Let's go though the choices.
Major axis will get shorter. TRUE, CHECK ME
As the plane moves closer to the vertex the ellipse stays the same shape but shrinks.
Ellipse will become a circle. FALSE
As long as the plane is tilted, the ellipse can't be a circle.
Ellipse will degenerate to a point. TRUE, CHECK ME
Eventually the plane gets to the vertex, at which point (ha!) we have a single point.
Nappes? Is that a word? FALSE
The plane needs a steeper angle, steeper than the generators, before it can pass through both halves.
The generators are the lines through the vertex that form the cone. The plane isn't steep enough to hold any of them. FALSE
Answer:
The diameter would be 16
Step-by-step explanation:
The area of a circle is a=
×π. Now just plug in the values you have which is you area. 201=×π now divide by pi on both sides you that you get about 64=. Now find the square root on both sides which will then give you 8 as your radius. To find diameter from radius you have to multiply by 2. 8*2=16
Answer:
7680 rabbits
Step-by-step explanation:
Let y represent the number of rabbits after x days and let x represent the number of days. This is an exponential growth equation in the form:
Since there is an initial value of 26 rabbits on the farm and the rabbits double every 30 days, hence the equation becomes:
There are 20 pieces in the bag all together. Four are chocolate.
The probability of picking a chocolate with his eyes closed is 4/20.
In simplest form, that's 1/5 or 20% .
