Answer:
= 3√3 + 3i
Step-by-step explanation:
Cos 30° = √3/2
Sin 30° = 1/2
Therefore;
z = 6 (cos 30° + i6 sin 30°)
= 6 (√3/2) + i 6 (1/2)
= 3√3 + 3i
Step-by-step explanation:
Just sub 4 into where n is
During the birthday 4/7 of the cake was eaten so it remained 1-4/7=3/7
the next day 1/2 of 3/7 was eaten what remained is 3/7 divide by 1/2
to divide we invert the second fraction (1/2) and multiply 3/7
3/7 x 2/1=6/7
Answer:
Domain: [-8,inf)
Range: [-3,5]
Function: Yes
Step-by-step explanation:
First, this relation is a function because x's never repeat. The domain is every x-value that the graph covers, on this graph x's start at -8, which is included, and then continue forever. So the domain should be written as [-8,inf) because it is from least to greatest and the bracket shows -8 is included. The range is the y-values the graph covers. On this, the highest y is 5, and then the graph flattens at -3, both points are included. So the range must be [-3,5].
