The number f of miles a helicopter is from its destination x minutes after takeoff is given by f (x)=40-2x. The number f of miles a commercial jet is from its destination x minutes after takeoff is shown in the graph below.

The total distance and time taken for each flight are illustrations of intercepts.

We have:

minutes

miles

Helicopter

Set f(x) to 0, to calculate the x-intercept

Collect like terms

Divide by 2

Set x to 0, to calculate the y intercept

This means that, the helicopter traveled 40 miles in 20 minutes

Commercial Jet

From the graph, the intercepts are:

--- the x-intercept

--- the y-intercept

This means that, the commercial jet traveled 500 miles in 100 minutes

Step-by-step explanation:

Function 'f' represents the number of miles (y-values) covered by the helicopter in 'x' (x-values) minutes.

f(x) = 40 - 2x

For x = 0,

f(x) = 40 miles

For f(x) = 0,

0 = 40 - 2x

x = 20 minutes

This shows that helicopter traveled 40 miles in 20 minutes.

Similarly, given graph shows distance covered by the jet on y-axis and duration of flight on x-axis.

For x = 0,

f(x) = 500 miles

For f(x) = 0,

x = 100 minutes

Commercial jet traveled 500 miles in 100 minutes.

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
