Simplify 1/4-7i to get a complex number in standard a + bi form.

Romashka [77]

Answer:

$\frac{1}{4-7i}=\frac{4}{65}+\frac{7}{65}i$

Step-by-step explanation:

we are given

$\frac{1}{4-7i}$

Firstly, we will get rid of imaginary term from denominator

so, we will multiply conjugate to both top and bottom term

$\frac{1}{4-7i}=\frac{1\times (4+7i)}{(4-7i)\times (4+7i)}$

$\frac{1}{4-7i}=\frac{4+7i}{4^2-(7i)^2}$

$\frac{1}{4-7i}=\frac{4+7i}{16+49}$

$\frac{1}{4-7i}=\frac{4+7i}{65}$

we can also write as

so, we get

$\frac{1}{4-7i}=\frac{4}{65}+\frac{7}{65}i$

the sales tax in bill's state is 6%. bill bought a scion having a sales tax of $820. what was the cost of the car? round to the

polet [3.4K]

Since there is a sales tax of 6% which was equal to $820

Let the value be = x

6% of x = 820

(6/100)x = 820

0.06x = 820

x = 820/0.06

x = 13666.67

Value to the nearest dollar ≈ $13 666.67

The strategy is called expanding notation because you are expanding that problem into small equations :)
