Answer:
8 cm
Step-by-step explanation:
volume of a cylinder is v=pi x r^2 x h
substitute in what we know
3785= pi x r^2 x 19
3785=59.69 x r^2
subtract 59.69 from both sides
3725.31=r^2
square root of 3725.31
61
square root of 61
= about 8
Question 1: C, x < -8 <---
Question 2: A, n>= -4
Answer:
Let 
View Graph
Step-by-step explanation:
Let
find the cutting points with respect to the axes.
We can say that g(x) = y, well then 
, if x=0 then 
with respect to x there are no cut points since it is an asymptote
To x=1 y≅2.718, x=-1 y≅0.049, x=2 y≅20.08, x=-2 y≅0.0067, this for plotting some values
Answer:
Torrance spends 16$ on his brother
Step-by-step explanation:
You have 100$
So, we have
x (brother) + x (sister) + x (mother) = 100
But, since 10$ less will be spent on the sister than the brother, it becomes (x - 10) and twice + 6$ is spent on the mom, it also becomes (2x + 6)
Our equation then becomes
(x - 10) + x + (2x + 6) = 100
X will end up equaling 26. This is how much is spent on the sister.
(x - 10) will be substituted for (26 - 10), which equals 16.
I'm not sure if this is right so you might want to check with somebody (since I may be wrong) I hope this helps you understand how to basically do it though. <3
