5 minutes would be 290 and 8 minutes would be 464.
Answer:
![d(n) = d(1) \times r^{(n - 1)}](https://tex.z-dn.net/?f=d%28n%29%20%3D%20d%281%29%20%5Ctimes%20r%5E%7B%28n%20-%201%29%7D)
Step-by-step explanation:
For a geometric sequence, we have to find the explicit formula for the nth term.
If d(1) is the first term of a geometric sequence with common ratio r, then the sequence is given by :
d(1), d(1) × r, d(1) × r², d(1) × r³, .......
Therefore, the nth term of the sequence is given by
and this id the explicit formula. (Answer)
Answer:

Answer:
3/4
Step-by-step explanation:
If it helps you can find a visual or draw it.
The area of a rectangle is its <u>length x width</u>.
The perimeter of a rectangle is its <u>length + length + width + width</u>.
Let's have l stand for length and w for width. A will stand for area and P for perimeter. This gives us:
399 = l x w
80 = 2l + 2w We can divide both sides of this equation by 2 to get <u>40 = l + w</u>.
Now we need to find two numbers whose sum is 40 and product is 399.
Fitting some random numbers in gives us the numbers 19 and 21 for the length and width.
