What is 2^(5/2) - 2^(3/2) - ✔✔-** 2√2 **



2^(5-2) can be broken into:

2^4/2 == 2^2 == 4

so 4 2^1/2

or 4√2



2^3/2 can be broken into:

2^1 == 2

2^1/2 == √2

so 2√2



4√2 - 2√2 = 2√2



What is 5! - ✔✔-5 * 4 * 3 * 2 * 1



What is (2^4) * (2^5) - ✔✔-2^9



How do you calculate the determinant of a matrix - ✔✔-Imagine a 2x2 cube, where

top left = a

top right = b

bottom left = c

bottom right = d

, Determinant == (a/c) - (b/d)



What is the conversion of log\3\(27) = Y - ✔✔-3^y = 27



What is the conversion of 4^x = 16 - ✔✔-log\4\(16) = x



What is 2√10 * 2√3 - ✔✔-4√30



Factor (2x^5)-(2x^4)-(40x^3) - ✔✔-(2x^3)(x^2-x-20)



How do you determine if 2 lines are parallel? - ✔✔-Convert to y=mx+b

If both x's are the same, it is parallel



What is the slope of a line that crosses (5,6) and has a y-int of (0,2) - ✔✔-4/5



James has $10,000. He puts some of his money in a savings account that yields 1% annually. He invests
the rest in bonds that yield 5% annually. If after one year, James earns a total of $400 from both the
savings and bond investment, how much money did he put in his savings account? - ✔✔-* 7500 *



So, you know the interest is .01 on the saving and .05 on the bonds, profit is set to 400, so :



400 = .01S + .05B



You also know that S + B = 10,000, so:



10,000 = S + B



You can isolate S,
