Answer:
(x+3)(2x^2+5)
Step-by-step explanation:
A=g≈-32
v=⌠a dt since a≈-32
v=-32t+C, where C is the initial velocity, which we are told is 20 ft/s
v=-32t+20
h=⌠v dt
h=-32t^2/2+20t+C, where C is the initial height, so what is a reasonable initial height? How about 3 ft since we are swinging a bat around maybe our waist level... maybe :P
h=-16t^2+20t+3
Your choices may have made a different assumption about the initial height of course but you did not show your choices, but certainly it will be:
h(t)=-16t^2+20t+hi, where hi is the initial height in feet.
This of course ignores air resistance and flight dynamics of a spinning ball with seams, which will make a significant difference in real life :)
^they suck , but the answer is B <3
Answer:
The cost when the two companies charge the same is $7,703.
Step-by-step explanation:
Let 'x' represent the number of tons.
For x tons the first company will charge:
5297 + 200.50x
For x tons the second company will charge:
6500 + 100.25x
We want to find x so that both companies charge the same, that is:
5297 + 200.50x = 6500 + 100.25x
x = 12 tons
For 12 tons both companies will charge the same.
The cost charged for 12 tones is:
5297 + 200.50*12 = $7,703
Hope this Helps! :)
Answer:
y= (x - 2)(x - (3 + i))(x + (3 + i))
I think this is the answer.
