Calculate the muscular work completed by four men. Four men carry 20 boxes each up a ramp as shown. Each box weighs 5 pounds. Remember that muscular work is calculated by multiplying the weight by the vertical distance. In the calculation, disregard the weight of the men and consider only the muscular work done carrying the boxes.
A. 600 ft-lbs
B. 1200 ft-lbs
C. 2400 ft-lbs
D. 3600 ft-lbs
Answer:
2400 foot pounds
Step-by-step explanation:
The amount of work done by the four men is 1200 ft-lbs. so option B is correct.
How to calculate work done?The muscular work done by each man is equal to the weight of the boxes carried multiplied by the vertical distance moved.
The weight of each box is 5 pounds, and each man carries 20 boxes, so the total weight carried by each man is:
20 boxes x 5 pounds/box = 100 pounds
The vertical distance moved is the height of the ramp, which is 30 feet.
Therefore, the muscular work done by each man is:
Muscular work = weight x vertical distance
Muscular work = 100 pounds * 30 feet
Muscular work = 3000 ft-lbs
Since there are four men carrying boxes, the total muscular work done is:
Total muscular work = 4 * 3000 ft-lbs = 12000 ft-lbs
Therefore, the answer is B. 1200 ft-lbs.

Al, Barb, and Calvin shared a large pepperoni pizza after school. Al ate 1/3 of the pizza, Barb ate 1/4 of the pizza. and Calvin ate the rest. What is the ratio of Al's share of the pizza, to Barb's share, to Calvin's share?
a. 4:3:5
b. 3:4:7
c. 5:4:3
d. 3:4:5
e. 4:5:7
Answer:
A: 4:3:5
Step-by-step explanation:
Al ate 1/3 of the pizza. 1/3 can also be written as 4/12. Barb ate 1/4 of the pizza. 1/4 can also be written as 3/12. 4/12 plus 3/12 is equal to 7/12. One whole would be 12/12, so to get the remaining amount of pizza, do 12/12-7/12, to give you 5/12. 4:3:5. We needed to make all of the fractions have a common denominator in order to solve this particular problem.

The diameter of a circle has endpoints (2,-6) and (-4,-16).
Enter an equation for the circle in standard form.
Answer:
[tex](x + 1)^{2} + (y + 11)^{2} = 34[/tex]
Step-by-step explanation:
First find the midpoint of the segment from (2, -6) to (-4, -16)
((2 - 4)/2, (-6 - 16)/2)
(-2/2, -22/2)
(-1, -11) is the midpoint and is the center of the circle
Now find the distance between the 2 given points and divide by 2 to get the radius of the circle
d = [tex]\sqrt{(2 + 4)^{2} + (-6 + 16)^{2} }[/tex]
= [tex]\sqrt{6^{2} + 10^{2} }[/tex]
= [tex]\sqrt{36 + 100}[/tex]
= [tex]\sqrt{136}[/tex]
r = [tex]\sqrt{136}[/tex]/2
[tex]r^{2}[/tex] = 136/4 = 34
Equation of circle with center at (-1, -11) and radius = [tex]\sqrt{34}[/tex] is
[tex](x + 1)^{2} + (y + 11)^{2} = 34[/tex]

What is an exponential function?
An exponential function can be defined as a mathematical function whose values are generated by a constant that is raised to the power of the argument. Mathematically, an exponential function is represented by this formula
f(x) = eˣ
11 - 9 = 2 = 2¹
15 - 11 = 4 = 2²
23 - 15 = 8 = 2³
39 - 23 = 16 = 2⁴
Therefore, we can deduce that the parent function for this function represented in the table is an exponential function.
If function f was translated up to 5 units, then f(x) values would be increased by 5. Also, a point in the table for the transformed function is equal to (1, 4).

Answer:
4
Step-by-step explanation:
cos(-π) = -1 [in radians]
3-(-1) = 4
There are many ways to answer this but, I'll try to explain it.
You can see that you are computing a limit when some n approaches negative PI. You get to substitute negative PI instead of n and compute cos(-pi) which is -1.
Then compute f(x) - (-1) = 3 - (-1) = 4 which is a result.
The way you can imagine cos(-pi) or cos(-90deg) is by dragging point in a unit circle beneath x-axis and to the bottom y-axis (-90 angle), the y coordinate tells you the cosine value at (-90) and because you have dragged the point on the unit down to y-axis the value is -1.
Hope this helps.
