Answer: The product of 40 and distance to the finish line is represented as 40d.
Step-by-step explanation:
Let the distance to the finish line be 'd'.
We need to translate the product of 40 and d in mathematical term.
Product is an expression in which factors needs to be multiplied.
So, product of 40 and d means 40 times d.
Mathematical, it is expressed as
Hence, the product of 40 and distance to the finish line is represented as 40d.

Answer:
6 ft
Step-by-step explanation:
As we know that, the arch meet the ground are the value of x when y = 0
y=−0.9(x+3)(x−3)
<=> 0 = −0.9(x+3)(x−3)
<=> x=3 or x=-3
So we have 2 coordinates: (3, 0) and (-3,0) and the distance between them is:
3 -(-3) = 6
=> The width of the arch at ground level is 6 ft
