There is no solution to the equation cscx=0.<br> True or False

Svetradugi [14.3K]

Answer:

True

Step-by-step explanation:

First, we need to recognize that

$csc(x)=\frac{1}{sin(x)}$

Now, we can try to solve

$\frac{1}{sin(x)} =0$

Multiply each side by $sin(x)$

$1=0*sin(x)\\\\1=0$

As we end up with an answer that cannot be true, we know that there is no solution.

Another method to solve this would be graphing the function $y=csc(x)$

When graphed, it can be seen that there is an asymptote at x=0 meaning that there is no value for x=0.

How Do I solve this I am quite confused

Kazeer [188]

Answer:

$11,714

Step-by-step explanation:

C(x) = 0.7x² - 462x + 87,944

this is a quadratic equation that opens up

the vertex will be the minimum

From the quadratic formula the x coordinate of the vertex is

x = -b/2a

x = 462/(2 * 0.7)

x = 330

Plug in

c(330) = 0.7(330²) - 462(330) + 87,944

c(330) = 11,714

$11,714
