Basically, you multiply 15 by each digit at the top of the long division symbol-thing. For example, the problem did 15x4 to get 60. Then the problem subtracted it from 6396. To get the answer for the box, just multiply 15x2, which is 30. If you need more help please just comment and I’ll gladly help you!

Two exponential functions are shown in the table. A 3-column table has 5 rows. The first column is labeled x with entries 2, 1,
DanielleElmas [232]

Answer:

B. The functions f(x) and g(x) are reflections over the y-axis.

Step-by-step explanation:

From the information given the table appears as;

x            f(x)=2^x              g(x)=0.5^x

2               4                            0.25

1                 2                           0.5

0                1                             1

-1                0.5                         2

-2               0.25                       4

Plotting the two graphs to view the trends;

In the graph of f(x)=2^x against x you notice a curve with increasing positive slope.

In the graph of g(x)=0.5^x against x you notice a curve with a negative slope that is increasing.

In combining both graphs you notice that f(x) and g(x) are reflections over the y-axis.

Correct answer is ;The functions f(x) and g(x) are reflections over the y-axis.

Evaluate 1/3 * 5/6 in fraction form
andreev551 [17]

Answer:

= 6 over 23 (or = 6/23

Step-by-step explanation:

Convert mixed numbers to improper fractions 3 5/6 = 23/6

Convert element to fraction

= 1 divide 23/6

Apply the fraction rule: a/b divide c/d = a/b x d/c

= 1 over 1 (or 1/1) divide 23/6

Apply rule a/a = 1

= 1 over 1 (or 1/1) x 6/23

Multiply 1x 6/23 = 6/23

= 1 x 6/23

ANSWER 6/23

Hope this helps!

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
