Let c be the circle in the xy plane centered at (5,0) with radius 2, and let s be the resulting surface in r3 when you rotate caround the y axis. (a) draw a picture of s. (b) find an equation for the tangent plane to s at the point (3v2, 3,3v2). (c) find the surface area of s.

step-by-step explanation: the answer for wha if rt is 10 centimeters long, and wha is st? it’s 6

363 square inches

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242

363

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."

a             it is the sum of the initial amount and the additional amount after d days.
