Answer:

You will receive 262,144 pennies after completing the 9th job.

Step-by-step explanation:

Given:

Payment for 1st job = 4 pennies

The payment is quadrupled after this for each job completed.

Payment after 2 jobs = 16 pennies

Payments after 3 jobs = 64 pennies

To find the number of pennies you will receive after the 9th job.

Solution:

Let $a_1$ represent the payment after 1st job.

$a_1=4$

$a_2=16$

$a_3=64$

The sequence is in geometric sequence with common ratio = 4

The n $th$ term of a geometric sequence is given as:

$T_n=a_1r^{(n-1)}$

For the sequence:

$a_1=4$

$n=9$

$r=4$

For the sequence we need the payment after 9th job. So, we are finding $T_9$ .

$T_9=4(4)^{(9-1)}$

$T_9=4(4)^{8}$

$T_9=4(65536)$

$T_9=262144$

Thus, you will receive 262,144 pennies after completing the 9th job.

What is the value of y?

aleksklad [387]

The sum of all the angles of a triangle is 180 degrees. To solve for y you can make a formula of the sum of the angles equal to 180 like so...

y + y + 60 = 180

Now you must combine like terms. This means that first numbers with the same variables (y) must be combined...

y + y + 60 = 180

y + y = 2y

2y + 60 = 180

Now bring 60 to the left side by subtracting 60 to both sides (what you do on one side you must do to the other). Since 60 is being added on the left side, subtraction (the opposite of addition) will cancel it out (make it zero) from the left side and bring it over to the right side.

2y + 60 - 60 = 180 - 60

2y + 0 = 120

2y = 120

Next divide 2 to both sides to finish isolating y. Since 2 is being multiplied by y, division (the opposite of multiplication) will cancel 2 out (in this case it will make 2 one) from the left side and bring it over to the right side.

2y / 2 = 120 / 2

y = 60

Hope this helped!

The amount of money that you will have at the end of the year from your brand-new savings account is $600.69.

<h3>What is future value?</h3>

The future value is the value of periodic cash flows in the future. It can be computed using an online finance calculator as follows:

<h3>Data and Calculations:</h3>

N (# of periods) = 24 (12 X 2)

I/Y (Interest per year) = 0.12% (0.01% X 12)

PV (Present Value) = $0

PMT (Periodic Payment) = $25

Results:

FV = $600.69

Sum of all periodic payments = $600.00 ($25 X 24)

Total Interest = $0.69

Thus, the amount of money that you will have at the end of the year from your brand-new savings account is $600.69.

Two airplanes are are 1600 miles apart and heading toward each other at different altitudes. The first plane is traveling north

Elden [556K]

The planes will pass each other in 1.14 hours.

Why?

To solve the problem, we must remember that since both planes are heading toward each other, the speed to the calculations will be their combined speeds.

The speed will be:

$Speed=PlaneA+PlaneB\\\\Speed=620mph+780mph=1400mph$

Now, calculating the time, we have:

$x=v*t\\\\1600mi=1400mph*t\\\\t=\frac{1600mi}{1400mph}=1.14hours$

Hence, the planes will pass each other in 1.14 hours.

Have a nice day!
