using compound interest, how long does it take to double a 1000 dollar investment that pays 6.5% annual interest, compounded monthly?​

Answers

Answer 1

Answer:

11 years approx

Step-by-step explanation:

Given data

P=$1000

A=2000

R=6.5%

T= ?

Calculate time, solve for t

t = ln(A/P) / r

substitute

t=ln(2000/1000)/0.065

t=ln(2)/0.065

t=0.693/0.065

t=10.66

Hence the time is 11 years approx

Help me please

Answers

Answer:

The answer is 12

Step-by-step explanation:

36/9=4

4x3=12

So first you would divide 12 in half to figure out how many inches it moves in 24 hours (or 1 day) which would be 6 inches every 24 hours. You then multiply 6 (inches per day) by 7 (# of days). You end up with 42 inches in 7 days. Hope this helps

Find the value of m.
28
(10m - 30)
Enter your answer with one decimal place.

Answers

(10m-30) = 28. 28 plus 30 is 58 and 58/10 is 5.8. M is 5.8.
28 = 10m - 30

28 + 30 = 10m

58 = 10m

10m = 58

m = 58/10

m = 5.8

3(5p - 1) - 4(3p - 7)
Also please explain it as well

Answers

Answer:

3p + 25

Step-by-step explanation:

Let's start with the original expression:

3(5p – 1) – 4(3p – 7)

We need to distribute each constant to the binomial they are multiplying, and when we do that, we get:

15p – 3 – 12p + 28

Why did the 28 turn out positive? We multiplied two negative numbers together, –4 and –7 , and multiplying two negatives always gives us a positive product.

Now, let's rewrite the expression to group like terms together:

15p – 3 – 12p + 28  — marked like terms, constants bold, variables underlined

15p – 12p + 28 – 3  — rewrote the expression to group like terms

Finally, we combine each set of like terms together to get our final answer:

3p + 25  — simplifying

Hope this helps you understand the concept! Have a great day!

3p+25 you just have to distribute and then collect like terms

Solve the system of equations by substitution.
3/8x +1/3y=17/24
x+7y=8

Answers

Answer:

x=1, y=1.

Step-by-step explanation:

From the second equation:

x = 8 - 7y, so substituting for x in the first equation:

3/8(8 - 7y) + 1/3y = 17/24

3 - 21/8 y + 1/3y = 17/24

1/3y - 21/8y = 17/24 - 3

Multiply through by 24:

8y - 21*3 y = 17 - 72

8y - 63y = -55

-55y = -55

y = 1.

And  substituting for y in the second equation:

x + 7(1) = 8

x = 8 - 7

x =  1.

Use complete sentences to answer the following question.

1. Choose one of the properties of exponents (for example, the Power of a Power Rule). Explain how the property works, and provide an example of the property.

Answers

Answer:

Product of a Power: When you multiply exponentials with the same base, you add their exponents (or powers). Power to a Power: When you have a power to a power, you multiply the exponents (or powers). Quotient of Powers: When you divide exponentials with the same base, you subtract the exponents (or powers).

Step-by-step explanation:

Answer:

What is the Power rule?

The Power rule tells us how to differentiate expressions of the form x^nx

n

x, start superscript, n, end superscript (in other words, expressions with xxx raised to any power):

\dfrac{d}{dx}x^n=n\cdot x^{n-1}

dx

d

x

n

=n⋅x

n−1

start fraction, d, divided by, d, x, end fraction, x, start superscript, n, end superscript, equals, n, dot, x, start superscript, n, minus, 1, end superscript

Basically, you take the power and multiply it by the expression, then you reduce the power by 111.

Example: What is the derivative of x2 ?

For x2 we use the Power Rule with n=2:

The derivative of x2 = 2x(2-1)

= 2x1

= 2x

Answer: the derivative of x2 is 2x
