HELP PLEASE ASAP!!!!

Mathematics
1 answer:
denis-greek [22]2 years ago
3 0

Answer:

see explanation

Step-by-step explanation:

Vertical angles are congruent, hence

2z + 43 = - 10z + 25 ( add 10z to both sides )

12z + 43 = 25 ( subtract 43 from both sides )

12z = - 18 ( divide both sides by 12 )

z = \frac{-18}{12} = - \frac{3}{2}

For questions 1 and 2 graph the exponential function:<br> 1. y=3^x<br> 2. y=2(4.5)^x
Mumz [18]
First, we should know exponential formula, for example exp (LnA) =A, for all A>0, and as for logarythm, LnA^p=pLnA, for all A>0, and for all value of p
so y=3^x=exp[Ln(3^x)]=exp(xLn3), let's search the graph of f(x)=exp(xLn3) f is defined in R, and its teminals limits are 0, and + infinity, f' (x) = Ln3.exp(xLn3), it is positif for all value of x, the function is strictly increasing, f(0)=Ln3, please look at the figure 1
the same method with y=2(4.5)^x, we find y=exp[Ln (2(4.5)^x)]=
exp[Ln (2) +Ln(4.5)^x)], because (LnAB=LnA + LnB), so y=2.exp[Ln(4.5)^x)]=2.exp(x[Ln(4.5)]), which domain is R, nd its teminals limits are 0, and + infinity, f' (x)=2.Ln(4.5) exp(x[Ln(4.5)]), which is positif for all value of x, the function is strictly increasing,and then f(0)=2Ln(4.5)
please look the figure 2
