Laura deposits $2,000 in an account that has an annual interest rate of 1.96%,
galben [10]

Answer:

$3.23

Step-by-step explanation:

Given that,

Principal, P = $2,000

Rate of interest, r = 1.96%

Tie, n = 1 month = (1/12) years

The formula of compound interest is given by :

CI=P[(1+\dfrac{R}{100})^n-1]\\\\CI=2000\times [(1+\dfrac{1.96}{100})^{1/12}-1]\\\\CI=3.23

So, the interest will she earn at the end of 1 month is $3.23

A certain forest covers an area of 4000km^2. Suppose that each year this area decreases by 3.5%. What will the area be after 9 y
kaheart [24]
Simply will say
4000(3.5%) = 140 km^2
So each year will decrease by 140km^2
To find till 9th years it will be
4000-(140*9)=2740 km^2
Area after 9 years is 2740 km^2

"A clock is positioned on an auditorium wall with its center 9 feet above the floor. The second hand is 10 inches long and conti
GenaCL600 [577]

Answer: f(x) = 10in*cos(x*2*pi/60s) + 10in*sin(x*2*pi/60s) + 108in.

Step-by-step explanation:

When we have a circular motion, we can write this as:

f(x) = A*sin(k*x + f) + A*cos(k*x + f) + C.

where:

k is a constant that depends on the period.

f is a phase shift.

C is the mean height of the circular motion, in this case will be equal to the height of the center, that is 9ft.

C = 9ft.

A is the amplitude of the motion, in this case is equal to the radius, that is equal to the lenght of the second hand

A = 10in

But we should write both quantities in the same units, so we have:

1ft = 12in

then:

C = 9ft = 9*12in = 108in

Then our equation is:

f(x) = 10in*cos(k*x + f) + 10in*sin(k*x + f) + 108in

now, x = 0s coincides with the noon

so at x = 0s, the second hand is pointint to the twelve, this means that is in the max height, so we have:

F(0s) = 10in*cos(0 + f) + 10in*sin(0 + f) + 108 in

Now, the maximum value will be when the value inside the sinusoidals is 0.

(because cos(0) = 1 and sin(0) = 0)

then we have that f = 0.

Now, we know that it takes 60 seconds to do a full revolution, and for the sinusodial functions the period is 2*pi

Then we have:

c*60s = 2*pi

c = 2*pi/60s.

Then the equation is:

f(x) = 10in*cos(x*2*pi/60s) + 10in*sin(x*2*pi/60s) + 108in.

MariettaO [177]

The average daily balance after 20 days is; $1750

<h3>Average Balance</h3>

The initial balance after grace period is; $25,000

Afterwards, A payment of $5,000 each is made on the 10th and 20th day.

Hence, the total balance after 20 days is;

  • = $25,000 + $5000 + $5000

  • = $35,000.

The average daily balance is therefore the quotient of $35,000 and 20 days

  • The average daily balance = $35,000/20

  • Average daily balance = $1750
