Flura [38]2 years ago

Answer:

Yes, no two ordered pairs in this list have the same first coordinate

Step-by-step explanation:

we know that

A <u>function</u> is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

That means that there can be only one ordered pair with the same value of x.

therefore

In this problem F is a function, because all the ordered pairs of the list don't have the same first coordinate

The length of a rectangle is 3 inches longer than half of its width. The area of the
IgorLugansk [536]

Answer:

Width = 26 inches

Step-by-step explanation:

The area of the rectangle is:

area = (length*width)

416 = a*b

a = b/2  + 3

a = length

b = width

then:

416 = (b/2 + 3) (b)

416 = b*b/2 + b*3

416 = b²/2 + 3b

0 = b²/2 + 3b - 416

b = {-(+3)±√((3²)-(4*1/2*-416))} / (2*1/2)

b = {-3±√(9+832)} / 1

b = {-3±√841}

b = -3±29

only take the positive value becuse is a natural number

b = -3+29

b = 26 inches

a = b/2 + 3

a = 26/2 + 3

a = 13 + 3

a = 16 inches

Check:

416 = 16 * 26

Sofia takes 10mg of a medicine whose concentration in blood decreases by a factor of one half every day. Let t be the number of
adelina 88 [10]

Answer:

L = 10(\frac{1}{2} )^{t-4}

Step-by-step explanation:

If t is the number of days since Sofia took the medication of 10 mg, then the amount of medication in her system after t days will be S = 10(\frac{1}{2} )^{t}.

So, the concentration of medicine in blood decreases by a factor of one half every day.

If we count the number of days from today and Lexi takes 10 mg of the same medicine four days later then the amount of medicine left on her body after t days will be L = 10(\frac{1}{2} )^{t-4}. (Answer)
