The graph of f(x)=cos(x) is transformed to a new function, g(x) , by stretching it horizontally by a factor of 4 and shifting it
SpyIntel [72]

The equation of the new function is g(x)= cos4 x+1

Explanation:

The Parent function is f(x)=cos x

We need to determine the new function g(x) using the transformation by stretching the f(x) horizontally by a factor of 4 and shifting it 1 unit up.

The function transformation formula is given by

f(x)=a \cos b(x-c)+d

Where a stretches the function vertically

b compresses or stretches it horizontally,

c shifts the function left or right

d shifts the function up or down

Since, it is given that the function stretches horizontally by a factor of 4 and shifting it 1 unit up.

Hence, b=4 and d=1

Substituting these values in the formula, we have,

g(x)=cos4x+1

Thus, the equation of the new function is g(x)= cos4 x+1

What is the greatest common factor of 18 and 45
lisov135 [29]
The prime factorization of 18 is: 2 x 3 x 3.
The prime factorization of 45 is: 3 x 3 x 5.
The prime factors and multiplicities 18 and 45 have in common are: 3 x 3.
3 x 3 is the gcf of 18 and 45.
gcf(18,45) = 9.

Arada [10]

Answer:

$0.07

Step-by-step explanation:

nails = 3.10/155 = 0.02/piece

screws = 7.65/85 = 0.09/piece

0.09 - 0.02 = 0.07
