For a limited time, sammy’s gas station is offering a discount on the cost of gasoline when amounts greater than 5 gallons are purchased. the table below shows the cost for different amounts of gasoline.

which of these could be used to determine c, the cost for purchasing g gallons of gasoline with the discount?

a: c=2.65g
b: c=2.65g-12

C = 26.5g - 2

Step-by-step explanation:

We can plug in our given numbers for g and see if the C corresponds.

g = 7, C = 16.55

A) C = 2.65*7 --> C = 18.55

We know that C ≠ 18.55, so it should be B (I think you typed that one wrong, it is C = 2.65g - 2)

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
