Answer:

y=1x+2

Step-by-step explanation:

Which expression could be used to determine the cost of a $50 video game after a 20 percent discount?
50 dollars (0.20)
50 dollars minus left-bracket (50 dollars) (0.08) right-bracket
50 dollars minus 0.80
50 dollars (0.80). please a b c or d?

Answers

Answer:

d

Step-by-step explanation:

to find a discount you would multiply 50(0.20) whatever amount you get you would subtract that from 50

this is the same as 50(0.80)

I’m pretty sure it’s d, because 50 (0.80) = 50 x 0.80 which equals 40 which is the 20% discount off of 50

An airplane flies across the country. Its distance from Portland, as a function of time, is modeled by y. 500x.

Which statement best describes the function?

A. The function is nonlinear

B. The function is linear at some points and nonlinear at other points.

c. The function is linear

D. Not enough information is given to decide​

Answers

Answer:

I would say b

Step-by-step explanation:

I choose b because the question is linear and also non linear it only told us the distance which is 500x and no time but is saying as a function of time

C. The function is linear.

The given function is y = 500x, where x represents the time and y represents the distance from Portland. In this function, y is directly proportional to x, meaning that for every unit increase in x, y increases by a constant amount of 500.

Since the function is of the form y = mx, where m (in this case, 500) is the constant of proportionality, the function is linear.

Therefore, the correct answer is:

C. The function is linear.

What is the value of tan A?
8/17
15/8
8/15
15/17

Answers

Answer:

B) 15/8

Step-by-step explanation:

Use the SOH-CAH-TOA acronym:

• SOH: Sin(θ) = Opposite / Hypotenuse

• CAH: Cos(θ) = Adjacent / Hypotenuse

• TOA: Tan(θ) = Opposite / Adjacent

Tangent of A would be "opposite" over "adjacent". The side of the triangle opposite angle A would be 15, and the side adjacent to angle A would be 8 -- the value of tan(A) is 15/8.

Tan(A) cannot be 15/7, because 7 is the hypotenuse. Remember that the hypotenuse of a right triangle is the side opposite the 90° angle -- here, angle B is the 90° angle.

There are 100 tiles that were purchased to raise money for a new playground. The tiles will be laid along a walkway. Each tile is 4.75 inches wide. If the tiles are going to all be lined next to each other, how many inches long will they cover along the walkway? A. 0.475 inch B. 47.5 inches C. 475 inches D. 4,750 inches

Answers

Answer:

C. 475 inches

Step-by-step explanation:

Step one:

given

the number of tiles is 100 in total

the dimension of the tiles is 4.75 inches wide

Step two:

Required

We want to find the length that 100 tiles will cover

Hence the length will be 4.75*100

=475inches

={(a+b) (a+b)} (a+b)

={a(a+b) + b(a+b)} (a+b)

=(a^2 + ab + ab + b^2) (a+b)

=(a^2 + b^2 + 2ab) (a+b)

=a^2(a+b) + b^2(a+b) + 2ab(a+b)

=a^3 + a^2b + ab^2 + b^3 + 2a^2b + 2ab^2

=a^3 + b^3 + 3a^2b + 3ab^2

=a^3 + b^3 + 3ab(a+b)

(a+b)^3 = a^3 + b^3 + 3ab(a+b)

(a+b)^3 - 3ab(a+b) = a^3 + b^3

a^3 + b^3 = (a+b)^3 - 3ab(a+b)

Step-by-step explanation:

Here, given that ;

we want to find the value of b(20)

Required

How many more books did Joe read.

First, we need to determine number of books Craig reads

If in a week, Craig reads 3 books

Then in 3 weeks, Craig reads 3 * 3 books

Next, we need to determine number of books Joe reads

If in a week, Joe reads 3 books

Then in 4 weeks, Joe reads 4 * 3 books

Next, we determine the difference;

Answers

Answer:

The range includes all numbers from 5 to 12.5.

Step-by-step explanation:

The range is along y- axis and the domain is along x- axis.

Range is given in heights and domain is given in time seconds.

It can depicted that for t= 0 secs the ball is at 5 feet and so on .

Therefore the range is given by numbers from 5 to 12.5.

Whereas the domain is given by numbers 0 t0 8.5 seconds

The range is the values of 'y' and the domain is the values of 'x'. So, the range of the includes all numbers between 5 and 12.5 and the domain includes all numbers between 0 and 8.5.

Given :

A child tosses a baseball up into the air. On its way down, it gets caught in a tree for several seconds before falling back down to the ground.

The graph attached below shows the given scenario that "A child tosses a baseball up into the air. On its way down, it gets caught in a tree for several seconds before falling back down to the ground".

The y-axis shows the height of the ball in feet from the ground and the x-axis shows the time in seconds.

The range is the values of 'y' and the domain is the values of 'x'. So, the range of the includes all numbers between 5 and 12.5 and the domain includes all numbers between 0 and 8.5.

Therefore, the correct option is A) The range includes all numbers from 5 to 12.5.

What is a function?

A statement, principle, or policy that creates the link between two variables is known as a function.

Monthly private school tuition based on the average number of weeks in attendance is predicted using the least-square regression line.

y = 265.9 + 93.4x, where y represents the predicted monthly expense and x represents the average number of weeks in attendance.

A child attends private school an average of 3.5 weeks and has a monthly cost of $595.

Then the residual for the child will be

⇒ 595 – (265.9 + 93.4 × 3.5)

⇒ 595 – (592.8)

⇒ 2.2

Then the correct option is B.

Use evidence from the letter to support your answer."I will now add what I do not like.

To say, as Mr. Wilson does that a bill of rights was not necessary because all is reserved in the case of the general government which is not given, while in the particular ones all is given which is not reserved, might do for the audience to whom it was addressed, but is surely a gratis dictum, opposed by strong inferences from the body of the instrument, as well as from the omission of the clause of our present confederation which had declared that in express terms. It was a hard conclusion to say because there has been no uniformity among the states as to the cases triable by jury, because some have been so incautious as to abandon this mode of trial, therefore the more prudent states shall be reduced to the same level of calamity.
