WHich choice is equivalent to the expression below? √-125

olasank [31]

Answer:

Final simplified form is $5\sqrt{5}i$

Step-by-step explanation:

We have been given an expression $\sqrt{-125}$

Now we need to simplify $\sqrt{-125}$ and check which choice matches with simplified form of $\sqrt{-125}$ .

You missed to provide the choices but still we simplify that.

$\sqrt{-125}$

$=\sqrt{-5*5*5}$

$=5\sqrt{-5}$

When there is negative sign inside square root then we replace that by "i" iota.

$=5\sqrt{5}i$

Hence final simplified form is $5\sqrt{5}i$

algol [13]

The parking lot charges $2 for the first hour plus 50 cent for each additional half hour or part thereof. What is the total char

Rasek [7]

The equation for this would be y=.5x+2. Now, in that time period, you will be parked there for 2 1/2 hours. Then figure out how many half hours are left in the 2 1/2 after the first hour is taken out. There are 3 half hours left. Now, you can plug that into your equation to figure out how much you will be charged. y=.5(3)+2 That becomes y=1.5+2. Then, that becomes 3.5. So, you will be charged $3.50. I hope that helps! :)
