In order to complete the function table, we just need to locate the input values in the x-axis and then find the corresponding values of y in the line.
For x = -7, we have y = 9
For x = 1, we have y = -3
For x = 5, we have y = -9
So the output values for the table are

We have to find x.
We can use the trigonometric relations to find the value of x.
We know that, for a right triangle, the sine of an angle is equal to the quotient between the opposite side and the hypotenuse.
In this case, the opposite side of the angle is the height of the plane (4 mi) and the hypotenuse is x, so we can write:
[tex]\begin{gathered} \cos (40\degree)=\frac{\text{Opposite}}{\text{Hypotenuse}}=\frac{4}{x} \\ x=\frac{4}{\cos (40\degree)}\approx\frac{4}{0.766}\approx5.22 \end{gathered}[/tex]Answer: the value of x is approximately 5.22 miles.

To know how many hours you will have to work, we need to use the given rate of $4.50 per hour as follows:
[tex]\text{ \$1000}\times\frac{1\text{ hour}}{\text{ \$4.50}}=\frac{1000\times1}{4.5}=\frac{1000}{4.5}=222.22\text{ hours}[/tex]Because 1 hour is equivalent to $4.50.

From the given, it shows two points that pass through the given graph. These points are:
Point A : x1, y1 = 4, 1

What is the solution to the equation k - 4 3/4 = 8 1/4?k = 4 1\2k = 12k = 13k = 4
Answers
Answer:
Explanation:
The given equation is
k - 4 3/4 = 8 1/4
The fist step is to convert the mixed number to improper fractions.
4 3/4 = 19/4
8 1/4 = 33/4
Thus, the expression becomes
k - 19/4 = 33/4
Adding 19/4 to both sides, we have
k - 19/4 + 19/4= 33/4 + 19/4
k = 52/4
k = 13

I need help with this practice problem solving It is trigonometry At the bottom of the picture is the answer options, one answer per box.
Answers
First, remember how does the graph of the function f(x) = tan(x) look:
For the inverse of a function to exist, the function has to be an injective function.
A function is injective if it passes the horizontal line test.
Since the function f(x) = tan(x) is periodic and its period is equal to π, its domain must be restricted to an interval of length π in order to pass the horizontal line test.
If we keep the piece of the graph that passes through the origin, we must restrict the domain of the tangent function to the interval (-π/2,π/2) for the function to be injective, and thus for the inverse of the function to be defined.
Therefore, in both cases the answer is:
