F(t) = t2 + 4t − 14

y + 14 + 4 = ( t2 + 4t +4)

y + 18 = ( t + 2)^2

so the vertex of the parabola is ( -2 , -18)

<span>the axis of symmetry is y = -18</span>

Mai runs around a 400-meter track at a constant speed of 250 meters per minute. How many minutes does it take Mai to complete 4

Artyom0805 [142]

Answer:

$6.4$ minutes

Step-by-step explanation:

<u>Given information:</u>

- Track is 400m long

- Mai runs at a constant speed of 250 meters/minute

- - - - - -

To find how many minutes it takes for Mai to complete 4 laps, we need to find the total distance Mai is running for:

$400\times4=1600$ meters

To find how many minutes Mai is running for, we divide by the distance Mai travels per minute:

$1600\div250=6.4$ minutes

∴ Mai takes $6.4$ minutes to run 4 laps around the track.

Answer:

The Answer is: x = 29

Step-by-step explanation:

Put all of the angles equal to 360 degrees:

(5x - 8) + (3x + 4) + 89 + 51 = 360

Collect like terms and solve for x:

5x + 3x - 8 + 4 + 89 + 51 = 360

8x - 4 + 140 = 360

8x + 136 = 360

8x = 224

x = 224/8 = 28
