The ordered pair (3,-4) is among the points on the graph of the function f. Which of the following doesn’t belong to the functio
julia-pushkina [17]

Answer:

(3, 4)

Step-by-step explanation:

A function is a relation that maps elements from a set (the domain, the set of the inputs) into elements from another set (the range, the set of the outputs).

Such that a function can map each element of the domain into only one element of the range.

Then, if a "function" has:

f(x1) = y1

and

f(x1) = y2

It is mapping the input "x1" into two different outputs, then this is not a function.

Now, we know that the ordered pair (3, -4) is among the points on the graph of the function f(x)

(The first value is the input and the second one is the output)

Then the point that does not belong to the graph, is the point that has the same input and different output.

(3, 4)

Any of the other points could belong to the graph.

Margo borrows $500, agreeing to pay it back with 3% annual interest after 14
Akimi4 [234]

Answer:

\$17.50

Step-by-step explanation:

we know that

The simple interest formula is equal to

I=P(rt)

where

I is the Final Interest to pay

P is the amount of money borrowed

r is the rate of interest  

t is Number of Time Periods

in this problem we have

t=\frac{14}{12}\ years\\ P=\$500\\r=3\%=3/100=0.03

substitute in the formula above

I=500(0.03)(\frac{14}{12})

I=\$17.50

Elina [12.6K]

Answer:

Natasha fell asleep for 1.125 hours.

Step-by-step explanation:

We have been given that

Total time spent by Natasha on the beach = 1 1/2 = 3/2 hours

She fell asleep for 3/4 of time she was on the beach.

Hence, the time she fell asleep is given by

t=\frac{3}{2}\times\frac{3}{4}\\\\t=\frac{9}{8}\\\\t=1.125\text{ hours}

Therefore, Natasha fell asleep for 1.125 hours.
