The account is starting off with 1500, so that will be the start value. Since it is simple interest, it will always be gaining 4 percent of 1500. Let's find 4 percent of 1500.
1500×.04= 60
The account will be growing by $60 every year.
1500+60x=y
X is the number of years. We can find the interest earned by multiplying 5, since that is the number of years we are trying to find, and 60, since that is the interest.
60×5= 300
The interest earned is $300 over 5 years.
Now let's find the balance of the account after 5 years.
1500+ 60(5)=y
1500+300=y
1800=y
The balance of the account will be $1,800 after 5 years.
X=15 and y=6
15-6=9
15+2(6)=27
2(6)=12
Two whole numbers whose least common denominator is 36 could be many different pairs: 1 and 36, 2 and 36, 3 and 36, 4 and 36, 4 and 18, 4 and 9, 6 and 36, 9 and 36, 9 and 12, 12 and 36, 12 and 18, 18 and 36, and lastly 36 and 36.
If you want fractions in simplest form, with different denominators, and with an LCD of 36, I would go with 4/5 and 9/13.
I think the reason these work is because 5, 13, and 36 are all pairwise relatively prime (meaning the LCD of any two of them is their product), and because the LCD of 4 and 9 is 36, like I said earlier.
Your answer is 22 x 18 x 9 = 3,564
The x-intercepts of a function is determined by replacing y or f(x) to zero since this is the point of x where it crosses the x-axis (y=0). In this case, for f(x)= sin (x + π/4) , we substitute 0 <span>= sin (x + π/4). sin^-1 of zero is also zero and pi. hence
</span><span>x + π/4 = 0
</span>x = -<span>π/4
</span>x + π/4 = <span>π
x = 3</span><span>π/4</span>
