Answer:

For the Y= it is -3 and 4

For the 0= it is also -3 and 4

Step-by-step explanation:

These are the correct answers because when finding the solutions to an equation in Vertex Form, you take both of the X values and switch their signs to get the answer. This is proven to be right because they were the right answers on ED.

Aubrey invested $61,000 in an account paying an interest rate of 1.9% compounded continuously. Assuming no deposits or withdrawa

Hitman42 [59]

Answer: 9.9 years.

Step-by-step explanation:

If interest is compounded continuously, then formula to compute final amount A = $Pe^{rt}$ , where P =initial amount, r= rate of interest , t=time.

Given: P= $61,000, r= 1.9% =0.019 , A = $ 73600

Substitute all values in formula

$73600=61000e^{0.019t}\\\\\Rightarrow\ \dfrac{73600}{61000}=e^{0.019t}\\\\\Rightarrow\ 1.20655738=e^{0.019t}$

Taking natural log on both sides

$\ln (1.20655738)=0.019t\\\\\\ 0.18777116=0.019t\\\\\\ t=\dfrac{0.18777116}{0.019}\\\\\\ t=9.88269263\approx9.9\ \text{years}$

Hence, the required time = 9.9 years.

What does the problem want:

$\hookrightarrow \text{the unemployment compensation}$

Employment compensation =55% of the average of the last 26-week salary

$\hookrightarrow \text{Average of Natalia's salary} = (\text{all the salaries added up}) / (\text{number of weeks})\\\hookrightarrow \text{Average of Natalia's salary} = 18940 / 26 = 728.46 \text{ (Rounded down)}$

⇒ 55% of that average

$\hookrightarrow \frac{55}{100} *728.46 = 400.65$

Answer: $400.65
