Answer:

Step-by-step explanation:

x = 27, y = - 4, z = 64

Expression:

2∛x - 5√z + y² =
2∛27 - 5√64 + (-4)² =
2(3) - 5(8) + 16 =
6 - 40 + 16 =
-18

Answer:

c=10

Step-by-step explanation:

pythagreom theroem

c (hypotenuse) = $\sqrt{a^{2} +b^{2} }$

plug in values for a and b

c= $\sqrt{6^{2} +8^{2} }$

c= $\sqrt{36+64\\}$

c= $\sqrt{100\\}$

c=10

the rational roots of a polynomial function f(x) can be written in the form p/q where p is a factor of the leading corfficient o

Lorico [155]

False.

The Rational Root theorem states that P is a factor of the constant term and q is a factor of the leading coefficient.

What much expression represents a rational number?

Pie

Answer:

$\displaystyle \frac{2}{7}+\sqrt{121}$

Step-by-step explanation:

Rational Numbers

A rational number is any number that can be expressed as a fraction

$\displaystyle \frac{a}{b}, \ b\neq 0$

for a and b any integer and b different from 0.

As a consequence, any number that cannot be expressed as a fraction or rational number is defined as an Irrational number.

Let's analyze each one of the given options

$\displaystyle \frac{5}{9}+\sqrt{18}$

The first part of the number is indeed a rational number, but the second part is a square root whose result cannot be expressed as a rational, thus the number is not rational

$\pi + \sqrt{16}$

The second part is an exact square root (resulting 4) but the first part is a known irrational number called pi. It's not possible to express pi as a fraction, thus the number is irrational

$\displaystyle \frac{2}{7}+\sqrt{121}$

The square root of 121 is 11. It makes the whole number a sum of a rational number plus an integer, thus the given number is rational

$\displaystyle \frac{3}{10}+\sqrt{11}$

As with the first number, the square root is not exact. The sum of a rational number plus an irrational number gives an irrational number.

Correct option:

$\boxed{\displaystyle \frac{2}{7}+\sqrt{121}}$
