He would save 70 cents because .10 x 7 = .7
and .7 x 100 is 70

Solve: In 2x + In 2 = 0<br> DONE

pychu [463]

Answer:

$x=\frac{1}{4}$

Step-by-step explanation:

We can use some logarithmic rules to solve this easily.

<em>Note: Ln means $Log_e$ </em>

<em />

Now, lets start with the equation:

$ln(2x) + ln(2) = 0\\ln(2x) = -ln(2)$

Writing left side with logarithmic base e, we have:

$Log_{e}(2x) = -ln(2)$

We can now use the property shown below to make this into exponential form:

$Log_{a}b=x\\means\\a^x=b$

So, we write:

$Log_{e}(2x) = -ln(2)\\e^{-ln(2)}=2x$

We recognize another property of exponentials:

$a^{bc}=(a^{b})^{c}$

So, we write:

$e^{-ln(2)}=2x\\(e^{ln(2)})^{-1}=2x$

Also, another property of natural logarithms is:

$e^{(ln(a))}=a$

Now, we simplify:

$(e^{ln(2)})^{-1}=2x\\(2)^{-1}=2x\\\frac{1}{2}=2x\\x=\frac{\frac{1}{2}}{2}\\x=\frac{1}{4}$

This is the answer.

A graduate school plans to increase its enrollment capacity by developing its facilities and the programs it offers. Their enrol

kap26 [50]

Answer:

4.4 years

Step-by-step explanation:

Next time, please share the answer choices.

In this case, the beginning enrollment capacity was 120. The rate of increase was 3.00, the terminal enrollment cap 3,240. We let t represent the number of years:

3,240 students = (120 students)(3.00)^t

We need to solve this for t, the number of years required before enrollment will hit 3,240 students.

Solve 3240 = 120(3)^t for t:

Divide both sides by 120, obtaining 27.

Then we have

127 = 3^t

Logarithms are the best tool to use here to find t. Take the natural log of both sides:

log 127 = t log 3. Solving for t: t = (log 127) / (log 3), or t = 2.104 / 0.477 = 4.41

Thus, starting at 120 students, enrollment reached 3,240 students in 4.4 years.

How to complete a coordinates table

lutik1710 [3]

. . .

What Is It?

Coordinate Graphing

Coordinate graphing sounds very dramatic but it is actually just a visual method for showing relationships between numbers. The relationships are shown on a coordinate grid. A coordinate grid has two perpendicular lines, or axes, labeled like number lines. The horizontal axis is called the x-axis. The vertical axis is called the y-axis. The point where the x-axis and y-axis intersect is called the origin.
