A vine called the mile a-minute weed is known for growing at a very fast rate. It can grow up to 0.25 inches

jek_recluse [69]

Answer:

$\displaystyle =\frac{0.5\text{ ft}}{\text{day}}$

The weed grows at a rate of 0.5 feet per day.

Step-by-step explanation:

The weed grows at a rate of 0.25 inches per hour.

And we want to convert this rate into feet per day.

We have that:

$\displaystyle \frac{0.25\text{ in}}{\text{hr}}$

We knowt that there are 12 inches in one foot.

And since we want to cancel the inches, we can write our conversion factor as ft / 12 in.

We also know that there are 24 hours in one day.

And since we want to cancel the hours, we can write our conversion factor as 24 hr / day.

Hence:

$\displaystyle \frac{0.25\text{ in}}{\text{hr}}\cdot\frac{\text{ft}}{12\text{ in}}\cdot \frac{24\text{ hr}}{\text{day}}$

Multiply and cancel common terms. So:

$\displaystyle =\frac{0.5\text{ ft}}{\text{day}}$

The weed grows at a rate of 0.5 feet per day.

For any nonnegative real number.

frutty [35]

Answer:

Step-by-step explanation:

We know that $\sqrt{b}=b^{1/2}$ .

We also know that $(a^b)^c=a^{bc}$ .

We can combine these facts to get $(\sqrt{b})^2=(b^{1/2})^2=b^{1/2*2}=b^{1}=b$ .

So, the answer is $\boxed{A}$ and we're done!

<em>Note: the non-negative part or the equation comes from the fact that you assume the square root of a negative number doesn't exist. You will change this assumption later in the year, or in further years.</em>
