Write a formula for the given measure. Let P represent the perimeter in inches, and w represent the width in inches. Identify which variable depends on which in the formula.
Complete Question:
Write a formula for the given measure. Let P represent the perimeter in inches, and w
represent the width in inches. Identify which variable depends on which in the formula.
*The perimeter of a rectangle with a length of 5 inches
Answer:
P = 2(5 + w)
Or
P = 20 + 2w
P is the dependent variable
w is the independent variable
P depends on w.
Step-by-step explanation:
Given:
Perimeter of rectangle = P
Width of the rectangle = w
Length of the rectangle = l = 5 in.
Formula for perimeter of a rectangle = 2(length + width)
Plug in the values. Formula for the given measure would be:
P = 2(5 + w)
Or
P = 20 + 2w
P is the independent variable, while w is the dependent variable.
This is because the Perimeter (P) of the rectangle is dependent on the width (w). Whatever value of w we get would determine the value of P were would get. Therefore,
P depends on w.

Write sin(19°) in terms of cosine.
Answer:
cos(71)
Step-by-step explanation:
Since 19° is less than 90, we can express this in terms of confunction.
sin(θ) = cos(90-θ)
sin(19) = cos(90-19)
sin(19) = cos(71)

Convert (4, 3π/2) to rectangular form.
A) (0,4)
B) (0, -4)
C) (-4,0)
D) (4,0)
Answer:
(0, -4)
Step-by-step explanation:
The rectangular form is expressed as;
x = rcos theta
y = rsin theta
Given the coordinate (4, 3π/2)
r = 4
theta = 3π/2
Substitute
x = 4cos3π/2
x = 4cos270
x = 4(0)
x = 0
y= 4sin3π/2
y = 4sin270
y = 4(-1)
y = -4
Hence the required coordinate is (0, -4)

Answer:
900 ft cubed
Step-by-step explanation:
v=pi*r sqaured* h
The radius is 5 and sqaure 5 to get to 25. Multiply that by pi, which in your case is 3, and you get 25. Then mulitply that by 12, height, and you get your answer is 900.
Lmk if you need more help
Also, to do this on the calulator is easy as well. Just times pi(3 for you) by the raduis twice and then times that by the height. For example, for this question, I just typed in my calculator, 3 times 5 times 5 times 12 and I got 900.
Sorry if this doesn't make sense lol I'm not good at explaining things.

Which expression could be used to determine the perimeter of the triangle?
A 9x + 4
B 9(x + 4)
C 13x
D 13(x + 1)
Answer:
A. 9x + 4
Step-by-step explanation:
Perimeter of a triangle = side A + side B + side C
Side A = 2.5x + 3
Side B = x + 6
Side C = 5.5x - 5
Perimeter of a triangle = side A + side B + side C
= (2.5x + 3) + (x + 6) + (5.5x - 5)
= 2.5x + 3 + x + 6 + 5.5x - 5
= 2.5x + x + 5.5x + 3 + 6 - 5
= 9x + 4
Perimeter of a triangle = 9x + 4
The correct answer is A. 9x + 4

K. If you are told that two lines are perpendicular, what does this mean?
L. What are the similarities between parallel lines?
M. What is the relationship between two lines that are perpendicular?
Answer:
A) y=mx+b
B) The slope of a line is a number that describes both the direction and the steepness of the line. The slope of the line is either increasing, decreasing, horizontal or vertical.
C) m= rise/run =y2-y1/x2-x1
D) A rate of change describes how one quanity changes with respect to the other. The rate of Change for a line is the slope, the rise over run, or the change in y over the change in x.
E)The y-intercept of the line is the value of y where the line crosses the y-axis.
F)The x-intercept of the line is the value of x where the line crosses the x-axis.
G) The point-slope formula is y-y1=m(x-x1)
H)HOY stands for Horizontal line, slope =0, their equations are in the form y= a constant
I)VUX stands for Vertical line, slope =Undefined, their equations are in the form x= a constant
J)If two lines are parallel, this means that the slopes are the same and the y-intercept are different.
K) The slope of perpendicular lines are the negative reciprocals of each other, and a pair of these lines intersects at 90 degrees
L) The similarities between parallel lines are they have the same steepness, or same angle from the horizontal. Since they have the same steepness they have the same slope.
M)The relationship between two lines that are perpendicular intersect at right angles. they are coplanar lines

Step-by-step explanation:
11. Keng creates a painting on a rectangular canvas with a width that is four inches longer
than the height, as shown in the diagram below.
L= h +4 and H = h
A. Write a polynomial expression, in simplified form, that represents the area of the
canvas.
Keng adds a 3-inch-wide frame around all sides of his canvas.
B. Write a polynomial expression, in simplified form, that represents the total area of the canvas and the frame.
Part A
Answer: h^2 + 4h-------------------
Explanation:
We multiply the length and height to get the area
area = (length)*(height)
area = (h+4)*(h)
area = h(h+4)
area = h^2 + 4h .... apply the distributive property
The units for the area are in square inches.
===========================================================
Part B
Answer: h^2 + 16h + 60-------------------
Explanation:
If we add a 3 inch frame along the border, then we're adding two copies of 3 inches along the bottom side. The h+4 along the bottom updates to h+4+3+3 = h+10 along the bottom.
Similarly, along the vertical side we'd have the h go to h+3+3 = h+6
The old rectangle that was h by h+4 is now h+6 by h+10
Multiply these expressions to find the area
area = length*width
area = (h+6)(h+10)
area = x(h+10) ..... replace h+6 with x
area = xh + 10x .... distribute
area = h( x ) + 10( x )
area = h( h+6 ) + 10( h+6 ) .... plug in x = h+6
area = h^2+6h + 10h+60 .... distribute again twice more
area = h^2 + 16h + 60
You can also use the box method or the FOIL rule as alternative routes to find the area.
The units for the area are in square inches.
The area of the canvas without the frame is h² + 4h and with frame is h²+16h+60.
What is an area?Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.
Given that, Keng is painting on a rectangular canvas with a width that is four inches longer than the height,
w = h+4, height = h
Area = (length)x(height)
area = (h+4)x(h)
area = h(h+4)
area = h² + 4h
With the frame,
If we add a 3 inch frame along the border, then we're adding two copies of 3 inches along the bottom side. The h+4 along the bottom updates to h+4+3+3 = h+10 along the bottom.
Keng added a 3-inch-wide frame around the painting,
Therefore,
The h+4 will become h+4+3+3 = h+10
Similarly, along the vertical side = h+3+3 = h+6
Area = (h+10)(h+6) = h²+16h+60
Hence, the area of the canvas without the frame is h² + 4h and with frame is h²+16h+60.
