Answer:
Step-by-step explanation:
log(5) + log(X) = log(5x)
log( 5x) - log(x - 6) = log (5x/(x - 6))
antilog(log(5x/(x - 6)) = antilog(1)
5x / (x - 6) = 10 multiply both sides by x - 6
5x = 10(x - 6) remove the brackets
5x = 10x - 60 Subtract 10 x from both sides
5x - 10x = - 60
-5x = - 60 Divide by 5
x = 12
Answer:
so it probably is <u>1.500</u><u>0</u><u> </u><u>-</u><u> </u><u>2.3979i</u>
If you take 2000 and divide it by 8 then it’s 250. Then you multiple it by 5 and you get 1250. So the answer is C) 1250.
<u>Short answer</u> = C) 8/10
<u>Working :</u>
Tan A = 8/6 = Opposite / AdjacentOpposite = 8 units
Adjacent = 6 units
Hypotenuse = 
= 
= 
= 10 units
Cos B = Adjacent/ Hypotenuse
∴ cos B= 8/10
