Answer:

114°

Step-by-step explanation:

By property of intersecting chords inside a circle.

$\because \angle \: 1 = \frac{1}{2} (x + y) \\ \\ \therefore \: \angle \: 1 = \frac{1}{2} (96 + 132) \\ \\ \therefore \: \angle \: 1 = \frac{1}{2} \times 228\\ \\ \huge \red { \boxed{\therefore \: \angle \: 1 = 114 \degree}}$

Solve using Quadratic Formula <br>x^2 + 3x - 3 = 0

katrin [286]

Answer:

a= 1 , b= 3 , c= –3

$x = \frac{ - b \frac{ + }{} \sqrt{ {b}^{2} - 4ac} }{2a} \\ x = \frac{ - 3 \frac{ + }{} {} \sqrt{ {3}^{2} - 4(1)( - 3)} }{2(1)} \\ = \frac{ - 3 \frac{ + }{} \sqrt{9 + 12} }{2} = \frac{ - 3 \frac{ + }{} \sqrt{21} }{2} \\ \\ x = \frac{ - 3 \frac{ + }{} \sqrt{21} }{2} \\ \\ x = 0.79 \\ x = - 3.79$

Why would you use the measurement 8 feet 4 inches instead of 7 feet 16 inches?.

lidiya [134]

8 feet 4 inches is more precise and easier to use.

It would be weird to say 7 feet 16 inches, because there's 12 inches in a foot and your already using that measurement.

Hope this is helpful:)

Find the terminal point on the unit circle determined by pi radians.

svet-max [94.6K]

Answer:

Terminal points

$(x,y) = (\frac{1}{\sqrt{2} }) , (\frac{-1}{\sqrt{2} })$

Step-by-step explanation:

According to the question, it is provided that

$\theta = \frac{7\pi}{4}$

Now

$x = 1. cos (\frac{7\pi}{4})\\\\ = cos (2\pi - \frac{\pi}{4})\\\\= cos \frac{\pi}{4} \\\\= \frac{1}{\sqrt{2} }$

$y = 1. sin (\frac{7\pi}{4})\\\\ = sin (2\pi - \frac{\pi}{4})\\\\= -sin \frac{\pi}{4} \\\\= \frac{-1}{\sqrt{2} }$

Now

$(x,y) = (\frac{1}{\sqrt{2} }) , (\frac{-1}{\sqrt{2} })$

These two represents the terminal points

We simply applied the above equations and then equate these two equations to determine the terminal points and therefore the same is to be considered

It could be figure out by using the x and y points

Therefore the two shows the terminal points

I'm given 10=log(x) and I'm supposed to find the x-intercept.

Alex_Xolod [135]

Answer:

x = 10^10

Step-by-step explanation:

You are right to question the question. As posed, it makes no sense.

The idea of an x-intercept is applicable to a relation involving two variables that can be graphed on a coordinate plane.

If you graph this equation on an x-y plane, it will be a vertical line at x = 10^10, so that would be the x-intercept.

_____

I suggest you ask for an explanation from your teacher.

_____

The graph of y=log(x) is something else entirely, as you know. The x-intercept of that graph is x=1.
