Answer:
-1
Explanation:
3π / 4 = (3*180) / 4 = 135 degrees
Since 135 is in the 2nd quadrant, therefore:
tan (135) = - tan (45) = -1
cot θ = 1/tanθ
Therefore:
cot (3π / 4) = 1/tan(3π / 4)
cot(3π / 4) = -1
Hope this helps :)
Answer:
X=4
Step-by-step explanation:
-2-10x+100=7x+30

x=4
Answer:
Step-by-step explanation:
Convert the mixed number in the denominator to an improper fraction by multiplying the big number times the denominator and adding the numerator.
Leave the same denominator.
Let's do the same with the fraction in the numerator.
Our new division is;
Now, to get rid of the fraction in the denominator, multiply by the reciprocal fraction. The reciprocal is the inverted fraction.
If our fraction is the reciprocal is
This eliminates the denominator.
Now convert this fraction to a mixed number by dividing.
64/35=1
35
-------
29
-------------------------------------------
1 is the big number, 29 the numerator and 35 the denominator.
Do not forget about the negative sign in front of it.
