Answer:
the circumference of the dics is 62.8cm
Step-by-step explanation:
Answer:
6x−12x^2
Step-by-step explanation:
To calculate amount accrued after a given period of time we use the compound interest formula: A= P(1+r/100)∧n where A i the amount, P is the principal amount, r is the rate of interest and n is the interest period.
In the first part; A= $ 675.54, r= 1.25% (compounded semi-annually) and n =22 ( 11 years ), hence, 675.54 = P( 1.0125)∧22
= 675.54= 1.314P
P= $ 514.109 , therefore the principal amount was $ 514 (to nearest dollar)
Part 2
principal amount (p)= $ 541, rate (r) = 1.2 % (compounded twice a year thus rate for one half will be 2.4/2) and the interest period (n)= 34 (17 years×2)
Amount= 541 (1.012)∧34
= 541 ×1.5
= $ 811.5
Therefore, the account balance after $ 811.5.
Basically, shift each coordinate one unit to the right (one X over)
You will have to predict the points a little
Answer: -4n3+12n2+7n-9
Step-by-step explanation: it basically the opposite sign (positive or negative) switched, and the order backwards. hope that helped
