Which statement best illustrates using the vertical line test to determine if the graph below is a function of x? The graph is not a function of x because the line x = 0 intersects the graph at two points. The graph is a function of x because the line x = 5 does not intersect the graph. The graph is not a function of x because the line y = 0 intersects the graph at two points. The graph is a function of x because the line y = 5 does not intersect the graph.

Answers

Answer:

The graph is not a function of x because the line x = 0 intersects the graph at two points.

Step-by-step explanation:

This graph is not a function because it fails the vertical line test, since several vertical lines would intersect the graph at 2 points.

This answer choice is correct, as the line x = 0 intersects the graph at 2 points, (0, 2) and (0, -2).

if 11,100 is invested at 3.1 percent interest compounded monthly, how much will the investment be worth in 19 years?

Answers

The formula for compound interest is:
A=P(1+r/n)^(nt)
Where A represents the amount of money in the account after t years, P is the principal (investment), n is the number of compoundings per year, and r is the interest rate in decimal form.
P=11,100
r=.031
n=12 (monthly)
t=19
A=11,100(1+.031/12)^(12*19)
A=11,100(1+. 002583)^(228)
A=11,100(1.002583)^(228)
A=11,100(1.80082)
A=$19,989.10

The perimeter of a square is 48 centimeters. What is its area?

Answers

the area is 144 units.

area is length × width

squares have an equal lenght and width, and 4 sides. if a square's perimeter is 48, we need to divide that by 4 to get the size of each side.

48 ÷ 4 = 12

each side is 12 units. to get the area, we need to mutliple length × width, in this case 12 × 12, which equals 144 units.

Each side would equal 12 centimeters then, and the way to find the area is by multiplying the height and width. So, the area would be 144 centimeters!
I hope this helps!! :)
P.S. When finding the area of a triangle always remember after multiplying the 2 numbers together you have to divide by 2.

Irina predicted that she would sell 75 books, but she actually sold 95 books. Which expression would find the percent error? Use the table below to help answer the question.

Answers

There is no image of the table given.

Given:
approximate number = 75
exact number = 95

error = |approximate number - exact number| ÷ exact number
error = |(75-95)| / 95 = |20| / 95 = 0.21

percentage of error = 0.21 x 100% = 21%

Answer:

Given:

approximate number = 75

exact number = 95

error = |approximate number - exact number| ÷ exact number

error = |(75-95)| / 95 = |20| / 95 = 0.21

percentage of error = 0.21 x 100% = 21%
