Please help ASAP..will mark the first one as brainliest The height of a projectile can be described by the vertical motion model h(t) = - 16t2 + vt + h, where t is the time (in seconds) the object has been in the air, v is the initial vertical velocity (in feet per second), and h is the initial height (in feet). To catch a Frisbee, a dog leaps from the ground into the air with an initial vertical velocity of 28 feet per second.

What is the maximum height of the dog (to the nearest hundredth)? ft

At what time did the dog reach its maximum height (to the nearest hundredth)? seconds

After how many seconds does the dog reach the ground (to the nearest hundredth)? seconds

Please help ASAP

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;

c. 6tan80

step-by-step explanation:

it would be 4 over -2 divided by -1 over 3.

if you want a solution it would be 4

you flip it so it would be 4/-2 divided by 3/-1 then it would be 12/3 and you would simplify it to 4
