PLZ HELP Me
use vertical motion model: h=-16t^2+vt +5 where
• t is the time(in seconds) the object has been in the air
•v is the initial vertical velocity ( in feet second)
• s is the intial height (in feet)
a) write the equation that models the height of a grasshopper that jumps straight up from the ground with an initial vertical velocity of 12 feet per second
b) after how many seconds is the grasshopper 2 feet the ground?

The distributive property allows you to say that 3(x − 1) = 3x −

Astudent showed the steps below while solving the inequality |x-4|< 1 by graphing.

(co 3) the times that customers spend in a book store are normally distributed with a mean of 39.5 minutes and a standard deviation of 9.4 minutes. a random sample of 25 customers has a mean of 36.1 minutes or less. would this outcome be considered unusual, so that the store should reconsider its displays? no, the probability of this outcome at 0.035, would be considered usual, so there is no problem yes, the probability of this outcome at 0.035, would be considered unusual, so the display should be redone no the probability of this outcome at 0.359 would be considered usual, so there is no problem yes, the probability of this outcome at 0.965 would be considered unusual, so the display should be redone
