Correct answer would be b. x-10. You can check this by writing out (x-10) and writing the other factor out. Then simplify (factor) out everything and you will get x^2 - 21x + 110.
It's d just d no exponents
Answer:
The variable d models Rachel's distance from her exit (in meters) t seconds after the cameras began recording the stunt. d = - 38t
Step-by-step explanation:
From given, we have, The expression that represents the Rachel's distance is given by, d = - 38t + 220
where, d represents the distance in meters
t represents the time in seconds
We know that, speed = distance by time. Therefore, we need to differentiate the given equation w.r.t to time to find the speed.
we have, d/dt (d) = d/dt [- 38t + 220]
| d/dt (d) | = | - 38 + 0 |
s = d/dt (d) = 38 m/s
Therefore, the speed of Rachel is 38 m/s.
Volume = Length x Width x Height
Volume = 8 x 5 x 2 = 80 in³
Answer: 80 in³
