\bf (\stackrel{r}{0},\stackrel{\theta }{0^o})\qquad \quad 0=2-3cos(0^o)\implies 0=2-3(1)\implies 0\ne -1
\\\\\\
(\stackrel{r}{1},\stackrel{\theta }{0^o})\qquad \quad 1=2-3cos(0^o)\implies 1=2-3(1)\implies 1\ne -1
\\\\\\
(\stackrel{r}{2},\stackrel{\theta }{0^o})\qquad \quad 2=2-3cos(0^o)\implies 2=2-3(1)\implies 2\ne -1
\\\\\\
(\stackrel{r}{-1},\stackrel{\theta }{0^o})\quad \quad -1=2-3cos(0^o)\implies -1=2-3(1)\implies -1=-1

COS Find the quotient when the polynomial expression is divided by a binomial Find the quotient ANSWER SOLUTION CHOICES X2+11x+
ryzh [129]

Answer:

x=−1 or x=−9

Step-by-step explanation:

x2+11x+10=x+1

Step 1: Subtract x+1 from both sides.

x2+11x+10−(x+1)=x+1−(x+1)

x2+10x+9=0

Step 2: Factor left side of equation.

(x+1)(x+9)=0

Step 3: Set factors equal to 0.

x+1=0 or x+9=0

x=−1 or x=−9

-2w(w+8) what is the answer
Julli [10]
-2w (w + 8)
 Assuming that it is a polynomial from which you must find the roots, we must first rewrite it:
 -2w (w + 8) = 0
 The roots are then:
 w1 = 0
 w2 = -8
 Assuming you only have to rewrite the expression, the answer is:
 -2w ^ 2 -16w
 Answer:
 w1 = 0 
 w2 = -8
 -2w ^ 2 -16w

Write a linear function ff with f(4)=−3f(4)=−3 and f(0)=−2f(0)=−2
Nonamiya [84]
<span>The line goes through the points (4,-3) and (0,-2), so its gradient is (-2-(-3))/(0-4) = -1/4. The y-intercept is -2 because f(0)=-2. So the equation of the line is y = -1/4 x - 2.This can be represented by the linear function f(x) = (-1/4)x - 2. The composite function ff is given by ff(x) = f(-1/4 x - 2) = (-1/4)((-1/4)x - 2) - 2 = x/16 - 3/2.</span>

asambeis [7]

Split the second term 7x^2 - 8x - 12 into two terms

7x^2 + 6x - 14x - 12

Factor out common terms in the first two terms, then in the last two terms

x(7x + 6) - 2(7x + 6)

Factor out the common term; 7x + 6

<u>(7x + 6)(x - 2) </u>
