The square root of 72 is rational because the answer can be a real number.
Answer: y = 3x+2
Step-by-step explanation:
slope = (62-32)/(20-10)
point-slope form -> y - 32 = 3(x -10)
y = 3x+2
Answer:
I think its b)1.5 seconds sorry if I am wrong
Step-by-step explanation:
16t²=time
16t²=16²seconds
16² seconds=256 seconds
16t²+64=distance
256+64=320
320 feet=distance
so
256 seconds/320feet
=1.5seconds
Check the picture below.
so it hits the ground when y = 0, thus


since "t" is seconds it took, it can't be a negative amount.
