The Domain will be the values "x" takes on... ok... notice the graph, horizontally starts off at x = -2 and keeps on going to +∞, so hmm that's the domain.
The common difference is essentially what u need to add to one number in the sequence to get the next
So previous number + common difference = next number after that
The common difference would be -8
Answer: 3:4, 16:18,
Step-by-step explanation:
The volume of a cone is V=(1/3)(area of the base)(height)= (1/3)(pi*r^2)(h)
r^2= (d/2)^2 = (d^2)/4. Given: V= 301.44cm^3 and h= 18cm.
r^2= V/[(1/3)(pi)(h)]
r^2= 3V/(pi)(h)
(d^2)/4= 3(301.44)/(3.14)(18)
d^2= 12(301.44)/(3.14)(18)
d^2= 63.967
d= 7.997
d~= 8cm.
Given ,
AB = BC
BC = CA
CA = 6 cm
This is an equilateral triangle as the first side is equal to the second side and the third side is equal to the second side which is equal to the first side . As all the sides are equal to 6 cm , this triangle is said to be an equilateral triangle .
∴ Triangle ABC is an equilateral triangle , where :- AB = BC = CA = 6 cm .
