It has a minimum value at x = 3 and f(x) = 4

Vertex form is

f(x) = a(x - 3)^2 + 4 where a is some constant to be found

From the graph when x = 5 f(x) = 15, so

15 = a * 2^2 + 4

a = 15-4/4 = 11/4

so our equation is f(x) = 11/4(x - 3)^2 + 4

Dmitry [639]

Step-by-step explanation:

5 divided by five-thirds can be written in the fractional form is as follows :

$\dfrac{5}{\dfrac{5}{3}}$

It can be also written as :

$\dfrac{5}{\dfrac{5}{3}}=5\times \dfrac{3}{5}\\\\=3$

He has done calculations as follows :

3 x 5/3=3/1 x 5/3 = 15/3 or 5

Miko was wrong in the first step where he multiplied 3 by (5/3). It should be 5 multiplied by (3/5). He has done multiplication incorrectly.

mylen [45]

Answer:

The average speed is:

$\var{v}=75\: miles/h$

Step-by-step explanation:

The average speed equation is given by:

$\var{v}=\frac{\Delta x}{\Delta t}$

Were:

Δx is the displacement (225 miles)
Δt is the change in time (3 hours)

Then we have:

$\var{v}=\frac{225}{3}$

$\var{v}=75\: miles/h$

I hope it helps you!
