Answer:
(4x - 11i)(4x -+11i)
Step-by-step explanation:
Factor as a difference of squares
a² - b² = (a - b)(a + b)
note that i² = - 1
Given
16x² + 121
= (4x)² - (11i)²
= (4x - 11i)(4x + 11i)
Answer:
The parametric equations for the tangent line are
:
x = Cos(10) - t×Sin(10)
y = Sin(10) + t×Cos(10)
z = 20 + 2t
Step-by-step explanation:
When Z=20:
Z=2t=20 ⇒ t=10
The point of tangency is:
r(10)= Cos(10) i + Sin(10) j + 20 k
We have to find the derivative of r(t) to get the tangent line:
r'(t)= -Sin(t) i + Cos(t) j + 2 k
The direction vector at t=10 is:
r'(10)= -Sin(10) i + Cos(10) j + 2 k
So, the equation of the tangent line is given by:
x = cos 10 -t×Sin(10)
y = sin 10 + t×Cos(10)
z = 20 + 2t
Answer:

Step-by-step explanation:
What is square root of the product of the number z and itself?
Break down into smaller parts
What is the product of the number z and itself?
Product = multiply
Write an equation multiplying z by itself
z * z
Bring back the full question: What is the square root of the product of the number z and itself?
Now we can just add a
to the front of our equation to solve the problem.

Simplify
z * z = 

In this case, the square root cancels out the exponent (
), so
can simplify to z.
Hope this helps :)
Answer: Total amount the stadium would clear for all of these events combined is $1750000
Step-by-step explanation:
Since we have given that
Number of major recording acts are able to play at the stadium = 10
Average profit margin for a concert = $175000
We need to find the amount that the stadium clear for all of these events combined
As we know the formula for "Average"

Hence, total amount the stadium would clear for all of these events combined is $1750000.
Answer:
The quadratic has a minimum value.
The minimum value is at (3, 2).
Step-by-step explanation:
We are given the quadratic function:

First, since the leading coefficient is positive, this quadratic function will be concave up.
Hence, we will have a minimum value.
The minimum or maximum value is the vertex of the quadratic. The vertex is given by:

In this case, a = 3, b = -18, and c = 29. Thus, the x-coordinate of the vertex is:

And the minimum value is:
