Note: a² - b² = (a-b)(a+b)
9x² - 16y² = (3x)² - (4y)² = (3x - 4y)(3x + 4y)
Answer:
Step-by-step explanation:
If -x,y that would be Quadrant 2
Hey there! :)
Answer:
f(-2) = -148.
Step-by-step explanation:
To calculate f(-2), simplify substitute -2 for x in the equation. Therefore:
f(x) = 4x³ -12x² + 40x + 12
Becomes:
f(-2) = 4(-2)³ - 12(-2)² + 40(-2) + 12
Simplify:
f(-2) = 4(-8) - 12(4) - 80 + 12
f(-2) = -32 - 48 -80 + 12
Finally, you get:
f(-2) = -148.
Answer:
Options (A), (C), (D) and (E).
Step-by-step explanation:
There are two types of sets in the given options.
1). Numerical data - Data which shows the numeral values or the numbers which tells the exact meaning of quantities like length, width or height.
2). Categorical data - Data which has no numeral values or no logical order.
Therefore, sets which show the numerical data are,
Option (A)
Option (C)
Option (D)
Option (E)
