Used graphic calculator
Answer:
volume= 4×4×5
80
Therefore he can't pour all the water into the vase because the amount of water is 120cm³ whilst the vase is 80. An amount of water as that can't fill the vase
Answer:
236 cubic units (to 3 significant figures)
Step-by-step explanation:
volume of a cylinder =
r²h (where r = radius and h = height)
Therefore, volume =
x 5² x 3
=
x 25 x 3
= 75
= 236 cubic units (to 3 significant figures)
Answer:
f ○ g(x) = x and g ○ f(x) = x is the correct composition
Step-by-step explanation:
INVERSE FUNCTIONS: Two functions are said to be inverse of each other if for every y = f(x), there exists a function g(x),
such that x =
= g(y)
Now, here if we need to show tha two functions f(x) and g(x) are inverse functions of each other , then show that for every x:
1. f o g(x) = f(g(x))= x
2. g o f(x) = g(f(x)) = x
If any two functions satisfy these two conditions, then they are inverse of each other.
Answer:
the given equation is y=4/7x
reciprocating both sides you get y/x =7/4
now x and y are directly porportional to each other so
x=ky where k is the constant
or x/y=k ......................(2)
equating 1 and 2
k=7/4
