Answer:
Step-by-step explanation:
2)
x^3 - 3x^2 -24x +7
Find the derivative of this: which is,
3x^2 - 6x -24
in order to find the minimum you must set it up equal to 0
0 = 3x^2 - 6x -24
0 = 3(x^2 -2x -8)
0 = (x-4)(x+2)
x= 4
x=-2
Ignore the negative 2 answer, because it is unrealistic!
Hence, velocity is: 4 cm/sec
3) and 8) aren't visible, hence, i can't answer them
9) a. (-1,1/2) is where the f is both decreasing and concave down as shown in the graph down below.

30w + 20g 2400
In this equation, the number of wreaths is represented with the variable 'w', and the number of garlands is represented the equation 'g'
Since the band only has to make at least 2400, the amount of money made must be equal to or more than 2400.
Good luck!
