Answer:
u = 1/6
Step-by-step explanation:
<u>1</u> (12u - 2 )= 0
3
3×<u>1</u> (12u-2) =0×3

12u -2 =0
<u>12u</u> = <u>2</u>
12 12
u = <u>1</u>

Answer: Tan O= 5/12
Step-by-step explanation:
Cot O=12/5
Looking at the pythagoras theory
Cot= 1/tan
So
Cot O=1/tango
Cross multiply
CotO tan O=1
Make tan the subject of formula
TanO= 1/Cot O
Cot O=12/5
Substitute for cot O
Tan O= 1/12/5
Tan O= 5/12
Answer:
B.) 
Step-by-step explanation:

Then find the Least Common Denominator(LCD); simply just multiply 4 by 3 to get 12; then multiply using the opposite number.

to get:
.
now the denominators is the same on both sides, just subtract the numerator.
27 - 8 = 19
Now simply:
.
Your final answer is 1\frac{7}{12}[/tex].
Answer:b
Step-by-step explanation:
f(x)=x^3+2x^2-5x-6
Put x= -3 in the equation
f(-3)=-3^3+2*3^2-5*3-6
= -27+18+15-6= 0
f(2)= 2^3+2*2^2-5*2-6
=8+8-10-6= 0
