3 0

Step-by-step explanation:

To find a ratio, you have to divide a next terms with before terms.

A1 = 35/2

A2 = 7

ratio = A2 ÷ A1

ratio = 7 ÷ 35/2

ratio = 7 × 2/35

ratio = 14/35 = 0,4

Ratio = 0,4

What are the coordinates of the vertex of the function f(x) = x2 - 12x + 5?
FinnZ [79.3K]

Answer:

The vertex is the point (6,-31)

Step-by-step explanation:

we have

f(x)=x^2-12x+5

This is a vertical parabola open upward

The vertex represent a minimum

Convert to vertex form

Complete the square

f(x)=(x^2-12x+6^2)+5-6^2

f(x)=(x^2-12x+36)-31

Rewrite as perfect squares

f(x)=(x-6)^2-31 -----> equation in vertex form

therefore

The vertex is the point (6,-31)

The speed at which a certain computer can access the internet is 2 megabytes per second. How fast is this in megabytes per hour.
Ainat [17]
Converting\ units:\\\\ 2\frac{megabytes}{second}\\\\ 1second=\frac{1}{3600}h\\\\ 2\frac{megabytes}{second}*\frac{1}{\frac{1}{3600}}=2\frac{megabytes}{second}*\frac{3600}{1}=7200\frac{megabytes}{second}\\\\If\ 1second=\frac{1}{3600}\ you\ must\ multiply\ 2*\frac{1}{3600}\ to\ convert\ 1\ second\\ into\ hour.
