What is the slope of any line perpendicular to y=-1/3x+22
STatiana [176]
Answer:
The slope of any line perpendicular to the given line is 3

Explanation:
The general form of the linear line is:
y = mx + c where m is the slope
The given line is:
y = -1/3 x + 22
Comparing the given line with the general form, we will find that:
slope of the given line (m1) is -1/3

Now, for any two lines to be perpendicular, the product of their slopes should be equal to -1.
This means that:
m1 * m2 = -1
We have m1 = -1/3
Therefore:
-1/3 * m2 = -1
m2 = 3*1
m2 = 3

Hope this helps :)

Camp tent has a center pole 5 feet high. The sides of the tent make an angle of 55 degrees with the ground. How wide is the tent
Sphinxa [80]

To answer this problem, you need to use SOHCAHTOA.  The pole, the tent, and the ground form a right triangle.  One leg is equal to 5.  The top angle is 55.  You need to find length of the other leg, so use tangent.  

tan55=O/5

O=0.4375

Double this to find the total width of the tent.  0.4375*2=0.875

0.875 (rounds to 1) feet

Hope this helps!!
