Answer:
8 ft
Step-by-step explanation:
Okay lets get our variables and notes down first, I'll use the most common terms for this.
Hypotenuse: 12 ft <-- The ladder is the hypotenuse
Leg: 9 <- The height of the top of the ladder on the house
Base: ? <- We need to solve for it.
Pythagorean Theorem says c²-a²=b²
c = Hypotenuse
a & b are both Legs and interchangeable
12²-9²=b²
144-81=b²
63=b²
=
=b which is approximately 7.93 which rounds up to 8

Answer:
<em>The voltage at the middle source is</em>
Step-by-step explanation:
<u>Voltage Sources in Series</u>
When two or more voltage sources are connected in series, the total voltage is the sum of the individual voltages of each source.
The figure shown has three voltage sources of values:
The sum of these voltages is:
Operating:
We know the total voltage is , thus:
Equating the real parts and the imaginary parts independently:
4+a=6
1+b=-3
Solving each equation:
a = 2
b = -4
The voltage at the middle source is
Answer:
Yes, this is A Linear Function!
Step-by-step explanation:
This is a linear function beacuse linear functions are straight lines on the graph as you may know. So when we graph these numbers it turns up as a straight increasing linear line.
