Here is a pattern of dots.

Mathematics
1 answer:
EleoNora [17]3 years ago
3 0

The dots in the patterns are illustrations of a sequence or progression

  • The number of dots in step 10 is 84
  • The number of dots in step n is (n -1)^2+ 3

<h3>The number of dots in step 10</h3>

From the pattern, we have:

  • Step 0 = 3 dots
  • Step 1 = 4 dots
  • Step 2 = 7 dots
  • Step 3 = 12 dots

So, we have the following pattern

T_n = (n -1)^2+ 3

When n = 10, we have:

T_{10} = (10 -1)^2+ 3

T10 = 84

This means that, there will be 84 dots in step 10 and there will be (n -1)^2+ 3 dots in step n

You have just arranged for a $1,560,000 mortgage to finance the purchase of a large tract of land. the mortgage has an apr of 5.
seraphim [82]
P=1560000
APR=5.6%
monthly interest, i=5.6%/12=7/1500  [fractions keep exact values]
R=1+i=1+7/1500
# of periods, n=30 years = 360 periods
monthly payment, A
A=PR^n(i)/(R^n-1)
=1560000*(1+7/1500)^360*(7/1500)/((1+7/1500)^360-1)
=$8955.632

At the end of eight years,
number of periods, n1 = 8*12 = 96

If paid off at the end of 8 years, value of loan then
future value of principal
F1=PR^n1=1560000*(1+7/1500)^96=2439135.635
future value of payments
F2=A(R^n1-1)/i=8955.632*(1+7/1500)^96-1)/(7/1500)=1081485.620
Therefore the balloon payment
= future value of principal (owing) - future value of payments (paid)
=F1-F2
=2439135.635-1081485.620
=1357650.0152
Round to two places after decimal to get final answer.

Which student correctly used guess and check to determine the unknown number?
Alenkasestr [34]
<h2>Explanation:</h2><h2></h2>

Hello! Remember you need to write complete questions in order to get good and exact answers. Here we know nothing about the students so I can only help you providing the correct steps to find <em>the product of a number and eight is 104:</em>

<em />

Let that number be n, then the statement can be written in a mathematical language as follows:

n\times 8=104 \\ \\ \\ \text{Dividing both sides by 8:} \\ \\ \frac{n\times 8}{8}=\frac{104}{8} \\ \\ \boxed{n=13}

Finally, <em>the unknown number is 13</em>
