Answer:
Kindly check explanation
Step-by-step explanation:
Given the question:
Find the error in the student's calculation. 2 cubed (2 minus 4) + 5 (3 minus 8). 2 cubed (negative 2) + 5 (5). 8 (negative 2) + 25. Negative 16 + 25. 9.
The student's error occurred here :
2 cubed (negative 2) + 5 (5)
(3 - 8) will give - 5 and not 5 as Witten by the student. The correct working is stated below :
2³(2 - 4) + 5(3 - 8)
Step 1:
8(-2) + 5(-5)
Step 2:
-16 + - 25
Step 3:
-41
- Vertex form:
, with (h,k) as the vertex.
For this, we will be using vertex form. Firstly, plug the vertex into the vertex form equation:
Next, we need to solve for a. Plug in (-2,4) into the x and y coordinates to solve for a as such:
Putting our equation together,<u> it's 
</u>

- Standard form:
Converting to standard form as such:
9514 1404 393
Answer:
- 0.404 . . . cm/day
- the average growth per day in cm
Step-by-step explanation:
The slope is the x-coefficient in the equation, 0.404.
The slope is the rate of change of the dependent variable (height) with respect to the independent variable (number of days). In this case, it is the average increase in the plant's height each day, in cm.
Answer: 1, 8, 64, 512
Step-by-step explanation:
1^3 = 1 * 1 * 1 = 1
2^3 = 2 * 2 * 2 = 8
4^3 = 4 * 4 * 4 = 64
8^3 = 8 * 8 * 8 = 512
