Identify the function as either a constant, direct variation, absolute value or greatest integer function f (x)=-4
boyakko [2]
Answer: Constant

No matter what the input x is, the output f(x) is going to be -4. Therefore, the output is constant. 

Note: f(x) can be interchanged with y. So we can say y = -4.

Find the value of x.<br> 7<br> Х<br> 3<br> Z<br> X =√[?]<br><br> Pls help explain !!
Alisiya [41]

Answer:

Answer:

 x = √70

Step-by-step explanation:

The triangles shown are all similar, so the corresponding sides are proportional.

 hypotenuse/long side = x/7 = (7+3)/x

Cross-multiplying gives ...

 x^2 = 7(10)

 x = √70

_____

You will note that the value of x (the long side) is the geometric mean of the long segment and the whole hypotenuse.

A similar "geometric mean" relation holds for the short side:

 BC = √(CD·CA)

There is yet another "geometric mean" relation that holds for the altitude:

 BD = √(CD·AD)

Step-by-step explanation:

Which expression is not a perfect square trinomial?
puteri [66]

Answer:

Remember that a perfect square trinomial can be factored into the form (a+b)^2

or (a-b)^2

Examples:

(x+2)(x+2) is a perfect sq trinomial --> x^2+4x+4

(x-3)(x-3) is a perfect sq trinomial --> x^2-6x+9

(x+2)(x-3) is not a perfect square trinomial because its not in the form (a+b)^2 or (a-b)^2

Now to answer your question,

for the first one, x^2-16x-64, you cannot factor it so it is not a perfect square trinomial

for the second one, 4x^2 + 12x + 9, you can factor that into (2x+3)(2x+3) = (2x+3)^2 so this is a perfect square trinomial

for the third one, x^2+20x+100 can be factored into (x+10)(x+10) so this is also a perfect square trinomial

for the fourth one, x^2+4x+16 cannot be factored so this is not a perfect square trinomial

Therefore, your answer is choices 2 and 3
