The answer is B, pi*r/2
Steps
It is a square so each of the angles is 90 degrees (a quarter of 360). So, APD is a quarter of the circle circumference. A full circumference is 2*pi*r, so a quarter circumference is pi*r/2

Consider functions f and g
alexdok [17]

Answer:

A

Step-by-step explanation:

f(x) = \dfrac{x - 16}{x^2 + 6x - 40}

g(x) = \dfrac{1}{x + 10}

f(x) + g(x) =  \dfrac{x - 16}{x^2 + 6x - 40} + \dfrac{1}{x + 10}

f(x) + g(x) =  \dfrac{x - 16}{x^2 + 6x - 40} + \dfrac{(x - 4)}{(x + 10)(x - 4)}

f(x) + g(x) =  \dfrac{x - 16 + x - 4}{x^2 + 6x - 40}

f(x) + g(x) =  \dfrac{2x - 20}{x^2 + 6x - 40}

(A) find F(x) for the indicated values of x, if possible
dem82 [27]

Answer:

A) The indicated values of F(x) for x=-3 and x=5 are F(-3)=-27  and F(5)=125

B) The domain of f is the set of all real numbers

Step-by-step explanation:

Given that the function F is defined by

F(x)=x^3 for x=-3,5

A) To find F(x) for the indicated values of x :

Given F(x)=x^3 for x=-3,5

  • Put x=-3 in the given function

F(-3)=(-3)^3

=(-3)\times (-3)\times (-3)

=-27

Therefore F(-3)=-27

  • Put x=5 in the given function

F(5)=(5)^3

=(5)\times (5)\times (5)

=125

Therefore F(5)=125

The indicated values of F(x) for x=-3 and x=5 are F(-3)=-27  and F(5)=125

B) To find the domain of f :

The domain of the f in the given expression is the set of all real numbers except where the expression x^3 is undefined. In this case, there is no real number that makes the expression undefined.

The domain of f is the set of all real numbers

Compare fraction 2over 3 and 7 over 8 which is greater
Paul [167]
If you use a calculator to find the exact decimal of these fractions, you can easily find this out.

2/3 as a decimal equals:  0.6666 (repeating sixes)

7/8 as a decimal equals:  0.875

0.875 > 0.666

7/8 > 2/3

7 over 8 is greater!  Hope this helps! :)
