Consider the following qaudratic function .f(x)=9x^2

Question:

Consider the following quadratic function. f(x) = −9x^2 + 16x − 13.

Identify the vertex

Step-by-step explanation:

Given

Identify the vertex

The vertex of an equation is represented as:

i.e.

In

becomes

Substitute 8/9 for x in

Take LCM

Hence, the vertex is:

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
