Find the shape resulting from the cross section of the cylinder
1 answer:
Answer: Second option.
Step-by-step explanation:
For this exercise it is important to remember that, by definition, a "Cross section" is the two-dimensional shape obtained by the intersection of a three-dimensional body with a plane.
In this case you can observe in the figure given in the exercise, that the the cylinder (which is the three dimensional body) is sliced perpendicular to its base.
By definition , when a plane intersects a cylinder perpendicular to its base, the resulting shape obtained is a Rectangle.
A Rectangle is defined as a quadrilateral whose opposite sides are parallel and have equal lengt. And each angle measures 90 degrees (Angles that measure 90 degrees are also called "Right angles").
To see this better, you can see the picture attached.

Answer:
Option B is correct.
Initial amount (a) = 30 and growth factor(b) = 8.3
Step-by-step explanation:
An exponential function is of the form: ....[1]
where
a represents the initial amount
b represents the growth factor and x is the variable
Given the function:
On comparing given equation with [1] we get;
a = 30 and b = 8.3
Therefore, the initial amount(a) = 30 and growth factor(b) = 8.3
