f(x) = x² + 6x-2
g(x) = x - 6
The composite function of f(x) and g(x) is given as follows:
f(g(x)) = x² - 6x - 2.
What is the composite function of f(x) and g(x)?The composite function of f(x) and g(x) is given by the following rule:
(f ∘ g)(x) = f(g(x)).
It means that the output of the inside function serves as the input for the outside function.
The functions for this problem are given as follows:
f(x) = x² + 6x - 2.g(x) = x - 6.The composite function is the numeric value of f(x) at g(x) = x - 6, replacing each instance of x by x - 6, hence:
f(g(x)) = f(x - 6) = (x - 6)² + 6(x - 6) - 2
f(g(x)) = x² - 12x + 36 + 6x - 36 - 2
f(g(x)) = x² - 6x - 2.

You sailed 0.055 units to the left and found treasure at 0.085 units find where the ship started
The ship started at the Position 0.14 units.
To determine the starting position of the ship, we can consider the distance sailed to the left and the distance to the treasure.
Given that you sailed 0.055 units to the left and found the treasure at 0.085 units, we can represent this situation mathematically as follows:
Starting position + Distance sailed to the left = Distance to the treasure
Let's assign a variable, "x," to represent the starting position of the ship.
The equation becomes:
x - 0.055 = 0.085
To find the value of x, we can solve this equation by isolating x on one side:
x = 0.085 + 0.055
x = 0.14
Therefore, the ship started at the position 0.14 units.

can you please help me solve this logarithm function
Answer:
I think the solution is x=84 if this is correct can u mark me brainliest
Answer:
\(\boxed{\sf{x=84}}\)Step-by-step explanation:
This problem can be solved by using the logarithm function.
Isolate the term of x from one side of the equation.
First, you divide by -6 from both sides.
\(\Longrightarrow: \sf{\dfrac{-6\log _3(x-3)}{-6}=\dfrac{-24}{-6}}\)
Solve.
Divide the numbers from left to right.
-24/-6=4
Rewrite the problem down.
\(\Longrightarrow: \sf{\log _3(x-3)=4}\)
x-3=81
Add by 3 from both sides.
\(\Longrightarrow:\sf{x-3+3=81+3}\)
Solve.
Add the numbers from left to right.
81+3=84
\(\Longrightarrow: \boxed{\sf{x=84}}\)
Therefore, the solution is x=84, which is our answer.I hope this helps you! Let me know if my answer is wrong or not.
Determine the vertical asymptote and horizontal asymptote
The value of vertical asymptotes is, x = 9
And, The value of Horizontal asymptotes is,
y = - 4
We have to given that;
Expression is,
⇒ j (x) = 1/(x - 9) - 4
Now, We can simplify as,
⇒ j (x) = 1/(x - 9) - 4
⇒ j (x) = (1 - 4(x - 9)] / (x - 9)
⇒ j (x) = [1 - 4x + 36] / (x - 9)
⇒ j (x) = (- 4x + 37) / (x - 9)
Hence, For vertical asymptotes make denominator zero.
As, x - 9 = 0
x = 9

50 Points!!!!!! Triangle ABC is given.
Angle A is labeled two x degrees. Angle B is labeled forty degrees. Angle C is labeled three x degrees.
What is the measure, in degrees, of ∠A?
Enter your answer in the box.
All 3 angles add up to 180 degrees.
so 40 + 2x + 3x = 180
40 + 5x = 180
5x = 140
x = 28
So angle A = 2x = 2(28) = 56 degrees.
Answer: 56°
Step-by-step explanation:
We know that a triangle's angles add up to 180 degrees. We will create an equation to help us solve for x using this information.
Given:
2x + 3x + 40 = 180
Combine like terms:
5x + 40 = 180
Subtract 40 from both sides of the equation:
5x = 140
Divide both sides of the equation by 5:
x = 28
Next, we will substitute this value of x into the expression for ∠A.
∠A = 2x = 2(28) = 56°

To reflect a point over the y-axis, we negate the x-coordinate of the point. To reflect the resulting point over the x-axis, we negate the y-coordinate of the point. So, to find the new point A'', we can perform these operations on the original point A:
1. Reflect A over the y-axis to get A': (-2, 2)
2. Reflect A' over the x-axis to get A'': (-2, -2)

Right triangle with a hypotenuse of 159 ft and Angle A = 34 degree
Calculate the length of the sides they should be rounded to the nearest whole foot. The rounded for the legs (side) should be used to calculate the area of the triangle
the length of side a is 91 ft (rounded to the nearest whole foot) and the length of side b is 132 ft (rounded to the nearest whole foot). The area of the triangle is approximately 6007 sq ft.
Given: The hypotenuse of the right triangle,
c = 159 ft; angle A = 34°
We know that, in a right-angled triangle:
\($$\sin\theta=\frac{\text{opposite}}\)
\({\text{hypotenuse}}$$$$\cos\theta=\frac{\text{adjacent}}\)
\({\text{hypotenuse}}$$\)
We know the value of the hypotenuse and angle A. Using trigonometric ratios, we can find the length of sides in the right triangle.We will use the following formulas:
\($$\sin\theta=\frac{\text{opposite}}\)
\({\text{hypotenuse}}$$$$\cos\theta=\frac{\text{adjacent}}\)
\({\text{hypotenuse}}$$$$\tan\theta=\frac{\text{opposite}}\)
\({\text{adjacent}}$$\) Length of side a is:
\($$\begin{aligned} \sin A &=\frac{a}{c}\\ a &=c \sin A\\ &= 159\sin 34°\\ &= 91.4 \text{ ft} \end{aligned}$$Length of side b is:$$\begin{aligned} \cos A &=\frac{b}{c}\\ b &=c \cos A\\ &= 159\cos 34°\\ &= 131.5 \text{ ft} \end{aligned}$$\)
Now, we have the values of all sides of the right triangle. We can calculate the area of the triangle by using the formula for the area of a right triangle:
\($$\text{Area} = \frac{1}{2}ab$$\)
Putting the values of a and b:
\($$\begin{aligned} \text{Area} &=\frac{1}{2}ab\\ &=\frac{1}{2}(91.4)(131.5)\\ &= 6006.55 \approx 6007 \text{ sq ft}\end{aligned}$$\)
Therefore, the length of side a is 91 ft (rounded to the nearest whole foot) and the length of side b is 132 ft (rounded to the nearest whole foot). The area of the triangle is approximately 6007 sq ft.

Los puntos A(13, a) y B (4,b) pertenecen a una parábola de vértice V (h, 1) Además el eje focal es paralelo al eje de las abscisas ,su parámetro es p y A, B están
contenidos en la recta 2x - y - 13 = 0. Hallar a" + bP.
The points on a parabola with the focal axis parallel to the abscissa axis, of parameter p and A, B is -12.
How to calculate parameters?Since A and B are points on the parabola, write two equations using the general form of the parabolic equation:
(x - h)² = 4p(y - 1)
The focal axis is parallel to the x-axis, so the distance from the vertex to the focus is equal to p. Therefore, use the distance formula to write an equation for the distance between the vertex and point A:
√((13 - h)² + (a - 1)²) = p
Similarly, write an equation for the distance between the vertex and point B:
√((4 - h)² + (b - 1)²) = p
A and B lie on the line 2x - y - 13 = 0, so substitute the x and y coordinates of A and B into this equation and solve for a and b:
2(13) - a - 13 = 0
2(4) - b - 13 = 0
Solving these equations gives us a = 3 and b = -5.
Now three equations and three unknowns (a, b, and h):
√((13 - h)² + 4) = p + 1
√((4 - h)² + 36) = p + 1
2h - 3 - 13 = 0
The third equation simplifies to 2h = 16, or h = 8.
Substituting this value of h into the first two equations and squaring both sides:
(13 - 8)² + 4 = (p + 1)²
(4 - 8)² + 36 = (p + 1)²
Simplifying these equations and solving for p gives us p = 3.
Finally, find a" + bP by substituting the values found for a, b, and p:
a" + bP = 3 + (-5)(3) = -12
Therefore, the solution is a" + bP = -12.

Explanation:
Let's start with the exterior angle 116 degrees.
The interior angle adjacent to this will add to 116 and we'll get 180
(interior angle) + (exterior angle) = 180
(angle VWX) + (angle VWY) = 180
(angle VWX) + (116) = 180
angle VWX = 180 - 116
angle VWX = 64
-----------------
Let's focus solely on the interior angles of triangle VWX
We found angle W to be 64. Angle X is given to be 44. Angle V is unknown, but we can solve for it like such
V+W+X = 180
V+64+44 = 180
V+108 = 180
V = 180-108
V = 72
--------------
The three interior angles of triangle VWX are:
V = 72
W = 64
X = 44
This will determine the order of the side lengths from smallest to largest. Recall that the smallest side of a triangle is always opposite the smallest angle. Similarly, the largest side is always opposite the largest angle.
Based on those V,W,X angle values, we know that
WX = longest side (since the angle opposite V = 72 is largest)
VW = shortest side (since X = 44 is the smallest angle and it is opposite VW)
The order of the sides is therefore:
VW < VX < WX
We don't involve point Y because it's not part of the triangle.
