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

Step-by-step explanation:

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

sin is the y coordinate

Cos is the x-coordinate

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

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

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

Elina [12.6K]

option D is the correct option

y= 10- 2x

Now, if we take the first value of x i.e 1

then, y= 10-2(1)

= 10-2 = 8 ---------> this value matches with the given value of y

take,x =2

y=10-2(2) = 10-4 = 6--------->this value matches with the given value of y

taking, x = 3

y= 10-2(3) = 10- 6=4-------->this value matches with the given value of y

You deposit $200 in an account earning 3.5% simple interest how long will it take for the balance of the account to be $221

Rus_ich [418]

It takes 3 years for the balance of account to be $ 221

Solution:

From given information,

Principal = $ 200

Rate of interest = 3.5 %

Amount after "n" years = $ 221

To find: number of years

In simple Interest,

Simple interest = amount earned - principal

Simple interest = 221 - 200 = 21

Thus simple interest earned is $ 21

The formula for simple interest is given as:

$simple\ interest = \frac{ p \times n \times r}{100}$

Where,

p is the principal

n is the number of years

r is the rate of interest per annum

Substituting the given values in formula,

$21 = \frac{200 \times n \times 3.5}{100}\\\\21 = 2n \times 3.5\\\\n = \frac{21}{7}\\\\n = 3$

Thus it takes 3 years for the balance of account to be $ 221
