The inequality x^2 + 12x + 35>_0 has two critical points and three possible intervals for solutions. Choose each set of possible test points for the three intervals.

46 dollars is the answer.

step-by-step explanation:

6*6 = 36,         36+10=46

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

the radius is 2 times the diameter.
