Functions are a set of points that show how dependent variables change through independent variables.
Defining a Function
In functions, each x-value is assigned to exactly one y-value. This means that x-values do not repeat. So, if there is one x-value more than once in a set, then it cannot be a function.
For example, set B has the x-value 3 and 4 repeated twice. Thus, it does not represent a function.
Graph of a Function
Functions can also be defined through a graph. Just like with coordinate points, x-values do not repeat on the graph. You can use the vertical line test to see if a graph is a function. If you can draw a vertical line at every point on a graph without it ever intersecting with the graph more than once, then it is a function.
Answer:
-(18/49)=n or approximately n=-0.367
Step-by-step explanation:
our equation is: m(nx²-y)/z=5n in order to find n we need to substitute the values given in the question. when we substitute we get:
6*(n*(-2)²-(-3))/(-5)=5n
6(4n+3)/(-5)=5n (we distribute the 6 in the numerator)
24n+18/-5=5n (we multiply both sides by (-5))
24n+18=-25n (we subtract 24n from both sides)
18=-49n (divide both sides by (-49))
-(18/49)=n or approximately n=-0.367
Answer:
24.72 m
11.53 m
Step-by-step explanation:
Horizontal distance AB can be obtained from △ABC
From trigonometry :
Sin18° = opposite / hypotenus
Sin18° = AB / 80
AB = 0.3090169 * 80
AB = 24.72 m
The height BT, of tower from △ABT
From trigonometry :
Tan25° = opposite / Adjacent
Tan25° = h / 24.72m
h = Tan25 * 24.72
h = 11.527
h = 11.53 m
Hence, height of tower BT = 11.53 m
