Answer:

Step-by-step explanation:

let wind velocity=x

speed of plane=y

(x+y)*4=808

x+y=808/4=202   ...(1)

(y-x)*4=488

y-x=122 ...(2)

add (1) and (2)

2y=202+122=324

y=324/2=162

from (1)

x+162=202

x=202-162=40

wind velocity=40 m/hr

speed of plane=162 m/hr

Does the quadratic have a maximum or minimum
STALIN [3.7K]

Answer:

B)max/ opens down

Step-by-step explanation:

Parabola equation:

The equation of a parabola has the following format:

y = ax^2 + bx + c

If a > 0, that is, x² is multiplied by a positive number, the function has a minimum value and the parabola opens up.

If a < 0, that is, x² is multiplied by a negative number, the function has a maximum value and the parabola opens down.

In this question:

y = -x^2 - 2x + 3

From the graph, we already see that it opens down and has a max, and analitically, since a = -1 < 0, this is confirmed. The correct answer is given by option b.
