Step-by-step explanation:

Answer:

Step-by-step explanation:

y = -5 (x² + 1 - 2x) + 5

y = -5x² + 10x - 5 + 5

y = -5x² + 10x

maximum height = y coordinate of the vertex of the parabola

x = -10/-10

x = 1

y = -5 (1)² + 10 (1)

y = -5 + 10

y = 5

5 meters

b) the x coordinate of the vertex is 1

1 meter

c) since the term without x is 0, the ball was kicked from the ground

0 meters

d) we have to find the x-intercept

-5x² + 10x = 0

-5/-5 x² + 10/-5 x = 0/-5

x² - 2x = 0

x(x-2) = 0

x = 0

x = 2

The data is A. periodic with period of 3 and amplitude of about 7.5

From the information, we are given the number of hours as well as the number of bikes. It should be noted that we can see that ty values are periodic as it repeats every third value.

Also, the amplitude will be the:

= Larger value - Smallest value / 3

For the first set it is 7.

For the second set it is 7.5

For the third set it is 8

For the fourth set it is:

The coordinates of the recycle bin will be = ( -1, 2.5 )

According to the information given in the question,

The coordinates of the vertices of the park are,

( 1, 1 ), ( 1, 4 ), and ( -3, 4 )

We have to find the coordinates of the recycle bin.

Let us consider the equation of the circle,

[tex]x^{2} +y^{2}+Dx + Ey+ F =0[/tex]

So putting the values of the coordinates into the equation,

First Equation,

[tex]1^{2}+1^{2} + D + E + F = 0[/tex]

Second Equation,

[tex]1^{2} +4^{2} +D + 4E + F=0[/tex]

Third Equation,

[tex](-3)^{2} + 4^{2} - 3D+4E+F=0[/tex]

Subtracting the first equation from the second,

[tex]1^{2} +4^{2} +D + 4E -E=0[/tex]

15 + 3E = 0

3E = -15

E = -5

Subtracting the third equation from the second,

1 + 16 - 9 - 16 + D + 3D = 0

4D = 8

D = 2

Putting the values of E and D in the first equation,

1 + 1 + D + E + F = 0

F = -2 - D - E

F = 1

So now the equation of the circle becomes,

[tex]x^{2} +y^{2}+2x - 5y+ 1 =0[/tex]

By expanding the above equation we can find the standard equation,

[tex]x+2x+1^{2} +y^{2} -5y+ 2.5^{2}- 1^{2} -2.5^{2} +1 =0[/tex]

[tex](x+1)^{2} + (y - 2.5)^{2} = 1^{2} + 2.5^{2} -1[/tex]

[tex](x+1)^{2} + (y - 2.5)^{2} = 2.5^{2}[/tex]

So the required circumcenter will be = ( -1, 2.5 )

Therefore, the coordinates of the recycle bin will be = ( -1, 2.5 )

The distance between the library and the school using the coordinates plane is 7.28 miles.

A coordinate plane is a two-dimensional plane which is formed by the intersection of two number lines - a horizontal number line called the x-axis and is a vertical number line called the y-axis. It is a graphing and description system for points and lines. On the provided coordinate plane, the coordinate of the library is (-3,3) and the coordinate of the school is (4, 1).

The distance formula between two coordinates is given by:

d =√((x2 – x1)^2 + (y2 - y1)^2)

Using the distance formula, the distance between the library and the school are:

d =√((-3 – 4)^2 + (3 - 1)^2)

The term that represents the situation shown in the graphic below is B. a reflection

A glide reflection or transflection is a symmetry operation in two-dimensional geometry that combines a reflection over a line with a translation along that line into a single operation.

An exchange of points from one side of a line with points on the other side of the mirror at the same distance from the mirror occurs when a mirror line is fixed in the plane. There is a mirror line in every reflection. A mirror reflection is followed by a translation that is parallel to the mirror to create a glide reflection.

Here, the shape is mirrored in the reflection. A line, called the line of reflection, will allow an image to reflect through it. Every point in a figure is said to reflect the other figure when they are all equally spaced apart from one another.

In conclusion, based on the information given, it should be noted that the correct option is B.

Answer:

The number of downloads of the standard version is 230.

Step-by-step explanation:

Let x be the number of downloads of the standard version.

The number of downloads of the high-quality version is 4x.

The total size downloaded for the standard version is 2.8x MB.

The total size downloaded for the high-quality version is 4.3(4x) = 17.2x MB.

The total size downloaded for both versions is 2.8x + 17.2x = 4600 MB.

Combining like terms, we have 20x = 4600 MB.

Dividing both sides by 20, we have x = 230 downloads of the standard version

Answer: Y=-2x-5

Step-by-step explanation:

Points: (-4, 3) & (-3, 1)

To find the slope, we use m= (y₂-y₁)/(x₂-x₁)

With these points, m= (1-3)/(-3--4)

This gives us m= -2/1, or -2

Slope-intercept form is y=mx+b

We can plug in the slope now, so y=-2x+b

B is the y-intercept, which is -5, in this case

This gives us y=-2x-5

The function is actually (0,-3)(2,4)

Slope:

slope = y2-y1  = 4-(-3) = 7/2

            x2-x1      2-0

y intercept: (0,-3)

The largest number is 20 .

What is largest ?

There is a big number—a googolplex—that exists. It consists of 1 and 10100 zeros (googol). A googolduplex, which is an even larger number, is also present. It is 1 and over a googol zeros after that.

Let 'n' be any number, odd or even.

2n will always be even number. This is because, 2n has 2 as common factor. So, 2n is always even.

Eg: 2= 2×1, n=1 ; 4=2×2, n=2 etc

Numbers are even, consecutive.

Consecutive even numbers are 2n-2, 2n, 2n+2,

Eg : For consecutive even numbers, put n=2

2n-2=4-2=2

2n=4

2n+2 =4+2=6,

we get 2,4,6 which are consecutive even nos.

So, numbers are 2n-2, 2n and 2n+2

Their sum= 2n+2+2n+2n-2=6n

Sum=54

6n=54

n=54/6=9

So, n=9

Consecutive numbers are

2n-2= (2×9)-2=16

2n=2×9=18

2n+2=18+2=20.

So, numbers are 16, 18, 20. Their sum is 54.

The area of the square is bigger than the Area of the rectangle.

Suppose the sum of all the sides in a square is this: 4 x A and the same is true of a rectangle, too.

Then, first, the area of the square is A^2.

And next, assuming that we have this: 0 < X < A and that one side in the rectangle is this: (A - X)

we can say that the side next to (A - X) is this: (A + X) because the sum of all the four sides in the rectangle has to be this: (4 x A), which equals the sum of all the sides in the square.

So now, the area of the square is this: A^2, whereas the area of the rectangle is this: (A^2 - X^2), which equals this: (A + X)(A - X).

Here we have given that the audit team is planning to examine a sample of control policies and procedures. assume that, based on the intended degree of reliance on internal control, the audit team wishes to control the risk of overreliance to 5%.

And we need to find sample size.

While we looking into the given question, we know that the tolerable rate of deviation from 7% to 5% on the sample size.

Let us consider that 100 be the sample size, then the reduction in 7% to 5%, tell that there is an 2% decrement in the sample size.

Therefore, it can be calculated as,

=> 100 x 2/100

=> 2

Here we already know that the risk of overreliance to 5%.
