Answer: the mean is 4 the meadian is 2.5 and 6.5

and the range is 9

Step-by-step explanation: i may not be right since i havent done this kinda work in a long time but im pretty sure this is right. cause i graphed it out and the mean is the middle while the median is like the 2/4 and the range is the highest - the lowest number

So the right answer is none of the above

Answer:

9.81*10 (you have to add that tiny six next to the 0)

Step-by-step explanation:

Answer:

9.81 x 10^6

Answer:

11.25

Step-by-step explanation:

8x+11=180-79

8x+11=101

8x=90

x=11.25

By angle sum property the value of x in the expression (2 x + 10) +  (6 x + 1) +79 =180  is 11.25

The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.

2 horizontal and parallel lines are intersected by 2 diagonal lines to form a triangle with exterior angles.

The top angle of the triangle is (2 x + 10) degrees. The bottom right angle of the triangle is 79 degrees.

The exterior angle to the bottom left angle is (6 x + 1) degrees.

By angle sum property

(2 x + 10) +  (6 x + 1) +79 =180

8x+11 + 79 =180

8x+11=180-79

8x+11 =101

8x = 90

x = 11.25

Answer:

For x(θ) = 3cosθ + 2

y² = [9x²/(x - 2)²] - x²

For x(θ) = 3cosθ + 2

x² = [4y²/(y - 1)²] - y²

Step-by-step explanation:

Given the following equivalence:

x² + y² = r²

r = √(x² + y²)

x = rcosθ

cosθ = x/r

y = rsinθ

sinθ = y/r

Applying these to the given equations,

x(θ) = 3cosθ + 2

x = 3(x/r) + 2

xr = 3x + 2r

(x - 2)r = 3x

r = 3x/(x - 2)

Square both sides

r² = 9x²/(x - 2)²

(x - 2)²r² = 9x²

(x - 2)²(x² + y²) = 9x²

(x² + y²) = 9x²/(x - 2)²

y² = [9x²/(x - 2)²] - x²

y(θ) = 2sinθ - 1

y = 2y/r - 1

yr = 2y - r

(y - 1)r = 2y

r = 2y/(y - 1)

Square both sides

r² = 4y²/(y - 1)²

x² + y² = 4y²/(y - 1)²

x² = [4y²/(y - 1)²] - y²

Answer & Step-by-step explanation:

You are supposed to write the equation you would use to solve for x.

The triangle is a right triangle, classified by it's 90° angle, or right angle. This means that you can use the Pythagorean theorem:

[tex]a^2+b^2=c^2[/tex]

(a) and (b) are the legs and (c) is the hypotenuse. The hypotenuse is always the longest side and opposite the 90° angle. Insert the given values into the formula:

[tex]4^2+7^2=x^2[/tex]

Enter this equation into the boxes, and done.

Answer:

60cm=60.5cm

96.3cm=96.35cm

The upper bound lengths are 60.4 cm and 96.34 cm for the given lengths of 60 cm and 96.3 cm.

The upper bound for the given value is the numerical value that is rounded for the next value of the given value.

the Lower bound for the given value is the numerical value that is rounded for the previous value or the estimated value of the given value.

a) 60 cm - this is rounded off for the values,

Lower bound - 59.5 cm and Upper bound - 60.4 cm

b) 96.3 cm - this is rounded off for the values,

Lower bound - 96.25 cm and Upper bound - 96.34 cm (rounded to the nearest tenth)

So,

The upper bounds for the given lengths are 60.4 cm and 96.34 cm.

Answer:

Hi Gracie pretty sure the answer is 4/3, -2

Step-by-step explanation:

The zeroes of the function f(x) = (3x − 4)(x + 2) is 4/3, -2 option (3) and option (5) are correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

f(x) = (3x - 4)(x +2)

To find the zeroes of the function:

Applying zero product property:

(3x - 4)(x +2)  = 0

The above equation represents a quadratic equation,

As we know, Any equation of the form[tex]\rm ax^2+bx+c=0[/tex]  where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

3x - 4 = 0

3x = 4

x = 4/3

or

x + 2 = 0

x = -2

Thus, the zeroes of the function f(x) = (3x − 4)(x + 2) is 4/3, -2 option (3) and option (5) are correct.

The image point of  (8, 4) is (6, 2).

A translation is a geometric change in Euclidean geometry that involves moving each point in a figure, shape, or space by the same amount in one direction. A translation may alternatively be thought of as moving the origin of the coordinate system or as adding a constant vector to each point.

Given:

The point (8, 4).

To find the image point:

The translation rule:

The image point of (8, 4),

= (8 - 2, 4 - 2)

Answer:

A = 78.5 cm²

Step-by-step explanation:

Area of Circle = πr²

A = (3.14)(5)²

A = (3.14)(25)

A = 78.5 cm²

The area formula of a circle is r² x π.

With that being said, we can now substitute in our radius value.

(5)² x π

From there, we can find the square root of the radius.

(25) x π

And then we can multiply by pi to solve.

78.539816..

Finally, we'll round to the nearest tenth to get our answer.

78.5

Therefore, the area of the circle is 78.5 cm.

Answer:

The numbers are 4 and 1

Step-by-step explanation:

Let x and y be the numbers

Quotient is division

x/y = 4

x-y =3

Taking the first equation and multiplying each side by y

x = 4y

Replacing into the second equation

4y -y = 3

3y = 3

Divide by 3

3y/3 = 3/3

y=1

Now we can find x

x -y =3

x-1 =3

Add 1 to each side

x= 4

The vectors that have the same image for Hugo and Nemo are [3, 3].

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

To find the reflection of a vector v across the line y = -x, we can use the formula:

reflection(v) = R×v × R

where R is the reflection matrix given by:

R = [0 1]

[1 0]

To find the rotation of a vector v by 180° counterclockwise about the origin, we can use the formula:

rotation(v) = Rθ × v

where Rθ is the rotation matrix given by:

Rθ = [-1 0]

[0 -1]

Let's apply these transformations to each vector and see which ones have the same image for both Hugo and Nemo:

Reflection(d) = R × d × R = [0 1] × [3, 3] × [0 1] = [3, 3]

Rotation(d) = Rθ × d = [-3, -3]

These two vectors are equal.

Therefore, the vectors that have the same image for Hugo and Nemo are [3, 3].

Answer:

[tex]\sqrt{2} a[/tex]

Step-by-step explanation:

The distance between point (x1,y1) and (x2,y2) on a coordinate plane is given by expression [tex]\sqrt{(x1-x2)^2+(y1-y2)^2}[/tex]

In the problem given coordinate points are

(0, a) and (a, 0).

Thus, distance between these points are given by

[tex]distance = \sqrt{(x1-x2)^2+(y1-y2)^2}\\=>distance = \sqrt{(0-a)^2+(a-0)^2}\\=>distance = \sqrt{(a)^2+(a)^2}\\\\=>distance = \sqrt{2a^2}\\=>distance = \sqrt{2} a[/tex]

Thus , expression [tex]\sqrt{2} a[/tex] gives the distance between point (0, a) and point (a, 0) on a coordinate grid.
