Answer: The projectile reaches its maximum height after 20 seconds.
Step-by-step explanation:
Given the function:
You can following formula (which gives the x -coordinate of the vertex of the parabola) in order to find after how many seconds the projectile takes to reach its maximum height:
In this case you can identify that the values of "a" and "b" are:
Then, substituting values into the formula, you get the following result:
Therefore,based on this, the conclusion is: The projectile reaches its maximum height after 20 seconds.
R = 12 inches, the radius of the wheel.
The circumference of the wheel is
2πr = 2π(12) = 24π inches.
WHen the wheel makes 15 revolutions, the car will travel 15 times the circumference, which is
15*(24π) = 360π inches = 1131 inches.
Answer: 1131 inches
Answer: $9.87
Step-by-step explanation: To find the average add both 15.84 + 3.9 and you get 19.74
Divide 19.74 by 2 you get $9.87

The angles that share the same tangent value as of tan 45 degrees would be in Quadrant III. This is because in this quadrant the ratios would equal a positive value, which is the same as in the first quadrant, also positive. Tan 45 = 1.
We would need both the x and the y values be either both positive or negative to get a positive final value.
