The answer is A : y=-1/5x+1 ..... I checked on desmos
Answer:
The sequence above is a geometric sequence
For an nth in a geometric sequence

where n is the number of terms
a is the first term
r is the common ratio
From the question
a = 45
r = 15 / 45
The explicit formula for the sequence is
U(n) = 45(1/3)^n-1
Hope this helps you
The estimate closest to an average person's weight is 80kg
<h3>How to determine the estimate?</h3>
The weights are given as:
8 kg, 80 kg and 800 kg
To answer this question, I will assume that a person means an adult
An adult that weighs 8 kg is very much under weight
Because the average weight of a person is around 60 to 90 kg
Hence, the estimate closest to an average person's weight is 80kg

The distances from Boston to New York and New York to Boston stayed the same. Going was 45mph and returning was 65mph. The average would just be the sum of the two, divided by 2
(45+65)/2 = 55mph average
