You stand a known distance from the base of the tree, measure the angle of elevation the top of the tree to be 15â—¦ , and then
gogolik [260]

Answer:

The maximum possible error of in measurement of the angle is  d\theta_1  =(14.36p)^o

Step-by-step explanation:

From the question we are told that

    The angle of elevation  is  \theta_1  =  15 ^o =  \frac{\pi}{12}

     The height of the tree is  h

      The distance from the base is  D

h is mathematically represented as

            h  = D tan \theta       Note : this evaluated using SOHCAHTOA i,e

                                               tan\theta  =  \frac{h}{D}

Generally for small angles the series approximation of  tan \theta \  is

          tan \theta  =  \theta  + \frac{\theta ^3 }{3}

So given that \theta =  15 \ which \ is \ small

       h = D (\theta + \frac{\theta^3}{3} )

       dh = D (1 + \theta^2) d\theta

=>        \frac{dh}{h} =  \frac{1 + \theta ^2}{\theta + \frac{\theta^3}{3} } d \theta

Now from the question the relative error of height should be at  most

        \pm  p%

=>    \frac{dh}{h} =   \pm p

=>    \frac{1 + \theta ^2}{\theta + \frac{\theta^3}{3} } d \theta  = \pm p

=>      d\theta  =  \pm  \frac{\theta +  \frac{\theta^3}{3} }{1+ \theta ^2} *    \ p

 So  for   \theta_1

            d\theta_1  =  \pm  \frac{\theta_1 +  \frac{\theta^3_1 }{3} }{1+ \theta_1 ^2} *    \ p

substituting values  

          d [\frac{\pi}{12} ]  =  \pm  \frac{[\frac{\pi}{12} ] +  \frac{[\frac{\pi}{12} ]^3 }{3} }{1+ [\frac{\pi}{12} ] ^2} *    \ p

 =>       d\theta_1  = 0.25 p

Converting to degree

           d\theta_1  = (0.25* 57.29) p

            d\theta_1  =(14.36p)^o

Enter the explicit rule for the geometric sequence.
Sveta_85 [38]

Answer:  \frac{3}{2}(\frac{1}{2})^{n-1}

<u>Step-by-step explanation:</u>

\frac{3}{2}, \frac{3}{4}, \frac{3}{8}, \frac{3}{16}, \frac{3}{32}, ...

common ratio (r) = \frac{1}{2}

first term (a₁) = \frac{3}{2}

a_{n} = a₁ (r)ⁿ⁻¹

   = \frac{3}{2}(\frac{1}{2})^{n-1}

3 more than the product of 7 and a number x is less than 26 Find the solution set for x. Write the solution using a fraction or
Tresset [83]

Answer: The solution set is x\:


Step-by-step explanation:


The product of 7 and x is 7x.


3 more than the product of 7 and x is 7x+3.



We were given that, the expression is less than 26.


This implies that,


7x+3\:.



We group like terms to obtain,



7x\:



7x\: we now divide through by 7 to obtain,


x\:


We finally write this as a mixed number to obtain,


x\:
