Answer:
The maximum height of the ball is: 14.0625ft
Step-by-step explanation:
The missing information is:
Required
The maximum height the ball attained
First, we calculate the time to reach the maximum height.
For a function:
The maximum is:
So, the maximum of is:
Where
So:
The maximum height is then calculated as:
Answer:
-96 + 672\,i
Step-by-step explanation:
This is a product of complex numbers, so we have in mind not only the general rules for multiplying binomials, but also the properties associated with the powers of the imaginary unit "i", in particular
We start by making the first product indicated which is that of a pure imaginary number (-6i) times the complex number (8-6i). We use distributive property and obtain the new complex number that results from this product:
Now we make the second multiplication indicated (using distributive property as one does with the product of binomials), and combine like terms at the end:
I suppose you mean to have the entire numerator under the square root?
We can use a trigonometric substitution to start:
Then for ,
; for
,
. So the integral is equivalent to
We can write
so the integral becomes
