1) Let f(x) be x^3+5x^2+2x+1
Since f(x) is divided by x+1,
R= f(-1) = (-1)^3 + 5(-1)^2+2(-1) + 1
= -1+5-2+1
= 3
2) Let f(x) be x^3 - 6x + 5x +2
Since f(x) is divided by x-5,
R= f(5) = x^3 - 6x^2 + 5x +2
= 5^3 - 6(5)^2 + 5(5) +2
= 125 - 150 + 25 + 2
= 2

Answer:

Step-by-step explanation:

CD is Pole

∠CAD = 4°  {Alternate interior angles}

ΔCAD,

\dfrac{opposite \ side}{adjacent \ side}= tan 4\\\\ \dfrac{90}{AD}=tan \ 4\\\\ \dfrac{90}{AD} = 0.069\\\\90 = 0.069*AD\\\\ \dfrac{90}{0.069}=AD\\\\AD = 1304 \ ft

In ΔCDB,

∠B = 5° {Alternate interior angles}

Tan \ 5 = \dfrac{90}{BD}\\\\0.09* BD = 90\\\\BD =   \dfrac{90}{0.09}\\\\BD = 1000 \ ft

Serial numbers for a product are to be made using 3 letters followed by 4 digits. The letters are to be taken from the first let
Tpy6a [65]

Answer:

30,240 ways,  if I am restricted to using A, B, and C for letters

Step-by-step explanation:

This uses Combinatorics from Discrete Math.

so.

3 letters  and 4 digits.

26 letters from alphabet, but you want to choose first letters.  no repeats...

Does this mean only letters A, B, and C ?

digits from 10 digits...

I imagine  7 empty slots , and the number of ways they occur together is by the product of the number of choices each box has.

3*2*1  *  10*9*8*7 = 6  * 5040  = 30,240 ways
