You multiply two rational numbers by multiplying numerators and denominators with each other. So, you have

A rational number is a fraction where both numerator and denominator are integers. Since the product of two integers is an integer, the result fraction is also a rational number, because both
and
are integers.
[1] The median to the base passes through the top point (0,b) and the bottom point (0,0) since it is going straight down. The slope formula is

So, the slope of the median is (b-0)/(0-0) = b/0. Technically, this is undefined, but let's leave it this way for now.
[2] The base passes through the left point (-a,0) and the right point (a,0). Its slope must be (0-0)/(a-(-a)) = 0.
[3] We now check if the slopes are negative reciprocals. Flipping b/0 over and putting a negative sign gives:
b/0 -> - 0/b = 0
So the slopes are negative reciprocals, which means the lines are perpendicular.
Maybe let's just do the prime factorization.
40=2x2x2x5
answer:2^3x5
Answer:
One Kilogram
Step-by-step explanation:
1kg = 1000g
Step-by-step explanation:
yes that's true
if a^n=b
then
a^n/n=b^1/n
a=b^1/n
