Answer:
Shares of Igor Stravinsky car tires in United state = 8%
Shares of Igor Stravinsky truck tires in United state = 46.15%
Step-by-step explanation:
We have given,
Approximate yearly sales of Igor Stravinsky car tires = 3,760,000
Approximate yearly sales of Igor Stravinsky truck tires = 1,200,000
Also,
Every year about 47,000,000 care tires and 26,000,00 truck tires are sold in the United States.
Shares of Igor Stravinsky car tires in United state = = 8%
Shares of Igor Stravinsky truck tires in United state = = 46.15%

Answer:
A
Step-by-step explanation:
The base of a solid in the region enclosed by the graphs of <em>y</em> = eˣ, <em>y</em> = 0, <em>x </em>= 0, and <em>x</em> = 1. Each cross-section perpendicular to the <em>x</em>-axis is an equilateral triangle. We want to find the volume of the solid.
Please refer to the graph below. We are concerned with the red region.
In order to find the volume, we essentially sum up the area of the figure at each <em>x</em> value. So, we integrate from <em>x </em> = 0 to <em>x </em>= 1.
The area for an equilateral triangle is given by:
Where <em>s</em> is the side length of the triangle.
Since the triangle lies perpendicular on the region, the side length of the triangle at <em>x</em> is simply <em>y</em>, which is eˣ.
Therefore, our volume is:
Substitute:
Evaluate the integral. Simplify:
Integrate using u-substitution:
Evaluate:
Therefore, the volume of the solid is:
Our answer is A.
