Answer:

None of the option

Step-by-step explanation:

Given :

(7-3i)+ $(x-2i)^{2} -(4i^{2} +x^{2} )$

(7-3i)+( $x^{2}$ +4 $i^{2}$ -4xi)-(-4+ $x^{2}$ ) Since, $i^{2} =-1$

(7-3i)+ $x^{2}$ -4-4xi +4- $x^{2}$

7-3i-4xi

7-i(3+4x)

Therefore, None of the option is correct.

Timmy estimated he would spend $9 at the candy store. He went a little over-budget and spent $12. What was the percent error?

kap26 [50]

<h2>Answer :</h2>

Error (e) = 12 - 9 = $ 3

assumed value (a) = $ 9

$\boxed{ \mathrm{ \% \: error = \dfrac{error}{assumed \: value} \times 100}}$

$\mathrm{ \% \: error =\dfrac{3}{9} ×100}$

$\mathrm{ \% \: error = \dfrac{1}{3} ×100}$

$\mathrm{ \% \: error = 33.33 \%}$

Which exponential equation is equivalent to the logarithmic equation below? c = ln 2

Sophie [7]

$\text{A logarithmic lemma: } \\ \text{It follows that: } \log_a a = 1$
$\text{Following this property, we can see that: } a^{\log_{a} a} = a$
$\text{Furthermore, we can create more general properties: } a^{\log_a b} = b$

$c = \log_e 2 \Rightarrow e^{c} = e^{\log_e 2} \\ \text{Using our third property, we see that: } e^{c} = 2$
$\text{And finally, this works for any } \log_{a} b \left\{a > 0, b \in \mathbb{R}\right\}$
