I need help with number 4, thank you
Answer:
126Step-by-step explanation:
In number 4 the given figure is a parallelogram,
So,
Base of the parallelogram = 14
Height of the parallelogram = 9
Therefore,
Area of the parallelogram = Base × Height
= 14 × 9
= 126
Hence, area of figure in question no. 4 is 126 (Ans)

A prism is filled with 28 cubes with 1/2 unit lengths. What is the volume of the prism in cubic units?
Answer:
3.5 cubic units
Step-by-step explanation:
First, find the volume of one cube
Use the cube volume formula, V = s³, where s is the side length
V = (1/2)³
V = 1/8 cubic units
Now, find the volume of the prism by multiplying this by 28, since there are 28 cubes
28(1/8)
= 3.5
So, the volume of the prism is 3.5 cubic units

complete the table, vertex, and max or min. <3
Answer:
Step-by-step explanation:
The function describes a parabola
for find the value of y we have to substitute the value of x in the function
x = -1
y = (-1-2)^2 =9
(-1;9)
x = 0
y = (0-2)^2 = 4
(0;4)
x = 1
y = (1-2)^2= 1
(1;1)
x = 2
y = (2-2)^2 = 0
(2;0)
x= 3
y = (3-2)^2 = 1
(3;1)
for the second part we can solve the square of the binomial
y = x^2 -4x + 4
direction of opening : we have to see if the term that multiply x^2 is positive or negative. In this case is not expessed so it is 1, a positive number.
So the direction of opening is : upwards
line of symmetry: -b/2a where b is the term that multiply x and a the term that multiply x^2
x = 4/2 = 2
vertex: the x - coordinate of the vertex is the same of the line of symmetry
so x = 2
for find the y - coordinate we have to substitute the value of x in the equation
y = 4 - 8 + 4 = 0
vertex = (2;0)
the parabola has an upwards direction of opening so it has a point of minimum that is the vertex itself.
minimum of 0

QUESTION 1
Find the slope of a line through the points (7, –8) and (–5, –7).
a -12
b-15/2
c -2/15
d -1/12
Answer:
D
Step-by-step explanation:
Slope = y2-y1/x2-x1
(7,-8) = (x1,y1)
(-5,-7) = (x2,y2)
Slope = (-7+8)/(-5-7)
= 1/-12

2(x+2)-7=6x-4(1+x) solve for x
Answer:
x has no solution
Step-by-step explanation:
2x+4-7=6x-4-4x
2x-3=2x-4
-3=-4
Answer:
No solution
Step-by-step explanation:
2(x+2) -7 = 6x - 4(1+x) (Distribute 1st)
2x + 4 - 7 = 6x - 4 - 4x
2x - 3 = 2x - 4 (Combine like-terms)
2x - 2x = -4 + 3
0 = -1

Congratulations! You won a free grill in a sweepstakes! You know that you can fit a rectangular grill in your truck that has a width of 2 1/2 feet. The length of the grill can be up to three times the width. What is the largest possible perimeter your new grill can have to fit in your taco truck? Show your work.
Answer: 20 feet perimeter is the largest allowed
Step-by-step explanation: width=2.5 length=no more than 3x2.5
so find longest possible length allowed...
2.5x3=7.5
calculate largest perimeter allowed...
2(7.5+2.5)=20
solve the following quadratic by factoring: 6x^2-12x=0
Answer:
X=0,-2
Step-by-step explanation:
6 x ( x + 2 ) = 0 Divide each term in 6 x ( x + 2 ) = 0 by 6 . 6 x ( x + 2 ) 6 = 0 6 Cancel the common factor of 6 . x ( x + 2 ) = 0 6 Divide 0 by 6 . x ( x + 2 ) = 0 If any individual factor on the left side of the equation is equal to 0 , the entire expression will be equal to 0 . x = 0 x + 2 = 0 Set the first factor equal to 0 . x = 0 Set the next factor equal to 0 and solve. Tap for more steps... x = − 2 The final solution is all the values that make 6 x ( x + 2 ) 6 = 0 6 true. x = 0 , − 2
Maisy hiked for 5 hours and burned 750 calories. She wants to find out how many calories she burned per hour, so she wrote the equation 5x=750 , where x represents the number of calories Maisy burned per hour. How many calories did Maisy burn in one hour?
Answer:
x = 150
Step-by-step explanation:
Given that,
The equation that is used to find out how many calories she burned per hour, the equation is as follows :
5x = 750
We need to find how many calories did Maisy burn in one hour.
For 1 hour use unitary method such that,
x = (750/5)
x = 150
So, she can 150 calories in one hour.
A news channel on cable T.V. polled politicians on an issue to find out who agreed with a court decision. This is the graphic they used in their report.
Results by Party
A graph titled Results by Party has Political party on the x-axis, and Percent who agreed on the y-axis, from 53 to 63 in increments of 2. Democrats, 62; Republicans, 54; Independents, 54.
Source: mediamatters.org
What makes this graph misleading?
a.
The horizontal scale only shows three parties. It needs to show every party.
b.
The vertical scale is too broad. It needs to focus in on a narrower range.
c.
The horizontal scale exaggerates the differences between the parties.
d.
The vertical scale is too narrow. It needs to be a wider range, such as 0 to 100.
Please select the best answer from the choices provided
A
B
C
D
Answer: d. The vertical scale is too narrow. It needs to be a wider range, such as 0 to 100.
Step-by-step explanation:
The vertical scale is indeed too narrow. It needs to have a wider range that will enable a person who is looking at the graph, better compare the results shown because the magnitude of the number will be more apparent.
A range such as 0 to 100 would be ideal for this and would present the information in such a way that when a person looks at the graph, they understand the relative difference between the percentages who agreed with the court decision.

In the equation below a is a number between 0 and 1 8 x a = b which statement about the value of b is always true
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]0 \le a \le 1[/tex]
[tex]8*a =b[/tex]
Required
Determine the true statement about b
The question is incomplete as options are not given. However, a general explanation is as follows:
Rewrite [tex]8*a =b[/tex]
[tex]b = 8 * a[/tex]
When a = 0
[tex]b = 8 * 0 = 0[/tex]
When a = 1
[tex]b = 8 * 1 = 8[/tex]
This means that:
For [tex]0 \le a \le 1[/tex]
Then [tex]0 \le b \le 8[/tex]
This means that: b is a number between 0 and 8
