Use properties of exponents to write an equivalent expression 4.4.4.equals 4

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years

step-by-step explanation:

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
