Point slope form says the line through (a,b) with slope m is
y - b = m(x - a)
Here that's
y - - 1 = -2(x - -4)
Answer: y + 1 = -2(x + 4)
The regular period is 2pi. If you look up or type in a graphing calculator you can see that's when the sine function starts to repeat itself.
If u r trying 2 find the absolute value of a positive number, the absolute value of it will not be a negative, it will always be a positive.
Bacteria growth occurs exponentially; bacteria divides into 2 every t minutes (similar to the penny doubling every day story). If one gets filled, and the contents divides once, there will be enough for 2 bottles; when these two are ready to divide, there will be enough for 4. This growth process begins very slowly - 1, 2, 4, 8, 16, 32; but it soon speeds up greatly, 64, 128, 256, 512, 1024, 2048.
Typically Geometry. But it depends on your level.
