Answer:

  6.3 years

Step-by-step explanation:

The growth factor each year is 1+19% = 1.19. You want to find the number of years (t) that result in a multiplier of 3 for the account value:

  3 = 1.19^t

Taking logarithms, you get ...

  log(3) = t·log(1.19)

  log(3)/log(1.19) = t ≈ 6.32

It will take a little more than 6 years for Casey/Brad's investment to triple in value.

What precent of 95 is 60.8​
dezoksy [38]

60.8 is 64% of 95.

Step-by-step explanation:

Given number is;

95

We have to find at what percent, the value is 60.8

Let x be the percent.

Therefore;

x% of 95 = 60.8

\frac{95x}{100}=60.8 \\0.95x=60.8

Dividing both sides by 0.95

\frac{0.95x}{0.95}=\frac{60.8}{0.95}\\x=64

60.8 is 64% of 95.

Keywords: percent, division

Use a graphing calculator to solve the equation -2sin(theta)= 1.2 in the interval from 0 to 2pi.
elena-s [515]

Answer:

\theta=\pi +arcsin(\frac{3}{5})\approx 3.785\\\\\theta=2\pi -arcsin(\frac{3}{5} ) \approx 5.64  

Step-by-step explanation:

As you can see from the graph I attached you, the possible solutions in the interval from 0 to 2π are approximately:

\theta=3.7\\\\and\\\\\theta=5.7

So, it's useful to solve the equation too, in order to verify the result:

-2sin(\theta)=1.2\\\\sin(\theta)=-\frac{3}{5}

Taking the inverse sine of both sides:

\theta=\pi +arcsin(\frac{3}{5})\approx 3.785\\\\\theta=2\pi -arcsin(\frac{3}{5} ) \approx 5.64

Using this result we can conclude the solutions in the interval from 0 to 2π are approximately:

\theta\approx 3.785\\\\\theta \approx 5.64
