Using pythagorean identities,tan(sin^-1(-5/13))= tan(arcsin(-5/13))
Let A = arcsin(-5/13) = -arcsin(5/13)
Thus, sin A = -5/13 and cos A = sqrt(1 - (5/13)^2) = 12/13.= tan(A)= sin(A) / cos(A)= -5/13 / (12/13)= -5/12

Answer:
the graph where it's going up (right)
Step-by-step explanation:
if you double 40 it will be 80. double 80 and you get 160 etc etc. this means the total bacteria only grows and the graph has to go all the way up
X is minus 30 over 7
So you can cross multiply and multiply the values.
Then you can solve it like a normal equation
-- It's exactly 10% shorter than 1 inch, and 92.5% shorter than 1 foot.
-- It's also approximately 0.01343 smoot (rounded).
-- It's also approximately 2.286 centimeters, or 22.86 millimeters,
or 0.0000142 mile.
-- It's also approximately 0.000 000 000 000 000 002 418 light-year.
You see, "9/10 inch" is known and understood precisely wherever inches are
used in the world (everywhere throughout Liberia, Burma, and the USA) exactly
because "inch" is a unit that's exactly defined and agreed on in all those places.
But when you come along and say "I don't know what an inch is, describe it to me
in terms of something else", then you throw people for a loop.
If you can tell us what other unit you want to measure with ... like a flower,
a finger, an animal, or something else that we're also familiar with, then
we'll compare "9/10 inch" to that item for you. But that won't be exact,
because all of those things come in different sizes, and none of them has
a standard size that everybody agrees on.
