<h2>For the number 1..</h2>

<h2>angle at center = 2×angle at circumference</h2><h2>the angle at center (o) is equal to 141</h2>

therefore:

<h2>141 = 2x</h2><h2>divide both sides by 2</h2><h2>x = 70.5</h2>

option (A).

( the number 2 and 3 questions aren't correct )

4. Miguel is helping his mom paint his home. He finished 2 rooms in ⅓ of an hour. How many rooms can he paint in 1 hour?

lilavasa [31]

Answer: 6

Step-by-step explanation:

Let's use a rule of three here.

2 rooms in 1/3 h

x rooms in 1 h

$\frac{2}{x}=\frac{\frac{1}{3} }{1}$

Solve for x;

$x=\frac{2*1}{\frac{1}{3} }$

Remember that when you divide by a fraction, you invert the fraction and multiply by the numerator.

1/3 inverted is 3/1 or 3

$x=(2*1)*3$

$x=(2)*3\\x=6$

2sec^2x - secx - 1 = 0

Ivenika [448]

What are you trying to do here?
Solve the graph, or make it appear as something else?

First, we're going to take one sec (x) out so that we get:
sec (x) (2sec (x) -1 -1) = 0

sec (x) (2sec (x) -2) = 0

Then we're going to separate the two to find the zeros of each because anything time 0 is zero.

sec(x) = 0

2sec (x) - 2 = 0

Now, let's simplify the second one as the first one is already.

Add 2 to both sides:

2sec (x) = 2

Divide by 3 on both sides:

sec (x) = 1

I forgot my unit circle, so you'd have to do that by yourself. Hopefully, I helped a bit though!
