<span>The best way to solve each equation is:
 
</span> 1) 5x2 + 12x - 3 = 0 -----> solve by quadratic formula 
 2) 4x2 - 25 = 0 -----------> solve by square root method 
 3) x2 - 5x + 6 = 0 --------> solve by factoring
 4) x2 - 4x = 8 -------------> solve by completing the square

P(x)=150(1.07)x what is x
Gekata [30.6K]
Hello,

P(x)=150*1.07^x
==>ln(P(x)/150)=x*ln(1.07)
==>x=(ln(P(x)-ln(150))/ln(1.07)
If you know how much is P(x) then you have the answer.

Find the exact value of csc 5pi/6
Leona [35]

Answer:

csc 2 (csc \frac{5\pi}{6} = csc 150 = csc 30 = csc 2)

Step-by-step explanation:

csc \frac{5\pi}{6} is in the 2nd Quadrant where only sin, and csc are positive.

csc (\frac{5\pi}{6})=csc (\pi -(\frac{5\pi}{6}))=csc(\frac{5\pi}{6})

but csc \frac{5\pi}{6} = \frac{1}{sin (\pi/6)} = \frac{1}{sin 30} = \frac{1}{1/2} =2

Lef f be the function given by f(x)=x^3-6x^2+8x-2. what is the instantaneous rate of change of f at x = 3.
Anit [1.1K]
First find the derivative of f(x):-

f'(x)  =  3x^2 - 12x + 8  

So instantaneous rate at x = 3 

=  3(3)^2 - 12(3) + 8 

=  27 - 36 + 8  =   -1  answer
