About how much difference in average leaf width would you find in two forests whose average annual rainfalls are near 1500 mm bu
goblinko [34]

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!!!

Alexa worked 30 hours last week and earned $450. Her pay has now been increased by 20%. Which equation describes her new rate of
vesna_86 [32]

Answer:

p=18h

or

p=\dfrac{450}{30}\cdot 1.2\cdot h

Step-by-step explanation:

If Alexa worked 30 hours last week and earned $450, then her hourly payment is

\dfrac{\$450}{30}=\$15.

Her payment has now been increased by 20%, so her hourly payment becomes

\$15\cdot 1.2=\$18.

If she worked h hours, then she earned \$18h. If her new payment is p, then

p=18h

or

p=\dfrac{450}{30}\cdot 1.2\cdot h.
