I don't know why they haven't taught me this yet!  Thanks to both of you!

E=hv, where h is Planck's constant, v is the frequency

E=(6.63 X 10^-34) X (7.91 X 10^10)

E=5.24433 X 10^-23, Joules-the energy of a single photon.

Thank You 

Could you provide the method of the answer

 0.56586 = 0.94^x, Very good, so far.

 0.56586 = 0.94^x, now, will take the log of both sides:

-0.24728=x * -0.02687, we divide bothe sides by -0.02687,

x=9.20282(rounded)

You'll need to use logarithms. I'm going to assume they're a new concept for you.

They're a bit like the opposite of exponents.

Logarithms can rearrange an exponent as shown below.

\(b=a^x\)

\(log_ab=x\)

This would be log base a of b equals x

You may have seen a "log" button on a calculator (the one on this website in fact!), and that's what we use to solve these equations.

So for your question, it would be.

\(0.56586=0.94^x\)

\(log_{0.94}0.56586=x\)

So x is equal to 9.2025.

Calculators can be a little funny when trying to change the log base. If there is no option for the log base, it will be log base 10.

why is -1 to the 10th positive

Because 10 is an EVEN number. If it were ODD number-like 11-then the answer would be negative.

it's 25,000,000,000,000

1- 30 mcg/dL       =3×10^-7 dL  (deciliters)

2- 18 pg/mL         =1.8×10^-11 mL  (milliliters)

3- 1 mg/dL           =1×10^-5 dL  (deciliters)

4- 3 ng/mL           =3×10^-9 mL  (milliliters)

5- 150 mg/dL       =0.0015 dL  (deciliters)

I couldn't find a

show work plz

What is your problem

Thank you very much 

I'm guessing you want to simplify this. You can treat the "<" as an equal sign and apply basic algebra unless you multiply by -1.

\(4a+4<12a\)

minus 4a from each side

\(4<8a\)

divide by 8

\(0.5<a\)

"a" must be greater than one half.

it's 19

4 is your answer

it equals 4

Yeah

the closest estimate would be 60

    When the fish is first dropped, it has kinetic AND potential energy.   When the fish smacks the ground it will have only kinetic energy.

Kinetic energy = 1/2 mv^2      Potential energy = m g h           where  m = mass  v = velocity  g =accel of gravity (9.8 m/s-s) and h= height

Does that help you get started?

Divide miles by hours, which will give you MPH.
