Use a calculator to find the decimal equivalents.
Then comparing the numbers is easy.
The answer is 50%
if you list out the possibilities, you get
(H being heads, T being tails)
HHH <- 3 heads
HHT <- 2 heads
HTH <- 2 heads
HTT
THH <- 2 heads
THT
TTH
TTT
we counted 4 of them to have at least 2 heads out of the 8 possibilities
4/8 = 1/2 which is 50%
Multiply 9 and 5 and you get 45.
Compounded once a year: A=P(1+r)^t
2500=500(1+0.095)^t
1.095^t=5
because the unknown number is an exponent, use log to find the unknown:
log(1.095^t)=log5
tlog1.095=log5
t=log5/log1.095
use your calculator, t=17.734
so this person is about 28 years old.

Answer:
25 (ft/s)
Step-by-step explanation:
The "rate of change" is taken to mean the "rise" divided by the "run". Here, adjacent points differ in their y-value by 25 ft and their x-value by 1 second.
The rate of change is ...
rise/run = (25 ft)/(1 second) = 25 ft/second
Usually, we're just interested in the numerical value: 25.

<em>Additional comment</em>
The graph is mis-labeled. It is not showing "rate of ascent." It is showing height as a function of time. The "rate of ascent" is the <em>slope</em> of the line on the graph, not its <em>value</em>.
