Find the complete table in attached file.

Step-by-step explanation:

Find the Incomplete table in attached file

Given:

A car travels 55 miles per hour for 2 hours.

So the speed of the car 55 miles per hour is constant for 2 hours.

Using speed  formula.

Second row.

From the second row of the table and speed is constant , so we need to find only distance.

Third row.

From the third row of the table and speed is constant , so we need to find only distance.

Fourth row.

From the fourth row of the table and speed is constant , so we need to find time.

Therefore we complete the table from the above calculation.

step-by-step explanation:

i need to answer questions so i dont know but i think its the first one because it goes up but a consent rate

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."
