Strictly increasing functions:
Let a function f(a) for x = a, then,
f(a + h), for x = a + h,
If f(a + h) > f(a), we say this a strictly increasing function, as with increase in x, f(x) also increases.
In the given graph, there are straight lines so you can say increasing interval would have +ve slope.
For x = -5 to -4, it increases = [-5, -4]
For x = 1 to 3, it increases = [1, 3]
Answer: [-5, -4] , [1, 3]

First, find the area of both circular sides:
Area = pi x radius^2
Area = pi x (4.5/2)^2
Area = 15.904....
There are two sides, so times the area of the circle by 2.
15.904... x 2 = 31.808....
Afterwards, find the area of the outside circular part.
You use the formula to find the circumference of the circle as that is just the outside length of the circle.
Circumference = pi x diameter
C = pi x 4.5
C = 4.5pi
Afterwards, times the circumference by the 2cm length.
4.5pi x 2 = 9pi
Then, add up all the area.
31.808 + 9pi = 60.082... approx, where this answer is closest to the last answer.

soccer ball inflation:
How many pumps will it take to fill the large soccer ball with a circumference of 71 inches? Recall that the amount of air in one pump was about 11 cubic inches.
must show all work and justify work
Answers
Answer:
549 pumps
Step-by-step explanation:
We'll begin by calculating the radius of the larger ball. This can be obtained as follow:
Circumference (C) = 71
Pi (π) = 3.14
Radius (r) =?
C = 2πr
71 = 2 × 3.14 × r
71 = 6.28 × r
Divide both side by 6.28
r = 71 / 6.28
r = 11.3 in
Next, we shall determine the volume of the larger ball.
Since a ball is spherical in shape, we shall use the formula for calculating the volume of a sphere to obtain the volume of the ball. This can be obtained as follow:
Pi (π) = 3.14
Radius (r) = 11.3 in
Volume (V) =?
V = 4/3πr³
V = 4/3 × 3.14 × 11.3³
V = 4/3 × 3.14 × 1442.897
V = 6041 in³
Finally, we shall determine the number of pumps will it take to fill the large soccer ball. This can be obtained as follow:
11 in³ = 1 pump
Therefore,
6041 in³ = 6041 in³ × 1 pump / 11 in³
6041 in³ = 549 pumps
Thus, it will take approximately 549 pumps of air to fill the large soccer ball.
Select the correct answer from each drop-down menu. Javier purchased a digital camera for $384. The value of the camera depreciates by 25% every year. This situation represents . The rate of growth or decay, r, is equal to . So the value of the camera each year is times the value in the previous year. It will take years for the value of the camera to reach $162.
Answers
Answer:
it will take 3 yrs for the value of camera to reach $162.
Step-by-step explanation:
Pd = P(1-R/100)^T
162 = 384(1-25/100)^T
162/384 = (3/4)^T
27/64 = (3/4)^T
(3/4)^3 = (3/4)^T
T = 3
Answer:
this represents: exopnential decay, the rate of growth or decay is equal to: 0.25, value of the camera each year is: 0.75, it will take 3 years.

12x + 32 = 4
Answers
Given:
The equation is:
[tex]x^2-12x+32=4[/tex]
To find:
The result of completing the square for the given equation.
Solution:
We have,
[tex]x^2-12x+32=4[/tex]
It can be written as:
[tex]x^2-12x=4-32[/tex]
[tex]x^2-12x=-28[/tex]
Now, we need to add half of square of coefficient of x, to complete the square.
Adding [tex](\dfrac{-12}{2})^2[/tex] on both sides, we get
[tex]x^2-12x+(\dfrac{-12}{2})^2=-28+(\dfrac{-12}{2})^2[/tex]
[tex]x^2-2(x)(6)+(-6)^2=-28+(-6)^2[/tex]
[tex]x^2-2(x)(6)+(6)^2=-28+36[/tex] [tex][\because (-a)^2=(a)^2][/tex]
Using the formula [tex](a-b)^2=a^2-2ab+b^2[/tex], we get
[tex](x-6)^2=8[/tex]
Therefore, the required equation after completing the square is [tex](x-6)^2=8[/tex].

You haft too use elimination to solve this thank you
Answers
Answer:
x=0, y=-2
Step-by-step explanation:
Because 9y appears twice in both equations, you can subtract the equations to eliminate the y variable so you can solve for x:
-7x + 9y = -18
-(4x + 9y = -18)
__________
-11x = 0
x = 0
Since we know x=0, then we plug it back into one of the equations to get the value of y:
-7x + 9y = -18
-7(0) + 9y = -18
0 + 9y = -18
9y = -18
y = -2
Therefore, x=0, and y=-2
