Elapsed time = half-life * log(beginning amount / ending amount) / log (2)
elapsed time = 5,600 * log (100 / 8) / log (2)
elapsed time = 5,600 * log (12.5) / log (2)
elapsed time = 5,600 * (1.096910013 / 0.30102999566)

Answer:
The set of Real numbers
Step-by-step explanation:
x² + 4 is a parabola with the lowest point on the y-axis is 4 and continues up
-x² + 4 is a parabola with the highest point on the y-axis is 4 and continues down.
The range is the distance traveled on the y- axis.
All real numbers.
Answer:
y=7/10+3/10
Step-by-step explanation:
Answer:
A. IV
Step-by-step explanation:
The figure is congruent, but rotated. Additionally, the figure is rotated/on point (4,4).
The <em><u>correct answer</u></em> is:
Explanation:
An exponential function is of the form
, where a is the initial population, b is 1 plus the amount of yearly change, and x is the number of years.
For our problem, a, the initial population, is 1500.
The yearly change is 6.3%; 6.3% = 6.3/100 = 0.063. Since it is decreasing, this is negative; 1+(-0.063) = 0.937.
We use t as the number of years.
This gives us
