Sean is running a 100 m dash. When the starter’s pistol fires, he leaves the starting block and continues speeding up until 6 s into the race, when he reaches his top speed of 11 m/s. He holds this speed for 2 s; then his speed slows to 10 m/s by the time he crosses the finish line 11 s after he started the race. PREPARE A GRAPH OF THIS DTA
• Time (the constant, in seconds on the X axis)
• Velocity (the variable, in m/sec) on the Y axis)
USE THE DATA FROM THE GRAPH TO ANSWER THE FOLLOWING
a. What was Sean’s average acceleration during the first 6 s of the race?
b. What was Sean’s average acceleration from 6 to 8 s into the race?
c. What was Sean’s average velocity for the whole race?
d. What was Sean’s average acceleration from 8 to 11 s into the race?

dude thats to long figure it

step-by-step explanation:

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
