Answer:

The correct answer is the first choice.

Step-by-step explanation:

Let's solve your inequality step-by-step.

−2x>6

Step 1: Divide both sides by -2.

$\frac{-2x}{-2}$ > $\frac{6}{-2}$

x < −3 <== this equation matches the graph

The correct answer is a because when you divided by the negative 2 it flips the sign and then it is open because it doesn’t have a line underneath

Evaluate the expression for the given value of the variable.<br><br><br>n=500<br>∛n/4+n/10=?

schepotkina [342]

Answer:

Step-by-step explanation:

To solve the expression, $\sqrt[3]{\frac{n}{4}} + \frac{n}{10}$ substitute n = 500 and simplify according to order of operations.

$\sqrt[3]{\frac{500}{4} } + \frac{500}{10}\\\\\sqrt[3]{125}+50\\ 5+50\\\\55$

Find the coordinates of the point (a, b).

Leviafan [203]

Answer:

a = $\frac{1}{\sqrt{2} }$ and b = $\frac{\sqrt{2} }{2}$

Step-by-step explanation:

As we know, the radius of the unit circle is 1 unit (it is the hypotenuse in the right triangle, the blue line)

We use trigonometric formulas to find out a and b

Sin(45) = opposite side / hypotenuse

<=> Sin(45) = b / 1

<=> b= Sin(45)*1 = $\frac{\sqrt{2} }{2}$

Cos(45) = adjacent side / hypotenuse

<=> Cos(45) = a / 1

<=> a = Cos(45)*1 = $\frac{1}{\sqrt{2} }$

So: a = $\frac{1}{\sqrt{2} }$ and b = $\frac{\sqrt{2} }{2}$
