,Maura run faster.

Step-by-step explanation:

Given  : Maura runs 5 miles in 1.25 hours. Ava runs 3 miles in 50 minutes, or 0.83 hour.

To find : Who runs faster.

Solution : We have given

Maura runs in 1.25 hours = 5 miles.

Maura runs in 1 hours =   miles.

Maura runs in 1 hours =   miles.

                                    = 4 miles.

Ava runs in 0.83 hour=  3 miles.

Ava runs in  1 hour=  3 * 0.83 miles.

                               = 2.49 miles.

So, Maura run faster.

Therefore,Maura run faster.

f(-1) = 0

Step-by-step explanation:

Given information

f (-1) or x = -1

Given function

f(x) = 3x² + 2x - 1

Substitute values into the expression

f(-1) = 3 (-1)² + 2 (-1) - 1

Simplify the exponents

f(-1) = 3 (1) + 2 (-1) - 1

Simplify by multiplication

f(-1) = 3 - 2 - 1

Simplify by subtraction

f(-1) = 1 - 1

f(-1) =
