Answer:
I believe 57
Step-by-step explanation:
7 trees per 3 hours
6 hours = 14 trees
plus the 2 hours which I'm assuming 5 to 4 trees
so you multiply 19 trees per day
19 x 3 = 57 if I'm wrong please correct me :)
Answer:
It returns the angle whose cosine is a given number.
Step-by-step explanation:
For every trigonometry function, there is an inverse function that works in reverse. These inverse functions have the same name but with 'arc' in front. (On some calculators the arccos button may be labeled arccos, or sometimes cos-1.) So the inverse of cos is arccos etc. When we see "arccos x", we understand it as "the angle whose cosine is x"
cos30 = 0.866 Means: The cosine of 30 degrees is 0.866
arccos 0.866 = 30 Means: The angle whose cosine is 0.866 is 30 degrees.
Use arccos when you know the cosine of an angle and want to know the actual angle.
Answer:
y(x)=2x^3-6x^2+ax+b, a and b are constants
Step-by-step explanation:
d2y/dx2=12x-12, integrating both sides we get
dy/dx=6x^2-12x+a, where a is the integration constant.
Again integrating both sides, we get
y(x)=2x^3-6x^2+ax+b, where b is the integration constant
9.945*10^30 Kg - 1.7901*10^32 Kg
This is on average what the mass of a black hole.
4/5=87+2(55:10)-33 so that will be your answer if you simplify it
