Answer:

Correct [nearly]

Step-by-step explanation:

<em>s</em> = 4<em>p</em> + 4<em>q</em>

-4<em>p</em> - 4<em>p</em>

___________

-4<em>p</em> + <em>s</em><em> </em>= 4<em>q</em>

_______ ___

4 4

$- p + \frac{s}{4} = q$

This answer choice was not quite done with simplification yet, as you can see.

I am joyous to assist you anytime.

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!

During a biology course, Jacobi learned that the diameter of red blood cells can be written as 6.5x10 to the -3 power millimeter

madreJ [45]

Answer:

$\bold{0.0065}$

Step-by-step explanation:

Hi there!

Let's convert numbers in scientific notation to standard form.

$\bold{6.5x10^{-3} }$ => scientific notation

First, the coefficient is $\bold{6.5}$ .

So, we know part of our number.

Now, let's look at the exponent:

$\bold{-3}$

First of all, the exponent is $\bold{NEGATIVE}$ .

This means that we'll move the decimal point to the $\bold{left}$ .

Then, the 3 means we'll move the decimal point 3 units.

So, our number looks like so:

$\bold{0.0065}$

Hope it helps! Enjoy your day!

mihalych1998 [28]

Answer: If there are 35 people going and each ticket cost $20, then it would be 35 x 20

Step-by-step explanation:

People going: 35

Cost for each person: $20

35 x $20 = 700

So the total cost of tickets for 35 people would be <u>$700</u>.
