For the given central angle, determine the distance traveled along the unit circle from the point (1, 0). 210 degrees a. 3.67 un
Black_prince [1.1K]

Answer:

3.67 units

Step-by-step explanation:

The central angle is at the point (0,0).

Then it's at the point (1,0)

Then it moved 210 degrees.

Let's bear in mind that we start moving the degree from it's current position.

So moving 210 degrees is moving 180 degrees plus 30 degrees.

Moving 180 degrees I like transforming linearly.

Now the location is at (-1,0)

But the distance covered will be

= 2πr*210/360

r = 1

= 2*3.142*1*(210/360)

= 6.144*0.5833333

= 3.67 units

Solve the system of equations using elimination.
Dmitrij [34]

So just plug in the numbers (x,y) into the equations.

A) (7.5, -5)

2(7.5) -5 = 10

15 - 5 = 10 yup, this works.

Let's see if it works for other equation.

-2(7.5) + 2(-5) = 5

-15 - 10 = 5 nope, this does not work.

B) (-2.5, -5)

2(-2.5) - 5 = 10

-5 - 5 = 10 nope, doesn't work

Since it doesn't work we don't need to try for other equation.

C) (2.5, 5)

2(2.5) + 5 = 10

5 + 5 = 10 yup, this works.

Now the other equation.

-2(2.5) + 2(5) = 5

-5 + 10 = 5 and this works.

So the solution to this set is answer choice C

jenny`s mom says she has an hour before it's bedtime. Jenny's spends 3\5 of hour texting a friend and 3\8 of the remaining time
laiz [17]
First you'll need to get the same denominator. So instead of 3/5 and 3/8 you'll have 24/40 and 15/40. Now that we've changed the value of the denominator, the 40/40 will now represents the 1 hour that Jenny has before bedtime. So you add 24/40 and 15/40 and get 39/40. 39/40 stands for the time that Jenny has already spent brushing her teeth and texting her friend all together. Since the 1 hour is 40/40 subtract 39/40 from it to get 1/40. 1/40 is equal to the rest of the time Jenny spends reading or 1.5 minutes.
