Which linear function has the greatest rate of change?​

Answers

The answer is C 252 rate of change

Answer:

D

Step-by-step explanation:

The rate of chnage is the same as the slope.

Slope is x/y. How many y increases/decreases per increase of 1 x

slope for A is

2/500 every 2 x increase, y goes up by 500.

slope for B is

2/500 every 2 x increase, y goes up by 600-100 = 500

slope for C is

1/250

slope for D is

We can write equations by rewriting the important phrases of information using variables. These variables make the equation look neater and it is faster to write a letter instead of constantly repeating 'cost of student tickets', for example.

The important pieces of information lies in the second last sentence of this question.

the tickets of your friend, her mom and her little sister costs a total of $23the tickets of 2 adults and 3 students costs a total of $39

Now, let's rewrite them into equations.

Given

x= cost of adult tickets

y= cost of student tickets

Assuming that your friend and her little sister are students, the two equations are:

x +2y= 23 -----(1)2x +3y= 39 -----(2)

To convert these equations into slope-intercept form, move all the terms that are not y to the right-hand side of the equation before dividing both sides by the coefficient of y. This is to ensure that the coefficient of y is 1 and that your equation is in y= mx +c, where m is the slope and c is the y-intercept.

From equation (1):

x +2y= 23

2y= -x +23

Divide both sides by 2:

[tex]\bf{y = - \frac{1}{2} x + \frac{23}{2} }[/tex]

From equation (2):

2x +3y= 39

3y= -2x +39

Divide both sides by 3:

[tex]\bf{y= - \frac{2}{3} x + 13}[/tex]

The solution to the system of equations is the point at which the two lines intercept on the graph. I have attached the graph as an image.

The solution is (9, 7).

The x coordinate is the cost of an adult ticket, while the y coordinate is the cost of a student ticket. This means that adult tickets cost $9 and student/ child tickets cost $7.

Problem 1

The error happens on the third step. The result should be 47 degrees (approximately). Refer to the steps below to see how I got that value.

[tex]\frac{\sin x}{7} = \frac{\sin 110^{\circ}}{9}\\\\\sin x = \frac{7*\sin 110^{\circ}}{9}\\\\\sin x \approx 0.73087203838903\\\\x \approx \sin^{-1}(0.73087203838903)\\\\x \approx 46.9595500055922^{\circ}\\\\x \approx 47^{\circ}\\\\[/tex]

Make sure your calculator is in degree mode.

If I had to guess where the [tex]m\angle \text{x} = 73^{\circ}[/tex] mistakenly came from, it's probably from the 0.73 shown on step 3, but the student somehow lost the decimal point out front.

==========================================================

Problem 2

The error happens on step 1. The sin(120) should be over top the 35 because the 120 degree angle is opposite the side length of 35.

Similarly, the sin(50) should be over the x

Each fraction involves the angle with its paired opposite side, and vice versa.

Here's one way to write the correct steps to find x.

[tex]\frac{\sin(120)}{35} = \frac{\sin(50)}{x}\\\\x\sin(120) = 35\sin(50)\\\\x = \frac{35\sin(50)}{\sin(120)}\\\\x \approx 30.9593175812171\\\\x \approx 30.96\\\\[/tex]

The equation that represents the linear function for the set of ordered pairs is: A. y = -3x + 2.

What is the Equation of a Linear Function?

Equation of a linear function, where m is the slope and b is the y-intercept, is expressed as y = mx + b.

Find the slope (m):

Slope (m) = change in y/change in x = (-7 -(-4)) / (3 - 2)

Slope (m) = -3/1 = -3

Find b by substituting m = -3 and (1, -1) = (x, y) into y = mx + b:

-1 = -3(1) + b

-1 = -3 + b

-1 + 3 = b

2 = b

b = 2

Substitute m = -3 and b = 2 into y = mx + b

y = -3(x) + 2

y = -3x + 2

Therefore, the equation that represents the linear function for the set of ordered pairs is: A. y = -3x + 2.

exactly 5 liters of punch and include at least three of the juices. Also be sure
to include how many containers of each juice you need. Show your work by
writing equations that show how you determined the capacity.

Answers

Your fruit punch recipe can be composed of 4 juice containers of lemonade, 2 juice containers of orange juice, 2 juice containers of grape juice, 2 juice containers of apple juice, 2 juice containers of cranberry juice, and 2 juice containers of pineapple juice.

Unit conversion

Unit conversion is a tool very useful to solve some questions. For this exercise, you should know that  1 liter (l) = 1000 milliliters (ml).

The question asks you a design your own fruit punch recipe with exactly 5 liters of punch and includes at least three of the juice.

You have several options, an alternative is to use all juices.

Step 1 - Convert the units for each given juice containers

         250 milliliters of lemonade = 0.250 l of lemonade juice

         500 milliliters of orange juice = 0.500 l of orange juice

         250 milliliters of grape juice = 0.250 l of grape juice

         250 milliliters of apple juice= 0.250 l  of apple juice

         500 milliliters of cranberry juice =  0.500 l of cranberry juice

         500 milliliter’s of pineapple juice = 0.500 l of pineapple juice

Step 2 -Design your own fruit punch recipe with  exactly 5 liters

 4 juice containers of lemonade = 4* 0.250 l = 1 l of lemonade

 2 juice containers of orange juice= 2* 0.500 l = 1 l of orange juice

2 juice containers of grape juice= 2* 0.250 l = 0.500 l of grape juice

2 juice containers of apple juice= 2* 0.250 l = 0.500 l of apple juice

 2 juice containers of cranberry juice= 2* 0.500 l = 1 l of cranberry juice

 2 juice containers of  pineapple juice= 2* 0.500 l = 1 l pineapple juice

Thus, your own fruit punch recipe is composed of: 4 juice containers of lemonade, 2 juice containers of orange juice, 2 juice containers of grape juice, 2 juice containers of apple juice, 2 juice containers of cranberry juice, and 2 juice containers of pineapple juice.

What will happen to you and your sister's motion if you push against each other Is; ( A ) You move forward and your sister moves backward at a faster rate.

Meaning of Force and Motion

Force is the product of a mass and an acceleration due to gravity while Motion is a change in position with respect to time.Because you are bigger you will alter her movement by making her go in your direction. you impose more force on here which will make her go faster. But because of that collision, your force will reduce, thereby reucing your speed.

In conclusion the one with the higher mass have the greater force. Therefore What will happen to you and your sister's motion Is that You move forward and your sister moves backward at a faster rate.
