What is the equation for the graph on question 1

Answers

Answer 1

Answer: f(x) = x^2 - 4*x

Step-by-step explanation:

This is a quadratic equation, that can be written in factorized form as:

f(x) = A*(x - a)*(x - b)

Where A is a real number, a and b are the roots of the equation.

In the graph we can see that the graph intersects the x-axis at x = 0, and x = 4, then:

a = 0

b = 4

So the equation is:

f(x) = A*(x -0)*(x - 4) = A*x*(x - 4)

Now we can also see that, the arms of the exponential open up, this means that A is positive, and we also can see that f(2) = -4

Then:

f(2) = A*2*(2 - 4) = -4

= A*2*(-2) = -4

= A*-4 = -4

A = -4/-4 = 1

A = 1

Then the equation is:

f(x) = x*(x - 4) = x^2 - 4*x

Answer:

shape: rectangle27.5 square inches1 1/8 inches by 1 2/3 inchessee attached

Step-by-step explanation:

The drawing scale is ...

1/4" : 1 ft = 1/4" : 12" = 1 : 48

1) The bedroom shape has two pairs of parallel sides and right-angle corners. It is a rectangle.

2) The area of the drawing is 20(1/4 in) × (22(1/4 in)) = 440(1/16 in²)

= 27.5 square inches . . . . area of the bedroom on the drawing

3) The drawing side of the bed is 1/48 of the bed's actual dimensions, so is ...

54/48 in × 80/48 in = 1 1/8 in × 1 2/3 in . . . . size of the bed on the drawing

4) The drawing looks like it may have been made on a 1/4" grid, but there are only 17 grid squares along the side labeled 20 (feet). So, we actually have no good reference for size. Using the dimension marked as 3 feet for reference we estimated the bed size, trying for 4 1/2 by 6 2/3 feet.

When we print the figure to a piece of paper, we have to scale it to 88.1% to make the 20-foot dimension come out 5 inches. Doing that shows our bed outline is about 82 inches long, not 80 inches long. YMMV

WHOEVER ANSWERS IS CONSIDERED THE BRAINLIEST QUESTION: Faye has a bag that contains 10 red, 13 blue, 16 white, 10 green, and 11 black marbles. She pulls a marble out of the bag without looking. What is the probability Faye pulls out a white marble.
SHOW WORK!

Answers

Answer:

Faye's probability of pulling out a white marble is 3/80.

Step-by-step explanation:

To find the probability, we must first add everything up. 10 + 13 + 16 + 10 + 11 = 60 marbles. Now we divide 60 by the amount of white marbles there are. 60 ÷ 16 = 3.75% or 3/80. Therefore, the probability of Faye pulling out a white marble is 3/80.

Answers

Cindy got a 100

(100-84)/7.35=2.2

D FINAL ANSWER

Based on the test scores of the students, Cindy's z-score on the science test is 2.2

How to determine the z-score of Cindy?

We start by calculating the mean of the scores using:

Mean =Sum/Count

So, we have:

Mean = (75 + 80 + 90 + 100 + 75 + 85 + 80 + 80 + 90 + 85)/10

Mean = 84

Using a statistical calculator, the standard deviation is:

Standard deviation = 7.35

The z-score is then calculated using:

z = (x - mean)/standard deviation

Cindy's score is 100.

So, we have:

z = (100 - 84)/7.35

Evaluate

z = 2.2

Hence, Cindy's z-score on the science test is 2.2

A newspaper and magazine cost 220 together the newspaper cost 140 less than the magazine find the cost of each

Answers

Answer: $40- Newspaper $180- Magazine
Explanation: Subtract 140 from 220 then divide by 2. When you divide by 2 you’ll get the answer for the newspaper and then just add the remaining to the total you divided by.

A newspaper and magazine cost 220 together the newspaper cost 140 less than the magazine, then the cost of magazine is 180 and the cost of newspaper is 40.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given,

A newspaper and magazine cost 220

the newspaper cost is 140 less than the magazine

Let x be the cost of magazine

x-140 is the cost of newspaper

x+x-140=220

2x-140=220

Add 140 on both the sides

2x=220+140

2x=360

Divide both sides by 2

x=180

and x-140=180-140=40

Hence, the cost of magazine is 180 and the cost of newspaper is 40.

The firm has been stable in size for the last 20 years, ignoring growth opportunities in the 90s, but also not suffering from a need to down-size in the recession. Specifically, there have been and are expected to be 200 associates, 60 managers, and 20 partners. The work environment at Mt Kinley is rather competitive. After 4 years of working as an associate, a consultant goes "either up or out", i.e. becomes a manager or is dismissed from the company. Similarly, after 6 years a manager either becomes a partner or is dismissed. The company recruits MBAs as associate consultants, no hires are made at the manager or partner level. A partner stays with the company for another 10 years (total of 20 years with the company). How many new MBA graduates does Mt Kinley have to hire every year?
