Simplify: 5 - i8 + 2i32

1 answer:

5 0

So when writing non-real numbers you must put it into a+bi format where a is the real part and bi is the non-real part so
if we assume that 2i32=2*32i=64i
then the closed phrase is
5-8i+64i
or
5+56i

Find the distance between points (0,-8) and (3,-2)

kompoz [17]

$\bf~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{0}~,~\stackrel{y_1}{-8})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{-2})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ d=\sqrt{[3-0]^2+[-2-(-8)]^2}\implies d=\sqrt{(3-0)^2+(-2+8)^2} \\\\\\ d=\sqrt{3^2+6^2}\implies d = \sqrt{9+36}\implies d=\sqrt{45}\implies d\approx 6.71$

Which sum is equivalent to 7/9 + 5/6?

matrenka [14]

Answer:

The Answer is 29/18 and in mixed form it is 1 11/18

Step-by-step explanation:

Steps for adding fractions

Find the least common denominator or LCM of the two denominators:

LCM of 9 and 6 is 18

Next, find the equivalent fraction of both fractional numbers with denominator 18

For the 1st fraction, since 9 × 2 = 18,

7 × 2

9 × 2

Likewise, for the 2nd fraction, since 6 × 3 = 18,

5 × 3

6 × 3

Add the two like fractions:

14 + 15

= 29/18

So, 7/9 + 5/6 = 29/18

In mixed form: 1 11/18
