Given f(x)=2x^2+9x+k, and the remainder when f(x) is divided x+7 is 32, then what is the value of k?
sweet-ann [11.9K]

Set up either long division or synthetic div.  I'd do the latter.

Your divisor for synth. div. should be -7.

                           __________  
Then              -7 /  2      9      k
                                    -14   +35
                          --------------------
                             2      -5      k+35                 Rem is 32; 
                                                                     Let 32 = k + 5 and solve for k:

                                                                           k = -3.

Let's check that.  Is k correct?

Then              -7 /  2      9      -3
                                    -14   +35
                          --------------------
                             2      -5      -3+35  = 32

Since the rem is 32, we are correct; k = -3.

To write the explicit rule, we need some information about the following series:
Maslowich

Answer:

see explanation

Step-by-step explanation:

Note the common ratio r between consecutive terms of the sequence

r = 6 ÷ 3 = 12 ÷ 6 = 24 ÷ 12 = 48 ÷ 24 = 2

The explicit rule for a geometric sequence is

a_{n} = a₁(r)^{n-1}

where a₁ is the first term and r the common ratio

Here a₁ = 3 and r = 2, thus

a_{n} = 3(2)^{n-1} ← explicit rule
