what are the first four terms of the sequence an=n2+4

Answers

Step-by-step explanation:

Given formula

an = n² + 4

Now the first four terms of the sequence are

a1 = 1² + 4 = 5

a2 = 2² + 4 = 4 + 4 = 8

a3 = 3² + 4 = 9 + 4 = 13

a4 = 4² + 4 = 16 + 4 = 20

The terms are

A f(x) = 1,024(1.50)

B f(x) = 1,024(0.50)*

C f(x) = 1,024(1.05)

D f(x) = 1,024(0.50)x

Answer?

Answers

Answer:

1024(0.50)^x

Step-by-step explanation:

Initial value = 1024

Players eliminated per round =half = 50% of players in the round

Using the relation :

A(x) = P(1 - r)^x (decreasing hence, negative)

A(x) = 1024(1 - 50%) ^x

A(x) = 1024(1 - 0.50)^x

A(x) = 1024(0.50)^x

rectangle, trapezium

The second option is faster so lets use that :)

You should draw a dotted line across the top of the rectangle so now there is a rectangle on the bottom and a trapezium on the top!

[tex]A_{square} = b * h\\A_{square} = 16 * 6\\A_{square} = 96m^{2} \\\\\\A_{trap} = \frac{(a + b)h}{2}\\[/tex]

[tex]A_{trap} = \frac{(10 + 16)7}{2}\\\\A_{trap} = \frac{(182)}{2}\\\\A_{trap} = 91 m^{2}[/tex]

A mortgage has an initial balance of $150,000 and is charged 5% yearly interest applied monthly. If a person makes a payment of $1000 each month, which of the following is closest to the mortgage balance after 3 months of payments?

I think it is (2) but I’m not 100% sorry if this wasn’t much help

A mortgage loan is termed as a loan that is used to purchase or maintain a home, land or other pieces of real estate.

The borrower agrees to repay the amount of loan to the lender over a period of time, usually in a series of regular installments divided into principal and interest. The property is used as security for the loan.

Calculation of the amount of mortgage is as follows:

[tex]\text{Interest}= \text{Mortgage amount} \times\frac{0.05}{12}\times3[/tex] = 1875

[tex]\text{Principal Pay }= 1000 \times3[/tex] = 3000

Total amount paid = Interest + principal pay = 1875 + 3000 = 4875

Initial balance = 150000

The remaining balance for the mortgage amount = initial balance - the total amount paid.

Amount of mortgage = $ 145125.

Therefore the closest to the mortgage balance after 3 months of payments is

(1) $145,165.

Hi!! Please explain how you got the answer, thanks!! :)) ​

Answers

Start out by finding the area of the square.

a = 4²

a = 16

Since all we have to look at is 1/4 of this square, multiply the area by 1/4.

(16)1/4

4

The area of the triangle is 4.

Now we need the area of the circle.

a = πr²

Sub: a = π(2)²

a = π(4)

Since the portion of the circle that covers the triangle is 1/4 of the circle, subtract 1/4 of the area of the circle from the area of the circle.

a = 4 - 1/4(π(4))

a = 4 - 1/4π x 1

a = 4 - 1/4π

Now this is where it's supposed to go, considering the fact that π isn't given a value.

Normally, I'd use 3.14 for π, as the entire population would, and then it would be easy, but obviously that isn't an option.

Now this answer isn't up there, so my best option is to tell you it's most likely c, and I hope I'm right.
