The base of s is the triangular region with vertices (0,,,1). cross-sections perpendicular to the y-axis are equilateral triangles. find the volume v of this solid.

Step-by-step explanation:

Diagram relating to the given vertices is attached below

height of equilateral triangle is given as

h = s sin60

area of triangle is given as

equation for line of given figure below that representing  diagonal is given as

y = -x + 1

integrate the from 0 to 1 we will have volume value

560

hope this : )

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
