<span>x^2 + y^2 – x – 2y – 11/4 = 0
x^2 - x + y^2 - 2y = 11/4
Using completing the square method:
x^2 - x + 1/4 + y^2 - 2y + 1 = 11/4 + 1 + 1/4
(x - 1/2)^2 + (y - 1)^2 = 4
coordinates: (1/2 , 1)
radius: sqrt (4)</span>
Could you please provide the equation and the rest of the question?
Answer: he drove 18.25 miles per gallon
Step-by-step explanation:
365/20=x/1
20x=365
x=18.25
The ball takes 1.5 seconds to reach its maximum height
The ball's maximum height is 44 feet
<em><u>Solution:</u></em>
Given that,
<em><u>The height in feet after t seconds is given by the function:</u></em>
Let us first find the derivative of h(t)
Differentiate the given function with respect to t
At the maximum height the derivative of the function needs to be 0
Thus the ball takes 1.5 seconds to reach its maximum height
<h3><u>Find the ball's maximum height:</u></h3>
Substitute t = 1.5 in given function
Thus ball's maximum height is 44 feet
Answer:
125i.
Step-by-step explanation:
5^3 is 125 i^2 is -1 so i^8 is positive and you have 1 i left.
