Answer:

  11.0 years

Step-by-step explanation:

The exponential function describing the population growth can be written ...

  population = (initial population)×(1 +growth rate)^years

If t represents the number of years, we can fill in the values to get ...

  18500 = 12000×1.04^t

Dividing by 12000 gives ...

  18500/12000 = 1.04^t

Taking logarithms, we have ...

  log(18500/12000) = t×log(1.04)

  t = log(185/120)/log(1.04) ≈ 11.037 ≈ 11.0

It will be 11.0 years until the population reaches 18,500.

Representing algebraic relationships in tables and graph. Graph each equation y=x+3
KatRina [158]

Answer:

Step-by-step explanation:

To graph this equation, start by plugging in different numbers for X and solve for Y.

For example: When x=0, y=0+3 ⇒ the coordinate is (0,3)

When x=1, y=1+3 ⇒ (1,4)

If you do this enough times, dotting each new coordinate then connecting them in a straight line, you will get your graph.

Ymorist [56]

Answer:

Question 2) 96 Question 3) 246

Step-by-step explanation:

Question 2:
The area of one side of the square is 4x4 which is 16 then you know a cube has 6 sides so 16x6 which is 96.


Question 3:
Well we know the two sides are squares with 3x3 which is 9 and then there are two so 9x2 which is 18

Then the front side with dimensions of 19x3 which is 57 and we know there are 4 sides so we do 57x4 which leads us to 228

Then we add 18 and 228 to find 246
