Car value = 22000(1 - .4)^n n is the number of years -.4 = 40% decrease each year
10:48 PM to 7:12 am is 8 hrs 24 min this assumes you dreamt the 7:14 am time ....
2.8 trillion = 2,800,000,000,000 = 2.8 x 10^12 passwords
30 nanoseconds = .000 000 030 seconds = 3 x 10^(-8)
You can use the calculator to do this enter 30 divided by 1 000 000 000 then = and = again ....
Unit rate miles per minute = 26/148 = 0.175= 0.176 miles per minute (rounded)
If you want minutes per mile 148/26 = 5.69 min/mile
Gather 'like' terms
(-6x+3x) + (4y-5y) - 4 =
-3x + (-y) - 4
-3x - y -4
One variable 'y is already isolated as y =x-5 sub this value of y into the second equation to find 'x'
x + y = 9
x + (x-5) = 9
2x -5 = 9
2x = 14
x=7 Now that you have x : y= x-5 = 7-5 = 2 x,y = 7,2
One leg is given by 10 sqrt3 x sin 30
Other leg is given by 10 sqrt3 x sin 60
HAving trouble typing this morning.....
-3/2 +-sqrt(12.32)/2 =- 3/2+- 1.1916 = .254 , - 3.255 (corrected again)
Push the LOG key then the number 8000 then comma then the base...then = ...it will look like this:
log(8000,.89) = -77.12093458711378
Negative exponents becom positive exponents when they are move into the numerator from denominator or vice versa
y^0 = 1 also so you will have this
2x^3 * x^2 y^-2 / ((2y^3)-2 ) = 2 x^3 *x^2 * (2y^3)^2 / y^2 = 2 x^5 * 4 y^6 /y^2 = 8 x^5 y^4
