Answer:426m^2
Step-by-step explanation:
Answer:
-13,1
Step-by-step explanation:
f(x)= (x+6)^2-49
When we find the zero's we set f(x) =0
0= (x+6)^2-49
Add 49 to each side
49= (x+6)^2-49+49
49= (x+6)^2
Take the square root of each side
±sqrt(49) = sqrt((x+6)^2)
±7 = (x+6)
Subtract 6 from each side
±7-6 = (x+6-6)
±7-6 = x
7-6 =x -7-6 =x
1=x -13=x
Answer:
At the end of the year, Marc will have 1.10 times the amount invested
Step-by-step explanation:
Let
x -----> the amount that Marc wishes to invested
Remember that
At the end of the year the amount of money will be the amount invested multiplied by 1.10
so
1.10x
therefore
At the end of the year, Marc will have 1.10 times the amount invested
<em>Alternative Method</em>
we know that
The simple interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
substitute in the formula
the answer for x in the question is 6.
