Answer:
$2,226.96
Step-by-step explanation:
You are going to want to use the compound interest formula, which is shown below.
<em>P = initial balance
</em>
<em>r = interest rate
</em>
<em>n = number of times compounded annually
</em>
<em>t = time
</em>

First, change 10% into its decimal form:
10% -> 
-> 0.1
Now lets plug in the values into the equation:
The final amount after 15 years is $2,226.96
644 divided by (8 x 8) (8x8) equals 61 so 644 divided 61 equals <span>10.557377049</span>
A₅ = 1/16 and r= 1/4
Let see how to build up this formula that is going to give that term of rank n
1st term =a₁ = To be calculated
1st a₁ = a₁ x r°
2nd a₂ = a₁ x r¹
3rd a₃ = a₁ x r²
4th a₄ = a₁ x r³
5th a₅ = a₁ x r⁴
.......................
.......................
nth : a(n) = a₁ x r⁽ⁿ-¹)
Note when that the subscript of a is the same as the exponent mines 1
We know the ratio r =1/4 & the fifth term, a₅ =1/16 (given). Now let's apply the formula to calculate the unknown a₁.
a(n) = a₁ x r⁽ⁿ-¹) ==>a₅ = a₁ x (1/4)⁽⁵⁺¹⁾ ===> 1/16 = a₁ x (1/4)⁴
1/167 = a₁ (1/256) ==> a₁ =16 & the formula becomes
a₅ = 16(1/4)⁴
7-63.92.28 is the answer hopes this helps
<u>Answer-</u>
<em>The line equation is,</em>
<u>Solution-</u>
The line 
meets x-axis at the point M, i.e M is the x-intercept of this line. At the x-intercept y=0, so
So, coordinate of M is 
The line 
meets y-axis at point N, i.e N is the y-intercept of this line. At the y-intercept x=0, so
So, coordinate of N is 
The line joining M and N can be found out by applying two point formula of straight line,
As it is given that all the coefficients are integers, so multiplying with 3
