Parents wish to have 160,000 available for a child's education. If the child is now 8 years old, how much money must be set as

Ray Of Light [21]

Answer:

$118,791.2985

Step-by-step explanation:

Given that,

A = 160,000

T = 18 - 8 = 10 years

Rate = 3%

since it is semi annual, n = 2

A = P ( 1 + R/2) ∧ 2T

160000 = P ( 1 + 3/2*100) ∧ 2 * 10

160000 = P ( 1 + 3/200) ∧20

160000 = P( 1 + 0.015) ∧20

160000 = P(1.015)∧20

P= 160000/ (1.015)∧20

P = 160000/ 1.3469

= $118,791.2985

Determine which of the lines, if any, are parallel. Explain.

amid [387]

Answer:

Line A and Line C are parallel

Step-by-step explanation:

Slope Equation: $m=\frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

Step 1: Find the slope of the first line

Line a passes through (-1, -2) and (1, 0).

$m = \frac{(0- (-2))}{(1 - (-1))}$

$m=\frac{2}{2}$

$m=1$

Step 2: Find the slope of the second line

Line b passes through (4, 2) and (2, -2).

$m = \frac{(-2- 2)}{(2 - 4)}$

$m = \frac{-4}{-2}$

$m=2$

Step 3: Find the slope of the third line.

Line c passes through (0, 2) and (-1, 1).

$m=\frac{(1-2)}{(-1 - 0)}$

$m=\frac{-1}{-1}$

$m=1$

Answer: Line A and Line C are parallel

the sum of the first n terms of a sequence is 20 - 10 / 2 ^ n - 1 find the sum of the first five terms

Travka [436]

Answer:

$S_5=\dfrac{170}{9}$

Step-by-step explanation:

Given that,

The sum of first n term of a sequence is $S_n=20-\dfrac{10}{2n-1}$

We need to find the sum of the first 5 terms.

Put n = 5,

$S_5=20-\dfrac{10}{2(5)-1}\\\\=20-\dfrac{10}{10-1}\\\\=20-\dfrac{10}{9}\\\\=\dfrac{170}{9}$

So, the sum of first 5 terms is equal to $\dfrac{170}{9}$ .
