4.Darren can find the force, F, between two objects using the formula shown:F = G•mnr2where:•G is the gravitational constant.•m is the mass of the first object.•n is the mass of the second object.•r is the distance between the centers of the objectsRewrite the formula to create an equation for min terms of F, G, n and r

hard

step-by-step explanation:

(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

y - 25 = 2 ( x - 10 ) should be the answer
