Betty decides to set aside $200/month. If her monthly 401(k) savings are earning 5.4% APR compounded monthly, what will the bala
Tatiana [17]

Answer:

(9) $339076.60 (10) $72000 (11) $220800

Note: Kindly find an attached copy of the complete question given below. i solved for 9,10,11 only.

Step-by-step explanation:

Solution

Given that:

Betty set aside $200/month

With a 401 (k) savings

t = 40 years

APR = 5.4%

Now we find the balance in her account after 40 years.

Now,

A = PMT [(1 +r/n)^nt -1]/(r/n)

A = 200 [ (1 + 0.054/12)^(12)(40) - 1]/(0.054/12)

A= $339076.60

(10) Recall that:

t = 40 years

Per month deposit = $150 dollar

The total deposit becomes

t = 40 * 12 = 480 Month

Total deposit = 480 * 150

=$72000

(11) Now we find the less money she received in her paychecks

Thus

Without monthly saving paycheck is =$2300

Now,

For 40 years becomes = $2300 * 40 * 12

=$1,104000

So,

20% of tax deducted = 20/100 * $1,104000

=$220800

Therefore the less amount received in 40 years is $220800

Note:( My research for the complete question was from quiz let, chegg)

The formula for this is m = 4a + 2c, where c = number of children; m = number of meatballs; a = number of adults.

m = (4 x 10) + (2 x 5)
simplify,
40 + 10 = 40
The answer to this is 40 meatballs.

A line segment has endpoints at (8, 3) and (2,5). What would be the equation of this line's perpendicular bisector?
ale4655 [162]

Answer:

y  = −1/3x+17/3

Step-by-step explanation:

The line segment has slope -1/3. This means that any line perpendicular to it will have a slope of 3 (negative reciprocal)

Any line that bisects the line segment will pass through its midpoint. The midpoint is (5,4)

Midpoint formula: ( \frac{x_1+x_2}{2}, \frac{y_1+y_2}{2} )

So perpendicular bisector of this line  is simply a line with slope −1/3 that passes through point (5, 4)

y - 4 = -1/3 (x-5)=

y  =  −1/3x+17/3
