The coordinates of point Q after dilation will be (2,-1). The correct option is B.

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

Given that the coordinate is Q(8,-4). The point is dilated by a factor of 1/4.

The dilation of the point will be calculated as,

Q(8,-4) = Q'(8/4, -4 / 4)

Q(8,-4) = Q'(2, -1)

Hence the dilated point is Q'(2,-1).

The height of the tree is 17.32 feet.

Height is the measurement of a person's or object's vertical distance from the ground. It is usually expressed in units of meters or feet. Height is an important factor in determining physical characteristics, such as BMI, or Body Mass Index. Height can also be used to estimate the age of a person, and to measure the effects of a growth-promoting treatment. Height is also used in many sports, as it is often an advantage for athletes.

Using the tangent formula, the height of the tree is approximately 17.32 feet. To calculate this, take the tangent of 70 degrees (which is 1.19175) and multiply it by the 10 feet of distance.

The result is 11.9175 feet, which when rounded to the nearest hundredth is 17.32 feet.

Check to see if there is a constant rate of change to determine if a table of values represents a linear function. You're looking at a linear function if there is! You can learn how to determine whether a table of values represents a linear function in this tutorial.

If an equation is written in the form axe + by + c=0, where a, b, and c are real numbers and the coefficients of x and y, i.e., a and b, respectively, are not equal to zero, then it is said to be a linear equation in two variables. Examples of two-variable linear equations are 10x+4y = 3 and -x+5y = 2.

If A alone can do a piece of work in 6 days and B alone in 8 days, then A and B undertook to do it for $3200 and complete the work in 3 days with the help of C, then C would be paid 400 dollars.

Therefore the answer is $400.

This is a work and time problem that can be solved using the concept of rate of work. Let's call the amount to be paid to C as "x".

A can do 1 piece of work in 6 days. Therefore, his rate of work is 1/6.

B can do 1 piece of work in 8 days. Therefore, his rate of work is 1/8.

Amount of work A and B can do in 3 days is

= 3×(1/6) + 3×(1/8)

= 3×(1/6)×(4/4) + 3×(1/8)×(3/3)

= 12/24 + 9/24

= 21/24

= 7/8

So amount of work C doing is

= 1 - 7/8

= 1/8

As C do 1/8 amount of work, the amount C would receive is

= 3200 × (1/8)

= 400

One Kung Pao chicken contains 1620 calories. One Big Mac contains 500 calories.

What is an equation?

A mathematical statement made up of two expressions joined by an equal sign is known as an equation. 3x - 5 = 16 is an example of an equation. We get the value of the variable x as x = 7 after solving this equation.

Assume that one Kung Pao chicken content x calories and one Big Mac content y calories.

Given that one Kung Pao chicken and two Big Macs provide 2620 calories.

Two Kung Pao chickens and one Big Mac provide 3740 calories.

Now using the variable finding calories:

One Kung Pao chicken and two Big Macs provide x + 2y calories.

Two Kung Pao chickens and one Big Mac provide 2x + y calories.

The system of equations is:

x + 2y = 2620  ......(i)

2x + y = 3740  .....(ii)

Using the elimination method to solve the given equations.

Multiply equation (i) by 2 and subtract it from equation (ii)

2x + y = 3740

2x + 4y = 5240

(-)  (-)      (-)

_____________

      -3y = -1500

Divide both sides by -3:

y = 500.

Putting y = 500 in equation (i)

x + 2(500) = 2620

x + 1000 = 2620

x = 1620

There were 24 photos of Simon's motorbike in the album originally.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

Let x be the number of photos of Simon's motorbike in the album originally.

We know that the number of photos of his car became 12, so the number of photos of his car originally was 8.

We also know that the ratio of the number of photos of his car to his motorbike became 3:5.

So the number of photos of his car and his motorbike originally was x-4.

We can set up the following equation:

12/(x-4) = 3:5

We can cross-multiply and simplify to get:

3x - 12 = 60

3x = 60 + 12

3x = 72

x = 72/3

x = 24

The rate of increase in the circumference of the circle at the instant when the radius of the circle is 3 meters is 3 phi m/s

From the question, we have the following information :

1. Constant rate of increasing radius with respect of time (t)

  = [tex]\frac{dR}{dt}[/tex] = 0.5 m / s

2. Radius of circle is 3 meters ( 3m )

To find constant rate of increasing circumference, we have to know formula of circumference.  

We know that circumference = 2 π R

Constant rate of increasing circumference with respect of time (t) can be formulated from contant rate of increasing radius multiply with formula to find circumference

[tex]\frac{dC}{dt}[/tex] = 2πR [tex]\frac{dR}{dt}[/tex]

[tex]\frac{dC}{dt}[/tex] = 2πR ( 0.5 )

    = πR

From above equation, we know that the rate of increasing circumference is πR

When R = 3 m, we just simply subtitute πR with R=3

The constant rate will be :

Rate of increasing circumference = πR m/s

                                                        = π (3) m/s

                                                        = 3π m/s

The number of people that will attend each game is given as follows:

The number of attendees will be of 500 on the 857th game, which does not make sense in the context of this problem, as a football team plays at most nine home games during a season. (taking the NFL in context).

The logarithmic function for this problem is defined as follows:

[tex]a(g) = 10 - \log_3{(g + 1)}[/tex]

Hence the number of people that will attend the second home game, when g = 2, is given as follows:

[tex]a(2) = 10 - \log_3{(2 + 1)}[/tex]

a(2) = 10 - 1

a(2) = 9.

Hence 9,000 people, as a(g) is measured in thousands.

The number of people that will attend the eight home game is given as follows:

[tex]a(8) = 10 - \log_3{(8 + 1)}[/tex]

a(8) = 10 - 2

a(8) = 8. (8,000, considering the unit of a(g)).

The game in which 500 people will attend is obtained as follows:

[tex]0.5 = 10 - \log_3{(g + 1)}[/tex]

[tex]\log_3{(g + 1)} = 9.5[/tex]

Applying the cube to both sides, we have that:

g + 1 = 9.5³

g = 857.
