Answer:

Usha is correct

Step-by-step explanation:

See attachment

Given

Dimension of the development

Height = \frac{1}{2}\ mile

Base = \frac{1}{2}\ mile

Dimension of a football field

Length = 100m

Width = 50m

First, we calculate the area of the development.

Because it is triangular in shape, the area is:

Area = \frac{1}{2} * Height * Base

Area = \frac{1}{2} * \frac{1}{2}mile * \frac{1}{2}mile

Convert mile to meter

Area = \frac{1}{2} * \frac{1}{2}* 1600m * \frac{1}{2} * 1600m

Area = \frac{1}{2} * 800m * 800m

Area = 400m * 800m

Area = 320000m^2

The area of 50 football pitch is then calculated as:

Area = 50 * Length * Width

Area = 50 * 100m * 50m

Area = 250000m^2

By comparison:

320000 > 250000

<em>Hence, Usha's thought is correct</em>

The answer is <span>A. f(t) = 100(0.25)t
</span>
This may be solved by inserting all points to your answer and sseeing if they work. Since <span>A. f(t) = 100(0.25)t fits with all points, this best represents the relationship between f(t) and t.
