Answer:
At 1.5 seconds and 2.5 seconds
Step-by-step explanation:
Because this is parabolic motion, the object will reach the height of 68 feet when it's going up AND when it's coming down. In order to find out those times, you set the h on the left side of the equation equal to 68, because h stands for height.
Set that equal to 0 and factor to solve for t:
Using the quadratic formula, we get t = 1.5 and t = 2.5
Each bag of popcorn was $3.33 dollars because you divide 40 dollars by 12 bags. That is how you get your answer.
When comparing x^2 + 10 and x + x + x equals to:
x^2 +10 is greater than x + x + x when x = -5
Because -5^2 + 10 = 25 + 10 = 35
and -5 + -5 + -5 = -15
So, 35 > -15
Answer:
<h3>12.56</h3>
Step-by-step explanation:
To get the length of the arc, we are going to use the formula for calculating the circumference of a semicircle.
Circumference of a semi circle = πd/2
Given
Diameter d = 8
π = 3.14
Substitute;
C = 3.14(8)/2
C = 3.14 * 4
C = 12.56
Hence the the length of the arc is 12.56
