Substitute the value 350 in for your velocity:
350 = 20 * sq rt(273+t)
divide both by 20 --> 17.5 = sq rt(273 +t)
square both to cancel out the sq rt --> 306.25 = 273 +t
then just subtract 273 from both to get 33.25 = t
When H = -5 the parabola will go right.
Let's assign the width to a variable, with that variable being x. the length is two times the width, so it would be 2x. the perimeter of a rectangle is length + length + width + width, so you would add 2x + 2x + x + x = 24 inches. combine like terms (x) to get 6x = 24. divide both sides by 6 to get x = 4. so the width (x) is 4, and the length (2x) is 8. the area of a rectangle is length times width, so multiply 4 * 8. that would get you 32 inches^2.
Answer:
A and C.
Step-by-step explanation:
It says that the a value increases by 2 but that still doesn't change the fact the graph is infinite. So the domain is still the same, and the range is still the same.
