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

John and his son are building a boxcar for a group competition. According to the rules of the competition, the length of the car
kozerog [31]

Answer:

x ≥ y + 2

0.50 (x) (x+3) + 2.25 (4) (y) ≤ 50

Step-by-step explanation:

x = width of the car

x+3 = length of the car

y = radius of the car

The width must be at least 2 inches greater than the radius, so:

x ≥ y + 2

The total cost must be no more than $50, so:

0.50 (x) (x+3) + 2.25 (4) (y) ≤ 50

I don't know how to do this please help explain how to do it aswell as give the answer so i understand
Zinaida [17]

<u>We are given:</u>

The function: y = -16t² + 64

where y is the height from ground, t seconds after falling

<u>Part A:</u>

when the droplet would hit the ground, it's height from the ground will be 0

replacing that in the given function:

0 = -16t² + 64

16t² = 64                          [adding 16t² on both sides]

t² = 4                                [dividing both sides by 16]

t = 2 seconds                  [taking square root of both sides]

<u>Part B:</u>

for second droplet,

height from ground = 16 feet

time taken = t seconds

acceleration due to gravity = 10 m/s²

initial velocity = 0 m/s

h = ut + (1/2)at²                 [second equation of motion]

16 = (0)(t) + (1/2)(10)(t²)

16 = 5t²

t² = 16/5

t = 1.8 seconds (approx)

Therefore, the second droplet takes the least amount time to hit the ground

I need help with this equation 20 points help quick
Flura [38]

Answer:

\boxed{y=|\frac{1}{2}x  - \frac{3}{2}|+3}

Step-by-step explanation:

The translation is a horizontal translation.

The graph is translated 1 unit to the left. So the value of x is added by 1.

f(x+1)

y=|\frac{1}{2} (x+1)-2|+3

y=|\frac{1}{2}x + \frac{1}{2} -2|+3

y=|\frac{1}{2}x + - \frac{3}{2}|+3
