Given z=4+3i evaluate z

DerKrebs [107]

Answer:

Step-by-step explanation:

Assuming we want to evaluate |z|, given that, z=4+3i.

Then, by definition of modulus,

$|x + yi| = \sqrt{ {x}^{2} + {y}^{2} }$

$|4+ 3i| = \sqrt{ {4}^{2} + {3}^{2} }$

$|4+ 3i| = \sqrt{ 16+ 9 } \\ |4+ 3i| = \sqrt{25 } \\ |4+ 3i| = 5$

Therefore the modulus be of the given complex number is 5 units

Write three fractions that are equivalent to 3 over 11 , but written in higher terms. One of them must

Alinara [238K]

Answer:

Three fractions that are equivalent to $\frac{3}{11}$ are: $\frac{6}{22}$ , $\frac{24}{88}$ and $\frac{144}{528}$ .

Step-by-step explanation:

Equivalent fractions are set of fractions in which when simplified, they have the same answer.

Given: $\frac{3}{11}$

i. multiply the numerator and denominator of $\frac{3}{11}$ by 2,

= $\frac{3*2}{11*2}$ = $\frac{6}{22}$

i. multiply both the numerator and denominator of $\frac{6}{22}$ by 4,

= $\frac{6*4}{22*4}$ = $\frac{24}{88}$

ii. multiply the numerator and denominator of $\frac{24}{88}$ by 6,

= $\frac{24*6}{88*6}$ = $\frac{144}{528}$

So that;

$\frac{3}{11}$ = $\frac{6}{22}$ = $\frac{24}{88}$ = $\frac{144}{528}$ .

Three fractions that are equivalent to $\frac{3}{11}$ are: $\frac{6}{22}$ , $\frac{24}{88}$ and $\frac{144}{528}$ .
