Answer:
You just read it
Step-by-step explanation:
When the penny hits the ground, h will = 0.
So: Set h(t) = 0 = -4.9t^2 + 0t + 150 m
Then 4.9t^2 = 150, and so t^2 = sqrt(150 / 4.9) = plus or minus 5.53 sec.
We can use only the positive root, as we're measuring time.
t = 5.5 sec (answer)
You doubled the investment in the product. You sold it for twice what you bought it for. So it increased by $750
Answer:
605/12 ft by 121/12 ft
Step-by-step explanation:
So, the dimensions of the dog run would be 5x as the length and x as the width.
The perimeter of this dog run would therefore be :
5x + 5x + x + x = 12x
From here, we know that 12x = 121 ft, so x = 121/12 ft
so the final dimensions of the dog run would be 605/12 ft by 121/12 ft
