Please just type this on a calculator, all you need to do is press cos, and then (7/19).
Make sure that you have the correct mode. (deg or rad)
-5+-5=10, 10=0, but that's false. Therefore, it's not a solution.
There aren't any numbers that add up to -4 and multiply to 24, so it can't be factored.
You could use the quadratic formula to solve for x, though.
1km=1,000 meters
5km=5,000 meters
1 hour=60 minutes=3,600 seconds
You know what to do next.
How do you get the square root sign? I tried looking for it everywhere but never found it.
It's simple: multiply 17 by 70.
Given the radius and height, the formula for the surface area of a cone is $${\mathtt{\pi}}$$r[r+(sqrt of h^2+r^2).
h for height, r for radius.
Plugging in the values: we get 10$${\mathtt{\pi}}$$[10+(sqrt200)]
Can you finish it from here?
You could factor out 5x to get 5x(a-5b).
It can also mean the square root of x, since (x)^1/2 has a denominator of 2 and a numerator of 1.
V=BH, b for base and h for height.
So, just do the following operation: 3*8*10
