Step-by-step explanation:

we have been given an expression [tex]\frac{\frac{2}{3}}{-4}-\left(\frac{1}{6}-\frac{8}{6}\right)[/tex]. We are asked to simplify our given expression.

Using quotient rule [tex]\frac{\frac{a}{b}}{c}=\frac{a}{bc}[/tex], we will get:

[tex]\frac{2}{3\cdot -4}-\left(\frac{1}{6}-\frac{8}{6}\right)[/tex]

Now, we will combine like terms:

[tex]\frac{2}{-12}-\left(\frac{1-8}{6}\right)[/tex]

[tex]\frac{2}{-12}-\left(\frac{-7}{6}\right)[/tex]

[tex]-\frac{2}{12}+\frac{7}{6}[/tex]

[tex]-\frac{1}{6}+\frac{7}{6}[/tex]

Let us combine like terms:

[tex]\frac{-1+7}{6}[/tex]

Answer:

kilgore, 140 miles

Step-by-step explanation:

Kilgore drives farther than Julio with a difference of 27.5 miles. Julio drives 112.5 miles while Kilgore drives 140 miles.

To determine who drives farther, we need to calculate the distance driven by Julio and Kilgore.

Kilgore drives farther. The difference in the distance is 140 miles - 112.5 miles = 27.5 miles.

The required time that it takes for 90 miles is 1.5 hour.

The average speed is calculated for a period of time while instantaneous speed is calculated at certain instant of time. For instantaneous speed and average speed are equal for an object moving with constant speed.

The total distance is given as 240 miles.

And, the time taken is 4 hours.

Now, the speed can be calculated by taking the ratio of the distance and time as below,

Speed = Distance ÷ Time

⇒ Speed = 240 ÷ 4 = 60

Thus, the time taken to drive 90 miles is calculated as,

Time = Distance ÷ Speed

⇒ Time = 90 ÷ 60 = 1.5

Hence, the time taken to cover 90 miles is 1 hour.

Answer:

A. y-axis only

Step-by-step explanation:

We have the graph of  as given below.

It can be seen that  passes through the points (0,0), (4,0) and (6,0).

Also, the graph is plotted in the 1st and 2nd quadrant symmetrically along the y-axis.

Hence, the axis of symmetry of  is the y-axis only.

The graph of r = 1/ (1 - 5sinθ) is symmetric about the y-axis only.

It expresses x and y in terms of r and θ:

x = r cos(θ) , y = r sin(θ)

In polar coordinates, the x-axis corresponds to θ = π/2 and the y-axis corresponds to θ = 0 (or θ = π). So to test for symmetry, we need to check whether replacing θ with π - θ (which reflects the graph across the y-axis) or replacing r with -r (which reflects the graph across the origin) gives us the same equation.

If we replace θ with π - θ, we get:

r = 1 / (1 - 5sin(π - θ)) = 1 / (1 + 5sinθ)

This equation is not the same as the original equation, so there is no symmetry about the y-axis.

If we replace r with -r, we get:

-r = 1 / (1 - 5sinθ)

Multiplying both sides by -1, we get:

r = -1 / (1 - 5sinθ)

This equation is also not the same as the original equation, so there is no symmetry about the origin.

However, if we replace θ with π/2 - θ, we get:

r = 1 / (1 - 5sin(π/2 - θ)) = 1 / (1 + 5cosθ)

This equation is the same as the original equation, so the graph is symmetric about the y-axis.

Therefore, the graph of r = 1/ (1 - 5sinθ) is symmetric about the y-axis only.
