The period of a function is the horizontal length of one complete cycle. The period may also be described as the distance from one "peak" (max) to the next "peak" (max). This sine curve, y = sin x, has a period of 2π, the horizontal length of one complete cycle.

The amount of money in a savings account increases from $250 to $270 in one month. If the percent increase is the same for every
Sergeu [11.5K]

Answer:

$291.60

Step-by-step explanation:

First figure out the percentage increase

270 - 250 = 20. This was the increase

Percentage increase = 20 / 250 x 100

= 8%

8% = 0.08

Money next month = 270 x 1.08 = $291.60

You need to have $20,000 for a down payment on a house 6 in years. If you can earn an annual interest rate of 4.2 percent, how m
Alexxandr [17]

Answer: you have to deposit $15625 today

Step-by-step explanation:

Assuming the interest is compounded annually. We would apply the formula for determining compound interest which is expressed as

A = P(1+r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

A = $20000

r = 4.2% = 4.2/100 = 0.042

n = 1 because it was compounded once in a year.

t = 6 years

Therefore,.

20000 = P(1 + 0.042/1)^1 × 6

20000 = P(1.042)^6

20000 = 1.28P

P = 20000/1.28

P = $15625

Simplify 9x^2 - 25/3x-5
satela [25.4K]
First, we are going to write it like this:
\frac{9x^2-25}{3x-5}
Then, we are going to do something like factoring, but it's not factoring. An example would be: x^2-y^2=\left(x+y\right)\left(x-y\right)
If we apply it, we would be left with:
=\frac{\left(3x+5\right)\left(3x-5\right)}{3x-5}
We cancel the common factors, and we are left with:
=3x+5
That's our final answer.

Let me know if you need any more help!
Thanks!
