Given q(x)=3x and r(x)=x2. What is (r∘q)(2)? 36 10 12 24

zmey [24]

Answer:

the answer would be 36.

Step-by-step explanation:

and here go you would get it

R(-5) = -3*(-5) - 4

R(-5) = 15 - 4

R(-5) = 11

Q(X)=3X+3

Q(11) = 3*11 + 3

Q(11) = 33 + 3

Q(11) = 36

So, (Q(R(-2) = 36

hope it is correct..

What is the distance from (-4, -7) to (4, 8) ?

Mila [183]

Answer:

Step-by-step explanation:

We can use this formula:

$\sqrt{(x2-x1)^2 + (y2 -y1)^2}$ where x and y indicate the coordinates of the two points

$\sqrt{4-(-4)^2 + (8-(-7)^2} = \sqrt{64 + 225} = \sqrt{289} = 17$
