The answer to 25. is A
and
to 26. is C (I'm not sure on this one but i think this is the answer)
We find the value of N₀ since we are provided with initial conditions.
The condition is that, at time t = 0, the amount of substance contains originally 10 grams.
We substitute:
10 = N₀ (e^(-0.1356)*0)
10 = N₀ (e^0)
N₀ = 10
When the substance is in half-life (meaning, the half of the original amount), it contains 5 grams. We solve t in this case.
5 = 10 e^(-0.1356*t)
0.5 = e^(-0.1356*t)
Multiply natural logarithms on both sides to bring down t.
ln(0.5) = -0.1356*t
Hence,
t = -(ln(0.5))/0.1356
t ≈ 5.11 days (ANSWER)
4*25= 100. There are 26 tables. At each of the 25 tables 4 people are sitting. Which means 100 people are sitting in complete tables of 4 people. That means that at the 26th table 3 people are sitting. 103-100= 3. Hope that helps. :)
Answer:
$13.60
Step-by-step explanation:
First let's find how much Gerry spends on lunch in 2 weeks (assuming she goes to school 5 days a week):
$1.25*10=$12.50
Now we find out how much she pays for the extra snack. Since in 2 weeks there are 2 Fridays then:
0.55*2=$1.10
Then we add these two together to get:
$12.50+$1.10=$13.60
Answer:
The answers in order are:
slope-intercept form
slope of a line
y-intercept
Step-by-step explanation:
These are the definitions of the terms.
y=mx+b is called slope-intercept form because it contains the slope (m) and y-intercept (b)
slope of a line is change in y over change in x (steepness) which is m
y-intercept is point line intercepts y-axis and is b
