Answer:

l = 2.25 cm

Step-by-step explanation:

given l is inversely proportional to w² then the equation relating them is

l = \frac{k}{w^2} ← k is the constant of proportion

(i)

to find k use the condition w = 1.5 , l = 16 , then

16 = \frac{k}{1.5^2} = \frac{k}{2.25} ( multiply both sides by 2.25 )

36 = k

l = \frac{36}{w^2} ← equation of proportion

(ii)

when w = 4 , then

l = \frac{36}{4^2} = \frac{36}{16} = 2.25 cm

The table shows the record monthly high and low temperatures for a city in Alaska.
Neko [114]
A. The range is equal to the highest value minus the lowest value. Since the table given in part A is already in terms of range, then there is no need for a solution. The range of temperature for each month is as it is.

B. For this question, find the largest value which would represent the all-time high. That would be on February at 95°F. The lowest value would also represent the all-time low. That would be on July at 50°F.

C. The range of part B is just the difference of the all-time high and all-time low temperatures.
Range = 95°F - 50°F = 45°F
