If you are trying to calculate a company's initial profit, you can graph the profit function
and find:
A)the highest point of the graph.
B)the point where the graph crosses the x-axis.
C)the lowest point of the graph.
D)the point where the graph crosses the y-axis.
(Make sure to explain)
Answer:
D) the point where the graph crosses the y-axis
Step-by-step explanation:
The "initial" value of a function is generally taken to mean the function value when the independent variable is zero.
On a graph of the profit function, that will be the y-intercept: the point where the graph crosses the y-axis.
__
The highest point on the graph will be the maximum profit.
The points where the graph crosses the x-axis will be where profit is zero, referred to as "break-even" points.
The lowest point on the graph will be where the profit is a minimum. That point may actually indicate a loss (negative profit).
Agnes pays state income tax equal to 3.75% of her federal taxable income. she pays federal income tax equal to 28.4% of her federal taxable income. this year, she paid $15,449.60 in federal income tax. how much did agnes pay in state income tax? a. $573.36 b. $4,387.69 c. $1,170.04 d. $2,040.00 please select the best answer from the choices provided a b c d
Based on the information the amount that Agnes paid as state income tax is $2,040.
What is the federal income?Federal Income Tax is the tax system in the United States, levied and governed by Internal Revenue Services (IRS) which helps determine the tax that is charged on the income earned by individuals, corporates, and various other legal entities.
The first step is to calculate Agnes' federal taxable income.
Federal taxable income=$15449.60/0.284
Federal taxable income= $54,400
The second step is to calculate Agnes' state income tax.
State income tax=0.0375 ×$54,400
State income tax=$2,040
Hence, the amount that Agnes paid as state income tax is $2,040.

A container in the shape of a rectangular prism has a height of 2 feet. Its length is four
times its width. The volume of the container is 200 cubic feet. Find the length and width of
the container.
Answer:
length = 20 feet and width = 5 feet
Step-by-step explanation:
Volume is equal to volume = height * width * length. The questions tells us the total volume is 200 cubic feet and that the lenght is equal to length = 4w. Set up the equation 4w * w * 2 = 200 cubic feet. Multiply to get 8w^2 = 200 and solve for w.

Answer:
x = 7y = 97°z = 19Step-by-step explanation:
The markings on the figure show this to be a parallelogram. That means opposite sides are congruent. Because the sides are parallel, "alternate interior" angles are also congruent.
__
Angle y forms a linear pair with the one marked 83°, so is supplementary to it:
y = 180°-83° = 97°
__
The angle marked y is an exterior angle to the triangle containing the angle marked (7x -5)°. As such, it is equal to the sum of the remote interior angles, the one marked (7x -5)° and the unmarked one that is congruent to (3x +32)°.
(7x -5) +(3x +32) = 97 . . . . . angle relations in the left-side triangle
10x +27 = 97 . . . . . . . collect terms
10x = 70 . . . . . . . . subtract 27
x = 7 . . . . . . . . divide by 10
__
The side marked Z is congruent to the opposite parallel side, so ...
z = 19
__
The missing measures are ...
x = 7y = 97°z = 19_____
Additional comment
You can also find the value of y by adding up the interior angles of the right-side triangle. The one not shown there is "alternate interior" to the one marked (7x -5)°, hence has the same measure. This gives ...
(7x -5) +(3x +32) +83 = 180
Subtracting 83° from both sides gives the equation we used above.

(2) State 3 angle measures that would create a right isoscele
triangle.
Answer:
1) 1, 1, [tex]\sqrt{2}[/tex]
2) 45°, 45°, 90°
Step-by-step explanation:
side lengths need to be proportional like 1, 1, [tex]\sqrt{2}[/tex], which is proportional for isoscele triangle.
isosceles is the one that has 90° angle and 2 equal angles so two 45° angles.
