Answer:
30
Step-by-step explanation:
Solve for n: 0.22n = 6.6.
- 6.6/0.22 (because for example 3/3 and n/n= 1 so 0.22/0.22 = 1 so we have to divide 6.6 since it is part of the equation and we have to do it on both sides.)
- =30
Answer:
Part a)
Part b)
Step-by-step explanation:
we know that
The formula to calculate continuously compounded interest 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 in decimal
t is Number of Time Periods
e is the mathematical constant number
Part a) What is the amount after 2 years?
we have
substitute in the formula above
Part b) How long will it take for the amount to be $8000?
we have
substitute in the formula above and solve for t
Applying ln both sides
Remember that
ln(e)=1
Answer:
Step-by-step explanation:
The square of 2, -2 is 4. square of 3, -3 is 9. so square root of 7 has to be less than 3 but more than 2. therefore the integers are either 2 and 3 or -3 and -2.
Answer:
72
Step-by-step explanation:
One way to do this is to use the formula
where
and
are the lengths of the two diagonals.
In the figure,
and
(2 + 10 and 6 + 6).
The area is
square units.
Another way that doesn't depend on learning a formula is to remember that the diagonals of a kite are perpendicular, so the 4 small triangles are right triangles. Two of the smaller triangles have base =2 and height = 6, so their areas are 1/2(2)(6) = 6. Double that--there are 2 congruent small triangles--to get an area of 12.
There are two larger right triangles with base =10 and height = 6, so their area are 1/2(10)(6)=30. There are two of those, so their combined area is 60.
Finally, put the small triangle area and the large triangle area together to get a total of 12 + 60 = 72
