In a linear function, the rate of change is constant.
A linear function is also of the first degree.
Item 1:
From -3 to -1, the rate of change is of
From -1 to 1, the rate of change is of .
Different rates of change, so non-linear.
Item 2:
At function b, from 0 to 1, the rate of change is of 1, from 1 to 2 of 3, different rates of change, so non-linear.
Item 3:
Highest degree of x is 1, so first degree, and thus linear.
Item 4:
The only non-linear is , which is of the second degree.

The area of circle 1 is 6 square units. The area of circle 2 is 7 square units. Which of the following is true about the circumferences of the circles? A. The circumference of circle 1 equals the circumference of circle 2. B. Not enough information is given to make a comparison between the circumferences of the circles. C. The circumference of circle 1 is less than the circumference of circle 2. D. The circumference of circle 1 is greater than the circumference of circle 2.
Answer:
C. The circumference of circle 1 is less than the circumference of circle 2.
Step-by-step explanation:
6<7
We know that the formula for the area of a circle is πr². This means the greater the radius, the greater the area.
We also know that the formula for circumference is 2πr. It is also dependent on radius. The greater the radius, the greater the circumference.
Given that Circle 2 has a greater area, this means that it has a greater radius which in turn means that it has a greater circumference.
C. The circumference of circle 1 is less than the circumference of circle 2.
Answer:
The circumference of circle 1 is less than the circumference of circle 2.
Step-by-step explanation:
Hi there!
When we compare two circles, if one is bigger than the other, it must have a greater circumference. We can see this visually.
If we want to prove this, we can take a look at the area and circumference formulas (r = radius):
[tex]A=\pi r^2[/tex]
[tex]C=2\pi r[/tex]
If we were to substitute the area formula into the formula for circumference, we would get the following:
[tex]\displaystyle\frac{A}{\pi}=r^2\\\\\sqrt{\displaystyle\frac{A}{\pi}}=r[/tex]
[tex]C=2\pi (\sqrt{\displaystyle\frac{A}{\pi}})[/tex]
Therefore, the greater the area of a circle, the greater its circumference.
I hope this helps!

A circle has a center (2, 4). prove that if the radius of the circle is less than 5, then the circle does not intersect the line y=x-6.
Answer:
the distance from the center to the line is about 5.65, too far from a circle of radius 5.
Step-by-step explanation:
We can prove this by looking at the distance from the center of the circle to the line.
The distance from point (x, y) to line ax+by+c=0 is given by ...
d = |ax +by +c|/√(a^2 +b^2)
For the line ...
x -y -6 = 0
and the point (2, 4), the distance is ...
d = |2 -4 -6|/(1^2 +(-1)^2) = |-8|/√2 = 8/√2 ≈ 5.65685
This tells us that a circle with radius 5.65 or less will not intersect the line. A circle of radius 5 is smaller than that. A circle with radius 5 will not intersect the line y = x-6.

The length of a towel is 75 centimeters.
How long is the towel in inches?
Round to the nearest hundredth, if necessary.
Answer:
it's 29,53 inches (after rounding off)
Step-by-step explanation:
as far as I can remember I said
75 × 0.393701 (this is 1 inch)
= 29,527575
= 29,53
The length of towel after converting in inches from centimeters will be 29.55 inches.
What is Measurement unit?
A measurement unit is a standard quality used to express a physical quantity.
Given that;
The length of a towel in centimeters is;
⇒ 75 centimeters.
Now,
Since, we know that;
⇒ 1 centimeter = 0.394 inches.
So, We convert the length of a tower from centimeter to inches as;
⇒ 1 centimeter = 0.394 inches.
⇒ 75 centimeter = 75 x 0.394 inches.
After multiplication, we get;
⇒ 75 centimeter = 29.55 inches.
Since, the length of a towel in already round to the nearest hundredth.
Hence, 75 centimeter = 29.55 inches.
Therefore,
The length of towel after converting in inches from centimeters will be 29.55 inches.

If the total revenue function for a blender is R(x) = 56x − 0.01x2 where x is the number of units sold, what is the average rate of change in revenue R(x) as x increases from 11 to 22 units? $ per unit g
The revenue function is the sum of the profit and cost functions
The average rate of the revenue is 55.67
How to determine the average rate of changeThe revenue function is given as:
[tex]R(x) = 56x - 0.01x^2[/tex]
The interval is given as:
(a,b) =(11,22)
The average rate of change over the interval (a,b) is calculated as:
[tex]R'(x) =\frac{R(b) - R(a)}{b -a}[/tex]
This gives
[tex]R'(x) =\frac{R(22) - R(11)}{22 -11}[/tex]
[tex]R'(x) =\frac{R(22) - R(11)}{11}[/tex]
Calculate R(22) and R(11)
[tex]R(22) = 56*22 - 0.01*22^2[/tex]
[tex]R(22) = 1227.16[/tex]
[tex]R(11) = 56*11 - 0.01*11^2[/tex]
[tex]R(11) = 614.79[/tex]
So, we have:
[tex]R'(x) =\frac{R(22) - R(11)}{11}[/tex]
[tex]R'(x) =\frac{1227.16 - 614.79}{11}[/tex]
[tex]R'(x) =\frac{612.37}{11}[/tex]
Evaluate the quotient
[tex]R'(x) =55.67[/tex]
Hence, the average rate of the revenue is 55.67

Estimate square root of 12 to the nearest tenth.
A 4.5
B 3.9
C 4.1
D 3.5
Answer:
3.5
Step-by-step explanation:
As a first approximation of the square root, you can look at the integers relating the given number to the next lower square number. The next lower square number is 3^2 = 9.
12 = n^2 +r = 3^2 +3 . . . . . n = 3, r = 3
The approximate square root is ...
n +r/(2n+1) = 3 +3/7 ≈ 3.429
This value tends to be a little low. Alternatively, the root can be estimated as ...
n +r/(2n) = 3 +3/6 = 3.5
This value tends to be a little high.
A reasonable estimate of √12 is 3.5.
__
Of course, your calculator can tell you instantly that the root is about 3.464102, close to 3.5.
_____
Additional comment
The relation we used above simplifies the work of linear interpolation between the points (9, 3) and (16, 4) on the square root curve. For some n between 9 and 16, the interpolated root value r would be found from ...
(n -9)/(16 -9) = (r -3)/(4 -3)
(n -9)/7 = (r -3)/1
r = 3 +(n -9)/7 = 3 +(12 -9)/7 = 3 +3/7 . . . . as above
Note that "r" is used for "root" in this discussion. In the above answer, "r" is used for "remainder."
