First you have to look to see if you can isolate h. to do this you need to divide 2g on both sidesmaking the equation into f/2g=h.
just an extra little fact, we divide the 2g because it was multiplied as 2gh, to move it to the other side you do the opposite to it, therefore it being division :)
2/3(3/8x16). 2/3(6). 4. The answer is 4 :)
Answer:
Equation of the circle (x-3)²+(y-5)²=(6.4)²
x² -6x +9 +y² -10y +25 = 40.96
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given endpoints of diameter P(−2, 1) and Q(8, 9)
Centre of circle = midpoint of diameter
Centre = 
Centre (h, k) = (3 , 5)
<u><em>Step(ii):-</em></u>
The distance of two end points
PQ = 

PQ = √164 = 12.8
Diameter d = 2r
radius r = d/2
Radius r = 6.4
<u><em>Final answer:-</em></u>
Equation of the circle
(x-h)²+(y-k)² = r²
(x-3)²+(y-5)²=(6.4)²
x² -6x +9 +y² -10y +25 = 40.96
x² -6x +y² -10y = 40.96-34
x² -6x +y² -10y -7= 0
Answer: $25
Step-by-step explanation:
Amp is the number in front of sine so its 1/2 aka D :)
