Answer:
50.24
Step-by-step explanation:
r = d/2
r = 8/2
r = 4
Area of a Circle:
A = πr²
Work:
A = πr²
A = 3.14(4²)
A = 3.14(16)
A = 50.24
Answer: hole at x = 0, asymptotes at x = -2 and x = -3
<u>Step-by-step explanation:</u>
=
=
x ≠ 0 ---> the x cancels out so this is a hole
x + 2 ≠ 0 ---> x ≠ -2 ---> asymptote at x = -2
x + 3 ≠ 0 ---> x ≠ -3 ---> asymptote at x = -3
Ok so,
160 divided by 7.75 = 20.65
therefore,
150 divided by 20.65 = 7.265625 gallons or 7.27 (2 d.p)
I know the answer to 17 is the measure of each angle is 45° but i’m not sure about the rest sorry
Yes. Conceptually, all the matrices in the group have the same structure, except for the variable component . So, each matrix is identified by its top-right coefficient, since the other three entries remain constant.
However, let's prove in a more formal way that
is an isomorphism.
First of all, it is injective: suppose . Then, you trivially have , because they are two different matrices:
Secondly, it is trivially surjective: the matrix
is clearly the image of the real number x.
Finally, and its inverse are both homomorphisms: if we consider the usual product between matrices to be the operation for the group G and the real numbers to be an additive group, we have
