How long does it take $450 to double at simple interest rate of 100%

1 answer:

8 0

Depending on when you get your interest rate. but it will double the second you get your interest rate, because it is a 100% interest

hope this helps

(it can be daily, weekly, monthly, etc)

D + 3n = 1 Subtract d from both sides
3n = 1 - d Divide both sides by 3
n = $\frac{1 - d}{3}$

When plucked, the high E string on a guitar has a frequency of 330 cycles per second. What sine function represents this note wh

Ber [7]

Let's analyse the function

$y = f(x) = A\sin(\omega x)$

The amplitude is A, so we want A=1.5

Now, we start at x=0, and we have $1.5\sin(0)=0$

After one second, i.e. x=1, we want this sine function to make 330 cycles, i.e. the argument must be $330\cdot 2\pi$

So, we have

$f(1)=1.5\sin(\omega) = 1.5\sin(660\pi)$

so, the function is

$f(x) = 1.5\sin(660\pi x)$

Answer:

D. y+15 = 4/5(x+5)

Step-by-step explanation:

A line contains the points (8,9) and (-12, -7).

(y2 - y1) = m(x2 - x1)

(9 - (-7))= m (8 -(-12))

16 = m*20

m = 16/20 = 4/5

Given line has slope m= 4/5.

Parallel line has the same slope m = 4/5.

Point-slope equation is (y - y1) = m(x - x1).

We have slope m = 4/5, and point (-5, -15).

So,

(y - (-15)) = 4/5(x - (-5))

y+15 = 4/5(x+5)
