Estimate the volume of the solid that lies below the surface z = xy and above the following rectangle. r = (x, y) | 8 ≤ x ≤ 14, 6 ≤ y ≤ 10 (a) use a riemann sum with m = 3, n = 2, and take the sample point to be the upper right corner of each square. (b) use the midpoint rule to estimate the volume of the solid.

answer: huh

step-by-step explanation:

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
