Why is the sum of two odd numbers even?
1 answer:
Answer:
a) and b) in photo.
there is no point left outside the circles, then 11+15 is even.
c) yes it is, because if both numbers are odd, they will have one point outside the circles each, and those two points will form an other pair.
odd number: 2n+1
even number: 2m
(m and n represent any natural number)
2n+1 + 2k+1= <em>the sum of two odd numbers</em>
=2(n+k) +2
=2(n+k) +2 =2(n+k+1)
<em>the sum of 3 natural numbers will be a natural number too. let be m=n+k+1 with m n and k natural numbers.</em>
=2m <em>even number</em>

Answer:
Step-by-step explanation:
The mass of a bag of sugar, m = 1 kg = 0.001 g
Length of bag, l = 9.2 cm
Width of bag, b = 6 cm
Height of the bag, h = 14.1 cm
We need to find the density of the sugar bag.
Density = mass/volume
So,
So, the density of the bag is .
Using the concept of domain, the domain of (f.g)(x) is given by:
{x ∈ ℝ | x ≠ 3}
---------------------
- The domain of a function is given by all possible input values, that is, <u>on a graph, all values that the x-axis assumes.</u>
- In the graph, <u>function f assumes all real values.</u>
- Function g is not defined for x = 3, thus, it's domain is all real values except 3.
- Thus, the multiplication, as
, will also not be defined at x = 3, and the domain of the multiplication is:
{x ∈ ℝ | x ≠ 3}
