Timmy's Taxi Service charges a flat fee of $1.50, plus an additional fee for each mile of travel. A 5 mile trip costs $11.50 and a 9 mile trip costs $19.50. Which statement is true about the relationship between miles and cost?

Group of answer choices

The relationship is linear because it increases at a constant rate of change of $2 per mile.

The relationship is linear because it increases at a constant rate of $8 per mile.

The relationship is exponential because it increases at a changing rate of $2 per mile.

The relationship is exponential because it increases at a changing rate of $8 per mile.

depends on how many days you are talking about

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
