The distance between M and C is √61 and distance between M and H is 13√2.

What is distance formula?

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula.

Assume that 'd' is the distance between A and B.

d =√(x2 - x1)² + (y2 - y1)²

Given coordinates:

M(6, -7) and a line that contains C(-6, -2) and H(-1, 10).

Now, distance between M and C

=√(-6 -6)² + (-2 + 7)²

=√36 + 25

= √61

and, MH

=√(-1-6)² + (10 +7)²

=√49+ 289

= √ 338

= 13√2

solve for x
2x-y=r

(Show solving steps please)

Answers

Answer:

x=r/2+y/2

Step-by-step explanation:

2x-y=r

you want x all by itself, move y first by adding y

2x = r + y

divide both r and y by 2 to leave x all by itself.

2x/2 = r/2 + y/2

2/2 = 1 so it's really 1x

x= r/2 + y/2

A project calls for three pieces of wood. The longest piece must be twice the length
of the middle-sized piece. The shortest piece must be 10 in. shorter than the middle-
sized piece. If a board 70 in. long is to be used, how long can each piece be?

Answers

Answer:

70,35,25

Step-by-step explanation:

Let longest piece = a = 70

Let medium piece = b = 35

Let shortest piece = c = 25

a=2b

70=2b

35=b

c+10=b

c+10=35

c=25

How are you supposed to graph #14?

Answers

Answer:

Y=mx+c

Step-by-step explanation:

The number in front of the x is the gradient. This shows how much the line goes up in the y axis for every square in the x axis. The number after the plus is the y intersect. This is where the line crosses the y axis. Start at the y intersect and draw the line. For this question, the gradient is 2, so the line goes up 2 squares on the y axis for every square on the x axis. The y intersect is 1, so it would cross the y axis at +1 on the y axis

The daily consumption C (in gallons) of diesel fuel on a farm is modeled by C = 30.3 + 21.6 sin(2Ď€t/365 + 10.9) where t is the time (in days), with t = 1 corresponding to January 1. What is the average daily fuel consumption? Which term of the model did you use? Explain.

Answers

The question is an illustration of the sine function.

The average daily fuel consumption is 30.3The vertical shift represents the average daily fuel consumption

The function is given as:

[tex]\mathbf{C = 30.3 + 21.6\sin(\frac{2\pi t}{365} + 10.0)}[/tex]

A sine function is represented as:

[tex]\mathbf{y = a\sin(bx - c) + d}[/tex]

Where d represents the vertical shift.

In this case, d represents the average rate

So, the average daily fuel consumption is 30.3

The term that represents the average daily fuel consumption is the vertical shift of the sine function.
