Answer:

Step-by-step explanation:

Assuming you're solving for p:

m=2^{-1} *2^p(2^p-1)

Let y=2^p

Now we can re-write the equation with y instead of 2^p.

m=\frac{1}{2} y(y-1)

2m=y^2-y

y^2-y-2m=0

Use the quadratic formula to get:

y = \frac{1+\sqrt{1+8m} }{2}

or

y = \frac{1-\sqrt{1+8m} }{2}

Therefore, using natural log and log rules:

2^p = \frac{1+\sqrt{1+8m} }{2}, ln(2^p)= ln(\frac{1+\sqrt{1+8m} }{2}),pln(2) = ln(\frac{1+\sqrt{1+8m} }{2}), p = \frac{ln(\frac{1+\sqrt{1+8m} }{2})}{ln(2)}

or

2^p = \frac{1-\sqrt{1+8m} }{2}, ln(2^p)= ln(\frac{1-\sqrt{1+8m} }{2}), pln(2) = ln(\frac{1-\sqrt{1+8m} }{2}), p = \frac{ln(\frac{1-\sqrt{1+8m} }{2})}{ln(2)}

If I haven't made any mistakes this should be correct!

Find the annual interest rate
patriot [66]

The annual interest rate is 6.2%.

Solution:

Given data:

Interest = $310

Principle = $1000

Time = 5 years

To find the annual interest rate:

<u>Simple Interest formula:</u>

$S.I=\frac{PRT}{100}

Substitute the given values in the formula, we get

$310=\frac{1000\times R \times5}{100}

Do cross multiplication.

$310 \times 100=1000\times R \times5

Divide both sides of the equation by 1000, we get

$\frac{310 \times 100}{1000}=\frac{1000\times R \times5}{1000}

31=R\times 5

Divide by 5 on both sides of the equation, we get

$\frac{31}{5}=\frac{R\times 5}{5}

6.2=R

R = 6.2%

Hence the annual interest rate is 6.2%.

Im kinda confused ;-;​
Ivan

Answer:

42-38

42 + (-38)

-38+42

Step-by-step explanation:

In all of these expressions, the 38 has to be negative because that is what you're taking away from the 48. When you have -(- it turns into a +.

In -42 + 38 the 42 is negative, but that is Emma's total amount so it's positive

With -42 -(-38) they did the just added those two together which would make the 42 still negative and the 38 positive.

THen with 42 + 38 the 38 is being subtracted from what she has so you would not add 38 to her total.
