<h3><u>Answer </u><u>1</u><u> </u><u>:</u><u>-</u></h3>

If I were one of the students in Barangay then I shall prepare the design of kite by using the known properties of kites in mathematics.

For example, Symmetrical about its main diagonals, Adjacent side equals, Having two pairs of congruent triangle etc.

<h3><u>Answer </u><u>2</u><u> </u><u>:</u><u>-</u><u> </u></h3>

Design of kite assign to me

<u>Step </u><u>1</u><u> </u><u>:</u><u>-</u>

  • I shall take one paper and cut it like that the adjacent sides of paper are equal

<u>Reason </u><u>:</u><u>-</u>

  • <u>Adjacent </u><u>sides </u><u>of </u><u>kite </u><u>are </u><u>equal </u>

<u>Step </u><u>2</u><u> </u><u>:</u><u>-</u>

  • I shall take two thin sticks and paste it on the paper but sticks should intersect each other at 90°

<u>Reason</u><u> </u><u>:</u><u>-</u>

  • <u>Kite</u><u> </u><u>has </u><u>2</u><u> </u><u>diagonals </u><u>which </u><u>intersect </u><u>each </u><u>other </u><u>at </u><u>9</u><u>0</u><u>°</u><u> </u><u>.</u>

<u>Step </u><u>3</u><u> </u><u>:</u><u>-</u>

  • <u>Make </u><u>a </u><u>hole </u><u>in </u><u>the </u><u>one </u><u>of </u><u>the </u><u>end </u><u>point </u><u>of </u><u>a </u><u>longest </u><u>sides</u><u>. </u>

<u>Observation </u><u>:</u><u>-</u>

  • <u>The </u><u>kite </u><u>should </u><u>be </u><u>looked </u><u>like </u><u>that </u><u>it </u><u>having </u><u>two </u><u>pairs </u><u>of </u><u>congruent </u><u>triangle</u><u> </u><u>with </u><u>common </u><u>base. </u>

<h3><u>Answer </u><u>3</u><u> </u><u>:</u><u>-</u></h3>

  • The adjacent sides of the kites are equal that is 4cm and 6cm
  • The diagonals of the kite bisect each other at 90°
  • As kite is symmetrical from main diagonals , so it has two opposite and equal Angles that is 127°
  • The opposite angles at the end points of kite are congruent that is Angle D and Angle C
  • AC is the bisector of AB and AB is the bisector of AC .

[ Note :- Kindly refer the above attachment ]

<h3><u>Answer </u><u>4</u><u> </u><u>:</u><u>-</u></h3>

All mathematical concepts used in making kite are as follows :-

  • <u>Adjacent </u><u>sides </u><u>are </u><u>equal </u>
  • <u>Diagonal </u><u>intersect </u><u>each </u><u>other </u><u>at </u><u>9</u><u>0</u><u>°</u>
  • <u>Having </u><u>two </u><u>pairs </u><u>of </u><u>congruent </u><u>triangle </u><u>with </u><u>common </u><u>base </u>
  • <u>Symmetrical </u><u>about</u><u> </u><u>its </u><u>main </u><u>diagonal</u>
  • <u>Opposite </u><u>angles </u><u>at </u><u>the </u><u>end </u><u>points </u><u>are </u><u>equal</u>

Lenny and Lisa have obtained a 30-year, fixed rate mortgage for $675,250 with a 7.25% interest rate. They purchased 3 points and
Vikentia [17]

Answer:

119 months

Step-by-step explanation:

In this question, we are asked to calculate the amount of time it would take for a break-even point on a mortgage, if there is a factoring in the cost of points.

We proceed to answer the;

Mathematically,

The Break Even Point = Amount Paid for purchasing Discount Points divided by Monthly savings in the interest payments

We lost out the important values given in the question as follows:

Amount of Mortgage - $675,250

Tenure - 30 Years

The Rate of interest without points = 7.25%

The number of points = 3 points

The rate of interest with the 3 points = 6.875%

The amount to be paid for purchasing the discount point is now calculated below;

Since 1 discount point = 1% of mortgage value;

Therefore, 3 discount points = 3% of mortgage value

The amount paid is thus = 3% of $675,250 = $20,257.5

To calculate Monthly payment without points, we use the mathematical formula;

M = P[r(1+r)^n/((1+r)^n)-1)]

Where M

Is monthly payment, r is the interest rate, n is the number of months.

According to the question M = 675,250, r = 7.25% = 7.25/100 = 0.0725 , n= 30 * 12 months = 360 months

M = 675,250[0.0725(0.0725+1)^30/(1+0.0725)^360)-1) = $4606.40

To get the monthly payment with points, we simply use the formula again but this time interest rates will be 6.875% = 0.06875 I.e r = 0.06875

Inputting the terms in the formula will yield a value of $4435.91. This means monthly payment with discount will be $4435.91

Savings in monthly payments after purchasing the discount points = $4,606.40 - $4,435.91 = $170.48

Break Even = Purchase cost of Discount Points / Monthly savings

= $20,257.5 / $170.48

= 119 Months

Hence, the number of months it will take Lisa and Lenny to break-even point on their mortgage will be 119 months
