Two wheel gears are connected by a chain. The larger gear has a radius of 5 centimeters and the smaller gear has a radius of 3 c

Answer:

2035.75 cm/min

Step-by-step explanation:

-Since the two gears are connected by the same chain, they have the same linear velocity.

-Linear velocity is distance covered over time:

$Speed=\frac{Distance}{Time}\\\\=\frac{Circumference}{Time}\\\\=\frac{36\times 3\times\pi\times 6}{1}\\\\=648\pi \ cm/min \ or \ 2035.75 cm/min$

Hence, the linear velocity of both gears is 2035.75 cm/min

I need help with this equation 20 points help quick

Answer:

The equation of the graph after translating one unit to the left is;

$y = \left | \dfrac{x}{2} - \dfrac{3}{2} \right |+3$

Step-by-step explanation:

The given equation is $y = \left | \dfrac{1}{2}\cdot x - 2 \right |+3$

We note that minimum value of y = 3, where 1/2·x - 2 = 0 and x = 4

Therefore, in moving one unit to the left, we have at the y-intercept where slope of the graph has become inverted (reflection of the real graph) we add one to the x value as follows;

$y = \left | \dfrac{1}{2}\cdot (x+1) - 2 \right |+3 = \left | \dfrac{x}{2} + \dfrac{1}{2} - 2 \right |+3 = \left | \dfrac{x}{2} - \dfrac{3}{2} \right |+3$
