Answer:
A. you can make purchases even when you don't have cash
Step-by-step explanation:
A credit card is used to buy things, you can pay those things when the "cut" of the balance on tour credit card is due, for example there are credita cards that give you a 28 days interests free day and you would have to pay it by the 4th of the next month, no matter when you buy it, for example if you buy a TV on the 25th of july, you have to pay your credit card on the 4th of august so it won´t generate interests, this could help you to buy things when you don´t have cash but you know you´ll have it by the next month.
Answer:
The correct option is C
C) Hungary
Step-by-step explanation:
Suppose we draw a vertical number line such that it shows elevations of different countries. For y=0, we get India. As all the rest of the values, expect Hungary, are given negative values, hence all the value will lie below India in the numbers line. The only country that lies above India in the number line is Hungary as only it has a positive number for the elevation. So the lowest elevation above 0 will be shown of Hungary which is 78.
Answer:
t=0
Step-by-step explanation:
r=<+1,>
by differentiating the r vector component by component
r' = <2at, 1>
Two vector are orthogonal when the dot product between them is zero, so:
r'·r=0
<+1,>·<2at, 1>=2+2at+t=0
common factor
t(+2a+1)=0
Then, the only real value for t is zero.
-> t=0
Answer:
Step-by-step explanation:
Maybe the big numbers make it confusing, so let's look at something simpler. If you start with 5 marbles and every day you add one marble to it how many will you have x days after startign the collection? Well on day 0 it's 5, on day 1 it's 6, because 5+1, on day 2 it's 5+2=7, and so on. You can write this as an equation, y = 5+x, where y is the new total and x is the number of days.
So let's move that thinking to this problem. 1990 is day 0 and you start with 3,500,000. Each year now instead of day you add 38,500. So year 0 has 3,500,000. year 1 has 3,500,000+38,500 = 3,538,500 and so on, where each year we add another 38,500. So just like in the simpler example we can rewrite this. y = 3,500,000 + 38,500x. Linear means that the x is just an x instead of something like x^2, or 1/x or something else. Just normal x.
The numbers that go into 120 are 10,12 and 6,20 and 3,40,. That's all I can think of at the moment.
