The geometric sequence that tells the perimeter of each stage in the building of Koch's snowflake has a first term of 3 and a ra
kari74 [83]
An = a1 * r^(n-1)
n = term to find = 18
a1 = first term = 3
r = common ratio = 4/3
now we sub

a18 = 3 * 4/3^(18 - 1)
a18 = 3 * 4/3^17
a18 = 3 * 133
a18 = 399

Given that the square root function is only defined for non-negative numbers, define the domain of f in terms of c. {x | ≥ 0}
diamong [38]

Answer:

c:(0;+∞)

Step-by-step explanation:

Given the situation, that the square root function only allows you values above than "0" (not equal neither), then you must consider that every value above 0 belongs to it's domain.

Then, to express the domain, going from your most negative number, to your most possitive number (in this case all positive number, thats why we use infinite)  you must use the parenthesis wich means, you are not considering the value (in this case 0), but the value right after it, to the next value that as we said before, is inifinite. Also remember, that when you express a domain, and use infinite (despite it's going to negative way, or possitive way, it also goes with parenthesis).

Plz answer!! thanks

Answer:

x = 10

y = 40

Step-by-step explanation:

60° + (2x + 7y)° = 180° because these two angles are supplementary

So 2x + y would be equal to 60°

60° + (2x + 7y)° = 180° subtract 60 from both sides

2x + 7y = 120 and

2x + y = 60 multiply second equation by -1 and it will be -2x -y = -60 now add it to first equation

2x + 7y -2x - y = 120 - 60 -2x will eliminate 2x

6y = 60 divide both sides by 6

x = 10

if 2x + y = 60 the we need to replace x with the value we found

2×10 + y = 60

y = 40
