Hello from MrBillDoesMath!
Discussion:
The slope of the tangent to the curve y = 4x^3 is given by the first derivative.
-----------------------------------
y' = 4 (3x^2) = 12x^2
At (-3,-108), the slope is 12x^2 = 12(-3)^2 = 12*9 = 108
-----------------------------------
-----------------------------------
y = mx + b
From the first part, m = 108 so y = 108x + b.
Substituting y = -108 when x = -3 gives
-108 = 108(-3) + b => add 3* 108 to both sides
-108 + 108(3) = b => as 3 -1 = 2
108*2 = b = 216
y = 108x + 216
-----------------------------------
Thank you,
MrB
Answer:
4/9
Step-by-step explanation:
(2/3)^2
(2/3) x (2/3)
2 x 2 is 4
3 x 3 is 9
4/9
Answer:
there is no y intercept. if there was it would be at the end of -3x
The best option is C. Provide multiple worksheets with pictures of the basic shapes for children to colour.
<h3>What does the learning process in children involve?</h3>
The process of learning has often been described to include all but not limited to the following:
- gaining new understanding,
- learning new behaviours,
- skills,
- values, attitudes, and
- preferences.
Children according to experts learn faster and easily remember what they see. Hence, providing multiple worksheets with pictures of the basic shapes for children to colour is the most cost-efficient strategy to support children in learning about shapes.

Answer:
1) B) a = 14
2)D) x = -11
3)B) x = 8
4)A) 250 = 3c-20
5)D)8
6)B), C), D)
8)A) 14 months
9)Sarah = 40 years
Sarah = 5/4 x Tanya
40 = 5/4 x Tanya's age
Therefore Tanya's age is 32 years old
Hope this helps you!
