Answer:
I think the first one
Step-by-step explanation:
Answer:
c. (1, 3)
Step-by-step explanation:
The coordinates that best suite the equation, given it the answer.
We make the composition of both functions:
f (x) = x ^ 2-1
g (x) = 2x-3
Then:
f (g (x)) = (2x-3) ^ 2-1
Rewriting:
f (g (x)) = 4x ^ 2-12x + 8
The domain of this function is all real numbers.
Equivalently
x: (-inf, inf)
answer:
x: (-inf, inf)
option 1.
Answer:
523.6
Step-by-step explanation:
V=πr^2(h/3)=π*10^2*(5/3)=523.59878
Power is work done per time and work done is force times distance. The power is found by multiplying the force(20N) and the distance(5m) and dividing the product by the time(5s)
(20*5)/5=20Nm/s OR 20 watts.
Therefore the power needed is 20 watts.
