Tay used `52` fruits altogether. Here are two equations, where `x` is the number of apples and `y` is the number of strawberries:

`y=3x`

`52=x+y`

How many of each type of fruit did Tay use?

The position of a moving particle is given by the position function: f(t)=-9t-t^2-0.2t^3+0.1t^4 a. at what time does the particle reverse direction? b. when is the displacement positive? (round one decimal place and answer in interval notation) c. when is the displacement negative? (round one decimal place and answer in interval notation) d. when is the particle’s acceleration positive? (round one decimal place and answer in interval notation) e. when is the particle’s acceleration negative? (round one decimal place and answer in interval notation)

F(x) = 1/x g(x)=x-4 can you evaluate (g*f)(0) ? why or why not?

If f(x) = 2x + 8 and g(x) = x4, what is (gº)?
