Answer:
16.7
Step-by-step explanation:
Following SOHCAHTOA, we see that Sine = Opposite/Hypotenuse is appropriate for this question. Since the sine of 33 is approximately 0.54, we see that the Opposite(9) / Hypotenuse(x) should be 0.54.
9 / x = 0.54
9 = 0.54x
9/0.54 = x
16.7 = x

What is a straight line?
A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined both sides of a point and has no curve.

Equation of parallel line:
Answers
1)Parallel means they have to have the same slope. Since our equation is y=2/3x+1, a line parallel to that would be(using out points) -5=2/3(-4)+b.
To find the y-intercept, solve for "b".
b=-7/3
Our equation would then be y=2/3x-7/3
2)Perpendicular lines have opposite-reciprocal slopes. our previous equation was y=2/3x+1, so our new equation would be -5=-3/2(-4)+b. Now lets solve for b.
b=-11
So our perpendicular equation would be y=-3/2x-11

To calculate the greatest common factor (GCF) of 28 and 42, we need to factor each number (factors of 28 = 1, 2, 4, 7, 14, 28; factors of 42 = 1, 2, 3, 6, 7, 14, 21, 42) and choose the greatest factor that exactly divides both 28 and 42, i.e., 14.

Answer:
g(x) = x² - 5
Step-by-step explanation:
The vertex form of a parabola is:
→ y = (x - a)² + b
where (a, b) is the vertex of the parabola.
From the graph, we can identify that the vertex has been shifted down 5 units, and it has not been shifted horizontally. Therefore, we can assign the following a and b values:
- a = 0
- b = -5
Now, we can plug these into the vertexformequation to get the equation of the function g(x):
y = (x - 0)² + (-5)
This simplifies to:
y = x² - 5
