I don't know, this is tricky
Answer:
Step-by-step explanation:
So let's think about what values you can take square root of...
anything but negative values!
So the first one is not correct because you can also take square root of 0,
squareroot of 0 is 0.
So because of this, C and D are both correct, E is correct because root x is an increasing function. B is incorrect because (0,0) is an intercept.
The variables are: x, y
The constant is: 4
The coefficients are: 5, 3
The exponent is: y^2
The best answer is A. The possible roots of this polynomial function 9i and -9i. It is possible that this polynomial function is a quadratic equation. It has a degree of two which means there are two roots and it is possible that the positive and negative value of 9i are its roots.
Answer:
32%
Step-by-step explanation:
The slope of the road is measured as
slope = 
= 
To express as a percentage multiply the fraction y 100% , that is
slope = × 100% = 16 × 2 = 32%
