Jelani is in a walking race at his school. In the first 20 seconds, he walks 60 meters. In the next 30 seconds, he walks 60 meters. In the
next 10 seconds, he walks 35 meters. In the last 40 seconds, he walks
80 meters.
a. Describe how Jelani's walking rate changes during the race.
b. What would a graph of Jelani's walking race look like?

SHOW WORK PLEASE FOR EACH NUMBER!

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌

i believe the answer is the polygon, heptagon.

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
