Can someone please help ASAP An online video store charges a monthly fee of $10, plus $2 for each video rental. Which graph below best
represents the relationship between the number of video rentals and the total monthly cost?
Using linear function concepts, it is found that graph A is the one that best represents the relationship.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, there is a fixed fee of $10, plus a fee of $2 per movie, hence m = 2, b = 10, and the function is given by:
y = 2x + 10.
Due to the y-intercept of y = 10, that is, when x = 0, y = 10, graph A is the one that best represents the relationship.

Find BC in angle ABC
Round to the nearest tenth.
BC=?
Answer:
BC ≈ 18.7
Step-by-step explanation:
using the sine rule in Δ ABC
[tex]\frac{BC}{sinA}[/tex] = [tex]\frac{AC}{sinB}[/tex] ( substitute values )
[tex]\frac{BC}{sin67}[/tex] = [tex]\frac{20}{sin80}[/tex] ( cross- multiply )
BC × sin80° = 20 × sin67° ( divide both sides by sin80° )
BC = [tex]\frac{20sin67}{sin80}[/tex] ≈ 18.7 ( to the nearest tenth )

Find the length of the segment with endpoints at (2, 7) and (8, -1). using the formula below.
Answer:
10
Step-by-step explanation:
Let (2, 7) = [tex](x_{1} ,y_{1} )[/tex] and (8, -1) = [tex](x_{2} ,y_{2} )[/tex]
= [tex]\sqrt{(8-2)^{2} + (-1 -7)^2}[/tex]
= [tex]\sqrt{6^2 +(-8^2)}[/tex]
= [tex]\sqrt{36 + 64}[/tex]
= [tex]\sqrt{100}[/tex]
= 10
The length of the segment with endpoints at (2, 7) and (8, -1) using distance formula is 10 units.
Distance formula is the the formula for calculating the length of a line segment given the coordinates of the endpoints. The formula is given as :
Given the endpoints [tex](x_1,y_1), (x_2, y_2)[/tex]
d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Given in the question,
[tex](x_1,y_1) = (2,7)\\(x_2, y_2)=(8,-1)[/tex]
[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\d= \sqrt{(8-2)^2+(-1-7)^2}\\\\d= \sqrt{(6)^2+(-8)^2}\\\\d = \sqrt{36+64} = \sqrt{100} = 10[/tex]

Cohen mailed a letter on Monday morning. The letter has to travel 12 1/2 miles to reach it's destination.
The letter traveled 2 1/4 miles on Monday and traveled an additional 7 1/12 miles on Tuesday.
How far did the letter travel on Wednesday to reach it's destination?
Answer:
2 3/4 miles
Step-by-step explanation:
Remaining miles are found by subtracting miles already traveled from the number that need to be traveled.
__
12 1/2 - 2 1/4 - 7 1/2
= (12 1/2 -7 1/2) -2 1/4
= 5 -2 1/4 = 2 3/4
The letter traveled 2 3/4 miles on Wednesday to reach its destination.

Both the median and the range changed, the correct option is A.
What is the median?Median, in statistics, is the middle value of the given list of data, when arranged in an order.
The data set that contains the outlier is given as:
4, 14, 15, 15, 16, 16, 18, 19, 20, 20, 21
The minimum value of the data is: 4
The median or middle quartile i.e. [tex]\rm Q_2[/tex] is the central tendency of the data and exists in the middle of the data.
The median is: 16
Also, the lower set of data is:
4,14,15,15,16
The lower quartile i.e. [tex]\rm Q_1[/tex] is the median of the lower set of data.
The lower quartile i.e. [tex]\rm Q_1[/tex] = 15
Similarly, the upper set of data is:
18, 19, 20, 20, 21
the upper quartile i.e. [tex]\rm Q_3[/tex] is the median of the upper set of data.
upper quartile i.e. [tex]\rm Q_3[/tex] = 20
Also, the interquartile range is:
[tex]\rm Q_3-Q_1=20-15=5[/tex]
The maximum value of the set is 21.
Range = Maximum value-Minimum value =21 - 4 = 17
As we know that 4 is the outlier of the data as it is the smallest as compared to all the data points.
After removing the outlier the data set is:
14, 15, 15, 16, 16, 18, 19, 20, 20, 21
The minimum value of the set =14
The maximum value of set =21
Range = Maximum value-Minimum value =21-14 = 7
Hence, Both the median and the range changed.

[tex]\qquad \tt \dashrightarrow \: \angle1 = 90 \degree[/tex]
So, D is the correct choice ~
Step-by-step explanation:
As the sum of all angles of triangle is 180°
and we have been given 2 angles i.e 30° and 60°
So, Third angle will be 90°
Angle 1 = 180°-90° (as the value of angle made by a straight line is 180°)
