Graph the function identify the vertex and axis of symmetry f(x)=x^2+4x-2
A. axis of symmetry:x=2
(2,6)
B. axis of symmetry: x= -2
(-2,6)
C. axis of symmetry: x= 2
(2,-6)
D. axis of symmetry: x=-2
Vertex: (-2,-6)
The vertex and the axis of symmetry are (-2, -6) and x = -2, respectively
How to determine the vertex and the axis of symmetry?The equation of the function is given as
f(x) = x^2 + 4x - 2
The above equation is a quadratic equation
Next, we plot the equation on a graph (see attachment)
The vertex of the graph is the minimum or the maximum of the graph
In this case, we have
Minimum= (-2, -6)
This means that
Vertex = (-2, -6)
The axis of symmetry is the x-coordinates of the vertex
So, we have
x = -2
Hence, the vertex is (-2, -6) and the axis of symmetry is x = -2

Area of a triangle with a vertical height of 1/2 m and base of 1/4 m.
Answer:
1/16 squared meters
Step-by-step explanation:
The formula to find the area of a triangle is [tex]\frac{Base * Height}{2}[/tex]
We can form an equation if we substitute the values (base and height).
[tex]\frac{1/2*1/4}{2}[/tex]
1/2 * 1/4 = 1/8
and [tex]\frac{1/8}{2}[/tex] = 1/16
Therefore, the area of a triangle with a vertical height of 1/2 m and a base of 1/4 m is 1/16 meters squared.

Work out the area of the triangle. Round
your answer to 1 DP.
The area of the triangle for the given parameter is 12.4 squared cm.
How to calculate the area of the triangle?
In mathematics, the area of the triangle is classified into three forms isosceles, scalene and equilateral. Depending upon the sides of the triangle, it is classified. That means, when the two sides are equal then the triangle is isosceles triangle.
According to the question, the given parameters for the calculation of the area of the triangle is as written below:
Side of the triangle(a) = 5.2 cm. Angle of a triangle(B) = 67°.
Using standard formula for the area of the triangle, we get:
Area of the triangle = (1/2)(5.2)(5.2)sin(67°) = 12.4384 = 12.4 squared cm.
Hence, the area of the triangle for the given parameter is 12.4 squared cm.

f(x) = 3 x + 1 and g (x) = 2x - 3. find g (f(x))
Answer:
6x -- 1
Step-by-step explanation:
To Solve for g(f(x)), bear in mind
f(x) = 3x + 1
g(x) = 2x -- 3
g(f(x)) = 2x -- 3. (Calm down right?)
Let x = f(x).
if you recheck g(x) = 2x -- 3 so we got the (x) from it (do you get?)
g(f(x)) = 2(3x + 1) -- 3
g(f(x)) = 6x + 2 -- 3
g(f(x)) = 6x -- 1
#AllonGod
Answer:
Step-by-step explanation:
To find g(f(x)), first, understand that this means we are going to use the function of f(x) where the x would be in g(x).
1. First, identify the x in g(x) and replace it with the function of f(x)
g(x)=2x-3; so g(f(x))= 2(3x+1) -3
2. Simplify the equation by distributing the 2 and combining like terms.
2*3x=6x and 2*1=2, so we are left with 6x+2-3. After, just do 2-3 to end up with
g(f(x))=6x-1

By using internal angles of the triangles and the definition of supplementary angles, the measure of the angle MNP is equal to 54°.
How to determine a missing angle in a geometric systemHerein we find a geometric system formed by two common semirrays with a common vertex at point N and a line segment MP such that triangle MPN is a right triangle. By Euclidean geometry we know that the sum of the measures in the internal angles equals 180°:
m ∠ NMP + m ∠ MNP + m ∠ MPN = 180° (1)
And the two angles at point P are supplementary angles:
24 · x + m ∠ MPN = 180° (2)
Then, by (1):
90° + 9 · x + m ∠ MPN = 180°
m ∠ MPN = 90° - 9 · x
By (1) in (2):
24 · x + 90° - 9 · x = 180°
15 · x = 90°
x = 6
Then, the measure of the angle MPN is equal to:
m ∠ MNP = 9 · x
m ∠ MNP = 9 · 6
m ∠ MNP = 54°

Dimension of the rectangle;
Width(w)
Length,L= 10 + w
volume of the box = length * width * height
Dimension of the box;

The volume of the box is 672 in³;
⇒V=lwh
⇒V=2 (x -4)( x + 6)
⇒672 in³ = 2x² + 4x - 48
⇒2x² + 4x - 720 = 0
⇒x^2 + 2x - 360 = 0
⇒(x +20)(x - 18) = 0
⇒x = 18
⇒x=-20 (value of the dimension will not be negative.

Answer:
x=16
Step-by-step explanation:
I apologize I have not done geo in a while so I am not sure what the theorem is, but there is a theorem that states that when a transversal intersects with two parallel lines, two angles that are facing the same direction are the same angle. (the two white angles that i have marked are equal)
next, two lines that intersect each other will have the same angle measurements on opposite sides (the green marked angles are equal)
so that means 3x - 8 = x + 24
