Bet u can’t solve this

S_A_V [24]

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.

0.07 is 10 times as much as 0.007.

Because is means equal in mathematics
times means multiplication

so we can make:

0.07 = 10x
x = 0.007
