Can you tell the number of digits that will be in the quotient for 627 ÷ 9 by only looking at the problem? explain

Need ! give step by step solutions on how to solve number one \frac{9-2\sqrt{3} }{12+\sqrt{3} } number two x+4=\sqrt{13x-20} number three (domain and range) f(x)=2\sqrt[3]{x} +1

Asequence is defined recursively using the formula f(n + 1) =f(n) - 5. which sequence could be

The table below shows the function f. determine the value of f(3) that will lead to an average rate of change of 19 over the interval [3, 5]. a. 32 b. -32 c. 25 d. -25
