Answer:
Option d is correct.
Domain = all real number
range = positive real numbers
Step-by-step explanation:
Given the function: 
Domain of the function is all real numbers except where the expression is undefined.
In this case, there is no real number that makes the expression undefined.
Domain of f(x) = 
= {a | a∈R}
Range is the set of all valid f(x) values.
Therefore, Domain is all real number and the range of function is positive real number
Answer:
D

Answer:
363.6
Step-by-step explanation:
Given in the question,
side of square = 10
Step 1
To find the slant height pyramid we will use pythagorus theorem
13² = 5² + height²
height = √13² - 5²
= 12
Now find the height of the pyramid
12² = 5² + height²
height = 10.91
Step 2
Base area of the pyramid
area = l²
= 10²
= 100
Step 3
Volume = 1/3(height)(basearea)
= 1/3(10.91)(100)
= 363.6
Answer:
x = 3
x = 0
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:
2x^2 - 6x = 0
Pull out like factors
2x * (x - 3) = 0
Solve: 2x = 0
Divide both sides of the equation by 2:
x = 0
Solve: x-3 = 0
Add 3 to both sides of the equation:
x = 3
