3/4-3=43 Thsts the answer hopes it help
Answer:
r=sqrt45
Step-by-step explanation:
The equivalent expression to the given one is -sin(pi/6).
<h3>
</h3><h3>
Which expression is equivalent to the given one?</h3>
The given expression is:
sin(7pi/6)
Where the argument is in radians.
Remember that:
sin(a + b) = sin(a)*cos(b) + sin(b)*cos(a)
Now we can rewrite:
sin(7pi/6) = sin(pi + pi/6)
Then we can use the above relation to rewrite:
sin(pi + pi/6) = sin(pi)*cos( pi/6) + sin(pi/6)*cos(pi)
And we know that:
sin(pi) = 0
cos(pi) = -1
Then we can write:
sin(7pi/6) = - sin(pi/6)

The area of a parallelogram is base times height.
Multiply 16ft by 18ft.
(16)(18) = 288
The parallelogram is 288 ft².
Answer:
-15/16 or -0.9375
Step-by-step explanation:
3/5x=6 +7x
3x=30+35x
3x-35x=30
-32x=30
x= -15/16
