Instantaneous Rate of Change if a ball is thrown straight up into the air with an initial velocity of 75 ft/s, its height in feet after t second is given by y = 75t-16t Find the average velocity include units, for time period beginning when t = 2 seconds and lasting

(i) 0.5 seconds
Average velocity:

(in) 0.1 seconds
Average velocity

(in) 0.01 seconds
Average velocity:

Finally based on the above results, guess what the instantaneous velocity of the ball is when t=2
Average velocity:

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;

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
