Answer:

k=0.106383

Step-by-step explanation:

Let's solve your equation step-by-step.

12=4.7k+11.5

Step 1: Flip the equation.

4.7k+11.5=12

Step 2: Subtract 11.5 from both sides.

4.7k+11.5−11.5=12−11.5

4.7k=0.5

Step 3: Divide both sides by 4.7.

4.7k

4.7

=

0.5

4.7

k=0.106383

Enter the number that makes the equation true.<br><br> 0.26 - 41/100 = blank/100 - 41/100
Lerok [7]
Note that you are subtracting the same number from both sides. Thus, blank/100 must equal .26. Convert .26 to a fraction by placing it over 100 and removing the decimal point: 26/100. blank = 26

Given the function defined below, what is the value of the 4th term?
MakcuM [25]

Answer:

The 4 t h term is   f(4)   = 143

Step-by-step explanation:

<em>Explanation</em>:-

Given  function f(1) = -4

Given 'nth' term is  f(n) = -3f(n-1) +5

Put n =2         <em> f(2) = -3 f(2-1) +5</em>

                             = -3 f(1) +5

                             = -3 (-4) +5

                             = 12 +5

                       f(2) = 17

put n= 3      

                         f(n) = -3f(n-1) +5  

                      <em>   f(3) = -3 f(3-1) +5</em>

                            = -3f(2) +5

                           = -3(17) +5

                           = -51+5

                      f(3) = -46

Put n=4

                  f(n) = -3f(n-1) +5

               <em>  f(4)  = -3f(4-1) +5</em>

<em>                  f(4)  = -3f(3)+5</em>

                f(4)   = -3(-46)+5

                f(4)   = 138 +5

                f(4)   = 143

<u><em>Final answer</em></u>:-

<em>The 4 t h term is   f(4)   = 143</em>
