Answer: f·g(x) = 12x³ - 6x² - 10x +5

fog(x) = 24x² - 24x + 1

<u>Step-by-step explanation:</u>

f(x) = 6x² - 5 g(x) = 2x - 1

f·g(x) = (6x² - 5)(2x - 1)

= 6x²(2x - 1) - 5(2x - 1)

= 12x³ - 6x² - 10x + 5

fog(x) = f(2x-1)

= 6(2x - 1)² - 5

=6(4x² - 4x + 1) - 5

= 24x² - 25x + 6 - 5

= 24x² - 25x + 1

<em>I wasn't sure if you wanted multiplication or composition so I solved both.</em>

-BARSIC- [3]

Answer: $5:00\ PM$

Step-by-step explanation:

Given

Truck A speed is $v_a=60\ kmph$

Truck B speed is $v_b=80\ kmph$

Truck A leaves 2 hours before truck B

Distance traveled in the 2 hour

$\Rightarrow 60\times 2=120\ km$

Suppose Truck B will catch truck A after t hours

$\therefore 120+60t=80t$

$\Rightarrow 120=20t\\\Rightarrow t=6\ hr$

Overtake time is $9:00am +2+6=5:00\ PM$
