Answer:
20π or 62.8
Step-by-step explanation:
Volume of a cone = 1/3πr²h
1/3(π)(2)²9
= 12π or 37.7
Volume of a hemisphere = 2πr²/3
2(π)(2)²
= 8π or 25.1
Total Volume = 20π or 62.8

You switched the numbers 2 and 3 btw
Answer:
64 sodas and 32 hot dogs
Step-by-step explanation:
192 divide by 2 = 96. 96 divide by 3 = 32. 32 +32 =64 because there was 2 times as many sodas sold.64 +32=96.
Answer:
Step-by-step explanation:
The given function is .
The domain refers to all values of x for which this function is defined.
Recall that: the domain of 
is 
And we know is the reciprocal of .
Therefore the complement of the domain of which is ![(-\infty,-1]\cup [1,+\infty)](https://tex.z-dn.net/?f=%28-%5Cinfty%2C-1%5D%5Ccup%20%5B1%2C%2B%5Cinfty%29)
is the domain of
the discriminant b^2 - 4ac when the equation is in the form of ax^2 +bx+c=0
13x^2-16x = x^2 -x
we need to get in it the standard form
subtract x^2 from each side
12x^2 -16x = -x
add x to each side
12x^2 -15x = 0
12x^2 -15x -0 =0
a=12 b=-15 c=0
b^2 -4ac
the discriminant = b^2
b^2 = (-15)2 = 225
