Answer:
240
Step-by-step explanation:
The circuit's power is modeled by a quadratic function, whose graph is a parabola.
The maximum power is reached at the vertex.
So in order to find the maximum power, we need to find the vertex's y-coordinate.
We will start by finding the vertex's x-coordinate, and then plug that into P(c).
The vertex's x-coordinate is the average of the two zeros, so let's find those first.
-15c(c-8)=0, so either -15c or c-8 equals 0, so c=0 or c=8.
Now let's take the zeros' average:
(0+8)/2=4.
The vertex's x-coordinate of this parabola is 4. Now let's find P(4).
P(4)=-15(4)(4-8)
240.
The maximum power of this circuit is 240 watts.
PLEASE MARK BRAINLIEST AND VERTIFIED ANSWER!! I spent a lot of time on this... :P thank you!!
8 3/5 is between 8 and 9
so point D would be correct
Answer:
Below in bold.
Step-by-step explanation:
Area of a kite = 1/2 * D1 * D2 were D1 and D2 are the 2 diagonals
D1 = 5 + 2.5 = 7.5 and D2 = 2*44444.5 = 9
So area = 1/2 * 7.5 * 9
= 33.75.
500. I remember by the saying 5 or more let it soar 4 or less let it rest, meaning 5 or more round up, 4 or less leave it.
Answer:
Step-by-step explanation:
Please enclose the fractional coefficient inside parentheses: y= (1/2x) − 3 for greater clarity.
Make a table of ordered pairs:
x y = (1/2)x - 3
0 -3
1 (1/2)(1) - 3 = -2 1/2
3 (1/2)(3) - 3 = -3/2
The y-intercept is the point at which x = 0, and (from the table) is -3. Plot a dark dot at (0, -3).
Now graph (3, -3/2), leaving a dark dot.
Draw a line thrugh (0, -3) and (3, -3/2).
