Answer:
Option 2. (x²- 4x + 5) is the quotient.
Step-by-step explanation:
We have to find the quotient of .
Now we will factorize numerator as
(-5x³ + 20x² -25x) = -(5x³ - 20x² +25x) = -5x(x² - 4x + 5)
Now we can easily divide this term by the term given in the denominator.
= -5x(x² - 4x +5)/(-5x)
Therefore the quotient will be (x²- 4x + 5).

Answer:
Step-by-step explanation:
Given: f(x) = 4(3x - 5)
Is required to find f⁻¹(x)
f(x) = y = 4(3x - 5)
∴ y = 4 * 3x - 4 * 5
∴ y = 12x - 20 ⇒ add 20 to both sides
∴ y + 20 = 12x ⇒ divide both sides by 12
∴
Replace the places of x and y.
∴

Answer:
cosR =
Step-by-step explanation:
assuming the right triangle has ∠ Q = 90° with legs 5 and 12
then this is a 5- 12- 13 right triangle with hypotenuse PR = 13 cm
then
cosR = =
=
