If a cannonball is shot directly upward with a velocity of 224 ft/sec, its height, in feet, above the ground after t seconds is given by s(t)equals224 t minus 16 t squared. Find the velocity and the acceleration after t seconds. When does the cannonball reach its maximum height? What is the maximum height the cannonball reaches? When does it hit the ground?

answer: haha (: i’ll go see what it is

step-by-step explanation:

i think that you should ask google for the answer to that problem because if we don't know it google does

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;

a triangular prism is a 3 dimensional shape composed of triangles and rectangles. it is made from two triangular bases and three rectangular sides.
