$(f \circ g)(x) = \sqrt{36x^2+96x+65}\\\\\\(f \circ g)(2) = \sqrt{401}\\\\$

========================================================

Work shown for part 1

$f(x) = \sqrt{x^2-2x+2}\\\\f(g(x)) = \sqrt{(g(x))^2-2(g(x))+2}\\\\f(g(x)) = \sqrt{(-6x-7)^2-2(-6x-7)+2}\\\\f(g(x)) = \sqrt{36x^2+84x+49+12x+14+2}\\\\f(g(x)) = \sqrt{36x^2+96x+65}\\\\(f \circ g)(x) = \sqrt{36x^2+96x+65}\\\\$

----------------------------------

Work shown for part 2

$(f \circ g)(x) = \sqrt{36x^2+96x+65}\\\\(f \circ g)(2) = \sqrt{36(2)^2+96(2)+65}\\\\(f \circ g)(2) = \sqrt{401}\\\\$

I think of a number, I subtract 10 and add 2 . My answer is 20, What was my number

Alina [70]

Answer:

Step-by-step explanation:

x-10+2=20

add -10 and 2 together to simplify the equation

x-8=20

add 8 to both sides to isolate x

x=28

hope this helped!

Two cruise ships leave port at the same time. Ship A sails north at a speed of 20 mph while Ship B sails east at a speed of 40 m

tiny-mole [99]

Answer:

a) D(t) = $20*\sqrt{5} * t$

b) 178.885 miles

Step-by-step explanation:

Ship A travels north at the rate of 20 mph.

Ship B travels east at the rate of 40 mph.

After t hours, Ship A is at a distance of 20t miles from the origin.

Similarly, Ship B is at a distance of 40t miles from the origin.

(a) Distance D(t) = $\sqrt{(20t)^{2}+(40t)^{2}}$

= $\sqrt{400*t^{2}+1600 * (t)^{2}}$

= $\sqrt{2000*t^{2}}$

= $20*\sqrt{5} * t$

(b) Distance between the two ships when t = 4,

= $20*\sqrt{5} * 4$

= $80*\sqrt{5}$ miles

= 80 * 2.236

= 178.885 miles
