Answer:
A) 25.872
Step-by-step explanation:
A tip when multiplying numbers that are decimals, make the numbers whole numbers without decimals:
862.4 * 10 = 8624
0.03 * 100 = 3
8624 * 3 = 25,872
Then divide by the amount you multiplied the numbers by:
25,872 ÷(100 * 10) = 25.872
So your answer is A) 25.872

Answer:
Step-by-step explanation:
i) 1
ii) see attached
iii) as x goes from 0 to 2, y decreases parabolically from 1 to an acme at -3
iv) y = (x - 2)² - 3
v) -3 < t < 1
if t < -3 no intersection occurs between y = t and y = (x - 2)² - 3
if t = -3, y = t intersects the curve at only one point, (2, -3)
if -3 < t < 1 there exist two intersecting points with positive x values
if t = 1 there exist only one positive x value intersection as the other is at (0, 1) and 0 is neither positive nor negative.
if t > 1 there is one positive x value intersection and one negative x value intersection.
