Answer:
See below
Step-by-step explanation:
The CENTER will de directly between the two given points
<u> h, k = -1,7 </u>
so...so far the circle eq is
(x+1)^2 + ( y-7)^2
the RADIUS is 1/2 of the distance between the given points
1/2 d = (using distance formula) = 1/2 sqrt 80 =<u> 4.472 </u>
then the equation of the circle in standard form
(x+1)^2 + (y-7)^2 = 20
The power of the man is 233.33 W
We'll begin by calculating the energy used by the man. This can be obtained as follow:
Mass (m) = 35 Kg
Height (h) = 0.50 m
Acceleration due to gravity (g) = 10 m/s²
<h3>Energy (E) =? </h3>
<h3>E = mgh </h3>
E = 35 × 10 × 0.5
<h3>E = 175 J</h3>
Thus the man used 175 J of energy.
Finally, we shall determine the power. This can be obtained as follow:
Energy (E) = 175 J
Time (t) = 0.75 s
<h3>Power (P) =? </h3>
<h3>Power = Energy / time </h3>
Power = 175 / 0.75
<h3>Power = 233.33 W </h3>
Therefore, the power of the man is 233.33 W

Answer:
x = 30
Step-by-step explanation:
m<E = [m(arc)AD - m(arc)BC]/2
50 = (130 - x)/2
100 = 130 - x
-x = -30
x = 30

Answer:
D) 6,191
Step-by-step explanation:
6000 + 100 = 6100
6100 + 90 = 6190
6190 + 1 = 6191
