Use a ruler and pair of Compass Only, Construct /AB/=10cm/BC/=6cm A B C = 45° Locate the point D inside the triangle such that D is equidistant in AB and AC and 5cm from B. Construct a straight line line throughout D to cut /AB/at x and /AC/ at Y such that AX=AY

your answer would be 12

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
