Answer:
Step-by-step explanation:
Given two parametric equations 
and 
, the first derivative can be found using the following equation:
In this problem, 
and 
. Finding the derivative of each of these functions with respect to 
gives us the following:
Because , that means the function is a vertical line and has an infinite first derivative.
Answer:
ok so a it' probabily 21 or a number between 1-10
Step-by-step explanation:
First question.We will build up the 3-dimensional object from the dimensions shown in the view above. In doing this, the object is as shown in figure 1. So, we need to find the volume of this object. Let's cut off this object into two objects, so in doing this we can find the whole volume as the sum of the volume in green plus the volume in red (both are cubes), so:
So the answer is G.
Second questionThe answer is D. Let's analyze it:
Given that r represents the radius of the pizza and n the number of slices, so if we substitute r in this equation, then the values for n are:
These are the values of n shown in the table above.
Are the inequalities x > 3 and 3 < x equivalent?
They both say that x must be larger than 3. No bickering here. So yep, they're equivalent.
Inequalities usually have a lot of solutions—in fact, infinitely many. Think about the inequality x > 3. This inequality states that "x must be larger than 3." Any number bigger than 3 is a solution to this inequality. That includes 3.001, 3.0001, 4, 5, 2 million, and every other number bigger than 3. We don't have time at the moment to name them all,
