Answer:
b
Step-by-step explanation:
The function represented by the graph is
y = { x² + 6 , x < 3
-x + 6 , x ≥ 3}
What is a function ?In mathematics, a function is an expression, rule, or law that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.
According to the graph
When x < 3 then y = + 6
and, at x = 3 we get an open interval.
So, y = x² + 6 is valid for x < 3 not at x =3.
Also , y = -x + 6 is valid for x ≥ 3 and we get a close interval.
Thus, the function represented by the graph is
y = { x² + 6 , x < 3
-x + 6 , x ≥ 3}

A rectangle has dimensions 2x – 12 by 3x + 9 and area 60 cm². What are the actual
dimensions of the rectangle?
Answer:
2 x 30 cm

(2x-12)(3x+9) = 60
6x^2 -18x-168=0
use quadratic fromula to find x = 7 or -4 (throw out)
the sides then become ( using 7)

The diameter of the cone is 6 inches. It’s height is 4 inches. What is its slant height?
Answer:
5 inches
Step-by-step explanation:
As the height is perpendicular to the base, the radius and the height form a right angle, creating a right triangle where the slant height is the hypotenuse, thus:
[tex](height)^2+(radius)^2=(slant\:height)^2[/tex]
[tex]4^2+(6/2)^2=(slant\:height)^2[/tex]
[tex]16+9=(slant\:height)^2[/tex]
[tex]25=(slant\: height)^2[/tex]
[tex]5=slant\: height[/tex]
In conclusion, the slant height of the cone is 5 inches. See below for a visual.
