Question 7 (7 points)
Jackson is building a small rectangular basketball section in his backyard. The
length of the section will be 1.25 times the width of the section.
Part A (2 POINTS)
Create an equation to represent the area of the basketball section, A, in terms of
the width, w.
Part B (5 POINTS)
Jackson decides to make the area of the basketball section 245 square feet. What
are the dimensions, in feet, of the basketball section?

Step-by-step explanation:

A) The length is 1.25 times the width. The width is represented by w, so the length (L) is ...

  L = 1.25w

The area (A) is the product of length and width, so is ...

  A = Lw = (1.25w)(w)

  A = 1.25w²

__

B) The width of the section can be found by using the given area and solving for w:

  245 = 1.25w²

  196 = w² . . . . . . . . divide by 1.25

  14 = w . . . . . . . . . . take the square root

  L = 1.25·14 = 17.5 . . . . find the length

The dimensions of the section are 14 feet wide by 17.5 feet long.

what? that isnt a question

step-by-step explanation:

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
