Which mapping diagram does NOT represent a function from x > y ?

Answer:

Step-by-step explanation:

In a function, each x value must have a singular y value. This means that one x-value (the values on the left) may not have a line pointing to 2 different y-values (the values on the right). In the first relation, the x-value of 6 points to both 4 and 6. This means that the value repeats, and in a function x-values cannot repeat.

However, y-values can repeat. So, situations like that seen in D, where both the x-values of 2 and 4 equal the y-value of 6 are fine.

Express the -0.345 in the form of p\q and reduce it to the lowest term

Mamont248 [21]

Answer:

-69/200

Step-by-step explanation:

-0.345 is in decimal form.

In Fractional form (p/q)

=-345/1000

To simplify, divide the numerator and the denominator by the G.C.D(Greatest Common Divisor) of p and q.

In this case,G.C.D of 345 and 1000 is 5.

Simplified form=-69/200 [ANS]

Find the surface area of the cylinder. Round your answer to the nearest hundredth.

horsena [70]

Answer:

C. 795.45 in^2

Step-by-step explanation:

The formula for the surface area of a cylinder is ...

SA = 2πr^2 +2πrh = 2πr(r +h)

For r=6 and h=15.1, the surface area is ...

SA = 2π(6)(6 +15.1) = π(12)(21.1) = 253.2π

SA ≈ 795.45 . . . . square inches
