You're given an angle, the side adjacent to the angle, and are looking for the hypotenuse.

Use cosine = adjacent / hypotenuse.

cos(60) = 2√(3) / x

Rearrange the equation to solve for x (multiply both sides by x, then divide both sides by cos(60)).

x = (2√(3)) / (cos(60))

x equates to about 6.928

Solve 3.5x-2.8=-3.8x-7.2 graphically
pshichka [43]

x= -0.6

The graph is attached in the figure below.

Step-by-step explanation:

Solve 3.5x-2.8=-3.8x-7.2

Simplifying:

3.5x-2.8=-3.8x-7.2

Combining like terms:

3.5x+3.8x=-7.2+2.8\\7.3x=-4.4\\x=\frac{-4.4}{7.3}\\x=-0.6

x= -0.6

The graph is attached in the figure below.

The figure shows a plane slicing through a cone. The plane is neither parallel nor perpendicular to the base of the cone, and th
aalyn [17]
<h3>Answer:   Ellipse</h3>

==================================================

Explanation:

Imagine that this plane was a saw blade, or a laser, that cut the cone. We would have two pieces and each piece would have a shape of an ellipse on them. The cutting plane would also have the same ellipse shape.

Or you think of the cutting plane as a flat piece of cloth. If we cut everything around the cone, then we would have an ellipse shaped hole as a result.

The reason why we get an ellipse and not a circle is because the plane is angled like that. It needs to be perfectly parallel to the circular base in order to get a circular cross section.

Solve 4^x+2 = 12 for x using the change of base formula log base b of y equals log y over log b.
valentinak56 [21]

The value of x is 1.66

Step-by-step explanation:

Let use revise the rules of exponential and logarithmic equations

1. If y = b^{x}, then log_{b}(y)=x

2. log_{b}(y) = \frac{log(y)}{log(b)}

Use the rules above to solve the problem

∵ 4^{x}+2=12

- Subtract 2 from both sides

∴ 4^{x}=10

change the exponential equation to logarithmic equation

∴ log_{4}(10)=x

∵ log_{4}(10) = \frac{log(10)}{log(4)}

∴ x = \frac{log(10)}{log(4)}

∴ x = 1.66

The value of x is 1.66
