Y – x² = 4.5 and y = x^4 Is this function linear or non linear?

Also show work and explain why.

Answers

Answer 1
Answer: Linear functions are in the form y=mx+b.

But the functions are in the form of y=x^4 and y-x^2=4.5.
Their exponents make them a quadratic function so it doesn't have the same rate of change. Therefore the equations are not linear. They are quadratic.
Answer 2
Answer: Linear functions are in the form of y = mx + b.

y - x² = 4.5 is not linear because of the x².

y = x⁴ is not linear because of x⁴.

a cylindrical water tower is 24 feet high and has a diameter of 20 feet. approximately how many cubic feet if water could the tower hold? (answers above^^)

Answers

Answer:

Helloo.

Step-by-step explanation:

Because this question is asking how much water the water tower can hold, it's asking for the volume of a cylindrical figure. Let's use this formula:

V

=  

π

r

2

h

First, let's find our variables by plugging in our information.

r

=  

(

1

2

)

d

 

r

=  

(

)

20

r

=  

10

h

=  

24

V

=  

π

(

)

(

24

)

Following PEMDAS (Parentheses, Exponents, Multiply, Divide, Add, Subtract), we'll find  

(

)

first.

V

=  

π

(

100

)

(

24

)

 

Now, multiply (100) and (24):

V

=  

π

(

2400

)

 

V

=

Plz help me on number 23

Answers

Well first of, 1/6 is not 15%, 1/6 is actually 16.6666666%. You want the fraction 3/20.
To add the first row we need to find a common denominator, which is 20. The new fractions become (5/20)+(12/20)+(3/20) which sums to 20/20 or 1.
the second row is 25+60+15=100%
the third row is 0.25+.60+.15=1
All of these answers add to a whole, in this case the total budget Evan decided on.
