Answer:
The value of m is 1000 for r=5
Step-by-step explanation:
Given that m is proportional to the cube of r
It can be written as:
When the proportionality symbol is removed a proportionality constant is introduced in the equation.
Let k be the proportionality constant
Given
r=3,m=216
Putting the values
The equation will now become
Putting r = 5
Hence,
The value of m is 1000 for r=5
3n² - 8n + 4
3n² - 6n - 2n + 4
(3n - 2)(n - 2)
Answer:
A) 40
Step-by-step explanation:
The sum of the interior angles of a regular polygon is:
For a hexagon, we put n=6
Let x be the 6th interior angle, then
The largest interior angle is 140°
Therefore the least exterior angle will be:
The correct choice is A
The estimated portion of light bulbs that last more than 500 hours will be
x=∑xn=224/430=0.521=52.1%
