For question 4, it would be a^2+b^2=c^2. So you would set up the equation as a^2+14^2=18^2. the third side would equal approximately 23cm.

1.Area of rectangle=150 sq.feet
New length=15/5=3 feet
New breadth=10/5=2 feet
New area=15 sq.feet
∴Area is decreased by 135 sq.feet.

2. TSA of a sphere =4πr²=100π
⇒4r²=100
⇒r²=25
⇒r=5 cm
Volume=4/3πr³
=4/3×3.14×125
=392.5 cm³

Determine the multiplicity of the roots of the function k(x) = x(x + 2)3(x + 4)2(x − 5)4. 0 has multiplicity −2 has multiplicity

wolverine [178]

Answer:

0 has multiplicity 1

-2 has multiplicity 3

-4 has multiplicity 2

5 has multiplicity 4

Step-by-step explanation:

The multiplicity of the root of a polynomial function, refers to the number of time the root repeats itself.

The given function is

$k(x)=x(x+2)^3(x+4)^2(x-5)^4$

To find the roots of this function, we equate the function to zero.

$x(x+2)^3(x+4)^2(x-5)^4=0$

We now use the zero product principle, to obtain;

$x=0$ , with multiplicity 1

$(x+2)^3=0$

$\Rightarrow x=-2$ , with multiplicity 3

$(x+4)^2=0$

$\Rightarrow x=-4$ , with multiplicity 2

$(x-5)^4=0$

$\Rightarrow x=5$ , with multiplicity 5.
