yes because a theorem is an idea which occurs to be true in all cases. it is not a theory. definitions help with the understanding of theorems
hope this helps.
X^2 + 4x -12 = (x+6)(x-2)
so
(x+6)(x-2)
---------------- = x - 2
x + 6
f(x) = x -2
answer is B.
because
if x = -6
then y = -6 - 2 = -8
(-6,-8) is the order pair
13x6=78
12x5=60 (the two triangles are equals keep it like this)
12x6=72
5x5=25
78+60+72+25=235 cm
Hope this could help
The answer to this question is:
A circle is growing so that the radius is increasing at the rate of 2cm/min. How fast is the area of the circle changing at the instant the radius is 10cm? Include units in your answer.?
✔️I assume here the linear scale is changing at the rato of 5cm/min
✔️dR/dt=5(cm/min) (R - is the radius.... yrs, of the circle (not the side)
✔️The rate of area change would be d(pi*R^2)/dt=2pi*R*dR/dt.
✔️At the instant when R=20cm,this rate would be,
✔️2pi*20*5(cm^2/min)=200pi (cm^2/min) or, almost, 628 (cm^2/min)
