Answer:

540 people

Step-by-step explanation:

First, to get the minutes to hours you have to multiply 15 by 4 because there are 4 sets of 15 minutes in an hour. You get 180 people an hour.

Now you have to get to three hours so you have to multiply 180 by 3 so you get 540 people for 3 hours because when you multiply an hour by 3 you get three hours.

That's why the answer is 540 people in 3 hours.

What is the equation of the graph below?

IgorC [24]

ANSWER

$f(x) = (x + 3)^{2} - 1$

EXPLANATION

The vertex of the graph is at

$(-3,-1)$

The equation of the graph in vertex form is given by the formula,

$f(x) = a{(x - h)}^{2} + k$

The above graph has a minimum point, hence
$a > \: 0$

When we put these values into the equation we obtain,

$f(x) = a(x - - 3)^{2} + - 1$

This implies that,

$f(x) = a(x + 3)^{2} - 1$

The point (-2,0) lies on the line.

$a( - 2 + 3)^{2} - 1 = 0$

$a = 1$

$f(x) = (x + 3)^{2} - 1$

The correct answer is D.

Please help me Find X

The labeled angle is what's called an inscribed angle. There's a theorem (fittingly called the inscribed angle theorem) that says the measure of this angle is half the measure of the circular arc that it subtends.

In this case, the angle is subtended by an arc measuring 180°. So

(4x + 6)° = 1/2 • 180°

4x + 6 = 90

4x = 84

x = 21
