Ingrid hit a golf ball. The height of the ball (in meters above the ground) ttt seconds after being hit is modeled by h(t)=-5t^2+30th(t)=−5t 2 +30th, left parenthesis, t, right parenthesis, equals, minus, 5, t, squared, plus, 30, t Ingrid wants to know when the ball reached its highest point. 1) Rewrite the function in a different form (factored or vertex) where the answer appears as a number in the equation. H(t)=h(t)=h, left parenthesis, t, right parenthesis, equals 2) How many seconds after being hit does the ball reach its highest point? Seconds

It appears that people who are mildly obese are less active than leaner people. one study looked at the average number of minutes per day that people spend standing or walking. among mildly obese people, the mean number of minutes of daily activity (standing or walking) is approximately normally distributed with mean 376 minutes and standard deviation 64 minutes. the mean number of minutes of daily activity for lean people is approximately normally distributed with mean 528 minutes and standard deviation 107 minutes. a researcher records the minutes of activity for an srs of 7 mildly obese people and an srs of 7 lean people. use z-scores rounded to two decimal places to answer the following: what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 mildly obese people exceeds 420 minutes? what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 lean people exceeds 420 minutes?
