Can you guys help me please

Answer:

The correct answer is 4

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data:

square rock garden:

side = 120 ft

circular grass yard:

circumference = 560 ft

Step 02:

area (covered by grass):

area rock garden:

area (rg) = s² = (120 ft)² = 14400 ft²

area circular yard:

area (cy) = π r²

circumference = 2 π r

560 = 2 * 3.14 * r

560 / ( 2 * 3.14) = r

89.17 ft = r

area (cy) = 3.14 * (89.17 ft)² = 24967.05 ft²

area (covered by grass) = area (cy) - area (rg) = 24967.05 ft² - 14400 ft²

area (covered by grass) = 10567.05 ft²

area (covered by grass) (square yards):

The answer is:

area (covered by grass) = 10567.05 ft²

area (covered by grass) = 1162.38 yd²

The shortest of all chords drawn through a point a taken in the interior of a given circle, is the one which is perpendicular to the diameter drawn through a.

Let us consider a point ‘a’ in the interior of a circle with center ‘O’ and radius ‘r’. Let ‘A’ and ‘B’ be the two endpoints of the chord passing through ‘a’.

We know, the length of a chord AB is given by

Length of AB = \(2√r^2 - 2r*cos(θ/2)\)

Where θ is the angle between OA and OB.

Now, for the chord to be perpendicular to the diameter, the angle θ must be 90°.

Therefore,

Length of AB =\(2√r^2 - 2r*cos(90°/2)\)

Length of AB = \(2√r^2 - 2r*0\)

Length of AB = 2r

Hence, we can conclude that the shortest of all chords drawn through a point a taken in the interior of a given circle, is the one which is perpendicular to the diameter drawn through a.

The value of x is 13 in the rhombus ABCD

A quadrilateral is a four-sided polygon, having four edges and four corners

In figure ABCD is a rhombus

Given as Angle ∠ A = (5x + 25)

Angle ∠ D = (7x - 1)

Since adjacent angles of a rhombus add up to 180°

(5x + 25) + (7x - 1) = 180 and both equal

So, 5x + 25 = 7x - 1

Rearrange the terms in the equation,

7x - 5x = 1 +25

2x = 26

x = 13

Step-by-step explanation:

We can either use long division or synthetic division to help us divide this. You could also factor to get your answer.

The cost of the truck with 3 passengers is A = $ 45

Given data ,

Let's denote the number of passengers as P and the weight of the truck in pounds as W.

For the base rate of $30 per vehicle, the equation can be written as:

Cost = $30

For additional passengers beyond the first two, the equation can be written as:

Cost += ($5) * (P - 2)

For excess weight over 4,000 pounds, the equation can be written as:

Cost += ($10) * (W - 4000) / 500

To find the cost of a truck that weighs 5,000 pounds with three passengers, we substitute the values into the equation:

Cost = $30 + ($5) * (3 - 2) + ($10) * (5000 - 4000) / 500

Simplifying the equation:

Cost = $30 + $5 + $10

Cost = $45

Hence , the cost of a truck that weighs 5,000 pounds with three passengers would be $45

Answer:

y(t) = 494 (1.03)^t

y(10) = 663,89

Step-by-step explanation:

An increase in population by 3% each year means that at the end of each year, the population is 1.03 times what it was at the start of the year

This increase in population continues for t years

Exponential growth model that represents the population y (in thousands) t years after the beginning of the decade is

y(t) = 494 (1.03)^t

Where,

y = population

t = number of years

Find y when t = 10

y(t) = 494 (1.03)^t

y(10) = 494 (1.03)^10

= 494 ( 1.3439)

= 663.8866

Approximately y(10) = 663.89

This means that after 10 years from when the population was 494,000, it increased to 663,89.

Face-centered tetragonal lattices are not listed among the 14 3D Bravais lattices because they can be described as a combination of two different Bravais lattices: the simple tetragonal lattice and the face-centered cubic lattice.

To understand why, let's consider the definition of a face-centered tetragonal lattice. It is characterized by a rectangular prism with edges of equal length and right angles between them. Additionally, it has lattice points at the corners of the prism and one additional lattice point at the center of each face.

However, this arrangement can be described as a combination of a simple tetragonal lattice and a face-centered cubic lattice.

The simple tetragonal lattice consists of lattice points only at the corners of the rectangular prism, while the face-centered cubic lattice has lattice points at the corners and one additional lattice point at the center of each face.

By combining these two lattices, we can obtain a structure that satisfies the conditions of a face-centered tetragonal lattice.

Therefore, the face-centered tetragonal lattice is not considered as a separate Bravais lattice but rather as a composite of the simple tetragonal and face-centered cubic lattices.

Here is a sketch to illustrate the arrangement:

```

       o-------o-------o

      /                   /

   /       o          /

 /                   /

o-------o-------o

```

The solid circles represent lattice points, and the lines represent the unit cell. The corners of the rectangular prism correspond to lattice points from the simple tetragonal lattice, while the centers of the faces correspond to lattice points from the face-centered cubic lattice. Together, they form the face-centered tetragonal arrangement.

By recognizing that face-centered tetragonal lattices can be described using a combination of simpler lattices, the need to list them as a separate 3D Bravais lattice is eliminated.

Answer: Choice C

\(0 \le d \le 2\)

Graph with filled in circles at d = 0 and d = 2, shading in between

==========================================

Explanation:

d = amount downloaded in gigabytes

The smallest amount is d = 0. We cannot download a negative amount of data, so this is why d = 0 is the smallest.

The largest amount allowed is d = 2. This is the cap that the ISP has set up.

So basically d can be anything between d = 0 and d = 2, including both endpoints. This means \(0 \le d \le 2\)

We use filled in circles for both endpoints to show to the reader "include these endpoints". Shading is done in between to show the entire solution set of possible d values. For instance d = 1 is in that region so it is possible to have this solution. Something like d = 4 is outside the region and not possible.

When x = 0, y = 2(0) - 2 = -2. So one point is (0, -2). When x = 1, y = 2(1) - 2 = 0. So another point is (1, 0).

To graph the equations 2x - y - 2 = 0, 4x - 3y - 24 = 0, and y + 4 = 0, we need to plot the points that satisfy each equation and connect them to form the lines.

1. Equation: 2x - y - 2 = 0

To plot this equation, we can rewrite it in slope-intercept form:

y = 2x - 2

Now we can choose some x-values and calculate the corresponding y-values to plot the points:

When x = 0, y = 2(0) - 2 = -2. So one point is (0, -2).

When x = 1, y = 2(1) - 2 = 0. So another point is (1, 0).

Plot these points on the graph and draw a line passing through them:

```

    |

    |

0   |     ● (1, 0)

    |

    |     ● (0, -2)

-2 __|_____________

    -2    0    2

```

2. Equation: 4x - 3y - 24 = 0

Again, let's rewrite this equation in slope-intercept form:

y = (4/3)x - 8

Using the same process, we can find points to plot:

When x = 0, y = (4/3)(0) - 8 = -8. So one point is (0, -8).

When x = 3, y = (4/3)(3) - 8 = 0. So another point is (3, 0).

Plot these points and draw the line:

```

    |

    |

0   |             ● (3, 0)

    |

    |                   ● (0, -8)

-8 __|______________________

    -2     0    2    4

```

3. Equation: y + 4 = 0

This equation represents a horizontal line parallel to the x-axis, passing through the point (0, -4).

Plot this point and draw the line:

```

    |

    |

-4   |       ● (0, -4)

    |

    |

    |______________________

    -2     0    2    4

``

So, the graph of the three equations would look like this:

```

    |

    |

0   |             ● (3, 0)                      ● (1, 0)

    |                   |                               |

    |                   |                               |

-4 __|___________________|_______________________________

    -2     0    2    4

```

Note that the lines representing the equations 2x - y - 2 = 0 and 4x - 3y - 24 = 0 intersect at the point (1, 0), which is the solution to the system of equations formed by these two lines. The line y + 4 = 0 represents a horizontal line parallel to the x-axis, located 4 units below the x-axis.

The value of X in the given equation is 0.048 (rounded to three decimals).

To solve for the value of X in the equation provided, let's substitute the given values into the equation step by step and solve for X.

We have:

a = 0.21

b = 1.8

c = 0.13

d = 0.09

The equation is:

a = b * (c - d) + d + x

Substituting the given values:

0.21 = 1.8 * (0.13 - 0.09) + 0.09 + x

Let's simplify the equation:

0.21 = 1.8 * 0.04 + 0.09 + x

Multiplying 1.8 by 0.04:

0.21 = 0.072 + 0.09 + x

Combining like terms:

0.21 = 0.162 + x

Now, let's isolate the variable X:

Subtracting 0.162 from both sides:

0.21 - 0.162 = x

Simplifying:

0.048 = x

Therefore, the value of X is 0.048 (rounded to three decimals).

In the given equation, when we substitute the given values, we find that X is equal to 0.048.
