If the diameter of a circle changes from 18 cm to 6 cm, how will the circumference change?
omeli [17]
We know that 

the length of a circumference=2*pi*r
for D1=18 cm--------------> r1=9cm
L1=2pi*9-------> 18pi cm

for D2=6 cm-----------> r2=3 cm
L2=2pi*3-------> 6pi cm

L2/L1----------> (6pi)/(18pi)---->1/3

the answer is the option A) multiplies by 1/3

Perform the indicated operation to write given polynomial in standard form: (x^2+ 7x − 12)(x^2 − 9x +1)
Ksivusya [100]

Answer:

The expression in standard form will be x^4=2x^3-50x^2+115x-12      

Step-by-step explanation:

We have given polynomial (x^2+7x-12)(x^2-9x+1)

We have to write the given polynomial in standard form

For writing in standard form we have to first multiply then write in order

So after multiplication

(x^2+7x-12)(x^2-9x+1)=x^4-9x^3+x^2+7x^3-63x^2+7x-12x^2+108x-12=x^4=2x^3-50x^2+115x-12

So the expression in standard form will be x^4=2x^3-50x^2+115x-12
