Answer:

d. (x+2)/(-x²-5)

Step-by-step explanation

ƒ(x) = x + 2/(2x²)

The function is undefined when x = 0.

b. ƒ(x) = (2x + 4)/(3x + 3)

The function is undefined when 3x + 3 = 0, i.e., when x = -1.

c. ƒ(x) = (6x - 5)/(x² - 7)

The function is undefined when x² - 7 = 0, i.e., when x = √7.

d. ƒ(x) = (x+2)/(-x²-5) = -(x+2)/(x² + 5)

The function would be undefined if x² + 5 = 0, i.e., if x² = -5. However, the square of a real number cannot be negative.

This function has no excluded values.

The function f(x)=-(x-3)^2 +9 can be used to represent the area of a rectangle with the perimeter of 12 units, as a function of

Ivenika [448]

Maximum area of the rectangle is $9cm^{2}$

<u>Explanation:</u>

<u></u>

Considering the dimensions to be in cm

$f(x) = -(x-3)^{2} +9\\f(x) = -(x^{2} +9 - 6x)+9\\f(x) = -x^{2} +6x\\f'(x) = -2x+6\\-2x+6 = 0\\2x=6\\x=3cm\\\\$

Putting the value of x = 3

$Perimeter = 2(x+b)\\12 = 2(3+b)\\6 = 3+b\\b= 3cm$

$Area of rectangle = x X b\\ = 3 X 3\\ = 9cm^{2}$

Therefore, maximum area of the rectangle is $9cm^{2}$

tan = sin/cos, so tan * cos simplifies down to sin in the numerator. which leaves sin/sin which equals 1.

to make a long story short the answer is 1

Volume of triangular prism base 18in, height 9in, length 24in

padilas [110]

Answer:

1944 in³

Step-by-step explanation:

We are given;

Dimensions of a triangular prism;

Base is 18 inches
Length is 9 inches, and
Length is 24 inches

We are required to determine the volume of the prism

To answer the question we need to know that the volume of a triangular prism is given by;

Volume = 0.5 × Width × height × Length

Therefore;

Volume = 0.5 × 18 in × 9 in × 24 in

= 1944 in³

Thus, the volume of the triangular prism is 1944 in³
