Atractor-trailer travels 205.296 miles in 3.12 hours. what is the speed at which the tractor-trailer is traveling? 62.05 miles per hour

65.8 miles per hour

Step-by-step explanation:

Distance traveled by a tractor-trailer=205.296 miles

Time taken to travel the distance=3.12 hours

We know that speed=

Dividing 205596 by 3120, we get 65.8

Thus Speed= 65.8 miles per hour

Therefore, the tractor-trailer is traveling with a speed of 65.8 miles per hour.

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
