Answer:
9
Step-by-step explanation:
I think it is d I am not sure thought I am sorry
465 is the answerrrrrrrrrrrrrrrrrrrrr
The area for a rhombus is
. We have the area and the length of one of the diagonals, so we fill in accordingly:
. 8x/2 = 4x, so now we have 16=4x. Divide both sides by 4 to get x = 4. It's not longer than 8, but it's the length of the other diagonal, for sure.
Answer:
y = ± [ √(x+4) ] / 3
Step-by-step explanation:
1) To find the inverse of the function y = 9x2 – 4, exchange the variables x and y, and then solve for the new y.
2) Exchange of the variables: y = 9x^2 – 4 → x = 9y^2 – 4
3) Solve for y:
=> 9y^2 = x + 4
=> y^2=> y = ± [ √(x + 4) ] / 9
= > y = ± [ √(x + 4) ] / 3
