Step-by-step explanation:
Answer:
9 seconds
Step-by-step explanation:
d=-16t²+vt+h
The water level will be at 0 level (distance = 0)
0 = 16t² - 90t - 486
8t² - 45t - 243 = 0
(t - 9) (8t + 27) = 0
t = 9 or t = -27
since time should be a positive number, so t = 9 second
Answer:
6.9 to the nearest tenth.
Step-by-step explanation:
Use the external tangent - chord theorem:
AP^2 = CP * BP
AP^2 = 12 * 4 = 48
AP = √48
= 6.928
Since Location A has vaccinated 10 thousand people at the start of the month, then write 10 on the first row of the first colum.
Since they can apply vaccines at a rate of 20 thousand people per week, add 20 thousand to the value on each row (in thousand) to find the value of the next. Then, the column A will contain the following data:
0: 10
1: 30
2: 50
3: 70
4: 90
5: 110
6: 130
Similarly, place 60 thousand on the first row on the column B and ad 5 thousand each time:
0: 60
1: 65
2: 70
3: 75
4: 80
5: 85
6: 90
Don't forget to show the calculations on the answer. For column A:
10+20=30
30+20=50
... and so on.
For column B, start with 60 and add 5 each time.
