A.) Yes, every input is paired with exactly 1 output.
kondaur [170]4 years ago

ANSWER:

In the explanation. :)

Step-by-step explanation:

Th answer is D. Simply because when you have a function the Input needs to be paired with exactly one output. 2 inputs can not be paired together, if you want it to be a function. It would also be nonlinear because if you graph it, it would not be in a straight line.

Hope this helps. Have a great day.

A 25 ft. ladder resting against the side of a building forms a right triangle with the ground. The bottom of the ladder is 7 ft.
ruslelena [56]

Answer:

The correct answer is 24

Step-by-step explanation:

to solve this you will need to use the pathagreom theorum

a^{2}+b^{2}=c^{2}

A= one side lenth

B= the secons side lenth

C= hypotnuse

It is helpfull to draw out the situation

you know that the latter is 25 ft, that is your hypotnuse

you also know that the 7 ft away from the base of the building is one of the side lenths, lets call it side a

so plug the numbers into the equation

7^2 + b^2 = 25 ^2

you leave b^2 alone because that is the side you are trying to find

now square 7 and 25 but leave b^2 alone

49 + b^2 = 625

now subtract 49 from both sides

b^2 = 576

now to get rid of the square of b you have to do the opposite and square root both sides removing the square of the B and giving you the answer of..........

B= 24

Hope this helped!! I tryed to explain it as simpil as possiable

HELP!!!! Choose the correct answer. Which expression, when evaluated,
blagie [28]

We will check each options and verify it

(a)

18-2m

we can plug m=2

18-2\times 2

18-4

14

so, this is FALSE

(b)

7x-\frac{x}{3} >19

we can plug x=3

7\times 3-\frac{3}{3} >19

21-1 >19

20 >19

so, this is TRUE

(c)

6x-1>4x+5

we can plug x=3

6\times 3-1>4\times 3+5

18-1>12+5

17>17

so, this is FALSE

(d)

2x^2-3x+1

now, we can plug x=2

2(2)^2-3(2)+1

8-6+1

3

So, this is FALSE
