Which table represents a direct variation?

Mathematics
1 answer:
Galina-37 [17]3 years ago
8 0

Answer:  Table B is a direct variation.

Step-by-step explanation:

Table A contains data that fits the expression y = x+3.  This is not a direct variation.  The ratio of x and y is not a constant.  Table B matches the expression y = 3x.  This is a direct variation.  Table C can be expressed as y = x - 3.  This is not a direct variation, for the same reason as Table A.

A satellite 200 miles above the earth is orbiting the earth once every 4 hrs. How far does the satellite travel in 1 hr
Dima020 [189]

Assume the radius of the the earth is ~4000 miles.

radius of orbit = 4000 +200 = 4200 miles

In 4 hrs it orbits 2Pi*r =2pi*4200= 8400pi miles

In 1 hr it would travel (8400pi/4 )

= 2100pi = 6597.3445 miles (exact value)

= 6597 miles ( approximate)

Richard’s checking account balance was $57.34 at the beginning of the week. During the week, he recorded the transactions below.
Tomtit [17]

Answer:

US$ 132.45

Step-by-step explanation:

See attachment for the missing table.

Given:

Richard’s checking account balance at the beginning of the week = $57.34

<u>Richard’s account balance at the end of the week from the given table:</u>

Deposits of the week = US$ 163.75

Expenses of the week = Groceries + Credit card bill + Gas

Expenses of the week = 25.37 + 50 + 13.27

Expenses of the week = US$ 88.64

Richard’s account balance at the end of the week = Richard’s checking account balance at the beginning of the week + Deposits of the week - Expenses of the week

Replacing with the real values:

Richard’s account balance at the end of the week = 57.34 + 163.75 - 88.64

                                                                                    =US$ 132.4

Does the table show a proportional relationship? If so, what is the value of y when x is 11
prisoha [69]

Answer:

Yes, the table shows a proportional relationship

The value of y when x is 11 is 1331

Step-by-step explanation:

Let us check the relation between x and y in the table

∵ x = 4 and y = 64

∵ 64 = 4³

∴ y = x³

∵ x = 5 and y = 125

∵ 125 = 5³

∴ y = x³

∵ x = 6 and y = 216

∵ 216 = 6³

∴ y = x³

∵ x = 10 and y = 1000

∵ 1000 = 10³

∴ y = x³

∵ All the values on the table give the same relation

∴ x and y are proportion

∴ The table shows a proportional relationship

∵ y = x³

∵ x = 11

∴ y = (11)³

∴ y = 1331

∴ The value of y when x is 11 is 1331
