Answer:
3081.24 cm³ (nearest hundredth)
Step-by-step explanation:
Formulas
[tex]\textsf{Circumference of a circle}=\sf 2 \pi r\quad\textsf{(where r is the radius)}[/tex]
[tex]\textsf{Volume of a cylinder}=\sf \pi r^2 h \quad\textsf{(where r is the radius and h is the height)}[/tex]
If a rectangular piece of paper is rolled along its length to form a cylinder:
circumference = 44 cmheight = 20 cmTo calculate the volume of the formed cylinder, determine the radius by using the circumference formula:
[tex]\implies \sf 2 \pi r = 44[/tex]
[tex]\implies \sf r = \dfrac{44}{2 \pi}[/tex]
[tex]\implies \sf r =\dfrac{22}{\pi}[/tex]
Substitute the round radius into the formula for Volume and solve for V:
[tex]\implies \sf V=\pi \left(\dfrac{22}{\pi}\right)^2(20)[/tex]
[tex]\implies \sf V=\pi \left(\dfrac{484}{\pi^2}\right)(20)[/tex]
[tex]\implies \sf V=\left(\dfrac{484}{\pi}\right)(20)[/tex]
[tex]\implies \sf V=\dfrac{9680}{\pi}[/tex]
[tex]\implies \sf V=3081.239698...cm^3[/tex]
Therefore, the volume of the cylinder is 3081.24 cm³ (nearest hundredth).

if the following data were linearized using logarithms, what would be the equation of the regression line? Round the slope and y-intercept of the regression line to three decimal places. x2,3,4,5,6 y73,77,85,101,133
A. log(y) =-1.706x + 0.064
B. log(y) =-0.064x + 1.706
C. log(y) = 1.706x + 0.064
D. log(y) = 0.064x + 1.706
The regression equation is (d) log(y) = 0.064x + 1.706
How to determine the regression equation?The table of values is given as:
x 2 3 4 5 6

Calculate the logarithm of the y values.
So, we have:

log(y) 1.86 1.89 1.93 2 2.12
Next, we enter the above values in a regression calculator.
From the calculator, we have the following summary:
Sum of X = 20Sum of Y = 9.8Mean X = 4Mean Y = 1.96Sum of squares (SSX) = 10Sum of products (SP) = 0.63The regression equation is then represented as:
log(y) = bx + a
Where:

A rectangular lot is 80 yards long and 50 yards wide.
Give the length and width of another rectangular lot that has the same perimeter but a larger area.
Answer:
55 Wide and 75 Long works.
Step-by-step explanation:
Since the Perimeter of the original is likely 80 + 80 +50 + 50 = 260 since it it a rectangular lot, 55 + 75 + 55 + 75 = 260 as well, meaning no change in perimeter. Now when we look at the area 80 x 50 = 4000, but
55 x 75 = 4125, leading to a larger plot

1.20City planners are planning to build a new community park. They agree that the park will be rectangular in shape, but the proposed
dimensions changed. At the most recent meeting, it was determined that the length would remain at 21.6 meters but that the width
would increase by 4.7 meters. So, the park would now cover an area of 714.96 square meters.
Which equation can be used to determine the original width of the park?
Answer:
(c) 714.96 = 21.6(w +4.7)
Step-by-step explanation:
The area of the rectangular park will be the product of its length and width. This relation is used to write an equation to find the original width of the park.
WidthLet w represent the original width of the park in meters. The new width is 4.7 meters more, so is represented by (w +4.7).
Other dimensionsThe length of the park is given as 21.6 meters. The area is given as 714.96 square meters.
Area formulaThe various dimensions of the park are related by the area formula:
A = LW
714.96 = 21.6(w +4.7)

A delivery truck is transporting boxes of two sizes: large and small. The large boxes weigh 60 pounds each, and the small boxes weigh 25 pounds each. There are 105
boxes in all. If the truck is carrying a total of 4550 pounds in boxes, how many of each type of box is it carrying?
Answer: The truck is carrying 55 large boxes and 60 small boxes
Step-by-step explanation:
Let x represent the number of large boxes
Therefore,
The number of small boxes = 115 - x
[tex]\therefore[/tex] According to the question
60x + 25(105 -x) = 4550
60x + 2625 - 25x = 4550
35x = 4550 - 2625
35x = 1925
x = 55
Number of large boxes = x = 55
Number of small boxes = 115 - 55 = 60

2. In 2007, the cost of mailing a first-class letter was 41 cents. Has the inflation rate stayed constant since 1991?
Based on the function given, the year when the cost of mailing a first class letter would reach 60 cents is 2007.
If the cost of mailing a first-class letter is 41 cents, then the inflation rate has not stayed constant.
What year does the cost reach 60 cents?0.60 = 0.29 (1.046)^t
0.60 / 0.29 = (1.046)^t
log (2.07) = t x log (1.046)
t = 16 years
Added to 1991:
= 1991 + 16
= 2007

If cos a = 0.871 and cos ß= 0.338 with both angles' terminal rays in Quadrant-I, find the values of
tan(a + 3) =
Your answers should be accurate to 4 decimal places.
Answer:
tan(α+β) ≈ -5.8688
Step-by-step explanation:
You can use the formula for the tangent of the sum of angles, or you can use a calculator to find the angles. The latter is much simpler.
Calculator solutiontan(α+β) = tan(arccos(0.871) +arccos(0.338))
tan(α+β) ≈ -5.8688
Note that the two angles total slightly more than 90°, so the tangent of their sum is a large negative number.
Trig identity solutionThe use of trig identities also requires a calculator, and many more steps.
The tangent of the angle can be found from the cosine using ...
tan(x) = √((1/cos(x))² -1)
tan(α) = √((1/0.871)² -1) ≈ √(1.1481056² -1) ≈ 0.56404479
tan(β) = √((1/0.338)² -1) = √(2.9585799² -1) ≈ 2.7844559
And the tangent of the sum of angles is ...
tan(α +β) = (tan(α) +tan(β))/(1 -tan(α)tan(β))
tan(α+β) = ((0.56404479 +2.7844559)/(1 -(0.56404479)(2.7844559))
tan(α+β) = 3.3485007/(1 -1.5705579)
tan(α+β) ≈ -5.8688

Additional comment
The approximate angles are ...
α ≈ 29.4249°
β ≈ 70.2448°
Then α+β ≈ 99.6699°
