Chad wants to buy some books over the Internet. Each book costs $10.01 and has a shipping cost of $9.96 per order. If Chad wants to spend no more than $50 for his books, which inequality shows the maximum number of books, p, that he can buy? (10 points)

9.96p − 10.01p ≤ 50, so p ≤ 1
9.96p + 10.01p ≤ 50, so p ≤ 2
9.96 − 10.01p ≤ 50, so p ≤ 3
9.96 + 10.01p ≤ 50, so p ≤ 4

What is the multiplicative rate of change of the function?

1/3
2/3

Jordan works at a bakery. The owner tells Jordan she wants to take 20% off a $75.00 cake. If the cake still doesn't sell, the owner will again reduce the price by 10%. Jordan tells the owner to reduce the original price by 30% because the sale price would be the same.

Is Jordan correct?

Yes, the owner's method and Jordan's method both equal a 30% discount off the original price.

Yes, the sale price for both the owner's method and Jordan's method is $52.50.

No, Jordan's method has a greater effect on the sale price.

No, the owner's method has a greater effect on the sale price

Line and angle relationships

A ball is thrown upward off of a 100 meter cliff with an initial velocity of 6 m/s. The function f(x)=-5x2+6x+100 (graphed below) represents this situation where x is time and y is the distance off of the ground.

e. What would the new function be? What kind of transformation is this?
f. Would you still use the same domain and range? Why or why not?
