Please take just a few seconds longer and write "inverse cosine" as either:
arccos x or
-1
cos x or
cos ^(-1) x
A is true, since for any given x in [0, pi], there is exactly one associated y-value.
C is false. For one input (x) value, there is more than 1 associated y-value.
If every inch is 200 miles just do 200 times 7 to get the answer of 1400 miles
We have been given the matrix m as m = [874][205].
We can rewrite this matrix as
Now, we need to the find 
It means we need to find the entity that is present in the first row and the second column.
From the above matrix, we can see that 7 is in the first row and the second column.
Therefore, we have
Answer:
x^3 - 1
Step-by-step explanation:
(x^2 + x + 1) (x - 1)
Here we have to use the distributive property.
(x^2 + x + 1)x -1(x^2 + x + 1)
Now distribute x and -1 inside the parenthesis, we get
x^3 + x^2 + x -x^2 - x - 1
Now we have to simplify the like terms.
x^3 + x^2 -x^2 + x - x -1 [x^2 - x^2 =0; x -x = 0]
= x^3 - 1
The answer is x^3 - 1
Thank you.
The formula to find the area of a circle is pi x radius^2.
pi = 3.14 (in this case)
radius = 6
6^2 (6 x 6) = 36
36 x 3.14 (radius^2 x pi) = 113.04
So, the area of a circle with radius 6 cm is 113.04 cm.
