Answer:
The slope is m=2
Step-by-step explanation:
we have

This is the equation of a line in slope intercept form

where
m is the slope
b is the y-coordinate of the y-intercept
therefore
The slope m is equal to

<em>Alternative Method</em>
we know that
The formula to calculate the slope between two points is equal to
we have
and the domain {-1, 4}
For x=-1
point (-1,-7)
For x=4
point (4,3)
substitute the values in the formula of the slope
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
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:
$13.50
Step-by-step explanation:
You can use the simple interest formula here: I(interest)=P(principal amount)r(interest rate)t(years). I=Prt. So just plug in the numbers. I=90x.15x1=13.5

Answer:
60, 120, 180, 240, 300, 360
Step-by-step explanation:
a(n)=60n
At n =1
a(1) = 60(1) = 60
At n = 2
a(2) = 60(2) = 120
At n = 3
a(3) = 60(3) = 180
At n = 4
a(4) = 60(4) = 240
At n = 5
a(5) = 60(5) = 300
At n = 6
a(6) = 60(6) = 360
60, 120, 180, 240, 300, 360
