Perform the indicated operations and simplify:

(2y)2 (2y3)


x2 + 13x +40 = 0


3x3 – 588x = 0


x2 + 2x = 63


49p2 – 112p + 64 = 0

Factor this trinomial completely: 21y2 + y – 2



THANKS FOR ALL THE HELP!!!!!

You are selling cases of mixed nuts and roasted peanuts. You can order no more than 400 pieces (cans of mixed nuts nad packages of roasted peanuts) and spend no more than $500. Mixed nuts cost $24/case, contain 12 cans and give you a profit of $20/case. Roasted peanuts cost $15/case, contain 20 packages and give a profit of $15/case. How many cases of each should you buy to maximize profit? What is your maximum profit?

Hi! This is a sample question from the math SAT II (level 2) test.

It says:

The number of hours of daylight, d, in Hartsville, can be modeled by:

d = (35/3) + (7/3)sin([2pi/365] * t), where t is the number of days after March 21. The day with the greatest number of daylight hours has how many MORE daylight hours than May 1?

How do you solve that?! I don't know how to find the maximum value of a trigonometric function (only a quadratic function). Please help! I'll pick a best answer TODAY! Thank you so much!
