Answer: $-\frac{\sqrt{3} }{3}$

Step-by-step explanation:

Tan is $\frac{sin}{cos} \\\\$

sin is the y coordinate

Cos is the x-coordinate

$\ \frac{11\pi }{6} = (\frac{\sqrt{3} }{2} ,-\frac{1}{2})\\$

$tan=\frac{\frac{1}{2} }{\frac{\sqrt{3} }{2} }$

$-\frac{1}{2} *\frac{2}{\sqrt{3} } =- \frac{1}{\sqrt{3} } *\frac{\sqrt{3} }{\sqrt{3} } =-\frac{\sqrt{3} }{3}$

BAYES FORMULA

djverab [1.8K]

Answer:

republicans

Step-by-step explanation:

Given, there are 60% democrats and republicans 40%

60% of the democrats voted for democrats and 95% of the republican voted for their candidate

therefore

% of votes that went for Democrats =0.6*0.6=0.36 = 36%

% of votes that went for Republics=0.4*0.95=0.38 = 38%

Since the republicans have more % of votes thus Republic's mayor runs city hall.

If f(x)=×^2+7x-5 and you divide by x-2, What is the quotient and remainder?

katrin [286]

Answer:

The quotient is : x+9

The remainder is : 13

Step-by-step explanation:

The question requires you to perform the long division method;

This will be;

$x-2\sqrt{x^2+7x-5}$

start with the x term in x-2 and the first term in the function, x², to get x then multiply the x with x-2 to get x²-2x and perform the operation below;

x-2√x²+7x-5 -----------to first get x and then multiply x*[x-2]⇒x²-2x

- x²-2x+0 ------------perform subtraction of like terms

---------------------

9x-5 ----now divide this answer by x-2 ,starting with x and 9x

----------------------This will give , 9 then multiply 9 by x-2 to get 9x-18 and perform the subtraction operation as;

9x-5

- 9x-18

------------------------

So the answer will be; x+9 remainder 13

Hi, can someone help with these two questions ASAP! (Ignore the multiple choice I circled, not sure if it’s correct)

Sindrei [870]

Answer:

1) D. $y = -\frac{3}{2}\cdot x^{12} -7\cdot x^{5}+\frac{2}{3}\cdot x -10$

2) E. The coefficient of $x$ is -16.

Step-by-step explanation:

1) A polynomial is an algebraic expression of the form $p(x) = \Sigma \limits_{i = 0}^{n} c_{i}\cdot x^{i}$ , where $n$ is the grade of the polynomial. In this case, the only equation that satisfies this definition is:

$y = -\frac{3}{2}\cdot x^{12} -7\cdot x^{5}+\frac{2}{3}\cdot x -10$

Correct answer: D

2) Let $p(x) = (2\cdot x + 1) \cdot (5\cdot x^{3}-8\cdot x +4)$ , we proceed to expand the expression by algebraic means:

$p(x) = (2\cdot x + 1)\cdot (5\cdot x^{3}) -(2\cdot x +1)\cdot (8\cdot x) + 4\cdot (2\cdot x + 1)$

$p(x) = 10\cdot x^{4}+5\cdot x^{3}-16\cdot x^{2}+4$

We see that coefficients for $x^{2}$ and $x$ are -16 and 0, respectively. Hence, the incorrect answer is E.
