Answer:
<h3>13.8</h3>
Step-by-step explanation:
if Points X and Z are on a number line and point Y partition line XZ into two parts where XY: YZ = 1:4, this can be expressed as;
XY/YZ = 1/4
cross multiply;
YZ = 4XY
Also, if The coordinate of X is 1.3, and the coordinate of Y is 3.8, then the distance XY will be expressed as XY = 3.8 - 1.3
XY = 2.5
YZ = 4(2.5)
YZ = 10
Since Y is at 3.8 and YZ is 10, then coordinate Z will be YZ + Y
coordinate of Z = 10+3.8
coordinate of Z = 13.8
Answer:
A
Step-by-step explanation:
Here, we want to find the value of ln (-7)
ln is same as Log to base e and mathematically , we have it for positive numbers only
For that of negative numbers, we get undefined results
However, by the use of special mathematical
methods, we have the answer for ln (-7) as;
1.94591015 + 3.14159265 i
As we can see, for the second part, the value for the coefficient of the complex number is pi and thus, we have the correct option as A
