Step-by-step explanation:
You are combining like terms.
1.) find all of the #x³ and there is only one and that is -x³ so that limits the problem to B or D.
2.) now you find all of the #x² and there are three of them being 10x², -x², and 4x². Now that you have identified them you will add them together to get a sum of 13x²
you don't have to do anymore of the question because D does not have 13x² so it is B.

Which number line represents the solution set for the inequality which number line represents the solution set for the inequality 2x-6 is less than or equal to 6(x-2)+8
Answer:
The answer is C
The correct answer is option (C).
What is inequality?Inequality shows relation between two expression which are not equal to each others.
The given inequality is,
2x-6 ≥ 6(x-2)+8
Simplify this inequality,
2x-6 ≥ 6x-12 +8
2x-6 ≥ 6x-4
⇒4x≤-2
⇒x≤-0.5
Inequality shows that values less than or equal to -0.5 are the solutions.
Therefore, option C is correct.

A university dean is interested in determining the proportion of students who receive some sort of financial aid. Rather than examine the records for all students, the dean randomly selects 200 students and finds that 118 of them are receiving financial aid. The 95% confidence interval for is 0.590.07. Interpret this interval. A. It can be said that 95% of the students get between 52% and 66% of their tuition paid for by financial aid. B. One can be 95% confident that between 52% and 66% of the sampled students receive some sort of financial aid. C. One can be 95% confident that the true proportion of all students receiving financial aid is between 0.52 and 0.66. D. One can be 95% confident that 59% of the students are on some sort of financial aid.
Answer:
C. One can be 95% confident that the true proportion of all students receiving financial aid is between 0.52 and 0.66
Step-by-step explanation:
Given that the confidence interval is a term that defines a range of values with the probability to contain a population value that has an actual degree of confidence.
This is represented in a situation where population means falls in between upper and lower intervals.
Hence, in this case, the correct interpretation is option C: One can be 95% confident that the true proportion of all students receiving financial aid is between 0.52 and 0.66
Solve A=w – 5 for w.
Answer: w=A + 5
Step-by-step explanation:
Thats my answere
Answer:
w=A+5
Step-by-step explanation:
We are starting with A=w-5 but to make things a little easier, we will flip the equation so it will look like w-5=A, now let's solve it
Add 5 to both sides,
w-5+5=A+5 once we simplify this we get our final answer,
w=A+5

Find the circumference of a circle with a Radius = 4 ft. Use 3.14 for it, and round to 2 decimal places.
Answer:
Circumference would be 25.12ft
Step-by-step explanation:
So circumference formula is pi(diameter)
We know the radius so to find the diameter we multiply the radius by 2.
so 4(2)=8
and since pi is 3.14 then multiply 8(3.14)
youll get 25.12
Answer:25.12
Step-by-step explanation:
formula is d(pi)
so 8(3.14)
25.12

The length of a rectangle is twice its width. The length is 412 feet. What is the area of the rectangle?
Answer:
Length is twice the Width
Perimeter = 126 ft.
let width = W
length = 2W
P = 2 length + 2 width
126 ft. = 2(2W) + 2W
126 ft. = 6W
21 ft. = W
width is 21ft., length is 42 ft.
Step-by-step explanation:
HOPE IT HELPS.
Answer:
Length= 412 feet
Breadth = 412/2 (as length is twice the breadth)
= 206 feet
therefore, area = l*b
= 412 * 206
= 84872 feet^2

Leon throws a ball off a cliff. The graph represents a relation that models the ball’s height, h, in feet over time, t, in seconds.
What is the domain?
{t| 0 ≤ t ≤ 3}
{t| 0 ≤ t ≤ 48}
{t| 0 ≤ t ≤ 64}
{t| all real numbers}
Answer:
{t|<t<3}
Step-by-step explanation:
The domain of the relation represented by the graph is the time from 0 to 3 seconds the range of the relation is the heights from 0 to 64 feet.
The domain of the graph is, {t | 0 ≤ t ≤ 3}
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
Leon throws a ball off a cliff.
And, The graph represents a relation that models the ball’s height, h, in feet over time, t, in seconds.
Hence, We get;
The domain is the set of input values of the function.
And, From the graph, the input values are represented on the t-axis.
So, The values on the t-axis start from t = 0 and ends at = 3
This means that the domain of the graph is 0 ≤ t ≤ 3
Hence, the domain of the graph is {t| 0 ≤ t ≤ 3}

HELP!!!!!!
Answer:
a would equal -6
Step-by-step explanation:
First, use y=mx+b to find the y-intercept (plug in (x,y) and 1/2 for m)
-2=4(1/2)+b this would simplify to -2=2+b
Subtract 2 from both sides
-2-2=2-2+b
b=-4 our y-intercept is -4
our new equation would be y=1/2x-4, graph this equation and find a point that correlates with the -4 on the y-axis and is in the line, that point will be -6
To prove our point we can write the equation using our new points (-4,-6) and we will get -4 as our "b" or y-intercept
-6=-4(1/2)+b
-6=-2+b add -2 to both sides
-4=b
Which interval contains a local minim um for the
graphed function?
[-4,-2.5]
[-2,-1]
[1, 2]
[2.5, 4]
Answer:
Option (4)
Step-by-step explanation:
From the graph attached,
Local minimum → (3, -4)
Global Maximum → (-0.44, -4.3)
Maximum of the function → (1.7, 0.7)
Since, local maximum lies in the interval 2.5 ≤ x ≤ 4
Interval that contains the local minimum will be→ [2.5, 4]
Therefore, Option (4) will be the correct option.

Alan is building a garden shaped like a rectangle with a semicircle attached to one short side. If he has 90 feet of fencing to go around it, what dimensions will give him the maximum area in the garden.
Answer:
long side, semicircle diameter: 180/(4+π) ft ≈ 25.2 ftshort side: 90/(4+π) ft ≈ 12.6 ftStep-by-step explanation:
Let the rectangle dimensions be x and y. Assume that x represents the "short" side, so it is also the diameter of the semicircle. Then the perimeter is ...
P = x + 2y + πx/2 = 90
The area is the area of the rectangle added to the area of the semicircle:
A = xy + (1/2)π(x/2)^2 = x(π/8x +y)
Solving the perimeter equation for y, we get
y = (90 -x -π/2x)/2
and the area equation becomes ,..
A = x(π/8x +45 -x/2 -π/4x)
A = x(45 -x(1/2 +π/8))
The graph of A(x) is a parabola opening downward with zeros at x=0 and x=45/(1/2+π/8) = 360/(4+π).
The vertex (maximum) of the area curve will be halfway between the zeros, at ...
x = (0 +360/(4+π))/2 = 180/(4+π)
The value of y is then ...
y = (90 -x(1 +π/2))/2 = (1/2)(90 -(180/(4+π))(2+π)/2) = (1/2)(90)(1 -(2+π)/(4+π))
y = 45(4+π-2-π)/(4+π) = 90/(4+π)
The rectangle dimensions are 90/4+π) by 180/(4+π), with the semicircle diameter equal to 180/(4+π).
__
That's about 25.2 ft by 12.6 ft with the semicircle attached to the long side.
