Kylie swam 6 feet below sea level and Bryan swam 8 feet below sea level. Find the difference between the absolute values for each depth.

Answers

Answer 1

The difference between the absolute values of Kylie's and Bryan's depth is 2 feet.

Here, we are given that Kylie swam 6 feet below the sea level and Bryan swam 8 feet below sea level.

This implies,

Kylie's distance from the ground level = -6 feet

and Bryan's distance from the ground level = -8 feet

We need to find the difference between the absolute values of their depth.

Thus, we ignore the minus (-) sign and find the difference as follows-absolute difference = | 6 - 8 |

difference = 2 feet

Thus, the difference between the absolute values of their depth comes out to be 2 feet.

Find the center and the radius of each circle. x²+(y-4)²=11

Answers

The equation of the circle x^2 + (y - 4)^2 = 11 has a radius of √11 and a center located at (0 , 4).

The standard form of the equation of  circle is given by

(x - h)^2 + (y - k)^2 = r^2

where (h , k) is the location of the center and r is the radius of the circle.

On the other hand, the general form of the equation of  circle is given by

x^2 + y^2 + Dx + Ey + F = 0

where D = -2h, E = -2k, and F = h^2 + k^2 -r^2.

If the equation of the circle, x^2 + (y - 4)^2 = 11, is in standard form, then

h = 0

k = 4

r = √11

Hence, the equation of the circle x^2 + (y - 4)^2 = 11 has a radius of √11 and a center located at (0 , 4).

The cost of renting a pool at an aquatic center is either 30 per hour or 20 per hour with a 40 non-refundable deposit. For how many hours is the cost of renting a pool the same for both plans?

Answers

If the cost of renting a pool at an aquatic center is either 30 per hour or 20 per hour with a 40 non-refundable deposit, then the cost of renting the pool is the same for both plans for 4 hours.

The number of hours for which the cost of renting the pool will be the same for both plans can be calculated by using an algebraic expression.

An algebraic expression is a type of equation that consists of both numbers and letters.

An algebraic expression for this problem can be given as,

30(x) = 20(x) + 40

Where x is equal to the number of hours.

The value of x can be calculated by rearranging the equation,

30(x) - 20(x) = 40

10(x) = 40

x = 40 ÷ 10

x = 4

Thus, the number of hours for which the cost of renting the pool same for both plans is 4 hours.

y varies directly with x . Explain your answer.If x is doubled, what happens to y ?

Answers

If x is doubled then the value of y is also doubled.

What is direct variation?

A sort of proportionality known as "direct variation" occurs when one quantity immediately changes in response to a change in another variable. This suggests that if one number increases, the other quantity will also rise proportionately. Similar to the last example, if one quantity declines, the other amount likewise declines. The link between direct variation and the graph will be linear, resulting in a straight line.

Rotation symmetry is also called mirror symmetry.

Rotational symmetry, also known as radial symmetry in geometry, is the property a shape has when it looks the same after some rotation by a partial turn. An object's degree of rotational symmetry is the number of distinct orientations in which it looks exactly the same for each rotation.

Certain geometric objects are partially symmetrical when rotated at certain angles such as squares rotated at 90°, however, the only geometric objects that are fully rotationally symmetric at any angle are spheres, circles, and other spheroids

Rotational symmetry is symmetry with respect to some or all rotations in m-dimensional Euclidean space. Rotations are direct isometries, i.e., isometries preserving orientation.

Symmetry with respect to all rotations about all points implies translational symmetry with respect to all translations.

Farmer ed has meters of​ fencing, and wants to enclose a rectangular plot that borders on a river. If farmer ed does not fence the side along the​ river, what is the largest area that can be​ enclosed?.

Answers

The largest area that can be enclosed will be 2812.5 square meters.

The perimeter of a rectangle is given as:

2L + 2W  ∴ L = length and W = width

As the farmer does not want to fence the side along the river, then the formula will be:

P = L + 2w

Now

150 = L + 2w

L = 150 - 2w

Here the area is LW

Area = (150 - 2W)(W)

After solving we get

150 - 2W = 0 or W = 0

150 - 2W = 0

2W = 150

W = 75

Now, there are two solutions whether 0 or 75

Let's find their average 0+75 / 2 = 37.5

Now L = 150 - 2(37.5)

L = 150 - 75

L = 75

As the dimensions are L = 75 and W = 37.5

Area = L x W = 75 x 37.5 = 2812.5 square meters

Find the sum of each infinite geometric series. 6+5+ 25/6 + . . .

Answers

The sum of the infinite geometric series 6+5+ 25/6 + . .  is S = 36

The given geometric series is:

  6 + 5 +  25/6 + . . .

The common ratio (r) of a geometric series is given by:

  r = a(n) / a(n - 1)

Notice that in the given series:

a(1) = 6

a(2) = 5

a(3) = 25/6

Hence, the common ratio is

   r = a(2) / a(1) = 5/6

Since 0 < r < 1, the series is convergent and the sum exists.

Use the sum formula:

S = a(1) / (1 - r)

Substitute a(1) 6 and r = 5/6 into the formula:

S = 6 / (1 - 5/6)

Answers

The point slope form of (1,10) and (5,42) is (y - 10) = 8(x - 1).

How to find the point slope form?

A straight line is represented using its slope and a point on the line using point slope form. In other words, the point slope form is used to determine the equation of a line whose slope is "m" and passes through the point (x1, y1).

given that

the coordinates points are (1, 10) and (5,42)

(x1,y1) = (1,10)

(x2, y2) = (5,42)

The formula of point-slope is

(y - y1) = m(x - x1)

Here,

x1 = 1 and y1 = 10 but we don't know the value of m.

now,find the value of m using the following formula

[tex]m = \frac{(y2 - y1)}{(x2 - x1)} [/tex]

now, substitute the values, we get

[tex]m = \frac{(42 - 10)}{(5 - 1)} [/tex]

[tex]m = \frac{30}{4} [/tex]

m = 8

so, the value of m is 8.

substitute these values into the point-slope formula

(y - 10) = 8(x - 1)

A table and a graph for that function are provided below.

How to create a table and graph that represents the amount you pay?

Here we know that the entrance fee to the fair is $15, and the cost of each ride on the fair is $2.50

So, if you go to the fair and enter in x rides, the total cost for that will be modeled by the linear function:

c(x) = $15 + $2.50*x

Now let's find a table, to do that we just need to evaluate the function in some values of x, I will use x = 0, x = 1 and x = 2, we will get:

C(0) = $15 + $2.50*0 = $15

C(1) = $15 + $2.50*1 = $17.50

c(2) = $15 + $2.50*2 = $20.00

Then we can write the table:

Number of rides |||    Cost

      0                          $15

       1                          $17.50

       2                         $20.00
