Answer:
48 +j64 ohms
Step-by-step explanation:
The impedance of a series circuit is the sum ...
R + jXl -jXc
= 48 +j100 -j36
= 48 +j64 . . . . ohms
_____
<em>Additional comment</em>
"j" is the electrical engineer's name for √-1, because "i" is used to represent current.
Answer:
A
Step-by-step explanation:
Taking the square root of both sides, you get
which simplifies to
The square root of 180 is approximately 13.42 and since it is the plus or minus square root, the answer is A, -13.42, 13.42.
Answer:
y = 3x + 21
Step-by-step explanation:
Use the given slope and point to substitute into the point-slope formula
Answer:
It would be the first table because if you graph the points on a graph, it would get you a zero slope which is a horizontal line across the graph.
Hello from MrBillDoesMath!
Answer:
(x-8)^(1/3) +2
Discussion:
To find the inverse of a function swap the values of x and y in the original equation y = (x-2)^3 +8 and solve for y.
y = (x-2)^3 +8 => original function. swap x and y values
x = (y-2)^3 + 8 => subtract 8 from both sides
x - 8 = (y -2)^3 => take cube root of both sides
(x-8)^(1/3) = y - 2 => add 2 to both sides
(x-8)^(1/3) +2 = y => y is the inverse
Thank you,
MrB
