The measure of central angle XYZ is 1.25 radians. What is the area of the shaded sector?

galben [10]

A sector is the area bounded by two radii and the included arc.
To calculate for the area of the sector, you’ll use the formula A=n/360(pi)(radius) $^{2}$ .
The n in the formula refers to the measure of the central angle in degrees.
The given data in the problem is in radians, convert it by multiplying 1.25 by $\frac{180}{ \pi }$ .
Now input the converted value to the formula of finding the area of the sector.<span>

Use the remainder Theorem and synthetic division to find p(3) for p(x) = x4 + x3 -x2 - 2x

maxonik [38]

You do not need to use the remainder theorem to find p(3). Just plugin 3 where the x is located in

$x^4 + x^3 - x^2 - 2x$

$3^4 + 3^3 - 3^2 - 2(3) = 93$

Answer is a.

To buy a car, you borrow $25,000 with a term of three years at an APR of 6.5%. What is your monthly

Finger [1]

Answer:

$766.23

Step-by-step explanation:

The amortization formula is appropriate for this. (Better, use a financial calculator or spreadsheet.)

A = P(r/12)/(1 -(1 +r/12)^-(12t))

where P is the amount borrowed (25,000), r is the annual rate (0.065), and t is the number of years (3).

Putting the given numbers into the formula, we have ...

A = $25,000(0.065/12)/(1 -(1 +0.065/12)^(-36))

A = $25,000(.00541667)/(1 -1.00541667^-36)

A = $25,000(0.00541667)/(0.1767322)

A = $766.23

The monthly payment is $766.23.

A graphing or scientific calculator is useful for these. Something like a TI-84, or any of the equivalents, will have financial calculations like this built in. There are also numerous apps available for phone or tablet that will do financial calculations.
