Answer:
Area will be 2(lb + bh + hl)
So 2*(12*9 + 9*4 + 4*12)
384 sqft
Answer:
cos theta = adj / hyp is positive (+/+)
Step-by-step explanation:
In this open interval, the hypotenuse (radius) is always positive, whereas the adjacent side is positive and the opposite side negative.
in this interval:
sin theta = opp / hyp is neg (-/+)
cos theta = adj / hyp is positive (+/+)
tan theta = opp / adj = (-/+) : negative
Here you go, I hope this helps
0.000000109 in scientific notation will look as it follows:
1.09 * 10^-7
or
<span>
1.09 E-7
It's the same as 1.09 * (-10000000)
I hope it'll give you some clue of scientific notation with decimals.</span>
Y = how far up
x = how far along
m = Slope or Gradient (how steep the line is)
b = value of y when x=0
How do you find "m" and "b"?
b is easy: just see where the line crosses the Y axis.
m (the Slope) needs some calculation:
m = Change in Y/change in X
