Answer: 60 in
Step-by-step explanation:
if the image is 3 times bigger, the length and width become...
4 in * 3 = 12 in. length
6 in * 3 = 18 in. width
so the perimeter is
12 * 2 + 18 * 2 = 60 inches!
We have to find the exact value of: arc cos ( sin ( π /6 ) ).
We know that:
sin ( π/6 ) = sin 30° = 1/2
Arc cos is the inverse function of cosine.
arc cos ( 1/2 ) = 60° = π/3
We assume you mean
.. f(x) = -3*x^3 -2
.. g(x) = -3*x^-3
Then
.. f(-3) = -3*(-3)^3 -2 = -3*(-27) -2 = 81 -2 = 79
.. g(4) = -3*4^-3 = -3/64

It is helpful if you use ordinary lower-case letters for variables (except in some formulas where upper-case letters are used). The symbol "×" is used to signify multiplication, so leads to confusion when you try to use it for a variable. In plain text, the exponentiation operator is a caret (^), so x^2 means "x squared", for example. If the exponent is supposed to include an arithmetic operation, then it needs to be enclosed in parentheses, x^(3y-4), for example.
Answer:
11/18
Step-by-step explanation:
divide the numerator and denomonater by the GCD, whic is 6.
then you would get the reduced fraction of 11/18
