Anorman window is rectangular on three sides with a semi-circular top. you decide to install a norman window in your family room with the dimensions indicated in the diagram. what is its perimeter?

a.
15.71 feet
b.
14.23 feet
c.
18.45 feet
d.
14 feet

Option A. Perimeter = 15.71 feet

Step-by-step explanation:

A Norman window is rectangular on three sides with semicircular top.

We have to find the perimeter of the window.

Perimeter of Norman window = perimeter of semicircular top + perimeter of rectangle at the bottom

Perimeter of semicircular top =

                                                 =

                                                 = 4.71 feet

Perimeter of the rectangular base = (Length) + 2(width)

                                                         = 3 + (2×4) = 3 + 8

                                                         = 11 feet

Total perimeter = 4.71 + 11 = 15.71 feet

Answer is Option A.15.71 feet will be the perimeter.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
