Step 1: learn to draw a free-body diagram. Read your school notes or look up a web site on the subject.
Step 2: Denote the angle of the ramp with the horizontal as theta=tan^(-1)(20/30)=33.69 degrees (approx.)
Step 3: denote the mass of the object as m=100 lb-mass.
Step 4: find force due to mass and gravity = -100g = -100 lb-force. (downwards), denoted by the vector F=(0,-100) lb-force.
Step 5: resolve force along incline:
Force parallel to incline = F1 = -100(cos(theta))
=-83.21 lb-force (negative => down the incline)
Step 6: resolve force perpendicular to incline
= F2 = -100(sin(theta)
=-55.47 lb-f (-ve =>into the incline)
By the way, this question is not calculus 3, but more mechanics, or physics. You have a better chance of getting answers if posted under "physics".
<span>The greatest common factor (GCF) of 24 and 48 is 24</span>
Answer:
6 in.
Step-by-step explanation:
You should plot the total distance traveled from the base camp on the x-coordinate while the elevation should be plotted on the y-coordinate.
<h3>What is a graph?</h3>
A graph simply refers to a type of chart which is commonly used to graphically represent data on both the vertical and horizontal lines of a cartesian coordinate (x-coordinate and y-coordinate).
<h3>How to plot this graph?</h3>
In this scenario, you would plot the total distance traveled from the base camp on the x-coordinate while the elevation of the camps would be plotted on the y-coordinate as shown in the image attached below.

#SPJ1
Answer:
42 should be in the blank.
Step-by-step explanation:
If you multiply 7/8 by 6, watch what happens...
7/8 *6 = 42/48
The denominators are the same, which shows how the equations are probably equal.
I know it might seem confusing because I'm not great at explaining, but I hope it helps! Have an awesome day c:
