The answer is 540, you kind of have to cut the figure in different parts then do separate volumes for them then add both volumes together:)
Answer: option B.
Step-by-step explanation:
You can apply the elimination method:
- Multiply the first equation by -7 and the second equation by 3.
- Add both equations to cancel out the variable y.
- Solve for x
- Substitute x=-2 into any of the original equations ans solve for y. Then:
<span>-2b^2 -3b+14=0
(-2b - 7)(b - 2) = 0
hope it helps</span>
<span>ratio of their perimeters and the ratio of their areas would be </span>5:9 and 25:81
Answer:
The Riemann sum equals -10.
Step-by-step explanation:
The right Riemann Sum uses the right endpoints of a sub-interval:
where
To find the Riemann sum for with n = 5 rectangles, using right endpoints you must:
We know that a = -6, b = 4 and n = 5, so
We need to divide the interval −6 ≤ x ≤ 4 into n = 5 sub-intervals of length
Now, we just evaluate the function at the right endpoints:
Finally, just sum up the above values and multiply by 2
The Riemann sum equals -10
