<u>We have to look for the pattern in the numbers</u>, so we can figure out what the next term in the sequence is !
It looks like,<u> each number is multiplied by 2!</u>
7 × 2 = <em>14 </em>
14 × 2 = <em>28 </em>
So, what's next?
28 × 2 = ?
The next term in the geometric sequence is ... 56!
I hope I helped :)
Comment if you have any confusion !
Answer:
12√3
Step-by-step explanation:
432 is 144 times 3 , and 144 can be written as 12 to the power 2. So, the 144 can just be pulled outside of the radical sign, as a 12 , and the other factor, the 3 , just stays inside of the radical sign.
Or, √432 = 12 √3
Answer:
He must invest R297 521 today.
Step-by-step explanation:
The compound interest formula is given by:

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
Banabas must pay his ex-wife an amount of R350 000 in two years’ time.
This means that 
Interest rate of 8.15% per annum compounded monthly:
This means that
.
Amount he must invest today:
This is P. So




He must invest R297 521 today.
Mathematically, inverse operations are opposite operations. Addition is the opposite of subtraction; division is the opposite of multiplication, and so on. Inverse operations are used to solve simple algebraic equations to more difficult equations that involve exponents, logarithms, and trigonometry.
