Step-by-step explanation:
Equation A is true among the given equations.
What is a matrix?A matrix is an array of values arranged in rows and columns, such that they are used to represent a mathematical object.
Matrices are associative when they are multiplied. This means that any two adjacent matrices can be multiplied first and then the third one can be multiplied. This would yield the same answer. This means that equation A is true. In equation B, different matrices are multiplied and added. Therefore, the LHS is not equal to the RHS. In equation C, the order in which the matrices are written and multiplied is different. Matrices aren't commutative with multiplication. Therefore, the LHS is not equal to the RHS. Similarly, equation D is also wrong.Thus, we have found that among the given equations, equation A is true.

write an equation in slope-intercept for the line that has a slope of 1/2 and goes through the point (4, 7)
Answer:
y = 1/2x + 5
Step-by-step explanation:
The formula for an equation is y = mx + b
m is the slope. It is given
y = 1/2x + b
b is the y-intercept
In this case, we must substitute to find the y-intercept
We are given coordinate pair (4,7)
Plug our pair in and we get => 7 = 1/2(4) + b
=> 7 = 2 + b
easily, we find b = 5
We get our equation: y = 1/2x + 5

Julie says the most amount of time spent on homework is 1/2 times the least amount of time spent of homework. Is she correct? Explain
Answer:
Step-by-step explanation:
I believe this question is coming from a statistical data, which for whatever reasons is not present here. If Julie says the most amount of time spent, it meant that the time most time people spent on the homework. And if she says the least amount of time. This means that the least number of time people spent on the homework.
Then again, she says it is half times, this means that if 5 people spent the most amount of time in doing something, then 10 people must have spent the least amount of time doing the same exact thing.
I hope you understand

Ellen has a bag with 3 red marbles and 2 blue marbles in it. She is going to randomly draw a marble from the bag 300 times, putting the marble back in the bag after each draw. 3 red marbles and 2 blue marbles What is the best prediction for the number of times that Ellen will draw a blue marble?
Answer:
120
Step-by-step explanation:
Blue marbles = 2
Red marbles = 3
Total marbles = 2 + 3 = 5
If a marble is drawn 300 times ;prediction for the number of times a blue marble will be drawn :
P(drawing a blue marble) = number of blue marbles / total number of marbles
= 2 /5 = 0.4
Predicted number of times blue is drawn in 300 selections :
300 * 0.4 = 120
Approximately 120 times

What is the height of a cone with a slant height of 16 inches and a radius of 6 inches? Round your answer to the nearest whole number.
Answer:
14.8 inches
Step-by-step explanation:
Given that:
Slant height, l = 16 inches
Radius, r =. 6 inches
Using the relation :
h² + r² = l²
h² + 6² = 16²
h² = 16² - 6²
h² = 256 - 36
h² = 220
h = sqrt(220)
h = 14.832
h = 14.8 inches
how to do graphs of quadratic functions
Answer:
The Graph of a Quadratic Function
A quadratic function is a polynomial function of degree 2 which can be written in the general form.
Step-by-step explanation:
Example: Graph: f(x)=−x2−2x+3.
Solution:
Step 1: Determine the y-intercept. To do this, set x=0 and find f(0).
f(x)f(0)===−x2−2x+3−(0)2−2(0)+33
The y-intercept is (0,3).
Step 2: Determine the x-intercepts if any. To do this, set f(x)=0 and solve for x.
f(x)000x+3x======−x2−2x+3−x2−2x+3x2+2x−3(x+3)(x−1)0−3orx−1x==Set f(x)=0.Multiply both sides by −1.Factor.Set each factor equal to zero.01
Here where f(x)=0, we obtain two solutions. Hence, there are two x-intercepts, (−3,0) and (1,0).
Step 3: Determine the vertex. One way to do this is to first use x=−b2a to find the x-value of the vertex and then substitute this value in the function to find the corresponding y-value. In this example, a=−1 and b=−2.
x====−b2a−(−2)2(−1)2−2−1
Substitute −1 into the original function to find the corresponding y-value.
f(x)f(−1)====−x2−2x+3−(−1)2−2(−1)+3−1+2+34
The vertex is (−1,4).
Step 4: Determine extra points so that we have at least five points to plot. Ensure a good sampling on either side of the line of symmetry. In this example, one other point will suffice. Choose x=−2 and find the corresponding y-value.
x −2 y 3f(−2)=−(−2)2−2(−2)+3=−4+4+3=3Point(−2,3)
Our fifth point is (−2,3).
Step 5: Plot the points and sketch the graph. To recap, the points that we have found are
y−intercept:x−intercepts:Vertex:Extra point:(0,3)(−3,0) and (1,0)(−1,4)(−2,3)
Answer:
SOME ONE HELP!!! You are still at (1,5). The zombie is 8.7 units below you. Enter the correct coordinates of the zombie below.
Answer:
(1,-3.7)
Step-by-step explanation:
subtract the y axis to go down
5 - 8.7 = -3.7
The solution is B ( 1 , -3.7 )
The coordinates of the zombie is given by B ( 1 , -3.7 )
How does the transformation of a function happen?
The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units: y=f(x+c) (same output, but c units earlier)
Right shift by c units: y=f(x-c)(same output, but c units late)
Vertical shift:
Up by d units: y = f(x) + d
Down by d units: y = f(x) - d
Stretching:
Vertical stretch by a factor k: y = k × f(x)
Horizontal stretch by a factor k: y = f(x/k)
Given data ,
Let the initial point of the man be A
The value of A = A ( 1 , 5 )
Let the coordinates of the zombie be B
The value of B = B ( x , y )
The zombie is 8.7 units below
So , it is a vertical shift by 8.7 units
Therefore , the y coordinate will decrease by 8.7 units
Substituting the values in the equation , we get
B = A ( 1 , 5 - 8.7 )
B = B ( 1 , -3.7 )
Therefore , the value of B is B ( 1 , -3.7 )
Hence , the coordinates of B is B ( 1 , -3.7 )

The area of rectangular is 64m the length of the pool is 12 m less that the width .The situation can be represented by the equation x
Answer:
Width = 16 m
Length = 4 m
Step-by-step explanation:
The area of rectangular is 64m² the length of the pool is 12 m less that the width . The situation can be represented by the equation x
Area of a rectangle = Length × Width
L = W - 12
Hence:
64 = (W - 12) × W
64 = W² - 12W
W² - 12W - 64 = 0
Factor using
(W + 4)(W - 16) = 0
Width = 16m
Length = W - 12
Length = 16 m - 12 m
= 4 m

Answer:
ecall that 6 + 6 + 6 = 6 × 3
Instead of adding 6 three times, you can multiply 6 by 3 and get 18, the same answer.
Similarly,
6 + 6 + 6 + 6 + 6 + 6 + 6 = 6 × 7 = 42
Still by the same token,
2 + 2 + 2 + 2 = 2 × 4
The circumference of a circle is approximately 131.88 centimeters What is the area of the shaded region (6/10 of a circle)
Answer:
82.97cm^2
Step-by-step explanation:
Given data
Circumference= 131.88 centimeters
We want to find the area of 6/10 part of a circle
Firstly, let us find the area of the circle
We need to get the radius
C= 2πr
131.88= 2*3.142*r
131.88=6.284r
r= 131.88/6.284
r=20.98 cm
Area= πr^2
Area= 3.142*20.98^2
Area= 3.142*440.16
Area= 1382.98cm^2
Hence 6/10 of a 1382.98
=0.06*1382.98
=82.97cm^2
