Let
x-------> the number of points that the buffalo bills scored
y-------> the number of points that the Miami dolphins scored
we know that
-------> equation A
-------> equation B
Substitute equation B in equation A
![[24+2y]+y=66](https://tex.z-dn.net/?f=%5B24%2B2y%5D%2By%3D66)
<u>Find the value of x</u>
therefore
<u>the answer is</u>
the number of points that the buffalo bills scored was 
the number of points that the Miami dolphins scored was 
Answer:
46 years
Step-by-step explanation:
We have the logistic growth function 
and we want to find the time when the population will reach 20,000, to do it we just need to replace 
with 20,000 and solve for 
:
Divide both sides by 25,000
Multiply both sides by 
and divide them by 0.8
Subtract 1 from both sides
Divide both sides by 8.25
Take natural logarithm to both sides
Divide both sides by -0.076
≈ 46
We can conclude that the population will reach 20,000 after 46 years.

Answer:
an = 3n - 3
Step-by-step explanation:
The nth term of an arithmetic progression is expressed as;
an = a + (n-1)d
a is the first term
n is the number of terms
d is the common difference
a8 = a + (8-1)d
a8 = a + 7d = 21 ....1
a10 = a+9d = 27 ....2
Subtract 1 from 2
7d - 9d = 21 - 27
-2d = -6
d = -6/-2
d = 3
Since a + 7d = 21
a + 7(3) = 31
a + 21 = 21
a = 21 - 21
a = 0
Get the nth term
Recall that an = a + (n-1)d
an = 0 + (n-1)*3
an = 3n - 3
Hence the nth term of the sequence is 3n - 3
Answer:
21.98
Step-by-step explanation:
first you think about the equation for perimeter. P=d(pi)
then you multiply your radius by 2 and that is 7 so you multiply 7 by pi (3.14)
that is the number of feet. so then you multiply your number of feet by your cost per foot and you get 21.98
