5. Identify the constant of proportionality from the table below. Constant of proportionality: 6. Identify the constant of proportionality from the graph below. Constant of proportionality: Learning Target 26​-I can create an equation to model a proportional relationship. 7. A student spends the same amount each week for bus fare. In 5 weeks, he spends $115. Write an equation to model this relationship. Use ​x​ to represent the number of weeks and ​y​ to represent the total cost. 8. Write an equation to model the proportional relationship from the graph. Time (h) 25 50 75 100 Earnings ($) 160 320 480 640

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

step-by-step explanation:

no solution.

d 600 because 15*10*2=300

300+300=600

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
