Answer:
Count how many times the numerator goes over the denominator.
11/3 = 3 2/3
I believe they all have y-intersects at the origin. From the looks of it, D and E are the same expression. I'm not sure if that is a typo or not.
Answer:
25
+ 30z³ + 29z² + 12z + 4
Step-by-step explanation:
(5z² + 3z + 2)²
= (5z² + 3z + 2)(5z² + 3z + 2)
Each term in the second factor is multiplied by each term in the first factor, that is
5z²(5z² + 3z + 2) + 3z(5z² + 3z + 2) + 2(5z² + 3z + 2) ← distribute parenthesis
= 25 + 15z³ + 10z² + 15z³ + 9z² + 6z + 10z² + 6z + 4 ← collect like terms
= 25 + 30z³ + 29z² + 12z + 4
The pattern is that you are dividing by 3.
Therefore, to work out the next three numbers, you need to divide the last number by 3.
So you'd do:
1/9 ÷ 3 = 1/27
1/27 ÷ 3 = 1/81
1/81 ÷ 3 = 1/243
Therefore, the next three numbers are 1/27, 1/81, and 1/243.
The change in y (y being the height of the plant) over 4 weeks was 6 2/3 in.
The average rate of change of the plant's height is therefore
6 2/3 inches
------------------- = 1 2/3 inches/week on average.
4 weeks
The average rate of change of the plant growth per week was 1 2/3 inches. That would be the decrease per week.
