Given the exponential equation 3x = 243, what is the logarithmic form of the equation in base 10?
weeeeeb [17]
The answer is x= \frac{log_{10} (243 )}{log_{10} (3 )}

3^{x} =243
Logarithm both sides of the equation:
log_{10} (3^{x} ) = log_{10} (243 )
Since: log (a^{b}) = b*log(a), then: log_{10} (3^{x} ) =x*log_{10} (3 )
Back to our equation:
log_{10} (3^{x} ) = log_{10} (243 ) \\ 
x*log_{10} (3 ) = log_{10} (243 ) \\ 
x= \frac{log_{10} (243 )}{log_{10} (3 )}

For the following polynomial, find P(a), P(-x) and P(x + h).<br><br> P(x) = 7x-6
torisob [31]

Answer:

Step-by-step explanation:

Hello, please consider the following.

P(a) = 7 * a - 6

P(-x)= 7 *(-x) - 6 = -7x - 6

P(x+h) = 7 * (x+h) - 6 = 7x + 7h - 6

Hope this helps.

Thank you.

The circumference of a
timama [110]

9514 1404 393

Answer:

  • 160,000 m²
  • 16 ha

Step-by-step explanation:

The side length of a square is 1/4 of the perimeter, so the side length of the square orchard is (1600 m)/4 = 400 m.

The area of a square is the square of the side length, so the area of the orchard is (400 m)² = 160,000 m².

A hectare is 10,000 m², so the area of the orchard in hectares is ...

  16·(10,000 m²) = 16 ha
