Answer: The correct option is

(C) irrational because it is a non-terminating and non-repeating decimal.

Step-by-step explanation: We are to select the correct statement for the following number:

$n=4.5+3.14159265359~.~.~.$

Rational number: a number is said to be rational if the digits after the decimal are either terminating or repeating.

Irrational number: a number is said to be irrational if the digits after the decimal are non-terminating and non-repeating.

Given number is

$n=4.5+3.14159265359~.~.~.=7.64159265359~.~.~.$

Since the digits after the decimal and neither terminating nor repeating, so the given number is IRRATIONAL.

Thus, the number is irrational because it is a non-terminating and non-repeating decimal.

Option (C) is CORRECT.

So this question you just add..... but this is irrational because it does not terminate meaning the decimal doesnt end home this helped have an amazing day!

Jade invested $13,500 at 5.2% interest, compounded semiannually, and she wants to know how much her investment will be worth in

rodikova [14]

Part 1: What is the periodic interest rate of jade investment?

Each compounding period is done semi-annually, which means twice a year. Since the given interest rate is annual, then 5.2% divided by half should yield the period interest rate, which is 2.6%

Part 2: How many compounding periods does Jade's investment offer in a year? how about in 8 years?

In 1 year, there are 2 compounding periods. In 2 years, there are 16 compounding periods.

Find the area use 3.14 for pi

Aleonysh [2.5K]

Answer:

15.14 cm^2

Step-by-step explanation:

Area of rectangle = 4cm x 3 cm = 12cm^2

Radius of the circle = 2 cm

Area of 1/4 of a circle = (pi x r^2) / 4

= (3.14 x 4) / 4 = 3.14 cm^2

3.14 cm^2 + 12cm^2 = 15.14 cm^2

An isosceles trapezoid ABCD with height 2 units has all its vertices on the parabola y=a(x+1)(x−5). What is the value of a, if p

horrorfan [7]

Answer:

a = -0.3575

Step-by-step explanation:

The points A and D lie on the x-axis, this means that they are the x-intercepts of the parabola, and therefore we can find their location.

The points A and B are located where

$y=a(x+1)(x-5)=0$

This gives

$x=-1$

$y=5$

Now given the coordinates of A, we are in position to find the coordinates of the point B. Point B must have y coordinate of y=2 (because the base of the trapezoid is at y=0), and the x coordinate of B, looking at the figure, must be x coordinate of A plus horizontal distance between A and B, i.e

$B_x=A_x+\frac{2}{tan(60)} =-1+\frac{2\sqrt{3} }{3}$
