Yes the square root of 1/4 is a rational number
For the first one it's 90.5, I know cause I just took the test and it's right. The second one I'm not sure..
Which set of ordered pairs represents a function? {(0, 1), (1, 3), (1, 5), (2, 8)} {(0, 0), (1, 2), (2, 6), (2, 8)} {(0, 0), (0,
11111nata11111 [884]
Answer: {(0, 2), (1, 4), (2, 6), (3, 6)}
Step-by-step explanation:
For a relation to be considered a function, each x-value needs to have one corresponding y-value--it cannot have more than 1.
Since all the other sets of ordered pairs feature points with two x-values with different y-values, the set above is the only function of the provided options.
a = The cost of the pizza.
b = The cost of the pizza and sales tax.
f(a) = The cost of the pizza.
g(b) = The cost of the pizza and sales tax.
g(f(a)) = The cost of the pizza, sales tax, and delivery fee
A because the line of symmetry is where the two parts of the image will meet
