Ok so B is 78 - 26 = x
X is your answer
Answer:
-2/7 0r 2/-7 or the negative sign is in the middle
Step-by-step explanation:
(-3/4)(-4/7)= 3/7
3/7 x -2/3= -2/7
Answer:
316,912,650,057,057,350,374,175,801,344
Step-by-step explanation:
You can see that this sequence is geometric so you need to know the geometric sequence which is
and if you plug in every thing you get
=
which would be
which is 316,912,650,057,057,350,374,175,801,344
Answer:

Step-by-step explanation:
<u>Functions</u>
In a function, an independent variable, let's call it x is related to a dependent variable y and it can be expressed as:
y = f(x)
Let's consider the functions given in the question, where the equation that represents a company's yearly sales is:

And the equation that represents the same company's yearly expenses is:

The company's profit function P(x) can be found as the difference between S(x) and E(x), thus:

Operating:

Simplifying, the profit function for this company is:

Answer:
It will take about 7.3 years for his money to triple.
Step-by-step explanation:
Identify the variables in the formula.
A = 150,000
P = 50,000
r = 0.15
t = ?
A = Pe^rt
Substitute the values into the formula.
150,000 = 50,000e^0.15*t
Solve for t. Divide each side by 50,000.
3 = e^0.15*t
Take the natural log of each side.
ln 3 = ln e^0.15*t
Use the power property and then simplify.
ln 3 = 0.15*t ln e
ln 3 = 0.15-t
Divide each side by 0.15.
(ln 3)
/(0.15) = t
Approximate the answer.
t ≈ 7.3
