Answer:
Is irrational
Step-by-step explanation:
Let be a rational number, and be an irrational number. If their sum were rational, say , then we'd have
but is the difference between two rational numbers, and thus a rational number. But it also equals , which is irrational by hypothesis. Since we have a contradiction, we conclude that the sum of a rational and an irrational can't be rational.
Answer:
Their slope is the same. Perpendicular
Step-by-step explanation:
3x + 4y = 12
4y=12-3x
y=-3/4x+3
6x + 8y = 48
8y=48-6x
y=-3/4+6
The area of a circle with respect to its diameter is:
A=(πd^2)/4
If he plants roses in every other section, there will be half of the area remaining, so half of the area of the circle is:
A=(πd^2)/8, since d=8:
A=(64π)/8 m^2
A=8π m^2 and if you want an approximation:
A≈25.13 m^2 (to nearest hundredth of a square meter)
