The functions r and s are defined as follows.

irina1246 [14]

Answer:

r(s(-2)) = -2

Step-by-step explanation:

We are given these following functions:

$r(x) = -2x + 2$

$s(x) = x^2 - 2$

Find the value of r(s (-2)).

First we find the composition of r and s functions. It is:

$r(s(x)) = r(x^2-2) = -2(x^2-2) + 2 = -2x^2 + 6$

At x = -2

$r(s(-2)) = -2(-2)^2 + 6 = -8 + 6 = -2$

r(s(-2)) = -2

Estimate the total cost of 31 televisions at £196.50 each and 19 DVD players at £50.99 each

Gwar [14]

Answer:

Solution,

Cost of one television=£196.50

cost of 31 televisions:

 $= 196.50 \times 31 \\ = 6091.5$ 

Cost of one DVD player=£50.99

Cost of 19 DVD player:

 $= 50.99 \times 19 \\ = 968.81$ 

Now,

Total cost

= cost of 31 televisions + cost of 19 DVD player

=6091.5+968.81

=£7060.31

Hope this helps...

How do you find the missing angle of a triangle when all other angles are there?

olya-2409 [2.1K]

All angles in a triangle add up to 180 degrees. So, if you are missing an angle, add up the degrees of the angles present and subtract that from 180. That will be the value of the missing angle in degrees.
