Presale tickets (p) are each worth $7: represented in the equation as 7p.

Door tickets (d) are each worth $10: represented in the equation as 10d.

They sold 345 tickets, so p+d=345. They collected $2550, so 7p+10d=2550.

Final answer:

(3) $\left \{ {{7p+10d=2550} \atop {p+d=345}} \right.$

Find the zero of the function f(x)=0.8e^2x -9. Round to the nearest hundredth.

Tju [1.3M]

Answer: x=1.21

Step-by-step explanation:

Given

Function is $f(x)=0.8e^{2x}-9$

To find the zeroes, equate the function equal to zero

$\Rightarrow 0.8e^{2x}-9=0\\\\\Rightarrow e^{2x}=\dfrac{9}{0.8}\\\Rightarrow e^{2x}=11.25$

taking natural logarithm both sides

$\Rightarrow \ln (e^{2x})=\ln (11.25)\\\Rightarrow 2x=2.42\\\Rightarrow x=1.21$

The zero of the equation is 1.21
