Find a parametric representation for the surface. the part of the sphere x^2 + y^2 + z^2 = 64 that lies above the cone z = x^2 + y^2 . (enter your answer as a comma-separated list of equations. let x, y, and z be in terms of u and/or v.)

step-by-step explanation:

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week
