Answer:
20
Step-by-step explanation:
Use the distance formula:
Answer:
-1/4
Step-by-step explanation:
Use the formula: a2 divided by a1. (a2/a1)
Plugging it in would look like this:
-6/24
-6/24 is equal to -1/4.

Answer:
C. (-2,2π/3)
Step-by-step explanation:
Given:
In the given plane, each line represents angles and the circles shows the radii. Now as full circle is of 360 degrees or 2π and there are 12 straight lines that means
every angle is π/6 apart (30 degrees).
As the given red point is on circle 2, this means the radii, r=2
and Ф=300 degrees or 5π/3
r=(2,5π/3)
but above is not given in the options.
Polar coordinates can have positive or negative theta and also have positive or negative radii. In case of negative radii the polar coordinate moves in opposite direction of the pole.
if we consider r=-2 then we have to move in opposite direction of pole of Ф=300 degrees or 5π/3 is 120 degrees or 2π/3.
hence r=-2 andФ=2π/3
Correct option is C:(-2,2π/3)!
Jo swims 12 laps in 7 minutes, and we have to find how many minutes it would take to complete 30 laps.
First, we have to figure out how many 12 laps are in 30 laps.
30/12 = 2.5
Since this is a proportion, we have to apply the same 2.5 to 7 minutes.
7 * 2.5 = 17.5 minutes.
It would take Jo 17.5 minutes to complete 30 laps.

Answer:
3. Simplifying
4 multiplication property of equality.
5. simplifying
Step-by-step explanation:
y/2 -21+21 = -15+21
To get to the next step we add -21+21 on the left and -15+21 on the right
We are simplifying on each side
Then we multiply by 2 on each side for the next step
We use the multiplication property of equality.
Finally we simplify in the last step
