3+5x=38
-3 on both sides
5x=35
divide by 5 on both sides

We have that
$y=- x^{2} +36$

we know that
Is the equation of a vertical parabola open down
so
the vertex is a maximum

step 1
convert the equation of the parabola in the vertex form
$y=- x^{2} +36 \\ y-36=- x^{2}$

the vertex (h,k) is the point (0,36)

Part a) The point on the graph where the height of the tunnel is a maximum is (0,36)

Part b) The points on the graph where the height of the tunnel is zero feet is when y=0
so
for y=0
$- x^{2} +36=0 \\ x^{2} =36 \\ x= (+/-) 6$

the points are (-6,0) and (6,0)

see the attached figure

Mrs. Elizondo runs around a 400-meter track at a constant speed of 250 meter per minute. How many minutes does it take Mrs. Eliz

anastassius [24]

Answer: See explanation

Step-by-step explanation:

From the information, we are told that Mrs. Elizondo runs around a 400-meter track. If she runs 4 laps, the total meters will be:

= 400 × 4

= 1600 meters

Since she uses a constant speed of 250 meter per minute. The number if minutes taken to complete the 4 laps will be gotten by dividing 1600 by 250. This will be:

= 1600 / 250

= 6.4 minutes

= 6 minutes + (0.4 × 60 seconds).

= 6 minutes 24 seconds
