Answer:
The height of the projection will be (x - 5) feet.
Step-by-step explanation:
A projector displays an image on a wall. The area (in square feet) of the rectangular projection can be represented by (x² - 8x + 15).
Now to get the width and the height of the rectangular projection we have to factorize the expression (x² - 8x + 15).
Here, (x² - 8x + 15)
= x² - 3x - 5x + 15
= (x- 3)(x - 5)
Now, if the height of the projection is less than its width then, the height of the projection will be (x - 5) feet. (Answer)
The factors of the expression are :
y = (x - 2)(x - 6)
The x-intercepts are found by putting y = 0.
Therefore the x-intercepts are at (2, 0) and (6, 0).
The x value of the vertex is (2 + 6)/2 = 4.
f(4) = 16 -32 +12 = -4.
The coordinates of the vertex are (4, -4).
