nikdorinn [45]

Answer:

regular tessellation

Step-by-step explanation:

A regular tessellation is a repeating pattern of congruent regular polygons on a plane with no gaps or overlaps.

Since a regular tessellation is with no gaps and overlaps, the only regular polygons that will tessellate are equilateral triangles, squares and regular hexagons. Therefore, there are only three types regular tessellations (ones made from squares, equilateral triangles and hexagons),

To test an individual's use of a certain mineral, a researcher injects small amount of a radioactive form of that mineral into t
Ostrovityanka [42]

Answer:

dC/dt = 2 mg*cm³/s

Step-by-step explanation:

Given

C(t)= (1/2)*(4t+ 4)- (1/2)

we apply dC/dt as follows

dC/dt = d((1/2)*(4t+ 4)- (1/2))/dt = (1/2)*(4) = 2

⇒   dC/dt = 2 mg*cm³/s

30 POINTS Which is an x-intercept of the graph of the function y=cot(3x)?
Allisa [31]

Answer:

x=\frac{\pi}{6}

Step-by-step explanation:

Choices aren't given, so i will solve this equation and find the first positive x-intercept angle.

First, x-intercept means the x-cutting point of the graph. This occurs when y = 0. So we will solve the equation for x. Shown below:

y=Cot(3x)\\Cot(3x)=0\\ArcCot(Cot(3x))=ArcCot(0)\\3x=ArcCot(0)

Inverse Cotangent (ArcCot) of 0 is at  \frac{\pi}{2}, so we can now solve for x:

3x=ArcCot(0)\\3x=\frac{\pi}{2}\\x=\frac{\pi}{6}

So, the x-intercept is at x = pi/6
