1 subtract 1 2m - 1 = 3m
<span>2 subtract 2 2m = 1 + m </span>
<span>3 subtract m m - 1 = 2 </span>
<span>4 add 2 + m = 3 </span>
<span>5 subtract 2m -2 + m = 1 </span>

Mr. Aydlett is on an island 2 miles offshore and wishes to reach a coastal village 6 miles down a straight shoreline from the po

eimsori [14]

Answer:t=2.11 hr

Step-by-step explanation:

Given

Aydlett is 2 miles offshore and village is 6 miles down a straight line from the Point on the shore nearest the island

Person can row boat at 2 mph in water and can walk 5 mph in land

Let us suppose Person land the boat at a x miles from Point on the shore

thus time taken by him to reach

$t_1=\frac{\sqrt{x^2+2^2}}{2}$

Time taken person to reach village by land is

$t_2=\frac{6-x}{5}$

total time $=\frac{\sqrt{x^2+2^2}}{2}+\frac{6-x}{5}$

we need the time to be least so differentiate t w.r.t to x

$\frac{\mathrm{d} t}{\mathrm{d} x}=\frac{2x}{2\cdot 2\cdot \sqrt{4+x^2}}-\frac{1}{5}$

Equating Above term to zero to get minimum time

$\frac{x}{2\sqrt{4+x^2}}=\frac{1}{5}$

$25x^2=16+4x^2$

$x=\frac{4}{\sqrt{21}}$

Substituting x in time equation

$t=\frac{\sqrt{4+0.761}}{2}+\frac{6-0.872}{5}$

$t=2.116 hr$

Find the area of △DEF with vertices D(−4, −2), E(−1, −8), and F(−7, −8). The AREA of △DEF is ______ square units. *

prohojiy [21]

Answer:

If you plot these points you will see that the base is 6 (distance from E to F, count the squares).

The height will be 6 ( distance from line EF to D, again count the squares).

Using the Area formula you get A = 1/2 (6) (6) = 18
