Answer:
A. If none of the output values are repeated, the relation is a function
Step-by-step explanation:
The reason why A is correct stems from the concept of the vertical line test. If each x-value has their own respective output (y-value), then the relation is a function.
Choice B just states that if none of the x-values are repeated. then the relation is a function. This is not correct because it doesnt follow the vertical line test, which analyzes if any y-values are being repeated
Choice C and D doesnt have any correlation with the vertical line test because an x-value doesnt have to equal a y-value to make the relation a function. Vice versa for any y value being equal to any x-value.
Answer:
143
Step-by-step explanation:
Substitute n=3 into the problem
6(
)-2(
) +3-4
Then figure out squared and power by 3
6(27)-2(9)+3-4
Next multiply
162-18+3-4
Finally, add and subtract
144+3=147
147-4=143
If 40 people were surveyed then it is reasonable
Answer:
25.12
Step-by-step explanation:
the formula of a cone is pi r^2 * h/3
r = radius and h = height
the radius is 2 and the height is 3
and the question says use 3.14 instead of pi so
we have
3.14 * 2^2 * 6/3
2*2 or 2^2 = 4
3.14 * 4 * 6/3
6/3 = 2
3.14 * 4 * 2
4*2 = 8
and 8 * 3.14 is 25.12
