Answer:

Step-by-step explanation:
we know that

She drove from her house to the airport and back 2 times
so
Multiply the distance from her house to the airport by 4

Answer:
x ≥ 1
Step-by-step explanation:
Since it's a closed circle x could also be equal to 1. Also, since the arrow is pointing away from 1 the answer of x is greater than 1, therefore the answer is x ≥ 1.
The answer is <span>π8^2 or about 201.06</span>
Using the assumed values, the volume of the cone is 
<h3>How to determine the volume of the cone?</h3>
The volume of a cone is calculated using:

The parameters are not given.
So, we use the following assumed values
Radius, r = 5
Height, h =10
Using the assumed values, we have:

Evaluate the product

Hence, using the assumed values, the volume of the cone is

The derivative of sec x is equal to sec x tan x. The derivative of the first derivative can be determined using the rule of products. The derivative is equal to sec x sec^2 x + tan x * sec x tan x. The simplified answer is sec^3 x + sec^2 x tan x equal to sec^2 x ( sec x + tanx )
