Answer:

minimum

Step-by-step explanation:

Given a quadratic function in vertex form

f(x) = a(x - h)² + k

• If a > 0 then f(x) is a minimum

• If a < 0 then f(x) is a maximum

f(x) = 0.25(2x - 15)² + 150 ← is in vertex form

with a = 0.25 > 0

Thus f(x) has a minimum turning point

A walking path across a park is represented by the equation y=-3x - 3.A
kifflom [539]

Answer:

  y -6 = 1/3(x +3)   or   y = 1/3x +7

Step-by-step explanation:

The slope of the line describing the given path is the x-coefficient, -3. The slope of the perpendicular line will be the negative reciprocal of that:

  m = -1/(-3) = 1/3

The point-slope form of the equation for a line can be used to write the equation for the new path:

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

For m=1/3 and (h, k) = (-3, 6), the new path can be represented by ...

  y -6 = 1/3(x +3) . . . . point-slope form

  y = (1/3)x +7 . . . . . . slope-intercept form

What would the graph of y=x look like? name three ordered pairs that lie on the line.
ololo11 [35]

-- The graph looks like a line that passes through the origin,
and slopes up to the right at a 45-degree angle.

-- Point #1 on the line:
. . . . . Pick any number. 
. . . . . Write it down twice.
. . . . . Call the first one 'x'.  Call the second one 'y'.

-- Point #2 on the line:
. . . . . Pick any other number. 
. . . . . Write it down twice.
. . . . . Call the first one 'x'.  Call the second one 'y'.

-- Point #3 on the line:
. . . . . Pick any other number. 
. . . . . Write it down twice.
. . . . . Call the first one 'x'.  Call the second one 'y'.

Rinse and repeat, as many times as you like,
until the novelty wears off and you lose interest.
