you turn the object 90° counter clock wise , it looks like an ice cream cone. anyway
Step-by-step explanation:
the two triangles on the pointy end make a box , if you put them together, so it's a box of 4 x 11 or 44 [tex]in^{2}[/tex].
then the actual box part in the middle it's 3 x 8 or 24 [tex]in^{2}[/tex].
and finaly the ice cream :P or the round part. well half round part.
it's half of a circle..(we don't really know if the arc is really a circle from the problem but I'm guessing that we are supposed to assume that it is ) and the area of a circle is [tex]\pi[/tex][tex]r^{2}[/tex]
then [tex]\pi[/tex]*[tex]4^{2}[/tex] = 50.2655 which is the entire circle but we only have half.. so divide by 2 = 25.1327 [tex]in^{2}[/tex].
add the 3 parts
93.1327 [tex]in^{2}[/tex].
that's the total area of the "ice cream cone"
now just multiply by 3.1 to find the cost of the flooring

Point B is located at _____.
(-3, 0) (3, 0) (0, 3) (0, -3)
Answer:
3, 0
Step-by-step explanation:
first number is on the horizontal line and the second number on the vertical line
Answer: (3, 0)
Step-by-step explanation: To get to point B from the origin, we move 3 units to the right and 0 units up or down so our point has the coordinates (3, 0).
Remember to always go left or right first, which represents x,
then up or down, which represents y.
