So since we know that the post is 40 yards away, plug in 40 into the x variable of the equation to solve. If y is greater than 10 when x = 40, then it made it over. If y is less than 10 when x = 40, then it does not make it over. $y=-0.03*40^2+1.6*40$

Firstly, solve the exponent: $y=-0.03*1600+1.6*40$

Next, solve the multiplications: $y=-48+64$

Lastly, solve the addition and your answer will be: $y=16$

Since the football was 16 ft high, as opposed to the goal post's 10 ft, when it was at the goal post, it had successfully gone over the post. And since 16 ft is 6 ft higher than 10 ft, the football was 6 ft higher than the goal post when it went over.

Select the answer that correctly orders the set of numbers from greatest to least. 15% ,1/2 , 0.2 , 0.09.

15% in decimal form would be 0.15. 1/2 would be 0.50. So following that, if we were to place these in greatest to least form, then it would be: 0.50, 0.15, 0.09, 0.2. I hope I've ordered these correctly and that I've helped. Have a nice day.

Is 120 of 100 larger than 100

iragen [17]

$\text{Hey there!}$

$\text{Is 120\% of 100 larger than 100?}$

$\boxed{\text{The answer is: YES it is larger than 100}}\checkmark$

$\text{Reason}\downarrow\\\text{The word "of" means multiply in mathematical terms}\\\text{120\% = 1.2}\\\text{Re-ask yourself: Is 1.2}\times\text{100 larger than 100?}\\\bf{1.2\times100 = 120}\\\text{120 is LARGER/BIGGER than 100}$
