You can use the midpoint formula: [tex]\frac{ChangeInX}{2} ,\frac{ChangeInY}{2}[/tex]
So, the Change In X is: -1 - 4 = -5
And the Change in Y is: 6 - 1 = 5
Once you divide both of the changes by 2, you get
X: [tex]-\frac{5}{2}[/tex]
Y: [tex]\frac{5}{2}[/tex]
So the midpoint is: ( [tex]-\frac{5}{2}[/tex], [tex]\frac{5}{2}[/tex])

No. 3
You can use the midpoint formula: [tex]\frac{ChangeInX}{2} ,\frac{ChangeInY}{2}[/tex]
So, the Change In X is: -3 - (-9) = 6
And the Change in Y is: 4 - 3 = 1
Once you divide both of the changes by 2, you get
X: 2
Y: [tex]\frac{1}{2}[/tex]
So the midpoint is: ( 2, [tex]\frac{1}{2}[/tex])
__________________________________________________________
No. 4
You can use the midpoint formula: [tex]\frac{ChangeInX}{2} ,\frac{ChangeInY}{2}[/tex]
So, the Change in X is: -1 - X
And the Change in Y is: -12 - Y
Once you divide both of the changes by 2, you get
X: [tex]\frac{-1-X}{2} = -9[/tex]
-1 - X = -18
-X = -17
X = 17
Y: [tex]\frac{-12-Y}{2} = -7[/tex]
-12 - Y = -14
-Y = -2
Y = 2
So the endpoint is: (17, 2)
__________________________________________________________
No. 5
You can use the midpoint formula: [tex]\frac{ChangeInX}{2} ,\frac{ChangeInY}{2}[/tex]
So, the Change in X is: -14 - X
And the Change in Y is: -13 - Y
Once you divide both of the changes by 2, you get
X: [tex]\frac{-14-X}{2}=-11[/tex]
-14 - X = -22
-X = -8
X = 8
Y: [tex]\frac{-13-Y}{2} =-10[/tex]
-13 - Y = -20
-Y = -7
Y = 7
So the endpoint is: (8, 7)

The graph represents a function with the form f(x) = asin(bx + c).
On a coordinate plane, a function has a maximum of 6 and minimum of negative 6. It completes one period at StartFraction 2 pi Over 3 EndFraction. It decreases through the y-axis at (0, 2).
Which values of a, b, and c are possible?
a = 6, b = 1, c = StartFraction pi Over 3 EndFraction
a = 6, b = 3, c = pi
a = 3, b = 1, c = StartFraction pi Over 3 EndFraction
a = 3, b = 6, c = pi
Answer:
a=6, b=3, c=pi
Step-by-step explanation:
Got it right on edge
Using sine function concepts, it is found that possible values for a, b and c are given by:
[tex]a = 6, b = 3, c = \pi[/tex]The standard sine function is given by:
[tex]y = a\sin{(bx + c)}[/tex]
In which:
The amplitude is 2a. The period is [tex]\frac{2\pi}{b}[/tex]. The horizontal shift is c.In this problem:
Maximum of 6 and minimum of negative 6, hence the amplitude is 12, that is, [tex]2a = 12 \rightarrow a = 6[/tex].The period is of [tex]\frac{2\pi}{3}[/tex], hence [tex]\frac{2\pi}{3} = \frac{2\pi}{b} \rightarrow b = 3[/tex].It passes through the y-axis at (0,2), which is one third of the maximum. Considering the shift, we have that [tex]c = \pi[/tex].You can learn more about the sine function at https://brainly.com/question/16818112

PLEASE HELP I KNOW ITS JIM IS CORRECT BUT I NEED AN EXUSE FOR THE WRONG ANSWER “I CHOSE LOU BECAUSE” PLEASE HURRY MY TEACHER ALREADY SUBMITTED IT AND I HAVE 0 OUT OF 8
Answer:
Step-by-step explanation:
8 hundredth is ten larger that 8 thousands so Jim is correct and Lou is not right for the following reason:
8 hundredth means that the number is on the right side after the decimal
if we put it as a fraction:
8/100 and 8/1000
comparing:
take a common denominator(1000 for the two fractions)
8/100=80/1000
80/1000>8/1000
the nominator 80 is greater than 8
( this is one way to compare and prove)
Lou is wrong because on the number line 0.008 comes before 0.08
for example a number 2.08( 2 and 8 hundredth)
and 2.008 ( 2 and 8 thousandth)
ones decimal tenth hundredth thousandth
2 . 0 8
2 . 0 0 8
the more the number goes to the right of the decimal the smaller the fraction

What is the solution to the inequality 4(2m + 3)-7<3?
A m>-1
6. m<1
C. m>8
D. m < 8
Answer:
m < -(1/4)
Step-by-step explanation:
4(2m + 3)-7 < 3
First, multiply inside the parenthesis with 4.8m + 12 - 7 < 3
Add/subtract like terms on the right side of the inequation.8m + 5 < 3
Subtract 5 from both sides of the inequation.8m < -2
Divide both sides with 8.m < -(1/4)
The correct solution is m < -1/4, which is not among the provided options.
To find the solution to the inequality 4(2m + 3) - 7 < 3, let's solve it step by step.
First, we simplify the left side of the inequality:
4(2m + 3) - 7 < 3
8m + 12 - 7 < 3
8m + 5 < 3
Next, we isolate the variable term by subtracting 5 from both sides:
8m + 5 - 5 < 3 - 5
8m < -2
To solve for m, we divide both sides of the inequality by 8:
(8m)/8 < (-2)/8
m < -1/4
So, the correct solution to the inequality is m < -1/4.
Comparing the options provided:
A. m > -1: This option is not correct because the solution to the inequality is m < -1/4, not m > -1.
B. m < 1: This option is not correct because the solution is m < -1/4, not m < 1.
C. m > 8: This option is not correct because the solution is m < -1/4, not m > 8.
D. m < 8: This option is not correct because the correct solution is m < -1/4, not m < 8.

The geometric average of -17%, 30%, and 35% is Multiple Choice a. 12.00% b. 16.00% c. 13.36% d. 27.10%
The geometric average of -17%, 30%, and 35% is option c) 13.36%.
To find the geometric average, we multiply the values together and then take the nth root, where n is the number of values.
For the given percentages -17%, 30%, and 35%, we calculate the geometric average as follows:
Geometric Average = (1 + (-0.17))(1 + 0.30)(1 + 0.35)^(1/3) - 1
Simplifying the expression:
Geometric Average = (0.83)(1.30)(1.35)^(1/3) - 1
Calculating further:
Geometric Average ≈ 1.1336 - 1 ≈ 0.1336
Converting to percentage:
Geometric Average ≈ 0.1336 * 100 ≈ 13.36%
Therefore, the geometric average of -17%, 30%, and 35% is approximately 13.36%, corresponding to option c).
The geometric average is useful for calculating the average rate of change over multiple periods. It takes into account the compounding effect of successive percentage changes. It is important to note that the geometric average is different from the arithmetic average, which is calculated by summing the values and dividing by the number of values.

what is the mass of crate with a net force of 300N and accelerate it by 0.750 m/ s²?
WITH SOLUTION
Answer:
m = 400 kg
Step-by-step explanation:
[tex]\because F = ma\\ \\
\therefore m =\frac{F}{a} \\ \\
\therefore m = \frac{300}{0.75} \\ \\
\therefore m = \frac{30000}{75} \\ \\
\therefore m = 400\: kg[/tex]
We have that the mass of crate with a net force of 300N and accelerate it by 0.750 m/ s² is
m=400kg
From the question we are told
The mass of crate with a net force of 300N and accelerate it by 0.750 m/ s²

QUESTION 8 We will define a checkerboard matrix to be a square matrix A = (aj), where if i + j is even dij = if i + j is odd 8.1 Write out the 4x4 checkerboard matrix. 8.2 Find the basis for the nullspace of A, and the nullity and rank of A. 8.3 What will be the rank and nullity of the 17x17 checkerboard matrix?
The 4x4 checkerboard matrix is constructed with alternating 1s and 0s based on the position of the elements. The basis for the nullspace of the checkerboard matrix is found, and its nullity and rank are determined. Additionally, the rank and nullity of a 17x17 checkerboard matrix are determined.
8.1 To construct the 4x4 checkerboard matrix, we assign values based on the parity of the row and column indices. If the sum of the row index (i) and column index (j) is even, the element (aij) is 1. Otherwise, if the sum is odd, the element is 0. The resulting 4x4 checkerboard matrix is:
A = |1 0 1 0|
|0 1 0 1|
|1 0 1 0|
|0 1 0 1|
8.2 to find the basis for the nullspace of A, we need to solve the equation Ax = 0, where x is a vector. By performing row operations on the matrix, we can bring it into row-echelon form:
|1 0 1 0|
|0 1 0 1|
|1 0 1 0|
|0 1 0 1|
Row 3 - Row 1:
|1 0 1 0|
|0 1 0 1|
|0 0 0 0|
|0 1 0 1|
Row 4 - Row 2:
|1 0 1 0|
|0 1 0 1|
|0 0 0 0|
|0 0 0 0|
The reduced row-echelon form shows that the last two rows are dependent on the first two rows. Therefore, the basis for the nullspace is the vector {(-1, 1, -1, 1)}. The nullity of A, which is the dimension of the nullspace, is 1.
The rank of A is the number of linearly independent rows, which in this case is 2.
8.3 The rank and nullity of the 17x17 checkerboard matrix can be determined using the same approach. Since the matrix is larger, it is not feasible to write it out here. However, we can observe a pattern based on the size of the matrix. For an n x n checkerboard matrix, if n is even, the rank will be n/2 and the nullity will also be n/2. If n is odd, the rank will be (n + 1)/2 and the nullity will be (n - 1)/2.
Therefore, for the 17x17 checkerboard matrix, the rank will be (17 + 1)/2 = 9, and the nullity will be (17 - 1)/2 = 8.
In summary, the basis for the nullspace of the 4x4 checkerboard matrix is {-1, 1, -1, 1}, resulting in a nullity of 1 and a rank of 2. For the 17x17 checkerboard matrix, the rank is 9, and the nullity is 8.
