Based on the calculations, the features which are features of the circle include the following:

A circle can be defined as a closed, two-dimensional curved geometric shape with no edges or corners. Also, a circle refers to the set of all points in a plane that are located at a fixed distance (radius) from a fixed point (central axis).

Mathematically, the standard form of the equation of a circle is given by;

(x - h)² + (y - k)² = r²

Where:

Given the following equation:

x² + 4x + y² - 2y - 4 = 0

x² + 4x + y² - 2y = 4

Next, we would evaluate the equation by using completing the square method:

x² + 4x + 4 + y² - 2y + 1 = 4 + 5

(x² + 2x + 2x + 4) + (y² - y - y + 1) = 9

(x + 2)² + (y - 1)² = 3²

By comparing the above equation with the standard form of the equation of a circle, we have:

Answer:

Table A

Step-by-step explanation:

Note that the curve flattens out between 4 and 6 s

So the average speed is 0( the train is standing still) in the time interval 4-6 s

From the tables we can see that (A) and (D) are the only two tables that have average speed of 0 for 4-6 second interval. So let's eliminate the other two(B and C) and focus on these two

Looking at tables A and D we can see that the average speed in the 0-2 interval is 1.0 for both

So let's focus on the only entry where the tables show different values ie the interval 2-4 = 2s)

Looking at the graph we can see that in the interval 2-4, the train travels from distance of 2m to distance of 3m. In other words it covers a distance of 1 meter ( 3 - 2 ) in 2 seconds

Therefore average speed at this time interval = 1m/2sec = 0.5 m/s

So table A shows the correct average speed

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

The written expression is given as,

0.5 is greater than the product of −2.5 and a number.

Let a number is x.

Then, The given expression is written as;

0.5 > -2.5x

Now, We can solve as;

0.5 > -2.5x

Multiply by -1 we get;

- 0.5 < 2.5x

-0.2 < x

Hence, The graph of inequality is;

⇒ Number line with Open circle on point negative 0.2 and arrow shaded to the right.

The inequality that can be used to determine x, the number of outfits Zendaya can purchase  is 329.92 + 65.65x <= 540

The given parameters are:

Budget = $540

New bicycle = $269.88.

4 bicycle reflectors = $10.57 each

Pair of a bike gloves = $17.76.

New biking outfits = $65.65 each.

Let the number of new biking outfits be x

So, we have

New bicycle + 4 * price of bicycle reflectors + Pair of a bike gloves + New biking outfits <= Budget

This gives

269.88 + 4  * 10.57+ 17.76 + 65.65x <= 540

This gives

329.92 + 65.65x <= 540

Solve the inequality

65.65x <= 210.08

Divide by 65.65

x <= 3.2

Hence, the inequality that can be used to determine x, the number of outfits Zendaya can purchase  is 329.92 + 65.65x <= 540

The point t on the unit circle is ( -1/2, √3 /2 ).

The intersection of the x-axis (the horizontal number line) and the y-axis in the cartesian system divides the coordinate plane into four equal pieces. Because each of these four areas occupies a quarter of the entire coordinate plane, they are collectively referred to as quadrants.

Consider the point t = - 4π/3 on the circle.

Now, the reference angle is π / 3.

- 4π / 3 is in quadrant 2 where the value of cosine is negative and sine is positive.

Therefore, the point t(x,y) will be:

( x, y ) = ( - cos ( π / 3 ), sin ( π / 3 ) )

The perimeter CDE of the triangle is solved to be 9.66 (to the nearest hundredth)

How to find the perimeter of CDE

Given data

C ( 4, -1 )

D ( 4, -5)

E ( 2, -3 )

perimeter of CDE = CD + CE + DE

length = √(x2 - x1)^2 + (y2 - y1)^2

using C ( 4, -1 ) and D ( 2, -3 )

CD = √(4 - 4)^2 + (-1+5)^2

CD = √(4)^2

CD = 4

using C ( 4, -1 ) and E ( 2, -3 )

CE = √(4 - 2)^2 + (-1+3)^2

CE = √(2)^2 + (2)^2

CE = √8

using D ( 4, -5) and E ( 2, -3 )

CD = √(4 - 2)^2 + (-5 + 3)^2

Let us define x to be the cost of the meal

such that we would have

x  + 22%x =  21.96

= x + 0.22x = 21.96

1.22x = 21.96

We would have to divide through the equation that we have by 1.22

x = 21.96 / 1.22

The net change between the given values of the variable is;  - 3x² - 6xh - 3h² + 23

We are given the function;

f(x) = 5 - 3x²

x = 3

x = 3 + h

The net change is just looking for the difference between f(3) and f(3 + h). Thus, we will evaluate the function at x = 3 and x = 3 + h and then calculate f(3 + h) - f(3).

f(3 + h) = 5 - 3(x + h)²

= 5 - 3x² - 6xh - 3h²

f(3) = 5 - 3(3)²

f(3) = 5 - 27

f(3) = -18
