Answer:
580
Step-by-step explanation:
I wanted to use the Pythagoras theory but I noted that they've given us the hypotenuse which is 8.6 they have already given us the height is 7 and the base is 5 when you use the Pythagoras theory you'll find that there hypotenuse is 8.6 that's why I wrote forget it there's no need of finding the base and the height for the other triangle just transfer 7 and 5 then calculate the volume I guess I got the answer is 580 hope it helps you good day.
Answer:
(-9, 6)
Step-by-step explanation:
It's all about pattern matching.
A circle centered at (h, k) with radius r has the equation ...
(x -h)^2 + (y -k)^2 = r^2
Comparing this pattern to the equation you have, you can see that ...
- h = -9
- k = 6
- r = 10
Then the center is (h, k) = (-9, 6).
A suitable calculator finds the determinant to be ...
... B. -203
_____
This can be calculated by hand by copying the first two columns to the right of the given matrix, then forming the sum of products of the downward diagonals and subtracting the sum of products of the upward diagonals.
... (-4)(3)(-5) +(-4)(-5)(-5) +(-3)(3)(2) -(-5)(3)(-3) -(2)(-5)(-4) -(-5)(3)(-4)
... = 60 -100 -18 -45 -40 -60
... = -203
