When the decrease in velocity (the acceleration) is uniform, the average velocity is [Initial velocity - Final velocity]/2
We know tha the initial velocity is 0.96 rev / sec and the final velocity is 0,
Then, the average velocity is [0.96 / 2 ]rev /sec = 0.48 rev/sec.
Also, by defintion,
average velocity = number of rev / time,
From which, number of rev = average velocity * time
So, number of rev = 0.48 rev/sec * 2.4 min * 60sec /min = 69.12 rev
Answer: 69.12 revolutions
Answer:
Step-by-step explanation:
First, determine where the quantity inside the absolute value bars is negative and where it is positive for example, So that's 6 times 8 minus 6 times negative 1. Okay and so this will be 48. Minus negative 6 which is 48 plus 6 which is 54 which is the answer.
The discriminant of ff is given by:
b^2-4ac=24^2-4 (multiply)3(multiply)48=576-576=0
2
−4ac=24
2
−4⋅3⋅48=576−576=0.
How many real number zeros does ff have?
Since the discriminant of ff is \green{0}0, ff has 11 distinct real number zero. Therefore, the graph of ff touches the xx-axis once. The graph of ff is shown below
Step-by-step explanation:
Write the highlighted digit's place and value.
3. 567; ones place 4. 6,327; thousandth place
5. 9,325; hundredth place 6. 8,281; tenth place
Write each number in standard form.
7. 5,000 + 500 + 3; 5,503 8. 2,000 + 300 + 20 + 9; 2,329
9. 4,000 + 600 + 8; 4,608 9. 9,000 + 300 + 70 + 2; 9,372
11. 1,221
We know Sierra has the same numbers in the thousandth and ones place, so keep does numbers: 1,?2?
It also has two more hundreds and 3 fewer ones place: Take the original number; 1,024 (Make sure you keep the numbers) into a equation; (1024+200)-3. First Add as it's in the ( ), then subtract, 1,221

X = 18
Steps:
Remove the parenthesis...
4x-6+x = 12+4x
Then cancel out 4x...
-6+x = 12
Then regroup the terms...
x - 6 = 12
Add 6 to both sides...
x = 12 + 6
Then you get...
x = 18
Hope this helped!
