The sum of the speeds two trains is 717.6 miles per hour. If the speed of the first train is 6.4 mph faster than that of the sec

damaskus [11]

Train 1 = x + 6.4

Train 2 = x

(x) + (x + 6.4) = 717.6

2x + 6.4 = 717.6

2x = 711.2

x = 355.6

Train 1 = 355.6 + 6.4 = 362 mph

Train 2 = 355.6 mph

Hope this helps!! :)

Use the remainder theorem to determine the remainder when 3t²+5t-7 is divided by t-5

Brrunno [24]

$f(t)=3t^2+5t-7\implies f(5)=3(5)^2+5(5)-7=93$

which means the remainder upon dividing $f(t)$ by $t-5$ is 93.

This is because we can write

$\dfrac{f(t)}{t-5}=q(t)+\dfrac{r(t)}{t-5}$

where $q(t)$ is the quotient and $r(t)$ is the remainder. Multiplying both sides by $t-5$ , then evaluating at $t=5$ makes the $q(t)$ term vanish, leaving the remainder:

$f(t)=q(t)(t-5)+r(t)\implies f(5)=r(5)$
