PLEASE HELP AND HURRY PLEASE 5) Dan traveled to the town hall and back.
The trip there took five hours and the trip
back took two hours. What was Dan's
average speed on the trip there if he
averaged 50 km/h on the return trip?
A) 20 km/h B) 25 km/h
C) 10 km/h D) 17 km/h

a) 20

Step-by-step explanation:

2 hours at 50 km/h means she went 100 km

so 100/5= 20km/hr

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✌✌✌

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
