Answer:
1: C. $3,474.38
2: B. $44.10
C: C. $570
Step-by-step explanation:
1.
4250 - (4250 x 0.25)
3187.50
3187.50 + (3187.50 x 0.09)
3474.375 which rounds up to
$3,474.38
2.
52 - (52 x 0.2)
41.6
41.6 + (41.6 x 0.06)
44.096 which rounds up to
44.10
3.
500 + (500 x 0.2)
600
600 - (600 x 0.05)
570
The image of p is (-1, 1)
Because the rule for 270 counterclockwise is (y,-x)
The correct answer is: [C]: " (0, 24) " .

Given the quadratic function:
___________________________________________________________
→ " y = (x <span>− 8) (x + 3) " ; </span>← Note: Replace the "f(x)" with: "y" ;
→ Find the "y-intercept".
___________________________________________________________
→ Note: The "y-intercept" is the coordinate of the point(s) of the graph of the equation at which the graph crosses the "x-axis" when "x = 0" .
→ So; we set plug in "0" for "x" into our equation; and solve for "y" ;
→ " y = (x − 8) (x + 3) " ;
→ y = (0 − 8) (0 + 3) ;
→ y = (-8) * (3) ;
→ y = - 24 ;
___________________________________________________________
So, the "y -intercept" of the <em><u>given</u></em> quadratic function is:
the point at which: "x = 0 ; y = -24 " ;
→ that is; the point the coordinates: " (0, - 24) " ;
___________________________________________________________
→ which is: Answer choice: [C]: " (0, - 24) " .

The cost of the roll = 125 * 45 = 5625 cents
5625 / 100 = 56.25 $
