</span><span>Principal = 35,000 / [1.08]^4
</span><span><span><span>Principal = 35,000 / 1.36048896 </span> </span> </span>
Principal = <span> <span> <span> 25,726.04 </span> </span> </span>
So, you would have to deposit $25,762.04 @ 8 per cent to have 35,000 in four years.

Suppose you have a water-balloon launcher. The balloon is 3 ft high when it leaves the launcher. Use the equation 0 = ?16t2 + 38
mario62 [17]

Answer:

t = 2.5 s

Step-by-step explanation:

Suppose you have a water-balloon launcher. The balloon is 3 ft high when it leaves the launcher. Its equation is :

16t^2 + 38.8t + 3 =0

The above equation is a quadratic equation. The general equation is :

ax^2+bx+c=0

Here, a = 16, b = 38.8 and c = 3

The solution of quadratic equation is given by :

x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}\\\\t=\dfrac{-38.8\pm \sqrt{(38.8)^2-4\times (-16)\times 3} }{2\times (-16)}\\\\t=\dfrac{-38.8+\sqrt{(38.8)^{2}-4\times-16\times3}}{-2\times16}, \dfrac{-38.8-\sqrt{(38.8)^{2}-4\times-16\times3}}{-2\times16}\\\\t=-0.075\ s,2.5\ s

So, at t = 2.5 s the balloon is in air.

4. A 16-piece orchestra wants to choose one
pishuonlain [190]

Answer:

1/12

Step-by-step explanation:

subtract the four soloists who can't be chosen from the total musicians

16-4=12

Itzhak is one person out of 12 who could be chosen to speak

Also the question is annoying because nobody calls an orchestra with 16 people a "16 piece orchestra"
