Answer:
and 
y = StartFraction 3 + 6 StartRoot 2 EndRoot Over 4 EndFraction and y = StartFraction 3 minus 6 StartRoot 2 EndRoot Over 4 EndFraction
Step-by-step explanation:
The given quadratic equation is (4y - 3)² = 72
We have to solve this equation for y.
Now, 4y - 3 = ± 6√2
⇒ 4y = 3 ± 6√2
⇒ and
Therefore, the solution is y = StartFraction 3 + 6 StartRoot 2 EndRoot Over 4 EndFraction and y = StartFraction 3 minus 6 StartRoot 2 EndRoot Over 4 EndFraction (Answer)
Answer:
- left: a, 0.4A; b, 0.4A; c, 0.4A; d, 0.4A; e, 0.8A
- right: a, 0.4A; b, 0.2A; c, 0.4A, d, 0.2A; e, 0.6A
Step-by-step explanation:
The currents into and out of a single device are the same. The sum of currents into and out of a junction are the same.
<u>Left Circuit</u>
The two branches at the bottom of the circuit are identical, so will have the same current. The current in each branch will be half the current shown coming from the battery:
a = b = c = d = (0.8 A)/2 = 0.4 A
The current at e into the battery will be the same as the current shown coming out of the battery:
e = 0.8 A
__
<u>Right Circuit</u>
0.6 A is the sum of the currents into the two branches. The current in the bottom branch is shown as 0.2 A, so the current in the top branch must be 0.4 A. That way, the currents total 0.6 A.
As before, the current throughout any given branch is the same, so ...
a = c = 0.4 A
b = d = 0.2 A
e = 0.6 A
Answer: Radius
Step-by-step explanation: The radius of a circle is a segment that joins the center of the circle to a point on the circle.
The minute hand on a clock would start in the center and go outwards towards a certain number. However, the minute hand would not go the full length across the clock so it's not the diameter.
The circumference of a circle which is another way of saying the perimeter of the circle is the distance around the circle so it would not be the circumference.
This means that the minute hand would represent the radius of a clock.
