40% of what is = 400,000

Answer:

[tex]x^2 + y^2 - 40 = 0[/tex]

Step-by-step explanation:

Given

[tex](h_1,k_1) = (6,-2)[/tex]

[tex](h_2,k_2) = (-6,2)[/tex]

Required

Determine the equation of the circle

First, calculate the midpoint of the given coordinates:

[tex](h,k) = \frac{1}{2}(h_1+h_2,k_1+k_2)[/tex]

[tex](h,k) = \frac{1}{2}(6-6,-2+2)[/tex]

[tex](h,k) = \frac{1}{2}(0,0)[/tex]

[tex](h,k) = (0,0)[/tex]

Next, calculate the radius.

This is the distance between [tex](0,0)[/tex] calculated above and any of [tex](6,-2)[/tex] [tex](-6,2)[/tex]

Using:

[tex](0,0)[/tex] and [tex](-6,2)[/tex], the radius is:

[tex]r = \sqrt{(0 - (-6))^2 + (0-2)^2}[/tex]

[tex]r = \sqrt{40}[/tex]

The equation is then calculated using:

[tex](x - h)^2 + (y - k)^2 = r^2[/tex]

Where:

[tex]r = \sqrt{40}[/tex] and [tex](h,k) = (0,0)[/tex]

[tex](x - 0)^2 + (y - 0)^2 = (\sqrt{40})^2[/tex]

[tex](x )^2 + (y)^2 = 40[/tex]

[tex]x^2 + y^2 = 40[/tex]

[tex]x^2 + y^2 - 40 = 0[/tex]

A quadratic function has the possibility of two x-intercepts.

A quadratic function is one of the form f(x) = ax² + bx + c, where a, b, and c are numbers with a not equal to zero.

Given that a function having two x-intercepts

The graph of a quadratic function will always have one y-intercept and can have as many as two x-intercept.

Hence, a quadratic function has the possibility of two x-intercepts.

Answer:

1/3?

Step-by-step explanation:

Answer:OK SO Since the outcome of a coin toss is equiprobable, the probability of getting exactly two tails out of three is equal to the number of ways to get two tails out of three - aka - divided by the total number of possible coin flip outcomes - aka . Ergo, 3/8 is the probability.

Answer:

m=15

Step-by-step explanation:

m/9 + 2/3    

          x 3                         7/3  x 3 =  21/9

m/9 + 6/9 = 21/9

21-6=15

15/9 + 6/9 = 21/9 = 7/3

Answer: Circumference:  C = 2πr = 16.3

2(3.14)r = 16.3

r = 16.3/6.28

r = 2.5955414

Area:  A = πr2

A = 3.14(2.5955414)2

A = 21.15366242 in2

Rounded to nearest whole number the area is 21 in2

Step-by-step explanation:

* Lets revise some rules of a circle

- The circumference of a circle = 2πr , where r is the radius of it

- The area of the circle = πr²

* Lets solve the problem

∵ A circular plate has circumference 16.3 inches

∵ The circumference = 2πr

∵ π = 3.14

- Lets find the radius of the plate

∵ 16.3 = 2(3.14)r

∴ 16.3 = 6.28r

- Divide both sides by 6.28

∴ r = 16.3/6.28 = 2.5955 ≅ 2.6

∴ The radius of the plate is 2.6 inches

* Lets find the area of the plate

∵ The area = πr²

∵ π = 3.14

∵ 4 = 2.6

∴ The area = 3.14(2.6)² = 21.22 ≅ 21

* The area of the plate is 21 inches

Answer:

Step-by-step explanation:

r is the radius

Circumference = 2πr = 16.3

r = 16.3/(2π) = 8.15/π

Area = πr² = π(8.15/π)² = 8.15²/π ≈ 21.1 sq in

Answer:

Third week = 23.35 miles

Step-by-step explanation:

First week total miles = 15 miles

he would like to run 30% more miles each week than the week before

Second week = 15 miles + (30% of 15 miles)

= 15 + (30% * 15)

= 15 + (0.3 * 15)

= 15 + 4.5

= 19.5 miles

Second week = 19.5 miles

Third week = 19.5 miles + (30% of 19.5 miles)

= 19.5 + (30% * 19.5)

= 19.5 + (0.3 * 19.5)

= 19.5 + (5.85)

= 23.35 miles

Third week = 23.35 miles

Answer:

10√2 inches (second option)

Explanation:

visualise a square in your head. then, imagine a diagonal running through it. that diagonal would separate the square into two triangles. so to find the diagonal, we first need to find the length of the square (which would serve as the base and height of the triangle).

we can simply divide the perimeter by 4 to get the length of each side, which would then be 40 ÷ 4 = 10.

next, we can use the formula of the pythagorus theorum! it states that a² + b² = c², where a, b and c are represented by the following image:

for our equation, this would translate to 10² + 10² = c², and c would be the length of the diagonal.

100 + 100 = c²

200 = c²

in radical form, the square root of 200 would be 10√2. therefore, the length of the diagonal is 10√2 inches, which is the second option.

Answer:

89 times 53

Step-by-step explanation:

Answer:

I think 49 is the answer

Step-by-step explanation:

Because a straight angle measures 180 degrees so if one angle is 131 you just subtract 131 of 180 and it will give you the angle missing.

180-131=49

Answer:

49 degrees

Step-by-step explanation:

angles on a straight line add to 180

so 180 - 131

= 49

Answer: 24 [tex]in^{2}[/tex]

Step-by-step explanation:

A=1/2hb

to find lenth of triangle: the side of the square is 10 and on the top, the triangle takes up 10-6 in so it must be 4 in long

to find height, it is 16-10 in of of the square. so itmust be 6 in

so to find area:

A=1/2*6*4

= 1/2*24

Answer:

The box is 5 inches tall

Step-by-step explanation:

The given dimensions of the video games are;

The length of the video game, L = 15 inches

The width of the video game, W = 10 inches

The volume of the video game box, V = 750 cubic inches

Assuming that the shape of the video game box is a cuboid, we have;

The formula for the volume of a cuboid, V = Length, L × Width, W × Height, H

∴ V = L × W × H

The height of the cuboid, H = V/(L × W)...(1)

Where, for the video game box;

L = Length = 15 in.

W = Width = 10 in.

V = Volume = 750 in.³

Plugging in the values of the variables in equation (1) gives;

H =  V/(L × W) = 750 in.³/(15 in. × 10 in.) = 5 in.

The height of the box, H = 5 inches.

Step-by-step explanation:

To solve this, use the Pythagorean Theorem: a² + b² = c². You insert the measurements you have: 3² + b² = 5² or 9 + b² = 25. To solve this, subtract 9 from both sides: b² = 16. To solve for b (length) specifically, find the square root of 16: 4.
