The answer is -2 because, once you distribute the 3, 6t cancels out and leaves you with 3-5 which equals -2

Name the conic section formed when a plane cuts a right circular cone parallel to its base.

gregori [183]

Answer:

option 1.

circle

Step-by-step explanation:

A section is formed when a solid shape is sliced into two. A conic section is therefore formed when a cone, is sliced into two.

What determines the shape of the section now, is the angle at which the cone was sliced.

Normally, the base of a cone is a circle. If we slice a cone using a straight line, which runs parallel to its base, we will still get another perfect cone, but with a smaller height.

If we look at the flat portion of the cone after it has been sliced, we will see that the cross-section is a circle.

Find the measure of the line segment GE. Assume that lines which appear tangent are tangent.

ch4aika [34]

Answer:

The measure of the line segment GE is $18\ units$

Step-by-step explanation:

we know that

<u>The Intersecting Secant-Tangent Theorem</u> , states that the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment

In this problem

$GE*GF=GH^{2}$

substitute the values

$(8+x)(8)=12^{2}$

solve for x

$8x+64=144$

$8x=144-64$

$8x=80$

$x=10$

Find the measure of the line segment GE

$GE=8+10=18\ units$

Can someone explain aswell

Svet_ta [14]

Answer:

24 ft²

Step-by-step explanation:

find the length of the base of each triangle through a² + b² = c², c being hypotenuse.

after finding the length of each individual base, use A= 1/2bh (multiply base and height and then divide by 2) to calculate area of each triangle. then add and round. hope this helps
