Answer:
180Pi or 565.4866776
Step-by-step explanation:
Volume formula for a cylinder is pir^2h
We know that the height is 45 and that the radius is 2 so plugging that in we get (pi)(4)(45) which gets us 180Pi or 565.4866776 (using 3.14)
Answer:
first one x≥0
Step-by-step explanation:
domain is what your x values are so x≥0 because on the x-axis starts at 0 inclusive and keeps going.
Answer:
Step-by-step explanation:
we have the ordered pairs
(8, –1) and (2, –5)
Find the slope
The formula to calculate the slope between two points is equal to
substitute the values in the formula
simplify
The equation of the line in point slope form is
we have
substitute
Convert to standard form
The equation of the line in standard form is equal
where
A is a positive integer
B and C are integers
we have
Multiply by 3 both sides to remove the fraction
apply distributive property right side
Group the variables in one side and the constants in the other side
---> equation in standard form
Answer:
197
Step-by-step explanation:
Sample proportion is; p^ = 12/50 = 0.24
Margin of error of 5% is given by the formula;
ME = (z_0.05) √[p^(1 - p^)/n]
Let's make n(number of sample) the subject.
n = ((z_0.05)/ME)²((p^)(1 - p^))
From tables, the z-score of 0.05 is 1.645
Thus;
n = ((1.645)/0.05)²(0.24(1 - 0.24))
n ≈ 197
The answer would be B. Ft3 (cubed)
