A 3-mi cab ride costs $3.00. A 6-mi cab ride costs $4.80. Find a linear equation that models cost c as a function of distance d. c = 1.00d + 1.80 d = 0.60c + 1.80 c = 0.60d + 1.20 c = 0.80d + 1.20

c=0.6d+1.2

Step-by-step explanation:

Let c the cost and d the distance. The linear equation has the form

c=md+b

the slope m can be computed by means of the given points:

(d1,c1)=(3,3)

(d2,c2)=(6,4.8)

where

hence

Now, we must find the y-intercept "b" in the equation c=0.6d+b, by using the point (3,3), that is

3=0.6(3)+b

3=1.8+b

b=3-1.8

b=1.2

Finally, the answer is

c=0.6d+1.2

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
