In order to be categorized as a mathematical sentence , it should have equations or inequalities

So the options that could be categorized as a mathematical sentences are :

A . 4 - a = 11

D. R > 6

E.  2t = 9

hope this helps

100 POINTS! NEED HELP QUICKLY! Look at picture below
Delvig [45]

Answer:

60, 75

150  165

240   255

330  345

Step-by-step explanation:

csc 4 theta = -2 sqrt(3)/3

Write in terms of sin

1/ sin (4 theta) = -2 sqrt(3)/3

Using cross products

-2 sqrt(3) = 3 sin (4 theta)

Divide each side by 3

-2 sqrt(3)/3 =  sin (4 theta)

Take the inverse sin on each side

sin ^ -1(-2 sqrt(3)/3) = sin ^ -1 (sin (4 theta))

240 +360n = 4 theta

and 300 +360n = 4 theta  where n is an integer

Dividing each side by 4

240/4 +360n/4 = 4/4 theta  and   300/4 +360n/4 = 4/4 theta

60 + 90n = theta      and 75 +90n = theta

We want all the values between 0 and 360

Let n=0

60, 75

n=1

60+90=150  and 75+90 =165

n=2

60+180= 240   75+180=255

n=3

60+270 = 330  75+ 270 =345

Complete the table:
Dafna11 [192]

Answer:

d. 0

Step-by-step explanation:

The table can be interpreted as:

\theta = 0

Required

Find sin(\theta)

sin(\theta)

Substitute: \theta = 0

\sin(\theta) = \sin(0)

Using a calculator

\sin(0) = 0

Hence:

\sin(\theta) = 0
