Wendy wants $15,000 saved in 6 years to make a down payment on a house. How much money should she invest now at 4.65% compounded

Dahasolnce [82]

A=P(1+R/100)^n
A=$15000, n=6 years, R=4.65
Therefore,
15000=P(1+4.65/100)^6
15000=P(1.3135)
P=15000/1.3135
=$11420 (to the nearest dollars)

Which term of the arthemetic sequence (1, 3, 5, 7) is equal to 141

Dmitry_Shevchenko [17]

Answer:

71th term is 141

Step-by-step explanation:

$a_{1}=1\\\\common \ difference = d = second \ term - first \ term\\\\ = 3 - 1 = 2\\\\a_{n} = 141\\\\a + (n -1)*d = a_{n}$

1 + (n - 1)*2 = 141 {Use distributive property}

1 + 2n - 2 = 141

2n - 1 = 141

2n = 141 + 1

2n = 142

n = 142/2

n = 71

Suppose that the functions s and t are defined for all real numbers x as follows.

Katarina [22]

Answer:

$(s + t)(x)= 5x+1$

$(s - t)(x)= -3x-5$

$(s.t)(1) = -7$

Step-by-step explanation:

Given

$s(x) = x - 2$

$t(x) = 4x + 3$

Solving (a): (s + t)(x)

This is calculated as:

$(s + t)(x)= s(x) + t(x)$

$(s + t)(x)= x-2 + 4x + 3$

Collect like terms

$(s + t)(x)= x+ 4x-2 + 3$

$(s + t)(x)= 5x+1$

Solving (b): (s - t)(x)

This is calculated as:

$(s - t)(x)= s(x) - t(x)$

$(s - t)(x)= x-2 - 4x - 3$

Collect like terms

$(s - t)(x)= x- 4x-2 - 3$

$(s - t)(x)= -3x-5$

Solving (b): (s . t)(1)

First, we calculate (s.t)(x)

This is calculated as:

$(s.t)(x) = s(x)* t(x)$

So, we have:

$(s.t)(x) = (x - 2) * (4x + 3)$

Substitute 1 for x

$(s.t)(1) = (1 - 2) * (4*1 + 3)$

$(s.t)(1) = - 1 * 7$

$(s.t)(1) = -7$
