The answer is 2/1, I think. :)

Choose all of the transformations that would change a triangle into one that is similar, but not congruent. Which transformation
Vsevolod [243]

You didn't supply a list.  The so-called rigid transformations of translation, rotation and reflection create congruent triangles.

Generally it's dilation by a factor about a point is preserves similarity but not congruency.  Any transformation which includes such scalings but is otherwise rigid also preserves similarity but not congruency.

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

What is the solution to the system of equations? y = 2x – 3.5 x – 2y = –14
katrin2010 [14]
Hello,

Answer C

y=2x-3.5==>2x-7=3.5 (1)
x-2y=-14 (2)

(1)-2*(2)==>3y=28+3.5 ==>y=31.5/3==>y=10.5
x=-14+2*10.5==>x=7
sol={(7,10.5)}
