Answer:
0.007502795
Step-by-step explanation:
We have
N = 10,000
Replacing these values in the expression for k:
So, the intensity is given by the function
The <em>total light intensity</em> is then
Since 
is an <em>even function</em>
and we only have to divide the interval ![\bf [0,10^{-6}]](https://tex.z-dn.net/?f=%20%5Cbf%20%5B0%2C10%5E%7B-6%7D%5D)
in five equal sub-intervals 
with midpoints 
The sub-intervals and their midpoints are
![\bf I_1=[0,\frac{10^{-6}}{5}]\;,m_1=10^{-5}\\I_2=[\frac{10^{-6}}{5},2\frac{10^{-6}}{5}]\;,m_2=3*10^{-5}\\I_3=[2\frac{10^{-6}}{5},3\frac{10^{-6}}{5}]\;,m_3=5*10^{-5}\\I_4=[3\frac{10^{-6}}{5},4\frac{10^{-6}}{5}]\;,m_4=7*10^{-5}\\I_5=[4\frac{10^{-6}}{5},10^{-6}]\;,m_5=9*10^{-5}](https://tex.z-dn.net/?f=%20%5Cbf%20I_1%3D%5B0%2C%5Cfrac%7B10%5E%7B-6%7D%7D%7B5%7D%5D%5C%3B%2Cm_1%3D10%5E%7B-5%7D%5C%5CI_2%3D%5B%5Cfrac%7B10%5E%7B-6%7D%7D%7B5%7D%2C2%5Cfrac%7B10%5E%7B-6%7D%7D%7B5%7D%5D%5C%3B%2Cm_2%3D3%2A10%5E%7B-5%7D%5C%5CI_3%3D%5B2%5Cfrac%7B10%5E%7B-6%7D%7D%7B5%7D%2C3%5Cfrac%7B10%5E%7B-6%7D%7D%7B5%7D%5D%5C%3B%2Cm_3%3D5%2A10%5E%7B-5%7D%5C%5CI_4%3D%5B3%5Cfrac%7B10%5E%7B-6%7D%7D%7B5%7D%2C4%5Cfrac%7B10%5E%7B-6%7D%7D%7B5%7D%5D%5C%3B%2Cm_4%3D7%2A10%5E%7B-5%7D%5C%5CI_5%3D%5B4%5Cfrac%7B10%5E%7B-6%7D%7D%7B5%7D%2C10%5E%7B-6%7D%5D%5C%3B%2Cm_5%3D9%2A10%5E%7B-5%7D)
<em>By the midpoint rule</em>
![\bf \int_{0}^{10^{-6}}I(\theta)d\theta\approx\frac{10^{-6}}{5}[I(m_1)+I(m_2)+...+I(m_5)]](https://tex.z-dn.net/?f=%20%5Cbf%20%5Cint_%7B0%7D%5E%7B10%5E%7B-6%7D%7DI%28%5Ctheta%29d%5Ctheta%5Capprox%5Cfrac%7B10%5E%7B-6%7D%7D%7B5%7D%5BI%28m_1%29%2BI%28m_2%29%2B...%2BI%28m_5%29%5D)
computing the values of I:
Similarly with the help of a calculator or spreadsheet we find
and we have
![\bf \int_{0}^{10^{-6}}I(\theta)d\theta\approx\frac{10^{-6}}{5}[I(m_1)+I(m_2)+...+I(m_5)]=\frac{10^{-6}}{5}(18756.98654)=0.003751395](https://tex.z-dn.net/?f=%20%5Cbf%20%5Cint_%7B0%7D%5E%7B10%5E%7B-6%7D%7DI%28%5Ctheta%29d%5Ctheta%5Capprox%5Cfrac%7B10%5E%7B-6%7D%7D%7B5%7D%5BI%28m_1%29%2BI%28m_2%29%2B...%2BI%28m_5%29%5D%3D%5Cfrac%7B10%5E%7B-6%7D%7D%7B5%7D%2818756.98654%29%3D0.003751395)
Finally the the total light intensity
would be 2*0.003751395 = 0.007502795
Answer:
51
Step-by-step explanation:
10 + (25 + 16)
10 + 41
=51
Answer: 1) Product property of logarithm,
2) Subtraction property of logarithm
3) Equality property of logarithm
Step-by-step explanation:
By the Product property of logarithm,
log a + log b = log(a.b)
And, By the Subtraction property of logarithm
log a - log b = log(a/b)
Also, by the equality property of logarithm,
log(a) = log(b) ⇒ a = b
Given expression,
(Product property of logarithm)
(Subtraction property of logarithm)
( Equality property of logarithm )
( Multiplicative property of equality )
( Distributive property of equality )
(subtraction property of equality )
(division property of equality )
Answer:
2
Step-by-step explanation:
how many numbers are to the right of the decimal point? that would be 2 :)
6 1/2 = 6.5
1 3/4 = 1.75
6.5/1.75=3.7
there was 3.7 inches per hour.
