Please help me!!!! precalc question
1 answer:
Step-by-step explanation:
1. Ampltiude is 1
The period is
is the period
The phase shift is 0
2. The Ampltiude is 2
The period is 2 pi
The phase shift is 1
3. The amplitude is 3
The period is 2 pi/3
The phase shift is -2
4.The amplitude is 2/3
The period is -10pi
The phase shift is 0
5. The Ampltiude is 1
The period is -2 pi
The phase shift is pi
6. The amplitude is 1/4
The period is -4pi
The phase shift is negative 2pi/3
7. The Ampltiude is 3
The period is 4
The phase shift is 8

D. x is greater than or equal to -8
Explanation:
The inequality given by the problem is:
In order to solve it, we must do the following steps:
- Multiply by 4 on both sides of the inequality:
- Change the sign of both sides: when doing this step, we must reverse the sign of the inequality:
So, the correct option is
D. x is greater than or equal to -8
Answer:
600 mph
Step-by-step explanation:
Given that,
Distance covered by ball, d = 5 miles
Time taken, t = 30 seconds
1 second = (1/3600) hour
Speed = distance/time
So, the speed of the ball is 600 mph.
