Answer:
the answer is (2,-6)
Step-by-step explanation:
Contrapositive is basically the converse of the statement. For example, the contrapositive of the statement "If the color is blue, then the fence is blue" is "If the color is not blue, the fence is not blue". Our answer choice that is correct is choice A.

Hi!
Let's first expand the cotangent of theta.
You'll probably know that tangent will be "y/x", or
, and cotangent is the reciprocal of this, meaning that it is "x/y" or
.
That means that we are now given this equation.

That'll multiply to:

We'll want a common denominator to add by multiplying
to both top and bottom of the second term:


Pythagorean Identity states that
, so substitute that in:

Which simplifies to:

Hope this helps!
5/6 is the simplest form. you divide 10 and 12 by 2 making 5 and 6.
<span>Diameter of a grain of sand = 2 x 10^{-4}
</span><span>Diameter of the average cell in the human body = 1 x 10^{-5}
</span>
Difference of diameter of grain of sand and cell of human body
= 2 x 10^{-4} - 1 x 10^{-5}
=

=

=

=

=

= 19 × 10^{-5}
Hence, the diameter of a grain of sand is
19 × 10^{-5} longer than the diameter of the average cell of the human body.
