Answer: $ 3446.7972 will be the balance of his account.

Step-by-step explanation:

Here the principle amount of the saving account, P = $ 3300

And, the Annual percentage of interest, r = 4.4%

Number of years = 1

Thus, the amount after getting semiannual compound interest is,

A = P (1+\frac{r/2}{100} )^2

⇒ A = 3300 (1+\frac{4.4/2}{100} )^2

⇒ A = 3300(1+\frac{2.2}{100} )^2

⇒ A = 3300(\frac{102.2}{100} )^2

⇒  A = 3300\times \frac{102.2}{100}\times \frac{102.2}{100}

⇒ A = 3300 × 1.022 × 1.022 = $ 3446.7972

Thus, the balance of his account after all the interest is paid for the year is $ 3446.7972

A ball is thrown downward from a cliff. Its position at time t seconds is given by the formula s(t) = 16t2 + 32t, where s is in
Rom4ik [11]

Answer:

It takes 2.8 seconds for the ball to fall 215 ft.

Step-by-step explanation:

We are given a position function s(t) where s stands for the number of feet the ball has fallen, so we have to replace s with the given value of 215 ft and solve for the time t.

Setting up the equation.

The motion equation is given by

s(t) =16t^2+32t

We can replace there s = 215 ft to get

215=16t^2+32t

Solving for the time t.

From the previous equation we can move all terms in one side to get

16t^2+32t-215=0

At this point we can solve for t using quadratic formula.

t = \cfrac{-b\pm \sqrt{b^2-4ac}}{2a}

where a, b and c are the coefficients of the quadratic equation

at^2+bt+c=0

So we get

a=16\\b=32\\c=-215

Replacing on the quadratic formula we get

t = \cfrac{-32\pm \sqrt{32^2-4(16)(-215)}}{2(16)}

Using a calculator we get

t=-4.8 , t = 2.8

Physically speaking the only result that makes sense is to move forward in time that give us t = 2.8 seconds.

We can conclude that it takes 2.8 seconds for the ball to fall 215 ft.
