Answer: y = x + 5

Step-by-step explanation:First, we need to determine the slope of the line. The slope can be found by using the formula: m=y2−y1x2−x1

Where m is the slope and (x1,y1) and (x2,y2) are the two points on the line.

Substituting the values from the points in the problem gives:

m=1−3−4−−2=1−3−4+2=−2−2=1

Now, we can use the point-slope formula to find an equation for the line. The point-slope formula states: (y−y1)=m(x−x1)

Where m is the slope and (x1y1) is a point the line passes through.

Substituting the slope we calculated and the values from the first point in the problem gives:

(y−3)=1(x−−2)

(y−3)=1(x+2)

We can now solve for y to put the equation in slope-intercept form:

y−3=x+2

y−3+3=x+2+3

y=x+5

The methods for calculating evapotranspiration from meteorological data require various climatological and physical parameters. Some of the data are measured directly in weather stations. Other parameters are related to commonly measured data and can be derived with the help of a direct or empirical relationship. This chapter discusses the source, measurement and computation of all data required for the calculation of the reference evapotranspiration by means of the FAO Penman-Monteith method. Different examples illustrate the various calculation procedures. Appropriate procedures for estimating missing data are also provided.

Meteorological data can be expressed in several units. Conversion factors between various units and standard S. I. units are given in Annex 1. Climatic parameters, calculated by means of the equations presented in this chapter are tabulated and displayed for different meteorological conditions in Annex 2. Only the standardized relationships are presented in this chapter. The background of certain relationships and more information about certain procedures are given in Annex 3. Annexes 4, 5 and 6 list procedures for the statistical analysis, assessment, correction and completion of partial or missing weather data.

Length "x" of the ramp = 11.70 ft

Step-by-step explanation:

Notice that the geometry to represent the ramp is a right angle triangle, for which we know one of its acute angles ( $20^o$ ), and the size of the side opposite to it (4 ft). Our unknown is the hypotenuse "x" of this right angle triangle, which is the actual ramp length we need to find.

For this, we use the the "sin" function of an angle in the triangle, which is defined as the quotient between the side opposite to the angle, divided by the hypotenuse, and then solve for the unknown "x" in the equation:

$sin(20^o)=\frac{opposite}{hypotenuse}\\ sin(20^o)=\frac{4}{x} \\x=\frac{4}{sin(20^o)} \\x=11.695\,\,ft$

Therefore the length of the ramp rounded to the nearest hundredth as requested is: 11.70 ft
