Which of the following lists of ordered pairs is a function?

2 answers:

3 0

To find if one is a function, you must see if the pattern is the same.
Domains (x) can not have two values
I forget what the y value is called, but there can be the same y- value for multiple x - values

A. is not a function, because its ordered pairs are all over the place, and the value 4 in the x - value has two values assigned - 0 and 3, which makes it invalid.

B. may be a linear function. Its ordered pairs aren't jumping all over the place.
Both the x and y go up one for one, so the function could be y = x + 3

C. isn't because the x - value 2 has two values. Again, that makes this invalid.

D. is invalid because there is two x - values for 2.

Therefore, the answer is B.

sdas [7]

Answer:

$0.5ms^{-1}$

Step-by-step explanation:

Let v be the speed after the collision of both the cars.

Now, momentum is given by: mass × velocity, then by equating the total momentum before and after the collision of the two cars, we get

$500{\times}0.8+300{\times}0=(500+300)v$

⇒ $400+0=800v$

⇒ $400=800v$

⇒ $v=0.5ms^{-1}$

Thus, they are moving at the velocity of $0.5ms^{-1}$

Find the bank discount and proceeds using ordinary interest for a loan to michelle anders for 7,200 at 8.25% annual simple inter

FromTheMoon [43]

Answer:

$145.5

Step-by-step explanation:

Period, t = August 8.to November 8 = 3 months

Simple interest formula :

A = P(1 + rt)

A = final amount =. 7200

7200 = P(1 + (0.0825 * 3/12))

7200 = P(1 + 0.020625)

7200 = P(1.020625)

7200 = 1.020625P

P = 7200 / 1.020625

P = 7054.5009

Bank discount :

A - P

7200 - 7054.5009

= $145.4991

= $145.5

Answer:

This is what came up when I googled it... Sry

Step-by-step explanation:

e^{\ln x}=x

\ln = natural logarithm

e = natural exponent

x = real number

The "common" logarithm has 10 as its base and is denoted as “log.” The following formula allows you to take the natural logarithm by using the base-10 logarithm: ln(number) = log(number) ÷ log(2.71828).
