What is halfway between pi and 2pi?

Answers

Answer 1

Answer: We are asked to determine the number that is haflway between pi and 2 pi. to determine the number, we can separate pi and get whats between 1 and 2 (coefficients of pi). The midpoint is 1.5 which is equal to 3/2. Hence, adding pi, the final answer is 3pi/2.

Answer 2

Answer:

Answer:

3π/2 is halfway between π and 2π.

Step-by-step explanation:

We have been asked to find the value that is halfway between π and 2π.

In other words, we have to find the mid value of π and 2π.

This is equal to the average of π and 2π.

Average of two numbers a and b is given by

$\text{Average}=(a+b)/(2)$

a = π, b = 2π

Hence, the average or mid value of the given numbers is

$\text{Mid value}=(\pi+2\pi)/(2)$

Simplifying, we get

$\text{Mid value}=(3\pi)/(2)$

Hence, 3π/2 is halfway between π and 2π.

Step-by-step explanation:

use the formula = a² + 2ab + b²

(9x)² - 2 * 9x * 7xy + (7xy)²

81x² + 49x²y²- 126x²y

Answer:

c) 81x² + 49x²y² - 126x²y

Step-by-step explanation:

when you square something you are multiplying it by itself

(9x - 7xy)² = (9x - 7xy) (9x - 7xy)

this requires the FOIL method:

F = first = (9x)(9x) = 81x²

O = outer = (9x)(-7xy) = -63x²y

I = inner = (-7xy)(9x) = -63x²y

L = last = (-7xy)(-7xy) = 49x²y²

the two middle terms can be combined because they are 'like'

-63x²y + -63x²y = -126x²y

answer:

81x² - 126x²y + 49x²y²

the order is normally changed to be put in decreasing exponent order so 49x²y² is put before -126x²y
