Hi 
6% increase is multiply by 1,06
done 40 times 
so : 250* 1,06^40 = 2571 , 
 
        
             
        
        
        
9We have such eqation
Q

    /*9   (multiply both sides by 9)
9Q+5=

    /-5 both sides
9Q=

9Q=

9Q=

9Q=-

        /:9 divide both sides by 9
Q=-

![\frac{21}{6*9} =- \frac{21}{54}=[tex] \frac{7}{18}](https://tex.z-dn.net/?f=%20%5Cfrac%7B21%7D%7B6%2A9%7D%20%3D-%20%5Cfrac%7B21%7D%7B54%7D%3D%5Btex%5D%20%5Cfrac%7B7%7D%7B18%7D%20)
 - its the answer
 
        
        
        
This is a true statement, or false depending on whether Alfonso actually did or not. There's no proof.
        
             
        
        
        
Answer:
150 degrees
Step-by-step explanation:
Graphing the complex number we see the angle terminates in the second quadrant. This means the argument, the angle, will be between 90 degrees and 180 degrees.
So if we create a right triangle with that point after graphing it. We see the height of that triangle is 5 because that is the imaginary part. The base of that triangle has length  . The problem is this doesn't give us any part of the angle we want, but it does give us the complementary of the part of the angle that is in second quadrant.
. The problem is this doesn't give us any part of the angle we want, but it does give us the complementary of the part of the angle that is in second quadrant.
Let's find the complementary angle.
So the opposite side of the complementary angle is 5.
The adjacent side of the complementary angle is  .
.




So 90-30=60.
The answer therefore 60+90=150.
 
        
             
        
        
        
Answer:
X = 10
Step-by-step explanation:
if we say 1/2 base = <em>a</em>
a² = 13² - 12²
a² = 25
a = √25
a = 5
if 1/2 base = 5 then x = a × 2
hence X = 5 × 2 = 10
