Please help, i need to raise my grade The formula for centripetal acceleration, a, is given in this formula, where v is the velocity of the object and r is the object's distance from the center of the circular path
a = v^2
-
r

Solve the formula for r

Step-by-step explanation:

To isolate r, we're going to need to do some algebraic manipulation.

Multiply both sides by r:

Divide both sides by a:

Hope this helps!

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

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;
