The data in the table represents a company's profit based on the number of items produced.Which equation best represents the data?

A) y= -1.026x^2 + 1016.402x - 162075

B) y= -1.036x^2 + 1024.771x - 163710

C) y= 298.214x - 66317.667

D) y= 196.2x - 18710

Answers

Answer 1

Answer:

Answer:

(A) y= -1.026x^2 + 1016.402x - 162075

Step-by-step explanation:

Given is the data 'x' -Items produced. The equation that satisfies the given data can be found by simply substituting the values of x in the given equations. For example:

Substituting the value of x= 100 in the given equations,

A) y= -1.026(100)^2 + 1016.402(100)-162075= -70,500

Similarly you can check the values on the rest of the equations and if they satisfy the equation, then the given is the required equation.

Answer 2

Answer:

Answer:

(A)

Step-by-step explanation:

WE are given the data which represents the company's profit based on number of items produced.

The equation which best represents the data can be found out by substituting the values of x in the given equations.

So,substituting x=100 in first equation, we have:

$y=-1.026x^(2) +1016.402x-162075$

$y=-1.026(100^(2))+1016.402(100)-162075$

$y=-10260+101640.2-162075$

$y=-70500$

which satisfies the equation. Hence, option A satisfies.

We can also substitute the different values of x in the equations to check whether it satisfies or not.

URGENT!!! HELPGina has purchased 100 songs from the internet. She plans to download an equal number of songs on her music player each week for 5 weeks. The graph shows the number of songs left to download, y, for a certain number of weeks, x:

(Graph attached below)

Part A: What is the rate of change and initial value of the function represented by the graph, and what do they represent in this scenario? Show your work to find the rate of change and initial value. (6 points)

Part B: Write an equation in slope-intercept form to model the relationship between x and y. (4 points)

Answers

Answer:

Initial value is 100

Step-by-step explanation:

A) rate of change would be dividing the number of songs wanted (100) by the number of weeks downloading (5)

100/5 = 20

since the total quantity wanted is becoming less every week the rate of change would be negative so it becomes -20

Initial value is 100, which is the total number of songs they want

Answer:

Part A:

initial value = 100 (total amount of songs to download)

rate of change = -20 songs/week (100-80 and so on)

Part B:

y = -20x + 100

What is 3/4 of a 2 liter bottle in millimeters

Answers

I believe you meant milliliters. If so the answer is 1500ml

2 liters = 2000ml

2000/4 = 500 for 1/4

We need 3/4 so we multiply 500 X 3 and get 1500ml

If there are 1000 mL in one L we have 1000 plus half is 500 and half of that is 250 which means that 3/4 is 750 add to get 1750 mL

In the figure, the measure of angle 7 is 57°. What is the measure of angle 8?

Answers

Answer: The measure of angle 8 is 123° .

Step-by-step explanation:

Since we have given that

m∠7 = 57°

we have two lines intersecting each other at one point forming angles ∠7, ∠8, ∠5, ∠6.

So, Relation between ∠7 and ∠8 is linear pair.

And we know that ,

$\angle 7+\angle 8=180\textdegree\n\n57\textdegree+\angle 8=180\textdegree\n\n\angle 8=180\textdegree-57\textdegree\n\n\angle 8=123\textdegree$

Hence, the measure of angle 8 is 123° .

Angle (6) + Angle (7) = 180

Angle (6) + 57 = 180

Angle (6) = 180 - 57

Angle (6) = 123

------------

Angle (6) = Angle (8)

-----------

Therefore:

Angle (8) = 123 degrees

How do u decomposition 1 1/4

Answers

It is 5/4 if you want it in an improper fraction.
So the rule is multiply down low and add up high.
If you know what 1 (the whole number) times 4 (the denominator) will equal 4
Then add the 1 to the four that will equal 5 with the same denominator which is 4
The answer is 5/4
If that is what you asked

If you would like and improper fraction it would be 5/4
