Q1.The cost of $16.50 for the music was reduction of 12% on the original cost.

1 answer:

7 0

Q1) £16.50 x 1.12 = £18.48
Q2)

2+9+1= 12
3h 33m = 213m
213/12 = 17.75
2x17.75 = 35.5 (music)
9x17.75 = 159.75 (films)
1x17.75 = 17.75 (books)

So it’s 159.75 minutes for the films to download

A clown is juggling at a circus. The path of the ball is given by the parametric equations x=2 cos t+2 and y=3 sin t+3. In what

Masja [62]

We need to find the direction the ball is moving, so wee have this parametric equation, namely:

$\left \{ {{x=2cost+2} \atop {y=3sint+3}} \right.$

The graph of this equation is given in figure below. So, we well substitute some values of t in the equation:

If t = 0
x = 4 and y = 3
P0(4, 3)

if t = 1
x = 3.08 and y = 5.52
P1(3.08, 5.52)

if t = 2
x = 1.16 and y = 5.72
P2(1.16, 5.72)

So, as shown in the figure, the answer is B. <span>counterclockwise </span>
