Answer:

Correct answer:  second quadrant  angle is 3π/4

                            fourth answer  (2√2 + π) / 4

                            third quadrant angle is 5π/4

                            first answer  (-2√2 + π) / 4

Step-by-step explanation:

Your question does not define the quadrant in which the angle is of the

cos⁻¹ (- √2/2).

If it is in the second quadrant then the angle is 3π/4 and if it is in the third quadrant then the angle is 5π/4

1) second quadrant  angle is 3π/4

sin ( cos⁻¹ (- √2/2)) + tan⁻¹ ( sin ( π/2)) = sin ( 3π/4) + tan⁻¹ 1 =

=  √2/2 + π/4 = (2√2 + π) / 4

2) third quadrant angle is 5π/4

sin ( cos⁻¹ (- √2/2)) + tan⁻¹ ( sin ( π/2)) = sin ( 5π/4) + tan⁻¹ 1 =

= - √2/2 + π/4 = (-2√2 + π) / 4

A catering company loses $110 as a result of delay. The 5 owners of the company must share the loss equally. Which integer repre
san4es73 [151]
What you have to do first is you have 5 owners correct? Well you take anything they're sharing in this case it's delay/debt, so you divide $110 by 5 and you should get $22. This means that each owner would have to pay $22 to the delay.

50 POINTS Really need help, answer a. b. and c.
AleksandrR [38]

Answer:

a) 1 in : 6 in

b)  P=32 inches

    A =60 inches ^2

c) P=  16 ft

    A = 15 ft ^2

Step-by-step explanation:

The drawing is 6 inches tall, while the real flag is 3 ft tall

Change ft to inches

3 ft * 12 inches/1ft = 36 inches

drawing : real life

  6                 36

 Divide each by 6

  1                    6

The scale is 1 to 6

So for every 1 inch on the drawing, there is 6 inches in real life


b)  P= 2(l+w) = 2(10+6) = 2(16) = 32 inches

    A = l*w = 10*6 =60 inches ^2

C)

The drawing is 10 inches by 6 inches

Multiply by the scale factor of 6

Real life is     60 inches by 36 inches

Divide by 12 to get back to ft

                            5ft    by 3 ft

P= 2(l+w) = 2(5+3) = 2(8) = 16 ft

    A = l*w = 5*3 =15 ft ^2
