a highway has an optional toll lane that drivers may take to reduce the time they spend driving. drivers pay a small fee to enter the toll lane ($0.25) . then, once they leave the toll lane, they pay a fee based on the number of miles they have traveled on the toll lane. assume that the driver may leave the lane after any whole number of miles and pays for exactly that number, without rounding up. note that there is a linear relationship between the number of miles a vehicle has traveled and the price of the toll. a. if frank is on the toll road for 4.00 miles and then leaves the lane, how much will he have to pay total for the trip?

Answers

He have to pay $3.25.

Let the number of miles traveled by a driver be x

The toll paid by the driver is then represented as y. (in dollar)

Linear equation : an equation in which there is only one variable present. It is of the form Ax + B = 0, where A and B are any two real numbers and x is an unknown variable that has only one solution.

Since there is a linear relation between the two, we can assume the equation can be written as:

y = mx + c

From the given data, we get

0.24 = m(0) + c

c = 0.25

Using the second point:

1 = m(1) + 0.25

m = 1 − 0.25 = 0.75

Hence, the equation is y = 0.75x + 0.25.

If  x = 4, then:

y = 0.75 × 4 + 0.25

y = 5.50

Hence, He have to pay $3.25.

The value of csc x=-13/5.

Given that the sin x=-5/13 and x∈[3π/2 , 2π).

A trigonometric function is a real function that relates the angle of a right triangle to the ratio of the lengths of the two sides. The basic functions are sin, cos, tan, cot, sec, csc.

The given function is sin x=-5/13.

As we all know that sin x=1/csc x or csc x=1/sin x.

As it is given that x∈[3π/2 , 2π) that means x lies in fourth quadrant and in fourth quadrant sin and csc is negative in it.

So, we will apply this identity csc x=1/sin x, we get

csc x=1/(-5/13)

csc x=-13/5

And it also lies in x∈[3π/2 , 2π).

Hence, the value of csc x when sin x=-5/13 and x∈[3π/2 , 2π) is csc x=-13/5.

The value of x that makes the lines m and n to be parallel lines is 45 degrees

How to determine the value of x that makes the line parallel?

The figure that completes the question is added as an attachment

From the figure, we have the following angles

Angle = x and 3x

The angles are interior of parallel lines

This means that they add up to 180 degrees

So, we have the following equation

Angle 1 + Angle 2 = 180 degrees

Substitute the known values in the above equation

So, we have

x + 3x = 180

Evaluate the like terms in the above equation

So, we have:

4x = 180

Divide both sides of the above equation by 4

So, we have

x = 45

Hence, the value of x that makes the lines m and n to be parallel lines is 45 degrees

The solution of the simultaneous equations are x = 2, 3 and y = 3,9.

What are simultaneous equation?

In mathematics; a set of simultaneous equations, also known as a system of equations or an equation system, it is a finite set of equations for which common solutions are sought.

WE have given simultaneous equations as;

y = x^2    ...(i)

y = x + 6  .....(ii)

Now Equating (i) and (ii) we get,

x^2 = x + 6

or, x^2 - x - 6 = 0

Then Solving we get;

x^2 - 3x - 2x - 6 = 0

x(x - 3) -2(x - 3) = 0

(x - 2)(x - 3) = 0

So, x = 2, 3

Now Putting x = 2, 3 in equation (i) we get;

y = 2^2

y = 4

and,

y = 3^2

y = 9

Thus, y = 3,9

Hence the solution of the simultaneous equations are x = 2, 3 and y = 3,9.

Yes, it is true that if "x" is an optimal solution to a linear programming problem, then it is a vertex of the feasible region.

Linear programming (LP) is one of the most basic methods of optimization. By making a few simplifying assumptions, it can assist you in solving some highly complicated optimization issues.Linear programming is a basic approach that uses linear functions to represent complicated connections and then finds the optimum spots.Linear programming is used to find the best solution to a problem given certain limitations. In linear programming, we transform a real-world issue into a mathematical model. It consists of an objective function, linear inequalities, and constraints.A graphical technique entails constructing a collection of linear inequalities that are constrained. The disparities are then plotted on an X-Y plane. When we plot all of the inequalities on a graph, the intersecting region provides us with a viable region. The viable region describes all of the values that our model may take. It also provides us with the best solution.At the point of intersection, when the constraints are active, the best viable solution is found. This signifies that the intersection of the equations provides the best answer.

d= 4 (13)^(1/2)

A prime meridian refers to an arbitrary meridian which is there in a geographic coordinate system. Here, the longitude is defined as 0°.

A prime meridian and its anti-meridian will together form a great circle in a geographic coordinate system.

The Equator is a circle of latitude, about 40,075 km in circumference, that divides Earth into the Northern and Southern hemispheres.

It is an imaginary line that is located at 0 degrees latitude, and is a halfway between the North and South poles.
