20000=1650e^(.5t)
12.121212=e^(.5t)
Ln(12.121212) = ln(e^(.5t))
2.49495 = .5t
4.98 = t
Rounding it will take approximately 5 years for the pop. to reach 20,000
Answer:
1The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y).
Answer:
150 m at 10 m/s
350 m at 50 m/s
Step-by-step explanation:
x + y = 500
x/10 + y/50 = 22
~~~~~~~~~~~~~~~~~
x + y = 500
5x + y = 1100
~~~~~~~~~~~~~~~~
x + y = 500
-5x - y = -1100
-4x = -600
x = 150
y = 350
Answer:
20.54%
Step-by-step explanation:
the first thing to know the percentage change, is to notice if the average increased or decreased, if it was initially 73 and then 88, we can say that increase, therefore the change is positive, now to calculate the exact change we must calculate the quotient of these numbers:
88/73 = 1.2054
which means that 0.2054 is the proportion of increase, to pass it to a percentage we must multiply by 100, that is:
0.2054 * 100 = 20.54%
which means that the percentage change was 20.54%
