1 answer:
(a) The dimensions of the base of the box are (8 -2x) and (10 -2x). The depth of the box is x. The volume is the product of these dimensions.
V = x(8 -2x)(10 -2x)
(b) A graphing calculator is suitable "technology". The process is ...
• write the equation in the calculator
• adjust the scaling so the curve fills the display area
• select the maximum point to reveal its coordinates
The value of x that maximizes box volume is about 1.5 inches.
V = x(8 -2x)(10 -2x)

Answer:
D. 4 real roots and 0 complex roots
Step-by-step explanation:
If I assume that the function you are saying is
There should be up to "4 roots," there can't be more or less than 4 total solutions. First, we need to check how many sign changes are there in this function. There are 3 positive real roots. Now lets check for negative roots.
There are is only 1 negative real root. Since we basically have 4 real roots, and the max is 4. There should be 4 real roots and 0 complex roots.
There are 12 face cards and 4 aces to choose from. For the first card, the probability of drawing a face is 
. Then the probability of drawing an ace second is 
.
So the probability of drawing these two particular cards in the given order is
So the probability of drawing these two particular cards in the given order is
