Answer:

see explanation

Step-by-step explanation:

The axis of symmetry is a vertical line with equation x = c

Where c is the x- coordinate of the turning point, that is

x = - 1

The coordinates of the vertex, the turning point are (- 1, - 6 )

The y- intercept is where the graph crosses the y- axis , that is

y- intercept = - 3

James and Cameron are watching a film. They pause it with one fifth left to watch. What is the ratio of how much they have watch

goldenfox [79]

Answer:

The ratio of how much they have watched to how much they have left to see is 4 : 1.

Step-by-step explanation:

Consider that the total duration of the film is, 1.

It is provided that James and Cameron paused when there is one-fifth left to watch.

That is, they have already watched, $1-\frac{1}{5}=\frac{4}{5}$ th of the film.

Compute the ratio of how much they have watched to how much they have left to see as follows:

$\frac{\text{Duration Watched}}{\text{Duration Left}}=\frac{4/5}{1/5}=\frac{4}{1}=4:1$

Thus, the ratio of how much they have watched to how much they have left to see is 4 : 1.

So 15 flowers she can buy
