Answer:
y = 4x + 2
Step-by-step explanation:
You would use point slope to solve this. y-y = m(x-x) m represents the slope. With your numbers it would look like this ------> y-6 = 4(x-1)-----> distribute the 4 -----> y-6 = 4x - 4 ------> add six on both sides ------> they cancel out on the left ------> y = 4x + 2. Hope this helped!!!!
Cosine is a trigonometric function. The value of cos(x+π), when the value of cos(x)=-(√3)/2 is √3/2. The correct option is A.
<h3>What is a cosine?</h3>
Cosine is the trigonometric function equal to the ratio of the side next to an acute angle to the hypotenuse in a right-angled triangle.
Given the value of cos(x)=-(√3)/2, therefore, the value of x can be written as,
cos(x) = -(√3)/2
(x) = cos⁻¹ [-(√3)/2]
x = 5π/6 = 150°
Now, the value of cos(x+π) will be,
cos(x+π)
= cos[(5π/6)+π]
= cos(11π/6)
= √3 / 2
Hence, the value of cos(x+π), when the value of cos(x)=-(√3)/2 is √3/2.

Answer:
Yes
Step-by-step explanation:
To be able to make a right triangle, it needs to follow the Pythagorean theorem
Thus, 16^2+30^2=34^2 needs to be true
256+900=1156
and sqrt1156=34
so yes
The radius of a circle is half way in the center.
The diameter of a circle is all the way in the center.
