What is a equation that has a zero of -2 with a multiplicity of 3, a zero of 1 with a multiplicity of 1, degree of 4, and rises

zloy xaker [14]

Answer:

x^4+8x^3+18x-27=0

Step-by-step explanation:

In a equation of the form

$(x-a)^n(x-b)^m=0$

you have roots in x=a and x=b, and multiplicity of n and m respectively.

Hence, the equation is

$(x-(-2))^3(x-1)=0\\(x+2)^3(x-1)=0\\$

by expanding the factors you have

$(x^3+3x^2(3)+3x(3)^2+(3)^3)(x-1)=0\\(x^3+9x^2+27x+27)(x-1)=0\\x^4+9x^3+27x^2+27x-x^3-9x^2-27x-27=0\\x^4+8x^3+18x^2-27=0$

HOPE THIS HELPS!!

Lim x—> -2 <br> sqrt(3x+10) -2/ x+2

snow_lady [41]

$\displaystyle\lim_{x\to-2}\frac{\sqrt{3x+10}-2}{x+2}$

Rationalize the numerator:

$\dfrac{\sqrt{3x+10}-2}{x+2}\cdot\dfrac{\sqrt{3x+10}+2}{\sqrt{3x+10}+2}=\dfrac{(3x+10)-4}{(x+2)(\sqrt{3x+10}+2)}=\dfrac3{\sqrt{3x+10}+2}$

where the $x+2$ factors in the numerator and denominator cancel. Then the limit is

$\displaystyle\lim_{x\to-2}\frac{\sqrt{3x+10}-2}{x+2}=\lim_{x\to-2}\frac3{\sqrt{3x+10}+2}=\frac3{\sqrt4+2}=\boxed{\frac34}$

If 2 1/2 pounds of bananas cost 1.89 what is the cost per pound?

pochemuha

So we can turn the fraction into a decimal to make it easier

2.5 lbs (pounds)

since the bananas cost $1.89, we need to divide it with 2.5

1.89/2.5

=0.756

the answer would be $0.76

The equation y = 0.75x + 10 describes the cost, y, of placing an ad with x words in the classified section of a newspaper. How m

poizon [28]

y = cost = $25

25 = 0.75 +10

subtract 10 from each side

15=0.75x

x = 15/0.75 = 20

there were 20 words in the ad
