The answer is 5 and -5, because squaring a positive or negative number give the same value, so square rooting that number should give back those positive and negative value. THIS ONLY WORKS FOR WHEN THE SQUARE ROOT OR THE SQUARING IS AN EVEN NUMBER.

If the ship can travel to either dock, which dock would be closest? Explain your answer. Michael’s dock would be closer because

Greeley [361]

Answer : Michael’s dock would be closer because the angle opposite is smaller

Michael and Jacob are standing on two docks that are 20 miles apart. They are watching a ship that is out in the ocean. The angle between the dock and the line connecting Michael and the ship is 48°, and the angle between the other dock and the line connecting Jacob and the ship is 37°.

Explanation:

the angle between the other dock and the line connecting Jacob and the ship is 37°. The side opposite to angle 37 will be smaller. The distance between Michael and Ship will be smaller than Jacob and ship.

So Michael’s dock would be closer because the angle opposite is smaller.

Hey, I'm not sure if I'm wrong or not but wouldn't the answer be c divided by pi? or c/pi

dedylja [7]

Answer:

You are correct

It is C divided by PI

Step-by-step explanation:

c=pi x D

Using substitution method replace letters with numbers

12(c)=3(pi) x 4(d)

we want 4(d) the subject of the formula

4(d)=

12/3 =4

so it is 4(d)=12(c)/3(pi)

so D=C/PI

D is the midpoint of CE. E has coordinates (−9, −6), and D has coordinates (7, 2). Find the coordinates of C

Sav [38]

This problem is really easy. You set up the first coordinate and then the midpoint on the bottom

(-9 , -6)
(7 , 2)

Now there are 16 steps from -9 to 7, then you add 16 more to 7 and you get 23 for the x axis.

There are 8 steps from -6 to 2, now count 8 more steps, and you get 10 for the y axis.

The coordinates of C are (23 , 10)
