Roni and allie are mowing the grass at the soccer field. roni has a riding lawn mower and can mow the field in 30 minutes. allie is pushing a lawn mower and can mow the field in 75 minutes.
if roni and allie work together to mow the field, what part of the field would roni mow?
a. about 0.52 of the field
b. about 0.64 of the field
c. about 0.71 of the field
d. about 0.87 of the field

C. about 0.71 of the field

Step-by-step explanation:

Since,  Roni can mow the field in 30 minutes.

Thus, the work done by Roni in one day = 1/30

And,  Allie can mow the field in 75 minutes.

Thus, the work done by Allie in one day = 1/75

⇒ The total work done by Roni and Allie in one day when they worked simultaneously,

=

=

=

⇒ Option C is correct.

answer: i think it is (1,-2)

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.

hope i !
