Let the number of puppies his sister has be c
he has 4 more
Means if she had 3 he has having 7
if she is having 11 he is having 15
if she is having c he is having c+4
So the answer is c+4
Answer:
$136
Step-by-step explanation:
x = per hour
y = total profit
4 + 4 = 8
Equation:
y = 18x - 8
y = 18(8) - 8
y = 144 - 8
y = 136
The function that represents the growth of this culture of bacteria as a function of time is; P = 1500e^(1.0986t)
<h3>How to calculate Exponential Growth?</h3>
The formula for exponential growth is;
P = P₀e^(rt)
where;
P = current population at time t
P₀ = starting population
r = rate of exponential growth/decay
t = time after start
Thus, from our question we have;
4500 = 1500 * e^(r * 1)
4500/1500 = e^r
e^r = 3
In 3 = r
r = 1.0986
Thus, the function that represents the growth of this culture of bacteria as a function of time is;
P = 1500e^(1.0986t)
For the culture to double, then;
P/P₀ = 2. Thus;
e^(1.0986t) = 2
In 2 = 1.0986t
t = 0.6931/1.0986
t = 0.631 hours

Answer:
ok thanks
Step-by-step explanation:
Answer:
The answer is D.
Step-by-step explanation:
First, we take the info we know. We know that this of multiplication. That means we can rule out A and E.
Now, we need to take the definition of the associative property. The associative property means that you keep the same numbers, variables, and operations, but you switch the grouping. This means that the answer is D. This is because, on both sides of the equation, we keep the same numbers variables and operations. However, on one side we have 4 grouped with r, and on the other, we have 3 grouped with 4. We switched our grouping but kept the expression. This means that our answer is D.
