Explanation Formula used: The volume of the frustum is given by the formula V = 1 3 π h ( r 1 2 + r 2 2 + r 1 r 2 ) or V = π h 12 ( d 1 2 + d 2 2 + d 1 d 2 ) where r 1 is the radius of the upper base, r 2 is the radius of the lower base, d 1 is the diameter of the upper base, d 2 is the diameter of the lower base and h is the altitude. Calculation: From the given figure, it is to be noted that the given solid object is a frustum with upper base of dimensions d 1 = 4 m and s = 6.7 m and a lower base of dimensions d 2 = 10 m and s = 6.7 m . Substitute the values d 1 = 4 m, d 2 = 10 m , h = 6 m and s = 6

Cylinders

A cylinder is a three-dimensional solid shape with two parallel and congruent circular bases, joined by a curved surface at a fixed distance. A cylinder has an infinite curvilinear surface.

Cones

A cone is a three-dimensional solid shape having a flat base and a pointed edge at the top. The flat base of the cone tapers smoothly to form the pointed edge known as the apex. The flat base of the cone can either be circular or elliptical. A cone is dr…

At most 28 of them are repeat offenders. c. At least 28 of them are repeat offenders. d. Between 22 and 26 (including 22 and 26) of them are repeat offenders.

(b) Find the (instantaneous) rate of change of y at x = 5. In the previous part, we found the average rate of change for several intervals of decreasing size starting at x = 5. The instantaneous rate of change of fat x = 5 is the limit of the average rate of change over the interval [x, x + h] as h approaches 0. This is given by the derivative in the following limit. lim h→0 - f(x + h) − f(x) h The first step to find this limit is to compute f(x + h). Recall that this means replacing the input variable x with the expression x + h in the rule defining f. f(x + h) = (x + h)² - 5(x+ h) = 2xh+h2_ x² + 2xh + h² 5✔ - 5 )x - 5h Step 4 - The second step for finding the derivative of fat x is to find the difference f(x + h) − f(x). - f(x + h) f(x) = = (x² x² + 2xh + h² - ])- = 2x + h² - 5h ])x-5h) - (x² - 5x) = ]) (2x + h - 5) Macbook Pro
