The quadratic function f(x) has a vertex at (5,-5) and opens downward.
If g(x) = (x + 5)2 + 5, which statement is true?
A. The axis of symmetry of f(x) is x = 5, and the axis of symmetry of g(x) is x = -5.
B. The axis of symmetry of f(x) is x = -5, and the axis of symmetry of g(x) is x = -5.
C. The axis of symmetry of f(x) is x = 5, and the axis of symmetry of g(x) is x = 5.
D. The axis of symmetry of f(x) is x = -5, and the axis of symmetry of g(x) is x = 5.
Answer:
The correct answer is A.
Step-by-step explanation:
We're told that f(x) has its vertex at 5, -5 and opens downward. This tells us that it's axis of symmetry is x = 5.
The format of the function g(x) shows us that its axis of symmetry is x = -5. We're shown this because of the (x + 5)² component.
So the correct answer is A.
Using the properties of the quadratic function we can review the different answers, the correct one is
D. The axis of symmetry of f(x) is x = -5,
the axis of symmetry of g(x) is g(x) = 5.
The quadratic function is a quadratic polynomial that has a parabolic form and a general equation
g (x) = a x² + bx + c
where a, b, c are the coefficients, x is the independent variable and g the dependent
If the function has real roots it can be written in vertex form
g (x) = a (x-h) ² + k
where (h, k) are the coordinates of the vertex
The quadratic function has several properties:
The graph of this function opens up if the coefficient "a" is positive and down if it is negative, The axis of symmetry is parallel to the y axis, passing through the vertex of the function The vertex of the parabola corresponds to the maximum or minimum of the curveThe function can be written as a vertex value that cancels the binomial is where the symmetry axis passes
in this case, for the parabola to open downwards, the curve must be:
g (x) = - (x + 5) ² + 5
this is the expression in vertex form, let's find the value that cancels the binomial,
x + 5 = 0
x = -5
at this point where the axis of symmetry passes
The value of the function for this point is
x = -5
g (x0 = - (-5 + 5) ² + 5
g (x) = 5
Using the properties of the quadratic function we can review the different answers, the correct one is
D. The axis of symmetry of f(x) is x = -5, and the axis of symmetry of g(x) is
g(x) = 5

Find the length of the missing side. Simplify all radicals.
Answer:
b = 9√5 (see below)
Step-by-step explanation:
Using the Pythagorean Theorem, you can find the missing side. The two sides connect to the right angle are the legs, and the sloping side across from the right angle is the hypotenuse.
We know that:
a² + b² = c²
—where a and b are legs and c is the hypotenuse.
Plug in the known values:
a² + b² = c²
18² + b² = 27²
324 + b² = 729
b² = 405
√b² = √405
b = √81 √5
b = 9√5
Answer:
20
Step-by-step explanation:
A^2+B^2=C^2
18^2+B^2= 27^2
324+B^2= 729
-324 -324
B^2 = 405
B= [tex]\sqrt{405)\\[/tex]

A line passes through (0,4) and (3,0). Which equation does not represent the equation of this line?
a
y - 0 = - 4/3 (x - 3)
b
y = - 4/3x + 3
c
y - 4 = - 4/3 (x - o)
d
x/3 + y/4 = 1
e
4x + 3y = 12
Answer:
A
Step-by-step explanation:
use both points to find the slope using the equation
y2-y1/x2-x1, so , -2-4/2-0 = -6/2 = -3. slope or m = -3
then the y int can be any y point, so either -2 or 4. in this case they used 4.

In triangle GHJ, mH = 85° and mG = 60°.
Choose the correct symbol to put in the blank.
HJ ___ JG

Answer: The correct symbol is '<'.
Step-by-step explanation:
Given: In triangle GHJ
[tex]m\angle H=85^{\circ}[/tex] and [tex]m\angle G=60^{\circ}[/tex]
Here angle H is opposite to side JG and angle G is opposite to side HJ
We know that,
The side opposite to the greater angle of a triangle is greater.
Since [tex]m\angle H> m\angle G[/tex]
Then, JG > HJ
Hence, HJ < JG

earth's equator has a diamter of 7926.4 miles. which equation can be used to find the circumference of earth at the equator?
Answer:
To find the circumference you need to use C= 2πr but since you started with the diameter you need to divide it by 2 and you will get 3963.2. After you get the radius use the formula C= 2πr and you will get 24901.52
The equation would be written as 2 x π x 3963.2 = 24901.52

- 1x + 15 = 9
Explanation:
The term "rising" will indicate that we should use positive 1/3 instead of negative 1/3.
Choices A and C use "decreasing" which is why they involve -1/3. This is why we can rule out these two choices.
