If its talking about the temperature decreased it would be -11 but it's asking for an integer
Answer:
9x² -5
Step-by-step explanation:
(f○g)(x) means f(g(x))
Put the definition of g(x) in place of x in the definition of f(x):
f(g(x)) = f(x²) = 9(x²) - 5
(f○g)(x) = 9x² - 5
Answer:
It's a parabola
Step-by-step explanation:
If you write the equation as
x =3y2
, you can see that you are in the form
f
(y)=3y2
. This is a quadratic polynomial in
y
, which means that it represents a parabola with axis parallel to the
x axis.
KE=1/2mv^2
50000=(0.5)(1000)v^2
v^2=50000/500
v^2=100
v=10 ms^-1
