Answer:
x = 4
Step-by-step explanation:
Distribute parenthesis on both sides of the equation
4x + 4 = 6x - 4 ( subtract 6x from both sides )
- 2x + 4 = - 4 ( subtract 4 from both sides )
- 2x = - 8 ( divide both sides by - 2 )
x = 4
Hello!
The equation for find the h when given volume and radius is
h is height
v is volume
r is radius
Put in the values you know
Since there is pi on the top and bottom we can get rid of it
multiply the 3 by the top number
the answer is 8m
Hope this helps!
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.
