Answer:
Step-by-step explanation:
we are being told that each square is one unit. so, look at peak to peak and count the units.
1,2,3,4,5,6,7
From peak to peak is 7 units, so the period is 7
Distribute the 5 into the polynomial to get 5a + 5b - a - b. Combine like terms to get 4a + 4b, your answer.
Discount points are normally a type of prepaid interests that lowers the interest on subsequent payments for mortgage borrowers pay.
Each of the points is given by:
1 point = 1% of the mortgage value.
Therefore,
Cost of discount points = 0.01*519,000*3 = $15,570
Cost of origination points = 0.01*519,000*2 = $10,380
In this regard, option B. is the correct answer on the cost of discount and origination points respectively.
One bag of popcorn would cost $6.50
To solve this, we can set up equations:
28p+40c=$282
17p+20c=$160.50
To solve this system, we would need to make either the candy bars the same or the bags of popcorn the same. Since we are solving for bags of popcorn, we will make the candy bars the same:
20(28p+40c=$282)
40(17p+20c=$160.50)
Which would give you:
560p+800c=$5,640
680p+800c=$6,420
Subtract them:
(680p+800c=$6,420)
-(560p+800c=$5,640)
_________________
120p=$780
Now divide by 120 to get the price of one bag of popcorn:
120p=$780
_________
120
p=$6.50
Since the question specifically asks about using a calculator, there's no point explaining how to do it (mostly because the buttons you have to press vary from model to model.
All we can tell you is that the calculator, depending on how many decimal digits it can store, will return something like 0.803802...
Even if there were millions of digits after the decimal point, that would still be an approximate value, since this number is irrational, i.e. it has infinite, non-repeating decimal digits.
