Answer:

Principle (P) = $2,512.56 (Approx)

Step-by-step explanation:

Given:

Interest annually (R) = 9.5% = 0.095

Amount need (A) = $9500

Time period (T) = 14 years

Find:

Principle (P)

Computation:

A = P[e^(R*T)]

9,500 = P[e^(0.095 x 14)]

9,500 = P[3.781]

P = 9,500 / 3.781

Principle (P) = $2,512.56 (Approx)

if you draw 35 lines on a piece of paper so that no two lines are parallel to each other and no three lines are concurrent, how

Levart [38]

Answer:

The lines will intersect 595 times.

Step-by-step explanation:

We can do it in 2 methods.

<u>1st method:-</u> Let us count the number of intersections by drawing lines one by one.

1st line - 0 points=0

2nd line- new 1 point=1

3rd line - old 1 point + new 2 points with two old lines = 1+2

4th line - old (1+2) points+ new 3 points= 1+2+3

5th line - old (1+2+3) points + new 4 points=1+2+3+4

Like that from 35th line-1+2+3+4......34 = $\frac{34X35}{2}=595$

<u>2nd method:-</u>

We have to choose 2 lines from 35 lines.

We can do it in $35_{C} _{2}$ ways = 595 points
