assuming the growth rate stays constant at 1.2%, how many doublings would take place in a 500- year period?

Juliette [100K]

9514 1404 393

Answer:

8.6

Step-by-step explanation:

The growth factor per year is 1.012, so in 500 years is ...

1.012^500

The number of doublings is the solution to ...

2^n = 1.012^500

Taking logarithms, we have ...

n·log(2) = 500·log(1.012)

n = 500·log(1.012)/log(2) ≈ 8.6046

About 8.6 doublings will take place in 500 years.

Find the slope of the line passing through the points D (10, 8) and E (-4,4)

RUDIKE [14]

Answer:

Slope=2/7

Step-by-step explanation:

Slope=rise/run

$rise = 8 - 4 = 4 \\ run = 10 - ( - 4) = 14 \\ slope = \frac{4}{14} = \frac{2}{7}$
