The law of cosines for this particular situation is b^2 = a^2 + c^2 - 2ac cosB.
Filling in what you know, you have b^2 = 25 + 49 - [2(5)(7)-.1908], which simplifies to b^2 = 74 - 69.8092 which gives you a b^2 value of 4.1908, but you have to take the square root of that so you get a side value for b of 2.05.
Answer:
8
Step-by-step explanation:
Let's set this up to see if we can simplify it a bit:
Notice we have 4 tens on top and 3 on bottom, so we can eliminate the bottom 3 altogether and leave just one on top. And we have 2 fives on the top and 3 on bottom, so we can eliminate the 2 on the top and leave one on the bottom. Now that looks like this:
10 divided by 5 is 2, and 2 cubed is 8
Y=3/2x+1. The slope is change in y I’ve ether change in x (rise over run). And the y intercept is (0,1).
Answer:
50 miles per hour!
Step-by-step explanation:
If 2 hours equal 100 miles, then 1 hour will be 50!
Hope this helped!
If it’s all 3 being chosen it’s 1/7 X 1/7 X 1/7 which is .002915 which would be a .29%
