Answer:

The value of f(2) would be -40.

Step-by-step explanation:

Given function is,

f(x) = 2x^3 - 3x^2 - 18x - 8

Substituting x = 2 in the above function,

We get,

f(2) = 2(2)^3 - 3(2)^2 - 18(2) - 8

=2(8) - 3(4) - 36 - 8

=16 - 12 - 44

\implies f(2)= -40

Hence, the value of f(2) would be -40.

Given: <PQR is a right angle Prove: <PQS and <SQR are complemantary​
amm1812

Answer:

see the explanation

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

m∠PQS+m∠SQR=m∠PQR ----> equation A (by Addition Angle Postulate)

we have that

m∠PQR=90° ----> equation B given problem (because is a right angle)

substitute equation B in equation A

m∠PQS+m∠SQR=90°

Remember that

Two angles re complementary is their sum is equal to 90 degrees (Definition of complementary angles)

therefore

m∠PQS and m∠SQR are complementary angles

If f(x)=2x² +5√(x-2), complete the following statement:
myrzilka [38]

By functional analysis we have the following conclusion about the function given: The domain for f(x) is all real numbers greater than or equal to 2.

<h3>How to determine the domain of a function with radical components</h3>

Domain is the set of x-values such that the value of the function exists. By algebra we know that the domain of polynomials is the set of all <em>real</em> numbers, whereas the domain of <em>radical</em> functions is the set of x-values such that y ≥ 0. If we know that f(x) = 2 · x² + 5 · √(x - 2), then the domain is restricted by the <em>radical</em> component and defined by x ≥ 2.

By functional analysis we have the following conclusion about the function given: The domain for f(x) is all real numbers greater than or equal to 2.
