Which point is on the graph of f(x)=2x= 2.5%?
katovenus [111]

Answer: The parabola has its concavity downwards, so we need a function in the model:

With a negative value of 'a'

The vertex is (0,0), so we have that:

The x-coordinate of the vertex is given by the equation:

So we have a function in the model:

With a < 0

The only option with this format is B:

PLEASE HELP ME ! Convert the following description to a proper scale ratio:
galina1969 [7]

Answer:

  1 : 400,000

Step-by-step explanation:

A map scale is usually represented as a unit fraction, one with 1 in the numerator. It has no units, which is to say that it is the ratio of same units.

It can be found by dividing the map dimension by the ground dimension when both are expressed in the same units.

  (8.4 cm) / (33.6 km) = (8.4×10^-2 m) / (33.6×10^3 m) = (8.4/33.6)×10^-5

  = 0.25×10^-5 = 1/400,000

__

<em>Additional comment</em>

Map scales are often expressed using the colon for the ratio unit separator:

  1 : 400,000
