If f(x)=x^2 is vertically stretched by a factor of 9 to g(x). What is the equation of g(x)?
AlexFokin [52]

Given:

The function is:

f(x)=x^2

This function is stretched by a factor of 9 to g(x).

To find:

The equation of function function g(x).

Solution:

The vertical stretch is defined as:

g(x)=kf(x)           ...(i)

If 0, then the function f(x) compressed vertically by factor k.

If k>1, then the function f(x) stretched vertically by factor k.

The given function f(x) is stretched by a factor of 9 to g(x).  So the value of k is 9.

Substituting k=9 in (i), we get

g(x)=9f(x)

g(x)=9x^2            [\because f(x)=x^2]

Therefore, the required function is g(x)=9x^2.

A ramp leading into a building makes a 15o angle with the ground. the end of the ramp is 10 feet from the base of the building.
Oksanka [162]
We are tasked to solved for the length of the ramp having an inclination of 15 degrees with the ground and 10 feet from the end of the ramp to the base of the building of the ground. Using trigonometric properties, we have a formula given an angle and the its opposite sides which is,
sin(Angle)=opposite/hypothenuse
hypothenuse would be the distance or the length of the ramp.
so we have,
sin(15)=10/hypothenuse
Cross-multiply, we have,
hypothenuse=10/sin(15)
using scientific calculator having a DEG mode,
hypothenuse=38.63703
Rounding of in nearest tenth we get,
hypothenuse=38.6 ft
Therefore, the ramp is 38.6 ft long
