This will give us a cylinder with s surface area of A = 2π • w • h + 2π • w to the second power square units. <span>A right circular hollow </span>cylinder<span> is a 3D region enclosed by two right circular </span>cylinders<span> having the same axis and two parallel annular bases perpendicular to the </span>cylinders<span>' common axis which will be formed when you rotate the given by 360 degrees.</span>
Answer:
90.4°
Step-by-step explanation:
Use Law of Cosines to solve:
12² = 9² + 8² - 2(9)(8)Cos X
144 = 81 + 64 - 144Cos X
-1 = -144Cos X
-1/144 = Cos X
Cos^-1 (-1/144) = X
X = 90.39789056°
Answer:
The independent variable is s
The dependent variable is c
Step-by-step explanation:
Identify the independent and dependent variables:
The equation c = 0.09s gives the amount c (in dollars) of commission a salesperson receives for making a sale of s dollars.
c = 0.09s
Where
c = commission the salesperson makes
s = amount of sales
The variables in the equation are c and s
The independent variable is s
The dependent variable is c because it's value is determined by the amount of sales of the salesperson
