Select the correct answer.<br> Which of the following sets of ordered pairs represents a function?

iogann1982 [59]

Answer: {(-8, -14), (-7,-12), (-6,-10), (-5,-8)}

Step-by-step explanation: A function is a relation in which each x-coordinate corresponds to exactly one y-coordinate.

In the relations show here, notice that the first set

of ordered pairs is the only set where each x-coordinate

appears once with a different y-coordinate.

In the other ordered pairs, there is an x-coordinate that appears more

than once and it corresponds to a different y-coordinate.

For example, in the second relation,

the x-coordinate -9 appears twice.

In one case, -9 corresponds to -12 and

in the other case, it corresponds to -8.

So, this is not a function.

What is the difference of the volumes of the two oblique pyramids, both of which have square bases? Round the volumes to the nea

ad-work [718]

Answer:

Step-by-step explanation:

See attachment for the figure

Volume of pyramid can be defined as

V = 1/3 x area of the base x height.

-> Pyramid A:

Volume of Pyramid can be determined by:

V = 1/3 x (2.6cm)² x (2cm) = 4.5067 cm³

Pyramid B:

Volume of Pyramid can be determined by:

V = 1/3 x (2cm)² x (2.5cm) = 3.3333 cm³

Difference b/w two oblique pyramids: 4.5067 cm³ - 3.333 cm³ = 1.17 cm³

By Rounding the volumes to the nearest tenth of a centimeter

1.17cm³ ≈ 1.2cm³

Therefore, the difference of the volumes of the two oblique pyramids is 1.2cm³

The water surface of a sea is 887,200 mi square what is the area rounded to the nearest thousand

lana [24]

Answer:

887,000 is the answer.

Step-by-step explanation:

When rounding a number to the nearest thousands place, pay close attention to the value in the hundreds place. For example, given that the 2 in 200 is less than 5 in 887,200, the 7 in the thousands place will not be rounded up and the hundreds place will round down.
