dybincka [34]

<u><em>The </em></u><u><em>number of trains</em></u><u><em> that arrived Dubai metro station on time is; 272 trains. </em></u>

<u><em /></u>

  • We are told that 320 trains arrived the Dubai metro station in a week.

  • Now, we are told that 5% got there early and 15% got there late.

This means, the percentage that got there on time is;

100% - % of trains that got there late.

  • Therefore, percentage of trains that got there on time is;

100% - 15% = 85%

  • Since 85% of the trains got there on time, then number of trains that got there on time is;

85% × 320 = 272

  • Therefore, we can conclude that 272 trains arrived on time.

Can anyone help me solve all of this? Please help

They are all pretty easy all you do is multiply the cost by the amount of things you buy. For example number 4 your variables are cost (c) and songs (s). Your equation is c•s so $0.99 • s. 50 songs would be .99 • 50 which is $49.50

Write the equation of the following graph in vertex form.
Marat540 [252]

Answer:

Correct choice is 2. f(x)=0.4(x+2)(x-5)

Step-by-step explanation:

We have been given a graph of the quadratic function. Now we need to use that graph to find the equation of the graph in vertex form. By the way given choices written in intercept form so to be accurate we are going to find the equation in intercept form.

from graph we see that x-intercepts are at 5 and -2.

we know that if x=a is x-intercept then (x-a) must be factor.

So (x+2)(x-5) is the factor.

when leading coefficient is positive then graph opens upward.

so that means leading coefficient is 0.4

Hence correct choice is 2. f(x)=0.4(x+2)(x-5)
