Answer:
5.131 × 10¹⁴ Hz
Step-by-step explanation:
<u>Planck relation</u>
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:
First you need to find the cicumfrence of the circle which is π × r (radius) or π × c (circumfrance) ÷ 2
So, 1725 would be 1 and a half month's pay of rent.
The equation would be 1725 divided by 1.5 since that would get us what the two friends paid for one month of rent. Let r= rent.
1725/1.5= r
1725/1.5= 1150
So, rent would equal $1150.
I hope this helps!

We see all of them have 2 and 0.5
so therfor b+c=-2.5
so
remember
a(b+c)=ab+ac
so
8.6(-2-0.5)=8.6(-2)+8.6(-0.5)
last option
