Solve <br> f(x)=4x5−8x4+8x2−4x
Goryan [66]

Given:

The function is:

f(x)=4x^5-8x^4+8x^2-4x

To find:

The roots of the given equation.

Solution:

We have,

f(x)=4x^5-8x^4+8x^2-4x

For roots, f(x)=0.

4x^5-8x^4+8x^2-4x=0

4x(x^4-2x^3+2x-1)=0

4x((x^4-1)+(-2x^3+2x))=0

4x((x^2+1)(x^2-1)-2x(x^2-1))=0

On further simplification, we get

4x(x^2+1-2x)(x^2-1)=0

4x(x-1)^2(x+1)(x-1)=0

4x(x+1)(x-1)^3=0

Using zero product property, we get

4x=0

x=0

Similarly,

x+1=0

x=-1

And,

(x-1)^3=0

x=1

Therefore, the zeroes of the given function are -1,0,1 and the factor form of the given function is f(x)=4x(x+1)(x-1)^3.

A grocer stacks oranges in a four-sided pyramid that is 7 layers high. How many oranges are in the pile?
gayaneshka [121]
Short Answer D
P(1) = 1(1+1)(2*1 + 1)/6
P(1) = 1(2)(2 +1) / 6
P(1) = 1(2)(3)/6
P(1) = 1

P(2) = 2(2+1)(2*2 + 1) / 6
P(2) = 2(3)(5) / 6
P(2) = 5 So this formula is adding as it goes along. To Find the Total all we need do is use the formula to calculate P(1) to P(7)

P(7) = 7*(7 + 1)(2*7 + 1)/6
P(7) = 7 * 8 * 15 / 6
P(7) = 7 * 4 * 5 
P(7) = 140 <<<< Answer

Which is the best estimate for 6.3×10 to the second power times 9.9×10 to the 3rd power written in scientific notation
viva [34]

Answer:

in scientific notation, the expression can be written as 6.237 x 10⁶

Step-by-step explanation:

Given;

6.3×10 to the second power times 9.9×10 to the 3rd power

Using scientific notation, it can be interpreted as;

(6.3 \times 10^2) \times (9.9 \times 10^3)

This can be simplified as;

(6.3 \times 10^2) \times (9.9 \times 10^3) = (6.3\times 9.9)\times 10^{2+3}\\\\= 62.37\times 10^5 = 6.237\times 10^6

Therefore, in scientific notation, the expression can be written as 6.237 x 10⁶
