b. 5 - 9/n
c. 1/2(6n/22)
d. 9 - 2(n - 7)
e. 11 - n to the second power
Answer: The perimeter is when you add all of the sides together, and the area is when you multiply the sides together
Step-by-step explanation:
Answer: The Area of the triangle is 85.5. Area of the semi-circle 127.235
Step-by-step explanation: Add them together to get your answer. So then techinically you won't be cheating :) .
The functions b,d, and f have complex roots{ as the graph has no intersections with the x-axis}
Function: A function is defined as a relationship between a set of inputs that each have one output. A function is a relationship between inputs in which each input is related to exactly one output. Every function has a domain and a codomain, as well as a range. In general, a function is denoted by f(x), where x is the input. A function's general representation is y = f. (x).
Complex roots: Complex roots are the fictitious roots of equations represented by complex numbers. Because taking the square root of a negative number is impossible, we convert it to a complex number.
In the shown figure the functions b,d and f do not touch the x-axis which means it has complex roots {image attached}
Therefore, The function b,d, and f have complex roots{ as the graph has no intersections with the x-axis}
