How do i do perimeter of irregular shapes?

here's an example:
!

Well, because this is a parallelogram, the sides opposite from each other are equal. So we know that the 2 short sides measure 6 , and also that the diameter of that semicircle circle is 6.

By knowing the diameter of the circle, we can figure out the circumference of the circle using the formula C= 2 x Pi x radius.

Once you have the circumference, divide it in half ( because its a half circle) and add that measurement to the perimeter of the parallelogram :

Circumference ( 1/2) + 6 + 6 + 14 + 14 = total perimeter :)

I hope this helped, I can try draw a picture if you need more assistance :)

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
