Which describes the pilot’s distance in section i? zero constant decreasing increasing
The pilot's distance is increasing.
In the graph, we can see distance on y axis and time on x axis. It is clearly visible that at 2 minutes, the distance covered is 0.4 miles. Further, at 4 minutes, the distance covered increases to 0.8 miles. At 6 minutes, the distance covered again increases by 0.4 miles and is 1.2 miles. At 8 minutes, the distance covered in 1.6 miles, which again increases by 0.4.
Now, it is evident that distance is increasing.
We can further calculate the speed using given information -
Speed = distance/time
Total distance = 1.6 - 0.0
Total distance = 1.6 miles
Total time = 8 - 0
Total time = 8 minutes
Speed = 1.6/8
Speed = 0.2 miles per minute.
Hence, the distance of pilot is increasing at constant rate or speed of 0.2 miles per minute.

Write an equation of each line in point-slope form.
(0,0) and (-4,-5)
The equation of the line in point-slope form, which passes through the pair of points located at (0 , 0) and (-4 , -5), is y + 5 = 5/4(x + 4).
The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.
The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).
Getting the slope of the two points: (0 , 0) and (-4 , -5)
m = (y2 - y1)/(x2 - x1)
m = (-5 - 0)/(-4 - 0)
m = -5/-4
m = 5/4
Using the point slope form, plug in the values of the slope and Point A to set up the equation.
(y - y1) = m(x - x1)
where m = 5/4 and (x1 , y1) = (-4 , -5)
(y - -5) = 5/4(x - -4)

An airplane on a long-distance flight flew the first 1295 miles of it's journey on 3 hours and 33 minutes. After that, the wind changed, and it took the plane 1 hour and 47 minutes to cover the remaining 738 miles. What was the plane's average speed during the flight?
Round to the nearest tenth
The plane's average speed during the flight is 381.43 miles per hour.
What is the average speed?The average speed is the quotient of the total distance covered during the flight divided by the total time used.
The Average Speed is the scalar quantity that shows the rate of change in displacement from one point to another.
Data and Calculations:The distance for the first miles = 1,295 miles
The time it took the plane to cover the distance = 3 hours 33 minutes
The distance for the last lap = 738 miles
The time it took the plane to cover the last distance = 1 hour 47 minutes
The total distance covered for the journey = 2,033 miles (1,295 + 738)
The total time for the journey = 5 hours 20 minutes or 5.33 hours
Average Speed = 2,033/5.33
= 381.43 miles per hour
Thus, the plane's average speed during the flight is 381.43 miles per hour.

Make a conjecture about the measure of an exterior angle and the sum of the measures of its nonadjacent interior angles.
Here we can conjecture that :
The measure of an exterior angle is equal to the sum of measures of its nonadjacent interior angles.
What is interior and exterior angle ?The exterior angle of any polygon is defined as the angle which is at the outside boundaries of that polygon. whereas, the interior angle is defined as the angle which is inside the polygon. In the other words if the polygon has the point within the angle it is in the interior of the angle , but if the point is outside then is it said to be in the exterior of the angle.
What is Non adjacent interior angle ?Non adjacent angles are those angles which are not adjacent to each other. The non adjacent angles follow one of the properties which are listed below:
They do not share a common vertex or common side.They can share a side, but not share the common vertex.They share a common vertex, but not share the common side.In the given question,
taking a example say a triangle ABC with ∠A=64, ∠B = 45 and an external angle x to the side AC.
as sum of angles equal to 180
thus, ∠A + ∠B + ∠C = 180
64 + 45 + ∠C = 180
∠C = 180-109 = 71
now as x is external to ∠C,
therefore x = 180 - ∠C = 180 - 71
x = 109 = ∠A + ∠B
Hence we can make the conjecture that, the measure of an exterior angle is equal to the sum of measures of its nonadjacent interior angles.

Suppose the flight leaves 30 minutes early. What function represents this transformation?
The function that represents the Transformation of the graph is F(X+1/2).
Different non-vertical lines have different slopes and/or y-intercepts. They are graphs of various linear functions. If there are two such lines, one can be considered a transformation of the other. There is a group of functions called the family, each function being a transformation of a special function called a parent. Linear functions form a series of functions. All linear functions are transformations of the function y = x. The function y = x is an upper linear function. Each family role is a transformation of a parent's role. The conversion type is translation. A translation moves the graph of the parent function horizontally, vertically, or both without changing shape or orientation. So, the function that represents this transformation is F(X+1/2).
