Answer:
3/5
Step-by-step explanation:
sin theta=opposite/hypotenuse
4/5=opposite/hypotenuse
therefore opposite=4 and hypotenuse=5
for adjacent
using pythagoras theorem
a^2+b^2=c^2
opposite^2 + adjacent^2 =hypotenuse^2
4^2 + adjacent^2 =5^2
16 + adjacent^2 =25
adjacent^2 =25-16
adjacent =
adjacent=3
cos theta=adjacent/hypotenuse
=3/5
therefore the value of cos theta is 3/5
Y = 3x + 48 where x is your number of years. I got 48 by multiplying 4 and 12 since there are 12 inches in a foot. (:
In the graph you can see the point are crossing Y -1 and x= 2,
x-y=xy
2-1=1
Y=1
Should look something like that
Answer:
y = 2/5x + 4/5
or
y = 2/5x +0.8, both mean the same thing
Step-by-step explanation:
Perpendicular line would mean that the line has to go through line m at a 90 degree angle.
The first thing I would do is look at the slope already given to us for line m and flip it around and make the negative fraction a positive one so it goes up.
-5/2x -> 2/5x
The next would be to find where the line would intercept on the y-axis. It already told us it will go through the point (3,2). So with the slope we already have, count 5 to the left and 2 down. At this point I plotted this entire thing in a graphing calculator. Anyways the answer:
y = 2/5x + 4/5
