The problem refers to right triangle abc with c = 90°. use a calculator to find sin a, cos a, sin b, and cos b. round your answers to the nearest hundredth. b = 8.87, c = 9.65

Step-by-step explanation:

From the figure, AB=c=9.65, AC=b=8.87 and BC=a

Now,

Therefore, BC=3.80

Now, SinA=

CosA=

SinB=

CosB=

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
