Answer:

Observation : No two such factors can be found !! Conclusion : Trinomial can not be factored. Equation at the end of step 1 : x2 - 7x - 14 = 0. Step 2 : Parabola, Finding the Vertex: 2.1 Find the Vertex of y = x2-7x-14

sdas [7]

It takes him 17 minutes to make each shoe.

<em>How to Solve: </em>

  1. take away the 30 min lunch break from the time becomes 11:45 to 4:00
  2. calculate the distance from 11:45 to 4:00 which is 4 hours and 15 minutes to complete each shoe.
  3. Convert the hours into 60 minutes each so 60*4= 240 now add the extra minutes 240+15= 255 minutes
  4. Now divide that bye 15 shoes 255/15= 17 minutes
  5. So it takes 17 minutes to make each shoe. :)

Suppose f(x) = x^2 and
SpyIntel [72]

Given:

The two functions are:

f(x)=x^2

g(x)=\left(\dfrac{1}{3}x\right)^2

To find:

The statement that best compares the graph of g(x) with the graph of f(x).

Solution:

The horizontal stretch is defined as:

g(x)=f(kx)            ...(i)

If 0, the function f(x) is horizontally stretched by factor \dfrac{1}{k}.

If k>1, the function f(x) is horizontally compressed by factor \dfrac{1}{k}.

We have,

f(x)=x^2

g(x)=\left(\dfrac{1}{3}x\right)^2

Using these functions, we get

g(x)=f\left(\dfrac{1}{3}x\right)         ...(ii)

On comparing (i) and (ii), we get

k=\dfrac{1}{3}

Since 0, the function f(x) is horizontally stretched by factor \dfrac{1}{\frac{1}{3}}=3.

Hence, the correct option is D.
