Which of the following are true statements? Check all that apply.

The graph of f(x)=2√x will look like the graph of f(x)=√x but will shrink it horizontally by a factor of 1/2.
The graph of f(x)=2√x will look like the graph of f(x)=√x but will shrink it vertically by a factor of 1/2.
The graph of f(x)=2√x will look like the graph of f(x)=√x but will stretch it vertically by a factor of 1/2.
F(x)=2√x has the same domain and range a f(x)=√x

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
