Solve this equation please

nalin [4]

Step-by-step explanation:

Number 1

$log_{10}( {x}^{2} - 3x + 12 ) = 1 \\ log_{10}( {x}^{2} - 3x + 12 ) = log_{10}(10) \\ cancelling \: both \: logs \: we \: have \\ {x}^{2} - 3x + 12 = 10 \\ {x}^{2} - 3x + 12 - 10 = 0 \\ {x}^{2} - 3x + 2 = 0 \\$

$solve \: \: by \: factorisation \: method \\ {x}^{2} - 2x - x + 2 \\ {x}(x - 2) \: - 1(x - 2) \\ (x - 2)(x - 1) \\ therefore \: x = 2 \: or \: x = 1$

Find the circumference of a circle whose area is 452.16 square meters. (Use 3.1416 as the value of π.) A. 24 meters B. 37.6992 m

Shkiper50 [21]

<span>D is the correct answer. To work out the radius of a circle from the area, find the square root of the area/pi. This makes square root of 452.16/3.1416 = 12. The circumference is 2 x pi x r = 2 x 3.1416 x 12. The circumference is 75.3984.</span>
