Identify the domain of the following rational expression:
1 answer:
Answer: D
Step-by-step explanation:
The domain of a function is the allowed 'x' values that the function can take on and produce a defined 'y' value. We can ignore the numerator since it will never be undefined. The denominator on the other hand has a singularity when it equals zero. The reason for this is because we cannot divide by zero. Therefore, lets set the denominator to zero and find which 'x' value makes the function undefined:
Every single real 'x' value will work besides when x = -5. Therefore the answer is D

The weight of solid clay brick is 66.465 ounces, if solid brick with a length of 8 inches, a width of 3.5 inches, and a height of 2.25 inches and the clay weighs 1.055 ounces per cubic inch.
Step-by-step explanation:
The given is,
A solid clay brick in the shape of a rectangular prism.
A length of 8 inches, a width of 3.5 inches, and a height of 2.25 inches.
The clay weighs 1.055 ounces per cubic
Step:1
Formula for volume of rectangular prism,
...................(1)
Where, w - Width of the rectangular prism
h - Height of rectangular prism
l - Length of rectangular prism
From the given,
w = 3.5 inches
h = 2.25 inches
l = 8 inches
Equation (1) becomes,
Volume, V = 63 cubic inches
Step:2
Weight of brick = Volume of brick × Weight per cubic inch
= 66.465 ounces
Weight of brick = 66.465 ounces
Result:
The weight of solid clay brick is 66.465 ounces, if solid brick with a length of 8 inches, a width of 3.5 inches, and a height of 2.25 inches and the clay weighs 1.055 ounces per cubic inch.
AB = 24
BC = 45
AC = 51
cos C = adjacent / hypotenuse
cos C = BC / AC
cos C = 45/51
BC = 45
AC = 51
cos C = adjacent / hypotenuse
cos C = BC / AC
cos C = 45/51
