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 Brainpower Read More Previous Play Next Rewind 10 seconds Move forward 10 seconds Unmute 0:00 / 0:00 Full screen 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 log3(27) = Y 3^y = 27 What is the conversion of 4^x = 16 log4(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, S = 10,000 - B Now you can plug that in for S in the other equation: 400 = .01(10,000 - B) + .05B 400 = 100 - .01B + .05B 400 = 100 + .04B 300 = .04B 300 * 25
