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
direction is the ball moving?
A. up and to the right
B. counterclockwise
C. down and to the right
D. clockwise
1 answer:
We need to find the direction the ball is moving, so wee have this parametric equation, namely:

The graph of this equation is given in figure below. So, we well substitute some values of t in the equation:
If t = 0x = 4 and y = 3
P0(4, 3)
if t = 1x = 3.08 and y = 5.52
P1(3.08, 5.52)
if t = 2x = 1.16 and y = 5.72
P2(1.16, 5.72)
So, as shown in the figure, the answer is
B. <span>
counterclockwise </span>

Answer:
Answer is after 20 miles
Step-by-step explanation:
10 +2.5x = 3x
10 = 3x-2.5x
10=0.5x
10/.5=x
x=20
At 20 miles they both have a cost of 60

Answer:
38°
Step-by-step explanation:
Complementary means that they add up to 90
So then to find the measure of angle 2, subtract the measure of angle 1 from 90.
90-52=<u>38</u>
Answer:
2400 words
Step-by-step explanation:
80 = 2 min
60min ÷ 2min = 30min
30 × 80 = 2400 words
So area is base x height:
5(x+2)=20
5x+10=20
5x=10
x=2
