addison and kelsey are running on a path modeled by x^2+y^2-10x-18y-378=0, where the distance is in meters. what is the maximum distance between the runners at any given time

Answers

Answer 1

The maximum distance between them is the diameter of the circle, which is of 44 units.

The equation of a circle of center [tex](x_0, y_0)[/tex] and radius r is given by:

[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]

The diameter is twice the radius, and is the maximum distance between two points on the same circle.

They are running on a circular path, modeled by:

[tex]x^2 + y^2 - 10x - 18y = 378[/tex]

Completing the squares, the equation is:

[tex](x - 5)^2 + (y - 9)^2 = 378 + 5^2 + 9^2[/tex]

[tex](x - 5)^2 + (y - 9)^2 = 378 + 25 + 81[/tex]

[tex](x - 5)^2 + (y - 9)^2 = 484[/tex]

Then, the radius is: [tex]\sqrt{484} = 22[/tex], which means that the maximum distance between the runners at any given time is of 44 units.

Harper knows he is 50 yards from school. The map on his phone shows that the school is 34 inch from his current location.
How far is Harper from home, if the map shows the distance as 3 inches?

Answers

Answer:

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

1. We know that 1 yard is 36 inches, therefore, 50 yards expressed in inches is:

(50)(36)=1800in

2. If he is 50 yards from school and the map shows that the school is 34 inches from his current location, when it shows 3 inches the real distance is:

(1800)(3in)/24in=158.82

3. If you can to express it in yards:

158.82/36=4.41yd

Therefore, the answer is: 158.82 inches or 4.41 yards.

The time it takes for an object dropped from a height to reach the ground is given by the function time (in seconds) =(1/4)√h where h is the initial height in feet. If an object dropped from a building takes 4 seconds to reach the ground what is height of the object was dropped from, to the nearest foot?

Answers

Answer:

256 ft

Step-by-step explanation:

Assuming f(t)=(1/4)√h, we can solve for h by setting 4=(1/4)√h.

4=(1/4)√h

16=√h

h= 16^2 =256 ft

Step-by-step explanation:

h = (4 ÷ ¼)²

h = (4 × 4)²

h = 16² = 256ft

Firstly you should try and make the denominator 100 and then whatever the numerator is should be after the decimal point. For example 1/10 would be 10/100 which would be 0.10.

The length of a rectangle is six times its width.
If the perimeter of the rectangle is 70 cm, find its length and width.

Answers

Answer:

Length = 30

Width = 5

Step-by-step explanation:

So the formula for perimeter is

P = 2L+2W

And we know that:

L = 6W

So then we put in all the information that we do know

70 = 2(6W)+2W

And pop that into a calculator and you get W=5

So now we put that information into L = 6W to get:

L = 6×5

L = 30

Answers

Hello!

Answer:

3(4+3g-10h)

Step-by-step explanation:

Hope this helps!

The GCF expression is 12+9g-30h is 3(4 + 3g - 10 h)

what is GCF?

A group of numbers' greatest common factor (GCF) is the biggest factor that all the numbers have in common.

For example, 12, 20, and 24 have two common factors: 2 and 4.

The largest is 4, so we say that the GCF of 12, 20, and 24 is 4.

Given:

12+9g-30h

Now, to find the GCF we have to factorize the numbers

12= 2 x 2  x3

9 = 3 x 3

30= 2x 3 x 5

So, the Greatest common factor is 3.

Thus, the GCF expression is 12+9g-30h is 3(4 + 3g - 10 h)

The amount of flour used is :

= 4/5 × 15 kg

= 12 kg

The amount of flour left is :

= 15 kg - 12 kg

= 3 kg

2.

5 : 3 = Red : Blue

The amound of blue paint :

So, the litres of blue paint did he use is 9 liters

!30 POINTS! How can I use this trapezoid to prove the Pythagorean Theorem?

Answers

Answer:

Pythagorean Theorem: c2 = a2 + b2

Find the area by adding the areas of the three triangles. The area of a right triangle is: A = ½bh

Two triangles are identical so you can just multiply the area of the first triangle by two: 2A1 = 2(½bh) = 2(½ab) = ab.

The total area of the trapezoid is : A1 + A2 = ab + ½c2

You multiply both sides by 2 to get rid of the ½: (a2 + 2ab + b2) = 2ab + c2

You subtract out the 2ab: a2 + b2 = c2.

Then what is left is the proof: a2 + b2 = c2
