A local car wash is open 8 hours each day. It uses 1/3 of a container of wax for each car. The car wash waxes an average of 8 1/
sweet-ann [11.9K]

Answer:

22.67 containers.

Step-by-step explanation:

The number of cars washed is the average by the total hours worked:

C_{total}=\bar xt,\bar x=8.5,t=8\\\\C_{total}=8.5\times 8=68

Given that each car uses 1/3 tin of wax, the total containers is calculated as:

Containers=\bar x_c n,n=68,\bar x_c=\frac{1}{3}\\\\=\frac{1}{3}\times 68\\\\=22.67

Hence, the car wash uses 22.67 containers of wax per day.

Which of the following is the general term for the sequence? -a, a^2, -a^3, a^4,...
Elis [28]

Answer:

The answer would be -a(-a)^{n-1}.

Step-by-step explanation:

We can simply substitute the terms into this equation. Checking the 1st term, -a(-a)^{1-1} = -a(-a)^{0} = -a(1) = -a. Moving on to the second term, we see -a(-a)^{2-1} = -a(-a)^{1} = -a(-a) = a^{2}. And so on and so forth. We can see how the answer fluctuates between negative and positive, while gaining one more exponent every term, which fits with the sequence given. Therefore, the answer would be -a(-a)^{n-1}.

Hope this helped!
