Answer:
346/389
Step-by-step explanation:
First determine how many were not arm tattoos
389-43
346
P( not arm) = not arm /total
= 346/389
Answer:
5.7 years
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
substitute in the formula above
Solve for t
Applying property of exponents
Applying log both sides
![log(\frac{11.8}{9})=log[(1.011875^{4})^{t}]](https://tex.z-dn.net/?f=log%28%5Cfrac%7B11.8%7D%7B9%7D%29%3Dlog%5B%281.011875%5E%7B4%7D%29%5E%7Bt%7D%5D)
![log(\frac{11.8}{9})=(t)log[(1.011875^{4})]](https://tex.z-dn.net/?f=log%28%5Cfrac%7B11.8%7D%7B9%7D%29%3D%28t%29log%5B%281.011875%5E%7B4%7D%29%5D)
![t=log(\frac{11.8}{9})/log[(1.011875^{4})]](https://tex.z-dn.net/?f=t%3Dlog%28%5Cfrac%7B11.8%7D%7B9%7D%29%2Flog%5B%281.011875%5E%7B4%7D%29%5D)

Answer:
84x¹²
Step-by-step explanation:
To simplify this expression, we work from left to right:
4x(-3x⁸)(-7x³)
Multiplying the coefficients of the first two, we have 4(-3) = -12. Using the laws of exponents, multiplying powers with the same base means we add the exponents; this gives us x(x⁸) = x¹⁺⁸ = x⁹. This gives us
-12x⁹(-7x³)
Multiplying the coefficients, we have -12(-7) = 84. Using the laws of exponents, for the variable we have x⁹(x³) = x⁹⁺³ = x¹²
This gives us
84x¹²
