The intensity of a light in lumens is the product of the brightness in lumens per square inch and the surface area of the sphere with a radius equal to the distance to the source in inches. The function L(D)=2.2(4*pi*D^2) can be used to represent a particular light’s intensity. What does the constant 2.2 in L(D) represent?
the intensity of the light
the distance to the source
the brightness of the source
the formula for surface area

hi im bob : l

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
