?
Mathematics
1 answer:
ivolga24 [154]3 years ago
5 0

Answer:

V = 5000 +  275*T   for simple annual interest

or:   A = 5000 * (1.055)^T   for an annual compound interest

Step-by-step explanation:

I assume this is a simple interest rate.  If not I will give the one for compound interest.

V = 5000 + 5000* 0.055 * T      (Value of account after T years)

V = 5000 +  275*T   for simple annual interest

or:   A = 5000 * (1.055)^T   for an annual compound interest

chubhunter [2.5K]

we know that

Francine uses 2/3 cup of pineapple juice for every 1/3 cup of orange juice to make a smoothie

so

by proportion

Find the number of cups of pineapple for one cup of orange juice

\frac{(2/3)}{(1/3)} \frac{cups\ pineapple}{cups\ orange} =\frac{x}{1} \frac{cups\ pineapple}{cups\ orange}\\ \\x*(1/3)=(2/3) \\ \\x=2\ cups\ pineapple

therefore

<u>the answer is</u>

2\ cups\ pineapple\ juice

A beam of light from a monochromatic laser shines into a piece of glass. The glass has thickness L and index of refraction n=1.5
boyakko [2]

Additional information to complete the question:

How long does it take for a short pulse of light to travel from one end of the glass to the other?

Express your answer in terms of some or all of the variables f and L. Use the numeric value given for n in the introduction.

T = ___________ s

Answer:

 T = \frac{15}{f}

Step-by-step explanation:

Given:

Thickness og glass = L

Index of refraction n=1.5

Frequency = f

Wavelength = \frac{L}{10}

λ(air) = \frac{L}{10}

λ(glass) = λ(air) / n

             = \frac{\frac{L}{10}}{1.5}

             = \frac{L}{10} * \frac{1}{1.5}

             = \frac{L}{15}

V(glass) = fλ(glass)

              = f * \frac{L}{15}

          T = \frac{L}{V_{glass}} = \frac{15}{f}
