For a radius of 7 ft, the area is

... A = π·(7 ft)² = 49π ft² ≈ 154 ft²

the basket balls height when bounced can vary. depending on the strength of ball being thrown to the ground can make the ball bounce even higher. So for an example, if you applied full force from a average weighted male adult. The basket ball will bounce a decent height. But, of course will for sure not be as high as to the first bounce.

hope this helps

What is the nth term rule of the quadratic sequence below? 7, 14, 23, 34, 47, 62, 79
Julli [10]

Answer:

Tn = Tn-1 + 2(n-1) + 5

Kindly note that Tn-1 means T subscript n-1

Step-by-step explanation:

Here, we want an expression for the nth term.

First term is 7

Then first common difference is 7

second common difference is 7 + 2

Third common difference is 9 + 2

So within the common differences, the nth term is 7 + (n-1) 2

Now, the nth term of the series would be;

Tn = Tn-1 + 7 + 2(n-1)

Tn = Tn-1 + 7 + 2n -2

Tn = Tn-1 + 2n + 5

Now there is a fix to this,

n for the term is not the same n for the common difference.

the 7th term works with the 6th common. difference, while the 8th term work for the 7th common difference.

So we might need to rewrite the final expression as follows;

Tn = Tn-1 + 2(n-1) + 5
