Answer:
4.80 mm to 2 d.p
Step-by-step explanation:
w = f(r)
f'(r) = (dw/dr) = (0.0218 mm/mm)
So, for a small difference in rainfall of 220 mm, what is the corresponding small difference in width of leaves in the two forests given.
One definition of a derivative or a rate of change is that it is the ratio of very small differences in the dependent variable to very small differences in the independent variable.
Mathematically,
(dw/dr) = (Δw/Δr) for very small Δw and Δr.
0.0218 = (Δw/220)
Δw = 0.0218 × 220 = 4.796 mm = 4.80 mm to 2 d.p
Hope this Helps!!!
Answer:
$4.21
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 4.9 × 14/100
Discount = 4.9 x 0.14
You save = $0.69
Final Price = Original Price - Discount
Final Price = 4.9 - 0.686
Final Price = $4.21
The formula is (degree)x(pi÷180)
36 x pi ÷ 180
0.63 rad
