25x and then 2 at the top
For 30 hours Julio is paid 30r dollars.
For the extra 5 hours he worked he earns 5*1.4r = 7r dollars
So the equation is
30r + 7r = 436.60
37r = 436.60
r = 436.60 / 37 = 11.80
His normal hourly rate is $11.80 answer
Answer:
6x + 3h
Step-by-step explanation:
F(X) = 3x^2
F(X+h) = 3(X+h)^2
then F(X+h) - F(X) / h
= 3(X+h)^2 - 3x^2 / h
= 3(x^2 + 2hx + h^2) - 3x^2 / h
= 3x^2 + 6hx +3h^2 - 3x^2 / h
= 6hx + 3h^2 / h
= h (6x +3h) / h
= 6x + 3h
I hope this answer is correct
Hello,
The simpliest quadratic function is y=(x+3)(x-1)
or y=x²+2x-3
We first need dy/dx.
dy/dx = -2sin(x/2)(1/2)
dy/dx = -sin(x/2)
We now find d^2y/dx^2.
d^2y/dx^2 = -cos(x/2)(1/2)
d^2y/dx^2 = -(1/2)cos(x/2)
