According to the Fundamental Theorem of Algebra, the number of roots of a polynomial is equal to the degree of the polynomial. The degree of the polynomial is the highest exponent of a term in the polynomial.
Looking at the function, the term with the highest exponent is 8x7. The exponent is 7; therefore, the function has 7 roots.

According to the Fundamental Theorem of Algebra, the roots exist for the polynomial function f\left( x \right) = 8{x^7} - {x^5} + {x^3} + 6 x is \boxed7.

Further explanation:

The Fundamental Theorem of Algebra states that the polynomial has n roots if the degree of the polynomial is n.

f\left( x \right) = a{x^n} + b{x^{n - 1}} +\ldots  + cx + d

The polynomial function has n roots or zeroes.

Degree is highest power of the polynomial function.

Given:

The polynomial function is f\left( x \right) = 8{x^7} - {x^5} + {x^3} + 6.

Explanation:

The polynomial function f\left( x \right) = 8{x^7} - {x^5} + {x^3} + 6 has seven zeroes as the degree of the polynomial is 7.

According to the Fundamental Theorem of Algebra, the roots exist for the polynomial function f\left( x \right) = 8{x^7} - {x^5} + {x^3} + 6 is \boxed7.

A rectangular box has a square base with an edge length of x cm and a height of h cm. The volume of the box is given by V = x2h
Tanya [424]

Answer:

  192 cm^3/min

Step-by-step explanation:

Differentiating the volume expression, we get ...

  dV/dt = 2xh(dx/dt) +x^2(dh/dt)

We are given that ...

  x = 4 cm, dx/dt = 2 cm/min, h = 15 cm, dh/dt = -3 cm/min

Putting these values into the formula for volume rate of change, we get ...

  dV/dt = 2(4 cm)(15 cm)(2 cm/min) +(4 cm)^2(-3 cm/min)

  = 240 cm^3/min -48 cm^3/min

  dV/dt = 192 cm^3/min

What is the kinetic energy of a 50-kg child running to catch the school bus at 2 m/s
aev [14]

Answer:

100 J

Step-by-step explanation:

The formula for kinetic energy is as follows:

\boxed{KE=  \frac{1}{2} mv²}

where

KE= kinetic energy (J)

m= mass (kg)

v= velocity (m/s)

Given: m= 50 kg, v= 2 m/s

Substituting the given information into the formula:

KE

= ½(50)(2²)

= ½(50)(4)

= 100 J
