Micah took out a student loan for $20,000, which began accruing interest immediately. He has chosen not to begin payment of the loan until he finishes his schooling. The table shows the balance of the loan while Micah is in school. Months Loan Balance 6 $20,608 12 $21,234 18 $21,879 24 $22,543 30 $23,228 36 $23,934 Assuming that the relationship is exponential, which is the best estimate of the loan balance after 4 years? A. $20,403 B. $24,890 C. $25,168 D. $25,410

Given: f(x) = 2x + 5 and g(x) = x2 and h(x) = -2x h(g(f( = x2+ vx+ x + y

Which inequality has a dashed boundary line when graphed ?

Suppose we have a set of small wooden blocks showing the 26 letters of the english alphabet, one letter per block. (think of scrabble tiles.) our set includes 10 copies of each letter. we place them into a bag and draw out one block at a time. (a) if we line up the letters on a rack as we draw them, how different ways coukl we fill a rack of 5 letters? (b) now suppose we just toss our chosen blocks into a pile, and whenever we draw a letter we already have, we put it back in the bag and draw again. how many different piles of 5 blocks could result? possible? piles will contain at least one repeated letter? (c) if we draw out 5 blocks wit hout looking at them, how many different piles are (d) if we draw out 5 blocks without looking at them, how many of the possible 2. (4) consider the following formula. 12 give two different proofs, one using the factorial formulas and the other combina torial.
