How many points need to be removed from this graph so that will be a function?

Answers

Answer 1

4 , might be wrong that’s what I think tho

Answer 2

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

The answer is you have to remove 4 points.

There is 6 points in all and for a function it only needs two points to become a function. A function needs to be a that line that passes the vertical line test. For example: A circle is not a function because when you perform the vertical line test you'll see that many points share a common x-value and a function needs only one output in every input.

Use a calculator to find the approximate value of the expression. Round the answer to two decimal places.
The cosine of the complimentary angle to 38°
a. 0.68
b. -0.16
C. -0.22
d. 0.62

Answers

Answer:

The cosine of the complementary angle to 38° is 0.62. Answer: d

Explanation:

Complementary Angle

Two angles x and y are complementary if

x+y=90°

The complementary angle of 38° is 90°-38°= 52°

Now use a calculator to find the approximate value of

[tex]\cos 52^\circ \approx 0.61566[/tex]

Rounding to two decimal places:

[tex]\cos 52^\circ \approx 0.62[/tex]

a. Incorrect. The cosine of 52° is not 0.68

b. Incorrect. The cosine of 52° is not -0.16

c. Incorrect. The cosine of 52° is not -0.22

d. Correct. The cosine of 52° is 0.62 to two decimal places.

Raleigh went to a gaming arcade for his birthday. His parents gave him $55 to spend. He purchased $14.25 in food and drinks, and put the rest of the money on a gaming card to spend at the arcade. Each game cost $1.25. Choose which inequality represents how many games "g" he can play.

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Total amount to spend = $55

Amount of food and drinks purchased = $14.25

Amount put on gaming card = $(55 - 14.25) = $40.75

Cost per game = $1.25

Number of games (g) he can play

Number of games g:

Amount put on gaming card / cost per game

= $40.75 / $1.25

= 32.6 games

g ≤ 32

If y = 12 when x = –15, find y when x = 2.

Answers

Answer:

Step-by-step explanation:

First make an equation that shows the relationship between x and y by finding what you need to do to x to get y:

-15 + ? = 12

? = 27

so the equation is : y = x + 27

now just plug in 2 for x:

y = 2 + 27

y + 29

The function represented in the table is a linear function given by y = (1/4)x + 80

What is an equation?

An equation is an expression that shows the relationship between two or more number and variables.

Let y represent the pressure of the gas at x temperature.

Using the point (44, 91) and (52, 93), hence:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-91=\frac{93-91}{52-44} (x-44)\\\\y=\frac{1}{4} x+80[/tex]

The function represented in the table is a linear function given by y = (1/4)x + 80
