I think that the only way you would get no solution, it would be zero
The items below discuss each choices and states whether the statements are true or false.
(A) It can be seen from the table that if the value of x is -2 then, the value of y is 6. Therefore, this statement is TRUE.
(B) The term range refers to the values of y that can be the result of substituting any x value to the equation generated from the given data. As per table, it can be seen that the values of y can range from negative infinity to positive infinity so long as the number of real. This statement is TRUE.
(C) The choice says f(5) = -2. This statement is FALSE because it should be written as, f(-2) = 5 given that x is the independent variable and y or f(x) is the dependent variable.
(D) The domain is the range of number that the values of x may take. As per the table, the domain is at -2 to 6. Therefore, this statement is TRUE.
Answer:
n = 11
Step-by-step explanation:
The side length of a triangle are n,n-3 and 2(n-2).
The perimeter of the triangle, P = 37 units
We need to find the value of n.
Perimeter = sum of all sides
n+n-3 +2(n-2) = 37
2n-3+2n-4 = 37
4n -7 = 37
4n = 37+7
4n = 44
n = 11
So, the value of n is 11.
Answer:
cos (
) = 
Decimal value: −0.9238795325...
Step-by-step explanation:
Write,
cos = cos 
= −cos 
Now using half angle formula, cos(x) = 2 cos²(
) − 1, we can write cos 
= 2
cos²() − 1
This means 
+ 1 = 2 cos²()
2 cos²() = 
cos²() = 
cos() = 
Simplify,
= 
= 
Hence,
cos () = −cos () =
Option D. Any transformation that undergoes a 360 degree rotation maps onto itself, no matter the polygon.
