Given:

The graph of a radical function.

To find:

The domain of the given radical function.

Solution:

We know that, domain is the set of input values or we can say domain is the set of x-values for which the function is defined.

From the given graph it is clear that, for each value of x there is a y-value. It means the function is defined for all real values of x. So,

Domain = Set of all real numbers.

Therefore, the correct option is A.

A ramp that is used to load a truck makes supplementary angles with the ground. The ramp has an incline (<1) of 28. What is t

jeka94

Answer:

Step-by-step explanation:

two angles are said to be supplementary if their sum is 180 degrees

Hence <1 + <2 = 180

Given

<1 = 28

Required

Substitute into the formula

28+<2 =180

<2 = 180-28

<2= 152

Hence the measure of <2 is 152 degrees

Each side of a square is increasing at a rate of 6 cm/s. At what rate (in cm2/s) is the area of the square increasing when the a

My name is Ann [436]

36 cm²s⁻¹ is the rate at which the area of the square is increasing.

Given each side of the square is increasing at a rate of 6cm/s

Area, A = s², s is the side length

=> $\frac{dA}{dt} =\frac{dA}{ds}* \frac{ds}{dt} =2s*(\frac{ds}{dt} )$ {chain rule of differentiation}

$\frac{ds}{dt}$ = 6 cm/s

When A = 9 cm² => 9 = s²

=> s = √(9) => s = 3 cm

Hence, $\frac{dA}{dt}$ = 2 × 3 × 6 = 36 cm²s⁻¹

Hence, 36 cm²s⁻¹ is the rate at which the area of the square increases
