61°
Subtract 90 minus 29. You get 61°
Making sense?
<h3>Answer: 36,400 dollars</h3>
===============================
Work Shown:
Triple each deposit amount as you go from month to month.
100 deposited in January
300 deposited in February
900 deposited in March
2700 deposited in April
8100 deposted in May
24300 deposited in June
Add up those amounts: 100+300+900+2700+8100+24300 = 36,400
---------------
A shortcut is to use the following formula
S = a*(1-r^n)/(1-r)
where
S = sum of the first n terms of a geometric sequence
a = first term = 100 which is the amount deposited in Jan.
r = common ratio = 3 is the idea we triple each deposit
n = number of terms = 6 is the number of months from Jan to June
So we get,
S = a*(1-r^n)/(1-r)
S = 100*(1-3^6)/(1-3)
S = 36,400
which is the same answer as before. This method is much faster if n is large.
Answer:
2·x²+4
Step-by-step explanation:
The sum is an answer to an addition problem and 2 times a number means to multiply by 2. That number is squared so you it's to the second power.
You have to take the x to on side and numbers to the other but in order to do that you'll have to divide -3 from both sides and then just solve the equation.
Answer:
Yes; the compass was kept at the same width to create the arcs for points C and D.
Step-by-step explanation:
When bisecting a segment by hand the steps are:
-Place the compass on one of the endpoints and open the compass to a distance more than halfway across the segment.
-Swing an arc on either side of the segment.
-Keeping the compass at the same width, place the compass on the other endpoint and swing arcs on either side so that they intersect the first two arcs created.
-Mark the intersection points of the arcs and draw a line through those two points.
-The point where this new line crosses the given segment is the midpoint and divides the segment in half.
Its not b because segment c and d was created when you marked the intersection points of the arcs and just drew a line through those two points; They didn't use a straightedge. its not C because this does demonstrate how to bisect a segment by hand, Also the compass was kept at the same width to create the arcs for points C and D. Its not D because this does demonstrate how to bisect a segment by hand, Also a straightedge was not used to create segment CD.
