Slope-intercept form of the equation of the line that is perpendicular to -2x + 3y = 10 and contains P(10,-10)

Vlad [161]

Slope intercept: y = mx + b
3y = 2x + 10
Y = 2/3x + 10/3
Perpendicular = opposite sign and reciprocal slope
Y = -3/2x + b
-10 = -3/2(10) + b
-10 = -15 + b, b = 5
Equation: y = -3/2x + 5

The diameter of a bicycle wheel is 2 feet.About how many revolutions does the wheel make to travel 2 kilometers?Explain.Hint 1 k

RSB [31]

We can work out the circumference of the wheel by using the equation

C = πd

C = π × 2
C = 6.28318530718
C = 6 feet

If 1km is 3280 feet, 2km is 6560 feet

6560 ÷ 6 = 1093.33333333 (recurring)
= 1093

Therefore the bike wheels rolls (approximately) 1093 times to cover 2km.
