The answer for this is 3×4+8÷2=10
Answer:
The correct answer is c. twenty-four years
Step-by-step explanation:
Let suppose Manny place 100 dollars in saving account, than 200 is double of it, so we can easily calculate how long will it take his money to double using growth rate formula.
Growth = (Future value/Present Value)^(1/n) -1
(we have to calculate n that is number of years)
3% = (200/100)^(1/n) -1
1.03 = 2^ (1/n)
Log 1.03 =1/n Log2
1/n = 0.0426
n = 1/0.0426
N= 23.5 years (aprox 24)
The coordinates of the center of this circle will be the average between the extreme points
C = ( (xo+x1)/2 , (yo+y1)/2)
Where,
xo = 3 and x1 = 9
yo = 8 and y1 = 16
Then us stay with"
C = ( (3+9)/2 , (8+16)/2)
C = ( 12/2 , 24/2)
C = ( 6 , 12 )
