Answer:
C. About 22
Step-by-step explanation:
13.3 + 2.8 + 5.6
= 21.7
Since 21.7 is close to about 22, we can conclude that C is the final answer.
Answer:
The slope of this line would be undefined.
Step-by-step explanation:
In order to find the slope of any line, use the slope formula.
m(slope) = (y2 - y1)/(x2 - x1)
m = (3 - -1)/(-6 - -6)
m = (3 + 1)/(-6 + 6)
m = 4/0
Since we cannot divide by 0, then we know the slope is undefined.
2x-5=95 due to the alternate interior angles thm so you just add 5 to 95 to get 2x=100 then divide by 2 to get x=50!
Answer:
Step-by-step explanation:
Begin by squaring both sides to get rid of the radical. Doing that gives you:
Now use the Pythagorean identity that says
and make the replacement:
. Now move everything over to one side of the equals sign and set it equal to 0 so you can factor:
and then simplify to
Factor out the common cos(x) to get
and there you have your 2 trig equations:
cos(x) = 0 and 1 - cos(x) = 0
The first one is easy enough to solve. Look on the unit circle and see where, one time around, where the cos of an angle is equal to 0. That occurs at
The second equation simplifies to
cos(x) = 1
Again, look to the unit circle and find where the cos of an angle is equal to 1. That occurs at π only.
So, in the end, your 3 solutions are
graph b because only a and b are linear associations and only b and c are negative
