Answer:
2.58 seconds
Step-by-step explanation:
When you complete the square, you get ...
h = -16(t -9/16)^2 +60 +81/16
Then the solution for h=0 is ...
t = (x -9/16)^2 = 1041/256
t = (9 +√1041)/16 ≈ 2.57903 ≈ 2.58
It takes about 2.58 seconds for the ball to hit the ground.

Answer:
7,491,001 --> 7,500,000
Step-by-step explanation:
This is because rounding happens like this:
The rounding rule is: 5 and above rounds up, and 4 and under rounds down.
Here is a little rhyme for the rule: <em>5 and above rounds up like a dove. 4 and below, get down low!</em>
7,<u>4</u>91,001 --> you want to round the underlined digit. You round using the next digit to the right. The next digit over is the 9. Remember our rounding rule. Since 9 is above 5, the 4 would round up. Note - the digits after the rounded number always become zeros, even if you round up or down. So our new number is 7,500,000.
I hope I helped!
