A square patchwork quilt is to be made with n individual fabric squares in each dimension. Each fabric square will have a side length of 9 inches. There will be a satin border with a width of 3 inches around the perimeter of the finished quilt. Determine an explicit expression in the form A(n)=an2+bn+c for the total area of the quilt, A(n), in square feet, as a function of the number of fabric squares in each dimension.(1 point)

step-by-step explanation:

130 degrees. i have no other way to explain

option b  

step-by-step explanation:

we know that

the distance from point n to lm in the figure is equal to the distance of the perpendicular line to lm that passes through the point n

so

the distance is equal to the segment no

> given problem

therefore

the distance from point n to lm is equal to

answer-

the equation that models this pattern is

solution-

a researcher placed a petri dish with 32,000 bacterial cells. one hour after being placed in the vacuum chamber, the number of cells in the petri dish had halved. another hour later, the number of cells had again halved.

this can be represented as exponential decreasing function,

where,

putting the values,

y-intercept means, where x=0, so

the coordinate of this poin will be (0, 32000)

this means when x=0 or at the starting of the research, the number of bacteria cells was 32000.

after 3 hours, number of bacteria cells will be,

the   coordinate of this point will be (3, 4000)
