Answer: C
Step-by-step explanation: With inverse equations, you switch y and x (y=f(x)) and undo/reverse the steps towards x.
1. Multiply by 3
2. Add 2
Equation by itself
0. x
1. 3(x)
2. 3(x+2)
So C/D=.34 And D=.11, now just plug D into the first equation.
C/.11=.34 Divide by .11
C=3.09090909
Now this rounded two decimal places is 3.09!
Hope this helps
Answer:
18.7 feet far
Step-by-step explanation:
Based on the information given we can conclude that our set up will be a Right triangle (i.e. one angle is 90°), where the hypotenuse will be denoted by the guy wire of
and angle of 21° is the angle formed between then hypotenuse and the base (i.e. ground).
Thus we want to find the base length (lets call it
) of this triangle, so we can use trigonometry as we have one angle and the hypotenuse, as follow:

So the base is approximately 18.7 feet far from the tree of the anchored wire.
see the attached figure to better understand the problem
Step 1
<u>Find the number of pages printed on an Apricot printer </u>
we know that
The speed of an Apricot printer is 8ppm
so
in 4.5 min
Carlos print
4.5*8=36 pages
step 2
<u>Find the time it takes Carlos to print the same amount of documents on a sure fire printer printer</u>
we know that
The speed on a sure fire printer is 12ppm
so
Divide the total of pages by the speed of the printer
36/12=3 minutes
therefore
<u>the answer is</u>
3 minutes
Form a right angle triangle joining both given points to the origin, we get:
Perpendicular = 2 ( distance is always positive)
Base = 4 ( same logic)
Applying Pythagorus theorem
Hypotenuse = root of ( perpendicular squared + base squared)
Hypotenuse = root of 20 = 2 * root 5
Using x instead of theta
Sin x = perpendicular/hypotenuse
Cos x = base/hypotenuse
Sin x = -1/ root 5
Cos x = -2/ root 5
High probability of this answer being wrong.
Double check recommended.
