Question 12 1 pts If the population of a country is reported in the year 1990 as 471.56 million and in the year 2000 as 492.53 m
I am Lyosha [343]

Answer:

  526.39 million

Step-by-step explanation:

The exponential equation can be written as ...

  p(t) = 471.56(492.53/471.56)^(t/10)

Then p(25) ≈ 525.75 . . . . million

__

The closest answer choice is 526.39 million.

__

<em>Comment on the answer choice</em>

Reverse-engineering the answer, we find it was computed using the exponential equation ...

  p(t) = 471.56e^(0.0044t)

  p(25) = 471.56·1.116278 ≈ 526.39

The k factor in the exponent is <em>inappropriately rounded</em> from 0.004350903. You cannot use a 2-significant-figure constant to arrive at an accurate 5-significant-figure answer.

I need help on what to say
garik1379 [7]
Part A: 75 and 8 are both coefficients in this case since both numbers are in front of a variable. D and W are two variables in this expression since they are letters that represent unknown numbers. 25 is the constant since that number does not change.

Part B: If Javier works for 5 days and installs 48 windows, he earns $784.
75d+8w+25
75(5)+8(48)+25
375+384+25
784

Part C: If Javier receives $40 for snacks instead of 25, the constant would change since 25 was the constant to begin with. The rest of the expression would stay the same. The new expression would look like this: 75d+8w+40.

I hope this was helpful.
