What is 36x^9y^4/4x^7y^3
motikmotik
Get rid of all common factors.
36/4 = 9
x^9/x^7 = x^2
y^4/y^3 = y

\boxed{\frac{36x^9y^4}{4x^7y^3}=9x^2y}

Convert the complex number z = -12 + 5i from rectangular form to polar form.​
Paha777 [63]

Answer:

z=13(\cos 157\degree +i\sin157\degree)

Step-by-step explanation:

The given complex number is

z=-12+5i

The polar form of this complex number is;

z=r(\cos \theta +i\sin \theta), where

r=\sqrt{(-12)^2+5^2}

r=\sqrt{144+25}=\sqrt{169}=13

and

\theta =\tan^{-1}(\frac{5}{-12})

This implies that;

\theta=157\degree to the nearest degree.

Hence the polar form is

z=13(\cos 157\degree +i\sin157\degree)

The circumference (C) of a circle is 16cm. Which formula can you use to find the diameter (d) if you know that C= πd?
Dima020 [189]

The formula is d=C/π.

The diameter is 2 times the radius

The formula for the circumference using the radius is 2πr.

in order to do this backwards, we would have to do 16÷2÷π, but we're not looking for the radius.

Therefore, we take out the ÷2 part, which would be 16÷π

16 is the circumference

16÷π=d

d=C÷π
