Answer:
c. 5
Step-by-step explanation:
Counting the check digit, there are 12 digits, so this is a GTIN-12 code. Alternate digits are multiplied by 3 and the result summed with the sum of the other digits. The check digit is the amount required to make this sum be a multiple of 10.
(4 +9 +0 +0 +7 +2)·3 +(8 +0 +0 +3 +8) = 66+19 = 85
The check digit is 5, the number that must be added to this to make the total 90, a multiple of 10.
Answer:
y =
x+1
Step-by-step explanation:
To find a right angle we need to find the perpendicular line. The trick here is to do the flip of your slope and since there is no "that passes through the point (#, #) you're done after that. So the answer is
y =
x+1

Answer:
![(1.3t^3 + 0.4t^2 - 24t) + (8 - 18t + 0.6t^2) = 1.3t^3 + t^2 -42t + 8](https://tex.z-dn.net/?f=%281.3t%5E3%20%2B%200.4t%5E2%20-%2024t%29%20%2B%20%288%20-%2018t%20%2B%200.6t%5E2%29%20%3D%201.3t%5E3%20%2B%20t%5E2%20-42t%20%20%2B%208)

Solve
We have:
![(1.3t^3 + 0.4t^2 - 24t) + (8 - 18t + 0.6t^2)](https://tex.z-dn.net/?f=%281.3t%5E3%20%2B%200.4t%5E2%20-%2024t%29%20%2B%20%288%20-%2018t%20%2B%200.6t%5E2%29)
Collect like terms
![1.3t^3 + 0.6t^2 + 0.4t^2 - 24t- 18t + 8](https://tex.z-dn.net/?f=1.3t%5E3%20%2B%200.6t%5E2%20%2B%200.4t%5E2%20-%2024t-%2018t%20%20%2B%208)
![1.3t^3 + t^2 -42t + 8](https://tex.z-dn.net/?f=1.3t%5E3%20%2B%20t%5E2%20-42t%20%20%2B%208)
So:
![(1.3t^3 + 0.4t^2 - 24t) + (8 - 18t + 0.6t^2) = 1.3t^3 + t^2 -42t + 8](https://tex.z-dn.net/?f=%281.3t%5E3%20%2B%200.4t%5E2%20-%2024t%29%20%2B%20%288%20-%2018t%20%2B%200.6t%5E2%29%20%3D%201.3t%5E3%20%2B%20t%5E2%20-42t%20%20%2B%208)
