Answer:

Part 1) The vertex is the point (-2,-4)

Part 2) The axis of symmetry is equal to x=-2

Step-by-step explanation:

we know that

The equation of a vertical parabola into vertex form is equal to

y=a(x-h)^{2}+k

where

(h,k) is the vertex of the parabola

The axis of symmetry of a vertical parabola is equal to

x=h ----> the x-coordinate of the vertex

In this problem we have

y=2(x+2)^{2}-4

The vertex is the point (-2,-4)

The axis of symmetry is equal to the coordinate of the vertex

so

x=-2

see the attached figure to better understand the problem

A = m - n solve for n <br><br> a) n= a plus m<br> b) n= m-a<br> c) n=a-m<br> d) n= -m - a
mariarad [96]
B) n=m-a
Add n to both sides, leaving a+n on the left=m on the right
Subtract a from both sides to get n=m-a

Tan is equal to sin over cosine so if this is all the info you are given sin.is 3 and cosine is 4. However it is possible term cancel out like sin could be 3/5 and cosine 4/5 which would still give tan 3/4. Actually that is probably what it is to make a 3 4 5 triangle.
To make sine and cos equal the opposite and adjacent sides must be equal. By corresponding angles it is isosceles so b and c must be 45
