Answer:

The factors are;

(x + 4) , (x + 1) and (2x-1)

Step-by-step explanation:

Given the zeros, we want to get the factors

To get the zeros, we simply equate the factors to zero and solve for x

so for x = 1/2

we can have x - 1/2 = 0

multiply through by 2

= 2x - 1

for x = -4

x + 4

for x = -1

x + 1

So the factors are;

(x + 1) , (x + 4) and (2x-1)

Find the volume of the cone

irina1246 [14]

Answer:

The volume of the cone is 12936 cubic mm.

Step-by-step explanation:

Given

Circumference of base = 132 mm

Height of the cone = 28 mm

Solution

Formula of circumference = $2\pi r$ = 132 mm

$\therefore\ r= \frac{132}{2 \pi } = 21 mm$

Now volume of cone = $\frac{1}{3} \times\pi \times r^{2} \times h$

on substituting the value of r and h we get ;

$\frac{1}{3}\times\frac{22}{7} \times21\times21\times28= 12936\ mm$

thus volume of cone is 12936 cubic mm.

F(x)=x^2-x^3 find the value of f(-2)

gulaghasi [49]

The Correct answer is 3

Explanation:

Using the defined function, f(a) will produce the same result when substituted for x:

F(x)=x^2-x^3

Setting this equal to 4, you can solve for a:

a2 – 5 = 4

a2 = 9

a = –3 or 3

Dennis_Churaev [7]

Step-by-step explanation:

5^5•5 = 5^3

y^2/y= y^1 =y

a^2•a^3•a= a^6

b^5/b^7= b^-2

y^5/y^4=y

m^3•m^5•m^2=m^10
