Answer:
The domain for this function is all real numbers greater than -2.
There will be 4 floats in a parade. the parade organizers are trying to determine the order in which the floats should appear. how many different orders are possible?
Using permutation, there are a total of 24 different orders possible.
If there are a total of 4 floats in a parade then the number of possible orders = 4!
If we further calculate it we will get,
4 x 3 x 2 x 1 = 24
So there are a total of 24 possible orders in which the floats should appear.
The concept used here is the number of arrangements and the technical term used for it in mathematics is a permutation. A permutation is a mathematical calculation that involves finding the number of ways a particular set can be arranged.

The radius of a sphere is 14 cm. The cost of
painting the surface of sphere is ₹25 per
square cm. If the radius of sphere is increased
by 10%, then the cost of painting is increased
by 20%. What is the percentage increase in
the total cost of painting per square cm?
(a) 54.27%
(b) 20.3%
(d) 45.2%
(c) 2.58%
The total cost of painting per cm will be 45.2% i.e. option(d).
Total cost of painting = Rate × Surface area of sphere
We know the radius is increases by 10%.
Thus, the Surface area will change by 21%
using formula a + b + (a × b)/ 100
The total change in cost of painting will be
= 20+21 +(20x21)/100
= 45.2%.

Find the distance between each pair of points
Answer:
7.071068 ≈ 7.07
Step-by-step explanation:

On the incomplete table of values, we do not have any x values
So, we can make use of any x value
To do this, we make use of the following x values
x = -3, -1, 0, 1 and 3
Next, we substitute x = -3, -1, 0, 1 and 3 in the equation y = |x|
So, we have:
y = |-3| = 3
y = |-1| = 1
y = |0| = 0
y = |1| = 1

If the right triangle BAR were rotated 90° clockwise about Point B to what location would point A be relocated
Using rotation rules, considering the 90º clockwise rotation, the coordinates of point A are given as follows:
(-2,0).
What is the rule for a 90º clockwise rotation at a point other than the origin?The origin has coordinates (0,0), hence the rule for a 90º clockwise rotation about the origin is:
(x,y) -> (y, -x).
Considering a point (xP, yP) as reference, the rule for the coordinates of the vertices after the rotation is given as follows:
(x,y) -> (y - yP, -x + xP).
For this problem, point B is the reference point, hence the reference coordinates are as follows:

Area of the shaded part
In the picture, there is a square and a shaded region inside the square. The shaded portion has a 13.76 square meter area.
Given that,
In the picture, there is a square and a shaded region inside the square.
We have to find the shaded portion area.
The side of the square is 8cm.
Now,
First we see the unshaded region on the square is there are 4 unshaded regions.
In the figure u can see there is a unshaded region we named that has tile 1, tile2, tile 3, and tile 4.
If we restock them we can see that we got a circle with that 4 tiles.
Now, the side is 8 cm then the 1 tile will be of 4 cm.
So, the radius of the circle is 4 cm.
In the other picture we can see that the area of the shaded region is equal to area of square- area of circle.
Area of the shaded region =s²-πr²
Area of the shaded region =8²-π(4)²
Area of the shaded region =64-π(16)
Area of the shaded region =64-16π
Area of the shaded region =64-16(3.14)
Area of the shaded region =64-50.24
Area of the shaded region =13.76

One gram of protein contains 4 calories. One gram of fiber contains 2 calories. A protein bar has 80 calories from p grams of protein and f grams of fiber.
The equation 4p+2f=80 represents the relationship between these quantities.
Which pair of values could be the number of grams of protein and fiber in the protein bar?
Pairs of values that could be the number of grams of protein and fiber in the protein bar are:
10 grams of protein and 20 grams of fiber. That is, (10, 20)
and
15 grams of protein and 10 grams of fiber. That is, (15, 10)
Calculating value pairsFrom the question, we are to determine the pair of values that could be the number of grams of protein and fiber in the protein bar
From the given information,
The protein has 80 calories from p grams of protein and f grams of fiber
and
The equation that represents the relationship is
4p + 2f = 80
To determine the pair of values, we can determine the values of f for certain values of p
When p = 10
4p + 2f = 80
4(10) + 2f = 80
40 + 2f = 80
2f = 80 - 40
2f = 40
f = 40/2
f = 20
A pair of values is 10 grams of protein and 20 grams of fiber.
When p = 15
4p + 2f = 80
4(15) + 2f = 80
60 + 2f = 80
2f = 80 - 60
2f = 20
f = 20/2
f = 10
Thus,
Another pair of values is 15 grams of protein and 10 grams of fiber.
