Answer:

  (a)  1/2

Step-by-step explanation:

The coordinates of the point of intersection of the terminal side of angle α with the unit circle are ...

  (x, y) = (cos(α), sin(α))

When α = 60°, the x-coordinate of the terminal point is cos(60°) = 1/2.

Midpoint formula is (  (x₁+x₂) / 2,  (y₁+y₂) / 2  )

So that would be (  (9-1) / 2,  (8-2) / 2  ) = (  8 / 2,  6 / 2  ) =  (4, 3)

Final answer: (4, 3)

What are the coordinates of the image of Q for a dilation with center (0, 0) and scale factor 1/2?
Amanda [17]
The answer would be D. (2,2)
Since the scale factor is 1/2, all you have to do is multiply 1/2 by each of x-coordinate and y-coordinate of Q.
Multiplying by 1/2 is the same as dividing by 2, so you divide the x and y coordinates of Q to get the dilation image of Q as (2,2).

Three friends are travelling by aeroplane and want to pay as little as possible in total for their luggage.
In-s [12.5K]

Answer:

B.25$

Step-by-step explanation:

to make the money less one of the freinds will carry 9kg and the other 12 kg the last one carries the left luggage weighing 7kg and 6kg which add up to 13kg.

the first freind won't pay anything as he is passing 9kg luggage

the second will pay : 12-10 =2 so 2kg*5$=10$

the last freind will pay 13-10=3 so 3kg*5$=15$

to find the total money the pay we will add 10$ and 15$ which became 25$.

hope this helped.

Mrs. Jackson earned a 500 bonus for signing a one-year contract to work as a nurse. Her salary is 22 per hour. If her first week
jekas [21]
Ok so your first step is to make this an equation
she gets paid x amount per hour and she works for 22 hours
so 22x plus her bonus
22x + 500 =1204
so now solve the equation
subtract both sides by 500
22x +500 =1204
-500 = -500
to get
22x = 704
now divide both sides by 22
x = 32
