Answer:

Domain : [0, ∞) {x | x ≥ 0} (equal to 0 all real numbers greater than or equal to 0).

Step-by-step explanation:

The given function is f(x) = √9x = 3√x

For this function f(x) is defined only if x ≥ 0 because for x < 0 the function is not defined.

f(-x) = 3√(-x) which is not defined.

Therefore domain of this function is domain: [0, ∞) {x | x ≥ 0}

Answer:

The domain is all real numbers greater than or equal to zero

Step-by-step explanation:

∵ f(x) = √9x

∴ The domain is all values of x ≥ 0

    because if x = number less than zero it will be negative

    There is no value in the real number for √-ve values

∴ The domain is all real numbers ≥ 0

What is the area of triangle PQR? Round to the nearest tenth of a square unit.
larisa86 [58]
ANSWER

111.3 square units.

EXPLANATION

The formula for calculating the area of a triangle is.

Area = \frac{1}{2} \times base \times height
Let us the side of the triangle with side 12 units to be the base of the triangle.

Then the height of the triangle can be determined from the diagram using trigonometry.

\sin(68 \degree) = \frac{height}{20 }

height = 20 \sin(68 \degree)

height = 18.54

We now plug in the values in to the formula to obtain,

Area = \frac{1}{2} \times 12 \times 18.54

Area = 111.3 \: square \: units
