Step-by-step explanation:
The difference between scaled copy and jada drawing is that it is in the ratio
8:4
2:1
that is the scaled copy is twice as large as the jada drawing itself.
So every dimension is doubled or made twice as large as the initial measurement. Andre should not add 4 units to all sides instead the drawing is made twice as large . It will serve the same purpose of enlarging the drawing while maintaining its shape. If extra mesurements are added the drawing will be changed.

A public swimming pool that holds 45,000 gallons of water is going to be drained for maintenance at a rate of 100 gallons per minute. The amount of water w (in gallons) in the pool after t minutes is given by the function w = 45,000 - 100t. Graph the function. Identify its domain and range. How much water is in the pool after 60 minutes? How many minutes will it take to empty the pool?
Answer: for the first question, after an hour there would be 39,000 gallons left and it would take 450 minutes to drain the pool
Step-by-step explanation:
You multiple the minutes with the rate or which the gallons are being drained and subtract it by the total amount,
Ps can I get the brainliest answer
We want to get the domain and range, graph, and analyze the given function.
We have the function:
w(t) = 45,000 - 100*t.
First, we want to get the domain and range of the function.
The domain is defined as the possible values of the input, in this case, is the time.
The smallest value of the time is t = 0, and the largest is the value of t such that the pool is empty, so we need to solve:
w(t) = 0 = 45,000 - 100*t
t = 45,000/100 = 450
Then the domain is D = [0, 450]
The range is the set of the possible outputs, the output represents the amount of water in the pool, it goes from full to empty, so the range is:
R = [0, 45,000]
The graph of the function can be seen below.
How much water is in the pool after 60 minutes?
Just replace t by 60 in the equation.
w(60) = 45,000 - 100*60 = 39,000
This is 39,000 gallons of water.
How many minutes will it take to empty the pool?
We already found that it takes 450 minutes.

If b(x) = negative2(xminus50), what is the value of b(20)?
Answer:
b(20) = 60
Step-by-step explanation:
Here, given that ;
b(x) = -2(x-50)
we want to find the value of b(20)
what we need to do is to simply substitute x for 20
That will be:
b(20) = -2(20-50)
b(20) = -2(-30)
b(20) = 60

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.

The range includes all integers between 0 and 12.5.
The range includes all numbers from 0 to 8.5.
The range includes all numbers from 0 to 12.5.
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".
