Answer: $-0.25$

Step-by-step explanation:

The given function : $f(x)=\dfrac{1}{4}x$

To find the value of the given function at -5, we need to substitute the value of -5 in the given function, we get

$f(-5)=\dfrac{1}{4}\times-5\\\\\Riaghtarrow\ f(-5)=\dfrac{-5}{4}\\\\\Riaghtarrow\ f(-5)=-1\dfrac{1}{4}$

Hence, the value of $f(x)=\dfrac{1}{4}x$ at $x =-5=-1\dfrac{1}{4}\ or \ -0.25$

to avoid a large shallow reef a ship set a course from point a and traveled 24 miles east to point b . the ship them turn and tr

First, we are going to find the distance traveled by the ship adding the tow distances:
Distance traveled= 24 mi +33 mi=57 mi

Next, we are going to use the Pythagorean theorem to find the distance from $a$ to $c$ :
$d^2=24^2+33^2$
$d^2=576+1089$
d^2=1665
$d= \sqrt{1665}$
$d=40.8$ mi

Finally, we are going to subtract the two distances:
57 mi -40.8 mi= 16.2 mi

We can conclude that <span>if the ship could have traveled in a straight lime from point a to point c, it could have saved 16.2 miles.</span>
