The position of an open-water swimmer is shown in the graph. The shortest route to the shoreline is one that is perpendicular to
Stolb23 [73]

Answer:

Step-by-step explanation:

To define the perpendicular line we need to first know the slope of the reference line graphed.

m=(y2-y1)/(x2-x1) we have points (0,5) and (2,1)

m=(1-5)/(2-0)

m=-4/2

m=-2

For lines to be perpendicular their slopes must satisfy

m1m2=-1, we have a line with a slope of -2 so

-2m=-1

m=1/2, so our perpendicular line is so far

y=x/2+b, it must have point (3,2) so we can solve for b

2=3/2+b

b=1/2, so the swimmer will travel along the line

y=x/2+1/2

The sine decreases from 90 to 270 degrees

The cosine increases from 180 to 360 degrees
The cosine decreases from 0 to 180 degrees

Sine = 0 at 0 and 180 degrees

The base of a triangle is 8 1 3 meters and the height of the triangle is the fourth root of 16 meters meters. What is the area o
just olya [345]

Answer:

The area of triangle is 8 \frac{1}{3}\ m^{2}

Step-by-step explanation:

we know that

The area of a triangle is equal to

A=(1/2)bh

we have

b=8 1/3 m

convert to an improper fraction

8 1/3 m=(8*3+1)/3=25/3 m

The fourth root of 16 is equal to 2

\sqrt[4]{16}=(2^{4})^{1/4}=2

so

h=2 m

substitute

A=(1/2)(25/3)2=25/3\ m^{2}

convert to mixed number

25/3=(24/3)+(1/3)=8+1/3=8 \frac{1}{3}\ m^{2}
