Please help me:<br><br>What's the domain?<br><br>What's the range?<br><br>Is it a function?​
VladimirAG [237]

Answer:

\displaystyle Yes \\ Range: Set-Builder\:Notation → [f(x)|-2 ≤ f(x) ≤ 4] \\ Interval\:Notation → [-2, 4] \\ \\ Domain: Set-Builder\:Notation → [x|0 ≤ x ≤ 7] \\ Interval\:Notation → [0, 7]

Step-by-step explanation:

Just by looking at the graph vertically and horisontally, you can tell what the range and domain is, depending on whether the segments are <em>closed</em> or <em>opened</em>.

* This is a function because it passes the <em>vertical</em><em> </em><em>line test</em>.

** This is kind of like a sine wave.

I am joyous to assist you anytime.

Jack bought 50 lbs of clay for his art projects. He used 13.2 lbs to make a sculpture, and 0.72 lbs for each mug. How many mugs
KIM [24]

Given :

Jack bought 50 lbs of clay for his art projects. He used 13.2 lbs to make a sculpture, and 0.72 lbs for each mug.

To Find :

How many mugs did Jack make if he had 28.88 lbs of clay left over.

Solution :

Clay required to make 1 mug, r = 0.72 lbs.

Amount of clay left after making sculpture is, T = 28.88 lbs.

Now, number of clay mug Jack can make is :

n = \dfrac{28.88}{0.72}\\\\n= 40.11

Since, number of mug cannot be in decimal, so we take the floor value.

Therefore, number of mug that can be prepared is 40 .

A rectangular picture frame has a length of that is 6 more than its width the perimeter of the frame is 52 inches. what is the l
Hitman42 [59]

Answer:

Width = 10 and Length = 16

Step-by-step explanation:

→ Assign variables to the length and width

width = x so length = 6 + x

→ Make an equation

x + 6 + x + x + 6 + x = 52

→ Simplify

4x + 12 = 52

→ Minus 12 from both sides

4x = 40

→ Divide both sides by 10

x = 10

→ Resubstitute into the previously assigned values

width = 10 so length = 16
