Ignore above
your equation is 2(cosx)^2-3cosx+1=0
use quadratic formula to get results
you will end up with
cosx=1 or cosx=1/2
so, x=0 or x=pi/3
2(3n-4)
Divide the whole equation by 2
Answer:
Step-by-step explanation:
I assume the box is a rectangular figure
Volume, V=L*W*H
V=11*8*6=528 in^3
528*1/10=52.8 in^3
Answer:
y = -3x + 7
Step-by-step explanation:
First calculate the slope which I will assign the variable m
slope = m = (y2-y1)/(x2-x1)
m = (-8-1)/(5-2)
m = -9/3
m = -3
Next, using the slope we just found, pick either point and plug into the point slope equation: (I like the first point better so I am going to use that one)
y-y1 = m(x-x1)
y-1 = -3(x-2)
y-1 = -3x + 6
y = -3x + 7
You can just subtract them seperatly like this:
20-12=8
2/5-3/5= -1/5
Since its negative, you have to take 1 off of the final answer and put 4/5 so the answer is 7 4/5
Another way is making it a decimal
12 3/5= 12.6
20 2/5= 20.4
20.4-12.6= 7.8
7.8=7 4/5
