The radius of the circle above is 34 mm. What is the circumference of the circle? (Use 7 = 3.14.)

1 answer:

7 0

213.52 mm because you have to use the formula (c=2*pi*r). First, you multiply 2 by 3.14, which is 6.28. Then, you multiply 6.28 by the radius,34, and you get 213.52 mm. Hope this helped!!!

A segment in the complex plane has a midpoint at 3 – 2i. If one endpoint of the segment is at 7 i, what is the other endpoint? –

Brut [27]

The midpoint of a segment divides the segment into equal halves

The other endpoint is 1- 5i

<h3>How to determine the missing endpoint </h3>

The coordinates are given as:

Point 1: 7 + i

Midpoint: 3 - 2i

Represent the other endpoint with x.

So, we have:

2 * Midpoint = Point 1 + x

This gives

$2 * (3 - 2i) =7 + i + x$

$6 - 4i =7 + i + x$

Collect like terms

$x = 6 -7- 4i -i$

Evaluate the like terms

$x = 1- 5i$

Hence, the other endpoint is 1- 5i

Explain which variables would be included when using technology to calculate the present value of a lump sum and to calculate th

koban [17]

Answer:

a. Present value of a lump sum =

PV = FV / ( 1 + i )ⁿ

b. Present value of an annuity =

P = PMT x ((1 – (1 / (1 + r)⁻ⁿ )) / r)

Step-by-step explanation:

a. Present Value of a Lump sum =

PV = FV / ( 1 + i )ⁿ

Where variables in the formula are explained as follows

PV = Present Value of the given amount today

FV = Future Value of the given amount

i = Discount rate

n = Number of periods

b. Present value of an annuity is given as:

P = PMT x ((1 – (1 / (1 + r)⁻ⁿ)) / r)

The variables in the equation are explained as the follows:

P = the present value of annuity

PMT = Payment per period or the amount in each annuity payment

r = the interest or discount rate

n = total number of periods or the number of payments left to receive
