A unit rate would be a ratio where 1 is the denominator . . .

(2000 rotations)/(40 sec)

2000/40

200/4

50 rotations/sec

speed=\frac{number\ of\ revolutions}{time}\\number\ of\ revolutions=2000\\time=40s\\\\
speed=\frac{2000}{40s}=50\frac{rotations}{second}\\\\Answer\ is\ 50\frac{rotations}{second}.

Y=x^2+bx+c;(-2,3)
Maksim231197 [3]
<h3>Answer:  b = 4 and c = 7.</h3>

===============================================

Explanation:

Comparing y = x^2+bx+c to y = ax^2+bx+c, we see that a = 1.

The vertex given is (-2,3). In general, the vertex is (h,k). So h = -2 and k = 3.

Plug those three values into the vertex form below

y = a(x-h)^2 + k

y = 1(x-(-2))^2 + 3

y = (x+2)^2 + 3

Then expand everything out and simplify

y = x^2+4x+4 + 3

y = x^2+4x+7

We see that b = 4 and c = 7.
