Answer:
1st 2nd and 3rd box
Step-by-step explanation:
1. It does not form a straight line because the output is not proportional. (it does not follow a pattern)
2. the line is not proportional because it does not follow a pattern or ratio of any kind (2468 is proportional because it follows the pattern of 2)
3. the origin is the coordinates (0,0) and the table has that labeled in the diagram therefore the graph does go through the origin
4. the output is not constant (output is 0149) because it does not show any sort of pattern. therefore the 4th box is incorrect.
It cant be made into a standard form
Sorry if incorrect
Answer:
Step-by-step explanation:
We are given an equation 5z² + 9z - 2 = 0 and we are to find possible values of z by solving that equation
We will do the task by factorization method:
5z² + 9z - 2 = 0
We can break the midterm (+9z) in two terms such that when they are multiplied the result is -10z² i.e. equal to product of first and third term of the equation above and their sum is equal to 9z
5z² + 10z - z - 2 = 0
5z(z + 2) - 1(z + 2) = 0
taking z+2 common in the above equation
(z+2)(5z-1) = 0
We can write above equation as
(x+2) = 0 (5z-1) = 0
x = -2; 5z = 1
Well, recall that a whole circle is 2π radians as an angle, 1/3 of that will just be (1/3) * 2π, or (2π)/3 radians.
