100 POINTS PLS HELP !!! A star becomes twice as bright every 10 years

Mathematics

Answer:

Step-by-step explanation:

"Twice" as bright can translate into the mathematical expression "times 2", where for every year, you multiply the previous year's brightness by 2.

Since this is a rate (using multiplication) and not a common difference (not using addition), it must be an exponential <em>something</em>, so eliminate C.

Now, since 2 > 1, that means this is an exponential growth. Remember that if the rate r is less than 1, then it's decay; if r is greater than 1, then it's growth.

The answer is thus A.

2.3,2 4/5, 2.6 from least to greatest

Alex777 [14]

Hello there!

Least to greatest of these problem

For the fractions you can simplify it make it easier for you to solve these types of problems

Anyhow!

Let's find our answer, shall we?

$2.3 = 2.3 \\ \\ 2\frac{4}{5} = \frac{14}{5} = 2.8 \\ \\ 2.6 = 2.6$

Our answer: $2.3 \\ 2.6 \\ 2\frac{4}{5}$

What is the frequency of yellow

Zina [86]

Answer:

5.131 × 10¹⁴ Hz

Step-by-step explanation:

<u>Planck relation</u>

$\large\boxed{E = hf}$

where:

E = Energy of the photon (J).
h = Planck's constant (J · s).
f = frequency of light produced (Hz).

Given values:

E = 3.4 × 10⁻¹⁹ J
h = 6.626 × 10⁻³⁴ J · s

Substitute the given values into the formula and solve for f:

$\implies 3.4 \times 10^{-19}=(6.626 \times 10^{-34})f$

$\implies f=\dfrac{3.4 \times 10^{-19}}{6.626 \times 10^{-34}}$

$\implies f=\dfrac{3.4}{6.626} \times \dfrac{10^{-19}}{10^{-34}}$

$\implies f=0.5131\times 10^{(-19-(-34))}$

$\implies f=0.5131 \times 10^{15}$

$\implies f=5.131 \times 10^{14}$

What is the angle measurement shown?

4vir4ik [10]

Answer:

The answer is A.

Step-by-step explanation:

When the Protractor is held up to the angle, you can see that the rays form an Obtuse angle. Looking at the point where the ray intercepts the curved part of the protractor, the number it goes through is 100⁰ ( ¨ ⁰ ¨ means ¨degrees¨).

Answer:

The GREATER the line the STEEPER the PROPORTIONALITY of X you know you have a constant proportionality when your graph begins at the ORIGIN we can write the equation as y = K x. We find the constant of proportionality by DIVIDING the CONSTANT coordinate by the Y coordinate from an ordered pair.

Step-by-step explanation:

I think I'm not sure you should probably get a second opinion to be sure.
