Answer:

A: $v(t)=-t^2+4t-5$

Step-by-step explanation:

Acceleration is second derivative of position, velocity is first derivative. Therefore, the velocity is the integral of acceleration.

$v(t)=\int\ {2t+4} \, dt$

Integrate:

$-t^2+4t+C$

V(0)=-5:

$-0^2+4(0)+C=-5\\C=-5$

Therefore, v(t):

$v(t)=-t^2+4t-5$

If it values at: 223,050 dolars, she has 2230.5 parcels of 100 dolars.

By paying 48 dolars, we have to divide these by the amount of 100s she has.

48/2230.5= .021 dolars per 100

Hope you get it!

X
X + 2
X + 4

3x + 6 = 258
3x + 6 - 6 = 258 - 6
3x = 252

X = 84
84 + 2 = 86
84 + 4 = 88
