Answer: S
Step-by-step explanation:
w + ? - s = w
w + s - s = w
w = w
Answer:
= - 4 cm/s
Step-by-step explanation:
Let us revise the chain rule
If
= a and
= b, then
=
÷
= 
∵ y = x² + 1
- Use the differentiation to find 
∴
= 2x
∵ x = -1
- Substitute x by -1 in
∴
= 2(-1)
∴
= -2
∵
=
×
∵
= 2 cm/s
∴
= (-2) × (2)
∴
= - 4 cm/s
Because the triangle is an equilateral triangle, you know that all of the angles are equal to 60°. That means that you can use trigonometry to find the height, which would be sin(60) × 20 = 17.32.
Again, because it is an equilateral triangle, all sides are equal as well, meaning that the base is also 20cm. To find the area of the triangle, we must do (20 × 17.32)/2 = 173.2cm^2, which is the area.
I hope this helps!

Step-by-step explanation:
50-65 days
Pickling cucumbers should be ready to harvest between 50-65 days from planting and can be picked over the course of a several weeks. Growing pickling cucumber plants is just like growing other types of cucumber. They prefer a soil pH of 5.5, well-drained soil, and lots of nitrogen.
