Texaschic nailed it when saying that it's arithmetic

The recursive way to write this is to say

a_1 = 6
a_n = a_{n-1} - 5

which tells us "start at 6 and each time subtract off 5"

The a_n portion is the nth term while a_{n-1} is the term just before the nth term

Find a cubic polynomial in standard form with real​ coefficients, having the zeros 4 and 5i. Let the leading coefficient be 1.
SCORPION-xisa [38]
If one of our zeros is 4, then the factor is x-4.  If the second zero is 5i, then the conjugate root theorem says there HAS to be a root that is -5i.  So our 3 factors are (x-4)(x+5i)(x-5i).  We will FOIL out these factors to get the polynomial.  Let's start with the ones that contain the imaginary numbers.  Doing that mutliplication we get x^2-25i^2.  i^2 is equal to -1, so what that expression simplifies down to is x^{2} +25.  Now we will multiply in that last factor of (x-4):  (x^2+25)(x-4).  FOILing out we have x^3-4x^2+25x-100.  There you go!

A rancher’s herd of 250 sheep grazes over a 40-acre pasture. He would like to find out how many sheep are grazing on each acre o
Bess [88]

Answer:

6

Step-by-step explanation:

So to find how much sheep there were on each acre, you divide.

250/40

You do this because you are splitting the 250 sheep into 40 acres.

250/40 = 6.25

There cannot be .25 of a sheep, and since it says on average the answer does not need to be exact. So you would round it off to 6 as your answer.

How many terms are there in the following expression? x - 5 + 16x + 4 - 2x - 3
k0ka [10]

Answer:

Two terms

Step-by-step explanation:

First, we have to simplify reducing the number of terms, since there are like terms

x-5+16x+4-2x-3

Eventually, you'll get 15x-4,  thus there are two terms.

Please correct me if I'm incorrect, and I'll change the answer, but I hope I helped :)
