Step-by-step explanation:
13.
Given


Required
Determine the distance between M and S
Distance (D) is calculated using:

Where








<em>Hence, the distance between M and S is 18 units</em>
<em></em>
14.
The coordinate of S and P are not given,
So, I'll just use (x,y) for P
i.e.

Required
Determine the coordinates of S
If S is 6 units above P, then the coordinates of S is

<em>i.e. we add the units to the y coordinate of P.</em>
K=am+3mx
K=m(a+3x)
m=K/(a+3x)
Answer: m=K/(a+3x)
The third one, this is because you take your y2 and y1 values (y2=0 and y1=9 because these are the two y values given to you from each coordinate) and subtract 0-9. then you do the same, but with the x2 and x1 values. so your x1 value is 3 and your x2 value is 0, so you subtract 0 from 3. divide your second answer from the first answer, to get a gradient of -1/3 x. now using the first coordinate (0,9) you know that the y coordinate is 9. as the x value =0, we know that the line is passing through the y axis at 9 so 9 is your y intercept. this gives you the equation -1/3x+9. hope this helped and wasn't too confusing!
Answer:
It will be 2.83 inches long on the drawing
Step-by-step explanation:
The scale we have is;
0.5 in to 3 ft
This;
x in to 17
17 * 0.5 = 3 * x
8.5 = 3x
x = 8.5/3
x = 2.83 inches
Answer:
C. 13
Step-by-step explanation:
Apply pythagorean theorem.
Thus:
Diagonal AV = √(12² + 5²)
AV = √(144 + 25)
AV = √169
AV = 13 cm
