The smallest angle of rotational symmetry for a regular polygon is 30°. how many sides does the regular polygon have? 9 12 20 30
The regular polygon must have 12 sides so the smallest angle of rotational symmetry is 30°
How many sides the polygon have?We know that the smallest angle of rotational symmetry is 30°, then the exterior angles must measure that.
Remember that the sum of the exterior angles of a regular polygon must be equal to 360°, then we have:
360° = n*30°
Where n is the number of sides
Solving for n we get:
n = 360°/30° = 12
We conclude that the regular polygon has 12 sides.

Many large cities have considered or passed proposals that ban the use of plastic grocery bags in stores. A concerned student would like to measure if residents of her hometown would consider a similar ban on plastic bags. Standing in a busy shopping area, the student approaches adults and asks, "Items made of plastics are a dangerous, growing source of pollution to our world’s oceans and threaten many animal species. Given this, would you support a ban on plastic shopping bags in our city stores?” How might the results of this survey be biased in estimating the proportion of all town residents who would support a ban on plastic bags?
The student may overestimate support for a plastic bag ban because only adults in the shopping area were chosen to participate.
The student may overestimate support for a plastic bag ban because the wording of the question may influence adults to support a ban.
The student may underestimate support for a plastic bag ban because the wording of the question may influence adults to not support a ban.

С.

Answer:
Answer: 3, 3 of them are translated
Answer:
B. 3 triangles are congruent to ABC
Step-by-step explanation:
2 triangles are congruent if all corresponding side lengths are equal, or using SAS (Side-Angle-Side theorem) to confirm 2 corresponding sides & the included angle is equal those of another triangle.From the picture, triangle ABC is not a right triangle. The length of AB is graphed with a length of 4. From point C to segment AB is a height of 3. The triangle in quadrant I (top right) has both of these dimensions.
Similarly, the triangle on the x-axis (positive side) below it (between Q1 and Q4) is also congruent to ABC.
The triangle fully in quadrant III (bottom left) is congruent to ABC with a height of 3 and base length of 4.
The triangle in the bottom right corner (Q4) has a height of 4, therefore it is not congruent to ABC which has a height of 3.
The triangle on the x-axis (negative left side) is also not congruent to ABC. It may have a height of 3 and base length 4, but the angles are different which means the other side lengths don't correspond to ABC.
[+ I'm not sure if your teacher would consider this a real answer but I figured I'd mention that in proofs tri.ABC is also congruent to tri.ABC.]

HELPPPPP QUICKLYYY !!! The picture shows a cylinder of height x which has been inscribed in a sphere of radius r. Find the volume of a cylinder in terms of x.
See attached. We can draw a right triangles contained within both shapes.
The triangle has height x (same as the cylinder), base 2r (same as the diameter of the cylinder), and hypotenuse 6 (same as the diameter of the sphere).
Since it's a right triangle, the Pythagorean theorem holds and we have
x² + (2r)² = 6²
which we solve for r to get
x² + 4r² = 36
4r² = 36 - x²
r² = 9 - x²/4
r = √(9 - x²/4)
Then the volume of the cylinder, whose height is x and whose base has radius r, is
π r² x = π (9 - x²/4) x = (36x - x³) π/4

Since we have given : [tex]z_1[/tex]==4-4[tex]\sqrt{3i}[/tex] and [tex]z_2[/tex]= -16i
The difference of z1 - z2 would be:

If an item has a retail price = $475 and a discount of $45, what percentage discount is offered?
Answer:
A 9.47% discount was given
Step-by-step explanation:
The question is asking us to find how much percent of 475 is 45. Therefore we do the following:
[tex] \frac{45}{475} \times \frac{100}{1} = \frac{4500}{475} [/tex]
after dividing we get 9.473 which is approximately 9.47%
To check if what we got is correct we do the opposite and instead find 9.47% of 475.
[tex] \frac{475}{1} \times \frac{9.47}{100} = \frac{4498.25}{100} [/tex]
After dividing we find that is equal to 44.98 which is approximately 45.

What is the height of a cone if the radius is 3 and the volume is 40π
Does anybody know this? I followed the example and did the formula and it told me it was 11.99 but it was wrong. Find the length of the radius if the area of the sector is 361.6 and the central angle is 288 use 3.15 round your answer to the neatest whole number
Hi Student!
The first step that we need to take to solving this problem (and almost any problem), is to concentrate the important information for the problem that is provided. Looking at the problem we can see that we are trying to determine what the length of the radius is. In order to solve this problem we are provided with the area of a sector of 361.6 meters squared and a central angle of 288 degrees.
Now that we have the important information taken care of, we can move onto the part of actually solving the problem. We must first convert our degrees to radians because the equation that we will be using can only use radians for the angle and not degrees. We can simply convert our angle to radians by multiplying it by π/180.
[tex]288\ degrees\ *\ \frac{\pi }{180\ degrees}[/tex]
[tex]288\ degrees\ *\ \frac{3.14}{180\ degrees}[/tex]
[tex]\frac{288\ degrees\ *\ 3.14}{180\ degrees}[/tex]
[tex]5.024\ radians[/tex]
After completing this step, we have converted our degrees to radians and now we can move onto the step where we plug in our information into an equation and solve for our unknown.
[tex]Sector\ Area = radius^2\ *\ \frac{angle}{2}[/tex]
[tex]361.6\ m^2 = radius^2\ *\ \frac{5.024}{2}[/tex]
[tex]361.6\ m^2 = radius^2\ *\ 2.512[/tex]
[tex]\frac{361.6\ m^2}{2.512} = \frac{radius^2\ *\ 2.512}{2.512}[/tex]
[tex]143.949\ m^2 = radius^2[/tex]
[tex]\sqrt{143.949\ m^2} = \sqrt{radius^2}[/tex]
[tex]12\ m = radius[/tex]
Therefore, after solving our equation for our unknown, we can see that our radius is really close to 12 meters (so we can just round up as the problem stated).

1. (a) Solve the differential equation (x + 1)Dy/dx= xy, = given that y = 2 when x = 0. (b) Find the area between the two curves y = x2 and y = 2x – x2.
(a) The differential equation is separable, so we separate the variables and integrate:
[tex](x+1)\dfrac{dy}{dx} = xy \implies \dfrac{dy}y = \dfrac x{x+1} \, dx = \left(1-\dfrac1{x+1}\right) \, dx[/tex]
[tex]\displaystyle \frac{dy}y = \int \left(1-\frac1{x+1}\right) \, dx[/tex]
[tex]\ln|y| = x - \ln|x+1| + C[/tex]
When x = 0, we have y = 2, so we solve for the constant C :
[tex]\ln|2| = 0 - \ln|0 + 1| + C \implies C = \ln(2)[/tex]
Then the particular solution to the DE is
[tex]\ln|y| = x - \ln|x+1| + \ln(2)[/tex]
We can go on to solve explicitly for y in terms of x :
[tex]e^{\ln|y|} = e^{x - \ln|x+1| + \ln(2)} \implies \boxed{y = \dfrac{2e^x}{x+1}}[/tex]
(b) The curves y = x² and y = 2x - x² intersect for
[tex]x^2 = 2x - x^2 \implies 2x^2 - 2x = 2x (x - 1) = 0 \implies x = 0 \text{ or } x = 1[/tex]
and the bounded region is the set
[tex]\left\{(x,y) ~:~ 0 \le x \le 1 \text{ and } x^2 \le y \le 2x - x^2\right\}[/tex]
The area of this region is
[tex]\displaystyle \int_0^1 ((2x-x^2)-x^2) \, dx = 2 \int_0^1 (x-x^2) \, dx = 2 \left(\frac{x^2}2 - \frac{x^3}3\right)\bigg|_0^1 = 2\left(\frac12 - \frac13\right) = \boxed{\frac13}[/tex]
