A park is rectangular with a length of 1/2 miles. If the area of the park is 6/8 square miles, what is its width? Input your answer as a fraction.
giving 40 points! please help soon <33
Step-by-step explanation:
Area of Park = Length * Width
Therefore Width = Area / Length
= (6/8) / (1/2) = (6/8) * (2/1) = 3/2 miles.
Answer:Area of Park = Length * Width
Therefore Width = Area / Length
= (6/8) / (1/2) = (6/8) * (2/1) = 3/2 miles.

Answer:
Step-by-step explanation - w= o
Combine like terms in each expression
1. 1/4k+1/4m-2/3k+5/9m
2. -4b + 2w + (-4b) + 8w
3. 6- 5z + 8 - 4z + 1
Answer:
5/12k = 29/36m
8b = 10w
9z = 15
Step-by-step explanation:
Combining the like terms in these sets of equations is quite easy and straightforward. All we do is carry the like terms to either of the side of the equation, and question is solved. As in below
1/4k + 1/4m - 2/3k + 5/9m =
1/4k - 2/3k + 1/4m + 5/9m = 0
-5/12k + 29/36m = 0
5/12k = 29/36m
-4b + 2w + (-4b) + 8w =
-4b - 4b + 2w + 8w = 0
-8b + 10w = 0
8b = 10w
6- 5z + 8 - 4z + 1 =
6 + 8 + 1 - 5z - 4z = 0
15 - 9z = 0
9z = 15

what is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Let w = the number of weeks.
Let d = the number of dollars April pays the service.

A line passes through the points (4,8) and (2,0). What is its equation in slope-intercept
form?
Answer:
The answer is y = 4x - 8.
Step-by-step explanation:
☆Remember: [tex]m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
☆Slope-intercept: [tex]y = mx + b[/tex]

☆We need to find the slope first. So just plug in according to the slope formula!
[tex]m = \frac{0 - 8}{2 - 4} = \frac{ - 8}{ - 2} = 4[/tex]

☆Now we need to find the y-intercept. We are going to plug in the slope and a set of coordinates to find the y-intercept.

What are all values of x for which the function f defined by f(x)=x3+3x2−9x+7 is increasing ?
(A) −3
(B) −1
(C) x<−3 or x>1
(D) x<−1 or x>3
(E) All real numbers.
Answer:
C. [tex]x < -3[/tex] or [tex]x > 1[/tex].
Step-by-step explanation:
Let [tex]f(x) = x^{3}+3\cdot x^{2}-9\cdot x +7[/tex], the first derivate of the function is:
[tex]f'(x) = 3\cdot x^{2}+6\cdot x -9[/tex] (1)
By the Quadratic Formula, we determine the roots of this polynomial:
[tex]x_{1} = 1[/tex], [tex]x_{2} = -3[/tex]
And the factorized form of the polynomial is:
[tex](x-1)\cdot (x+3) > 0[/tex]
By law of Signs, the polynomial is increasing when [tex]x-1 > 0[/tex] and [tex]x +3 > 0[/tex] or [tex]x-1 < 0[/tex] and [tex]x+3 < 0[/tex], which means that:
[tex]x < -3[/tex] or [tex]x > 1[/tex]
Therefore, the right answer is C.
Answer:
The correct option is an option (c).
Given:
The given function is,
[tex]f(x)=x^{3}+3x^{2}-9x+7[/tex]
Computation:
The function is increasing when [tex]f'(x)>0[/tex].
Now, differentiating the given function with respect to [tex]x[/tex] up to first order we get,
[tex]f'(x)=3x^{2}+3(2x)-9(1)+0\\f'(x)=3x^{2}+6x-9\\=3(x^{2}+2x-3)\\=3(x(x+3)-1(x+3))\\=3(x+3)(x-1)[/tex]
So, the sign function is,
Therefore, [tex]f'(x)>0[/tex] when [tex]x\in (-\infty ,-3)\cup (1,\infty )[/tex]
So, [tex]f(x)[/tex] is increasing on [tex]x<-3[/tex] or [tex]x>1[/tex]
Hence, the correct option is an option (c).

What is the equation, in point-slope form, of the line
that is parallel to the given line and passes through the
point (4, 1)?
Answer:
Step-by-step explanation:
Given:
The line parallel to the given line containing the points (-3,3) and (-2,1).
Also, the parallel line passes through the point (4,1).
We need to determine the equation of the line in slope - intercept form.
Slope:
Since, the two lines are parallel, then their slopes are equal.
Thus, the slope of the parallel line can be determined using the formula,
Substituting the points (-3,3) and (-2,1), we get;
Thus, the slope of the line is
Equation of the line:
The equation of the line can be determined using the formula,
Since, the line passes through the point (4,1), let us substitute the point (4,1) in the above formula, we have;
Thus, the equation of the line is

Answer:
First option at second row , Option( C )
Step-by-step explanation:
In order to solve the problem,
First we need to arrange the numbers in ascending order.
4 , 7 , 8 , 10 , 11 , 13 , 15 , 15 , 22 , 28
Median = [tex]\frac{11 + 13}{2}[/tex]
= 12
From the first range ( 4,7,8,10,11 ) , we can find Q1 also known as first quartile where Q1 = 8 ( middle-most number).
Similarly, from the second range ( 13,15,15,22,28 ) , we can find Q2 also known as third quartile where Q3 = 15 (middle-most number ).
Now, for the box plot,
We need to draw a number line from 0 to 32.
Next, we need to draw a box from Q1 to Q3 with a vertical line through the median.
Next, we put dots above 4 and 28 since our numbers start from 4 and end with 28.
Finally we join the dots and the box plot with a straight line.
Hence, option C is the correct choice.
