69.92 when you add them all up and divide it you get 69.92
Answer:
y = -1/3x + 2
Step-by-step explanation:
The gradient of the given line is 3 because (y = mx +c where m is the gradient)
Therefore, to find the gradient of the perpendicular line (at 90 degrees), you need to find the negative reciprocal.
The negative reciprocal of 3 is -1/3 because imagine if 3 = 3/1, to get the reciprocal, you flip it, and to get the negative, you just flip the sign.
Now we know that Line M is y = -1/3x + c, we need to find the y-intercept.
To do this, just input the point (3,1) into y = -1/3x + c, to get c. This is because we know (3,1) is on the line from the question.
So it would be 1 = (-1/3 x 3) +c
Which would be 1 = -1 +c
And so c = 2
Put everything together and you get y = -1/3x + 2
Step-by-step explanation:
18 seconds to hour
18÷3600= 0.005 hour
accelerstion= velocity÷ time
60 mph÷ 0.005 = 12,000m/h^2
Answer:
y = -x + 4
perp: m = 1
y + 4 = x - 3
y = x - 7
