SpyIntel [72]
y=ax^2+bx+c\\\\vertex:(x_v;\ y_v)\\\\x_v=\frac{-b}{2a}\ and\ y_v=f(x_v)


y=x^2-2x-1\\\\a=1;\ b=-2;\ c=-1\\\\x_v=\frac{-(-2)}{2\cdot1}=\frac{2}{2}=1\\\\y_v=1^2-2\cdot1-1=1-2-1=-2\\\\Answer:(1;-2)

SVETLANKA909090 [29]

Answer:

<h3>1/8</h3>

Step-by-step explanation:

Given the expression

\frac{(2^3)(2)^4}{2^{10}} \\

Using the following laws of indices;

\frac{a^m}{a^n}  = a^{m-n}\\a^m \times a^n = a^{m+n}

The expression becomes;

Step 1: Multiplication rule

=\frac{(2^3)(2)^4}{2^{10}} \\= \frac{2^{3+4}}{2^{10}}\\= \frac{2^7}{2^{10}}

Using the division rule of exponent (Quotient of powers);

= \frac{2^7}{2^{10}} \\= 2^{7-10}\\= 2^{-3}\\also \ a^{-m} = \frac{1}{a^m}\\ 2^{-3}=  \frac{1}{2^3}\\\frac{1}{2^3} = \frac{1}{8}

Hence the result of the expression is 1/8
