ok ive doing fine on equations but when it came to these word problems...i need help!

The spread of Virus is modeled by the following function w/ respect to t=time=days; V(t)= -t^2+5t-7 where V(t) is the number of people since the first reported viral case was observed. use the "formal definition" of a derivative to find d/dt (V)(t)

thanks guys i appreciate any help!

In synthetic division and long division is it possible for there to be a zero remainder or no remander at all so
my answer w/ out a remainder would look like -1x+10x-25
and with a remainder it would look like 3x+2x+5-23/x+5

I really am not sure my question is really can a problems answer have no remainder at all?

Solve. and then unscramble your answers (when you convert into letters) for the next clue. These are probably easy, but it is the first step!

1. 4(5x-6)=-20+19x

2. 8x=16x-64

3. Square Root of 49

4. Square Root of 25

5. Square Root of 81 divided by 3

1=O

2=Z

3=L

4=K

5=R

6=T

7=A

8=S

9=T

10=P

All you are given is the lengths of the medians. You don't know what angles they make with each other. Is it possible to construct a triangle with this information.

What about if you are given only the three altitudes? Can you construct the triangle?

here's the question, it sounds like physics, but i'm in diff. eq and i don't have a clue how to start it...(we are currently working on nonhomogeneous diff eqs)

A front-loading washing machine is mounted on a thick rubber pad that acts like a spring; the weight W = mg (with g = 9.8 m/s2) of the machine depresses the pad exactly 0.13 cm. When its rotor spins at ω radians per second, the rotor exerts a vertical force
F0 cos(ωt)
Newtons on the machine. Neglecting friction, determine at what speed (in revolutions per minute) resonance vibrations will occur?
thanks!!
