Rational numbers end
irrational numbers do not
pi is an irrational number
√2 is an irrational number
so
√50=√2 times √25=√2 times 5
irrational times rational =irrational
√2=irrational

Question 20 please make (x) the subject of the formula

Masja [62]

Answer:

The answer is

$\frac{ {x}^{2} - n}{m} = { (\frac{ {a}^{2} }{b}) }^{a} \\ {x}^{2} - n = m{( \frac{ {a}^{2} }{b} })^{a} \\ {x}^{2} = m {( \frac{ {a}^{2} }{b} )}^{a} + n \\ x = \sqrt{m {( \frac{ {a}^{2} }{b}) }^{4} - n}$

Use the Remainder Theorem to evaluate f(10) for:<br> f(x) = 2x^3 – 14x^2 - 56x - 40

MAXImum [283]

Step-by-step explanation:

Since we are told that 10 is a zero,

(x−10) must be a factor:

F(x)=2x3−14x2−56x−40

F(x)=(x−10) (2x2+6x+4)

F(x)=2(x−10)(x2+3x+2)

F(x)=2(x−10)(x+2)(x+1)

So the other two zeros are

x = -2 and x= −1
