Answer:
Average = 96
Step-by-step explanation:
Average = sum of terms/ number of terms
sum of terms = number of burgers sold
number of terms = number of visitors
d = number of days since Monday which is 7
burgers sold = 200d^3 + 542d^2 + 179d + 1605 substituting d with 7
burgers sold = 200(7)³ +542(7)² + 179(7) +1605
burgers sold =68600 + 26558 + 1253 + 1605
burgers sold =98016
number of visitors= 100d + 321
number of visitors= 100(7) + 321
number of visitors= 700+321
number of visitors= 1021
Average = 98016/1021
Average = 96
Answer:
b = 7, c = -44
Step-by-step explanation:
If the quadratic equation has the solutions -11 and 4, the two factors are:

Since when we use the zero factor property we get
x+11=0 ⇒ x= -11
x-4=0 ⇒ x=4
Thus, we have used the zero factor property in reverse to find the factorization of the quadratic equation.
Now we develop the multiplications between parenthesis:

So b is the number that accompanies the x: b = 7
and c is the independent number: c = -44
The number of months that it will take the latest model's battery life to reach 1,008.9 minutes is; 8 months
<h3>How to solve geometric progression?</h3>
Each month, there is an increase by a factor of 0.06 of the previous months model.
From geometric sequence formula of aₙ = ar^(n - 1),
where;
a is first term
r is common ratio
aₙ is nth term
we have;
1,008.9 = 671 * 1.06^(n - 1)
1008.9/671 = 1.06^(n - 1)
In 1.504 = (n - 1) In 1.06
0.408 = (n - 1) * 0.058
n - 1 = 0.408/0.058
n = 7.03 + 1
n ≈ 8 months
