Answer:

We divide both sides by 100000 and we got:

Now we can apply natural logs on both sides;

And then the value of t would be:

And rounded to the nearest tenth would be 9.2 years.
Step-by-step explanation:
For this case since we know that the interest is compounded continuously, then we can use the following formula:

Where A is the future value, P the present value , r the rate of interest in fraction and t the number of years.
For this case we know that P = 100000 and r =0.12 we want to triplicate this amount and that means  and we want to find the value for t.
 and we want to find the value for t.

We divide both sides by 100000 and we got:

Now we can apply natural logs on both sides;

And then the value of t would be:

And rounded to the nearest tenth would be 9.2 years.
 
        
             
        
        
        
Well 1/8 is smaller than 8/8 so they should not be equal
        
                    
             
        
        
        
Answer:
x = 42
Step-by-step explanation:
The angle between the tangent and the secant is
 difference of the measure of the intercepted arcs, that is
 difference of the measure of the intercepted arcs, that is
x = 0.5( 136 - 52) = 0.5 × 84 = 42
 
        
             
        
        
        
Answer:
D
Step-by-step explanation:
D is the only option where there's always 0 or positive integers inside the radical. The square root of a negative number is imaginary.
