Answer:
The vertex of this parabola is 
Step-by-step explanation:
One way of finding the x-coordinate of the vertex of a parabola is by using the equation 
From the function
, we can see that

This means that

So, the x-value of the vertex is -2. Now, we can plug this x-value into the function to find the y-coordinate of the point.

Thus, the vertex of this parabola is 
Answer:
n = 2.5 or n = (5/2)
Step-by-step explanation:
(2n+4) +6 = -9 + 4(2n+1)
first distribute the 4 to the (2n+1)
(2n+4) +6 = -9 + (8n+4)
then add 9 to both sides to cancel out the -9 on the right side
(2n+4) +15 = (8n+4)
next subtract (2n+4) from both sides to cancel out the (2n+4) on the left side combining like terms as you subtract
15 = 6n
then divide 15 by 6 to get your final answer
n = 2.5
or
n = (5/2)
Answer:
v = 1
u = 2
Step-by-step explanation:
Given is a special right triangle with angle measures as follows:
90-60-30
The side lengths would be :
2x- x
-x
in the image it shows that the second side length (the one that sees angle measure 60) is
from this we can conclude x = 1 so:
v = 1 and
u = 2
Using a Laplace expansion along the first column, we have

The determinant of a 2x2 matrix is trivial,

So we have

(23)^8 b/c when multiply powers you add the exponent values together
