RUDIKE [14]3 years ago

Answer:

(-∞, ∞)

Step-by-step explanation:

Given,

f(x)=x^2-1 \ and\ g(x)=2x-3

Then (fºg)(x) would be ,

(2x-3)^2-1\\4x^2-12x+9-1\\4x^2-12x+8

Since this is a polynomial, we know domain of a polynomial is all real number.

Therefore the domain of this (fºg)(x) is (-∞, ∞).

A rectangle is transformed according to the rule r0, 90º. the image of the rectangle has vertices located at r'(–4, 4), s'(–4, 1
Korvikt [17]

Answer:

Clockwise vertices of q' ( -3 ,4) →→ q( 4 , 3 ).

Counter clock wise rule : q' (-3 ,4 ) →→ q( -4 , -3 ).

Step-by-step explanation:

Given  : rectangle has vertices located at r'(–4, 4), s'(–4, 1), p'(–3, 1), and q'(–3, 4)

To find :  transformed according to the rule 90º , what is the location of q?

Solution : we have given that

vertices located at r'(–4, 4), s'(–4, 1), p'(–3, 1), and q'(–3, 4).

By the rule of 90º rotation clock wise rule : (x ,y ) →→ ( y , -x )

90º rotation counter clock wise rule : (x ,y ) →→ ( -y , x ).

Then   Clockwise vertices of q' ( -3 ,4) →→ q( 4 , 3 ).

counter clock wise rule : q' (-3 ,4 ) →→ q( -4 , -3 ).

Therefore, Clockwise vertices of q' ( -3 ,4) →→ q( 4 , 3 ).

counter clock wise rule : q' (-3 ,4 ) →→ q( -4 , -3 ).

3) This is definitely a positive association, but the question is - is it linear? 
Since a somewhat straight line can be drawn through the points, it is linear. 

<span>Answer: positive linear association 
</span>
4) Find the slope using the formula 
m =  \frac{y2 - y1}{x2 - x1}

m = 43 - 48/ 4 - 2 = -5/2 = -2.5
Negative association, but is it linear? Lets find out

Oh no! It seems that their is not a pattern in the association, so its nonlinear!

Answer: Negative nonlinear association

5) <span>m = \frac{y2 - y1}{x2 - x1}
m = 80 - 66/ 5 - 3 
m = 14/2
m = 7

Positive! But is it linear??
Let us draw a graph this time. 

I know my graph is messy, but can you see the nonlinear-ness? It doesnt form a straight line!

Answer: Positive nonlinear association

If you reverse the first two letters
Na
Fe
Hg
Sn

They are actually symbols for elements
Na - Sodium
Fe - Iron
Hg - Mercury
Sn - Tin

Since Sn is a symbol for Tin and each pair of letters imply the starting letter of the element they are symbolizing, the answer is
1) T<span />
