On the graph of f(x)=cos x and the interval [0,2π), for what value of x does f(x) achieve a minimum?

Mariulka [41]

Answer:

$cos(\pi)=-1$

Step-by-step explanation:

$f(x)=cos (x)$

State that the values where cos x is minimum:

$x=\pi +2\pi n, n\in \mathbb{Z}$

$cos(0)=1\\$

$cos\left(\frac{\pi}{4} \right)=\frac{\sqrt{2} }{2}$

$cos\left(\frac{\pi}{2} \right)=0$

$cos(\pi)=-1$

$cos\left(\frac{3\pi}{2} \right)=0$

In the 2009 to 2010 school year in country a there were 127,004 in students from country B. This number is 24% more than the num

adoni [48]

If x represents the number of students from country C.

then 122% of x = 116,000

122/100 * x = 116000

Transposing the formula for x;

therefore x = 116000 * 100/122 = 95,082 students

A − 7 = 3 (b+2) pls answer soon

Alexeev081 [22]

I believe the answer is....

For solving for a

a-7= 3(b+2) ———> distribute 3(b+2)
a-7= 3b+6 ———-> add 7 on both sides

a-7= 3b+6
a+7= 3b +7 ———-> the 7’s cancel out so you’re left with....

a = 3b + 13 (That’s your answer)

Hope that helped :3
