Answer:

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

$\sqrt{-25}=5i$

Step-by-step explanation:

i is an imaginary unit, this means

$i^2=-1$

Rewrite -5 as $5\cdot (-1)=5\cdot i^2,$

then

$\sqrt{-5}=\sqrt{5i^2}=\sqrt{5}\cdot \sqrt{i^2}=\sqrt{5}\cdot i=i\sqrt{5}$

Rewrite -25 as $-25=25\cdot (-1)=25\cdot i^2,$

then

$\sqrt{-25}=\sqrt{25\cdot i^2}=\sqrt{25}\cdot \sqrt{i^2}=5\cdot i=5i$

What is the slope intercept form of the equation of 6x+5y=-15

Soloha48 [4]

Slope intercept form is $\sf y=mx+b$ , where 'm' is the slope and 'b' is the y-intercept.

$\sf 6x+5y=-15$

Subtract 6x to both sides:

$\sf 5y=-6x-15$

Divide 5 to both sides:

$\boxed{\sf y=-\dfrac{6}{5}x-3}$

You give tours on the Great Lakes and talk about points of interest. A lighthouse typically has 2 beacons that rotate together—b

tatiyna

Since the beacons rotate together, the angular speed is constant.

From the time you see the first beacon, you have to wait for the lighthouse to make 120°, i.e. 1/3 of a whole turn.

So, if T is the time it takes for the lighthouse to make a whole turn, the interval between the first and the second beacon is T/3.

The interval between the second and third beacon is the amount of time it takes to the lighthouse to make the remaining 2/3 of a turn, so that you'll see the first beacon again. So, this time is 2T/3

So, the ratio is

$\dfrac{2T}{3}\div\dfrac{T}{3}=\dfrac{2T}{3}\cdot\dfrac{3}{T}=2$

So, the time between the second and third beacon is twice as much the time between the first two.

Carmen lives in Maine and pays 5% in sales tax. She just bought $70 in

galina1969 [7]

Answer:

The correct answer is option A.

Step-by-step explanation:

Let's start by analyzing the information we have.

We know that Carmen pays 5% tax on everything she buys, and has made a purchase of $ 70.

But they also tell us that there is $ 25 of that purchase that will not be charged with taxes.

Therefore, what will be charged with taxes will be:

70-25 = 45

Now we must know how much is 5% of 45 and that we can find out by multiplying 45 by 0,05:

45.0,05 = 2,25

Now that we know that the tax was 2.25, we just have to add it to the total purchase to find out how much Carmen paid:

2.25 + 70 = 72.25

Therefore, the total value of the purchase is 72.25.
