Acone is sliced such that the cross section is perpendicular to its base and the cross section intersects its vertex. what is the shape of the cross section?

trapezoid
triangle
circle
rectangle

Circle, A cone is made of circles that get smaller

triangle

Step-by-step explanation:

when i used my cup i know it dosent have a point but it is something to work with when i tiped it up side down and imagined a point i imagined it being cut up to down that got me a triangle when you dont you will get a trapezoid because it has no point but a cone will have one not a cup when you add a point to the trapezoid it will become a triangle either way you will end up with a triangle if you cut it the right way so it dosent matter how you will during the process.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
