Answer:
Step-by-step explanation:
Given line = 30x - 5y = 5 or y = 6x + 1
so, the slope of the given line is 6.
now, let the line which is perpendicular to the given line be y = mx + c
where,
m = slope of the line
c = constant
As we know, if two lines are perpendicular to each other, the value of product of there slopes are -1.
so, slope of given line × slope of perpendicular line = -1
⇒ 6(m) = -1
⇒ m =
By substitutiong the value of m in the equation, we get;
⇒
For c,
as the point (0,-3) passes through the line, we get;
⇒
⇒
Hence,
The line which is perpendicular to the given line and passes through (0,-3) is .
Answer:
12 W
Step-by-step explanation:
Taking first case to establish the value of k
Substituting W with 90, I with 0.6 and R with 250 then
Now when resistance is 300 and current 0.2 then
