Find the length of RS.<br> A. 40 units<br> B. 8 units<br> C. About 6.3 units<br> D. About 2.8 units
Blizzard [7]

Given:

The two points on the graph are R(-2,-4) and S(-8,-6).

To find:

The length of RS.

Solution:

Distance formula: The distance between two points is

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Using the distance formula, the distance between R(-2,-4) and S(-8,-6) is

d=\sqrt{(-8-(-2))^2+(-6-(-4))^2}

d=\sqrt{(-8+2)^2+(-6+4)^2}

d=\sqrt{(-6)^2+(-2)^2}

d=\sqrt{36+4}

On further simplification, we get

d=\sqrt{40}

d=6.32455532

d\approx 6.3

Therefore, the length of AB is about 6.3 units. So, the correct option is C.

Two ships leave port at the same time. One travels north at 70 knots (that is, 70 nautical miles per hour), and the other west a
sergeinik [125]

Answer:

99miles is more likely correct

or 114miles as knots is usually higher mileage

Step-by-step explanation:

70^2 + 70^2 = c^2

sqrt 4900 + sqrt 4900 = c^2

sq rt 9800 = c^2 = 98.9949494

99 x 1.1507794480225 = 113.927165 = 114miles if converted to 80.6m/ph

70 Knots is equivalent to 80.554561361578 Miles/Hour. How to convert from Knots to Miles/Hour The conversion factor from Knots to Miles/Hour is 1.1507794480225. To find out how many Knots in Miles/Hour, multiply by the conversion factor or use the Velocity converter.

4/7 - x = 6/35 what is x? how do I determine the answer?
vivado [14]
4/7 - x = 6/35

You're trying to get x by itself, so you have to subtract 4/7 from both sides.

-x = 6/35 - 4/7

You need both of the fractions to the right of the equal sign to have the same denominator so that we could simplify them, so multiply 5/5 to -4/7.

-4 /7 × 5/5 = -20/35

So, our new equation is :

-x = 6/35 - 20/35

Simplify.

-x = -14/35

Divide both sides by -1.

x = 14/35

Divide by 7.

x = 2/5
