1/2 - 3/8 = 4/8 - 3/8 = 1/8
you have to find a common denominator before you can subtract. in this case it is 8
Answer:
60
Step-by-step explanation:
let's say the angle is x
tan x=2√21/2√7=1.73205...
tan inverse of it = 60
The formula for the volume of a cone is:
V= (1/3) x
x
x height
Since this is a quadratic equation, if the radius is multiplied by 3, then the volume is multiplied by its square, which is 9.
Hope this helps!
Answer:
A.
Step-by-step explanation:
Given: limit of f(x) exists at x = a
To choose: the correct option
Solution:
A limit is a value that a function approaches as the input approaches some value.
means that as x approaches to value a then f(x) approaches to value L.
A limit of a function f(x) exists at x = a if ![\lim_{x\rightarrow a^-}f(x)=\lim_{x\rightarrow a^+}f(x)=L](https://tex.z-dn.net/?f=%5Clim_%7Bx%5Crightarrow%20a%5E-%7Df%28x%29%3D%5Clim_%7Bx%5Crightarrow%20a%5E%2B%7Df%28x%29%3DL)
So, option A. is correct.
