6i/ (1+i)

multiply by the complex conjugate (1-i)/(1-i)

6i/(1+i) * (1-i)/(1-i)

6i* (1-i) = 6i - 6i^2 = 6i - 6(-1) = 6i +6

(1+i)*(1-i)= 1-i +i -i^2 = 1 -i+i -(-1) = 1+1=2

(6+6i)/2

$\text{Hey there!}$

$\bf{9.83+8.2(7.01)}$

$\text{You could solved this equation by doing PEMDAS}$

$\text{PEMDAS simply means}\downarrow$

$\text{Parentheses }$

$\text{Exponents}$

$\text{Multiplication}$

$\text{Division}$

$\text{Addition}$

$\text{Subtraction}$

$\text{In your equation you have \bf{MULTIPLICATION \& ADDITION}}$

$\text{Now, that we have every information we need.. lets solve the problem}$

$\text{We have to do \underline{MULITPLICATION} first then \underline{ADDITION} last}$

$\text{9.83 + 8.2(7.01)}$

$\text{8.2(7.01)=57.482}$

$\text{9.83 + 57.482 = 67.312}$

$\boxed{\boxed{\text{Thus your answer is most likely: \bf{67.312}}}}\checkmark$

$\text{Good luck on your assignment and enjoy your day!}$

Answer:

Step-by-step explanation:

Since we are not given the value of P, |Q|, R and S, we can as well assume values for them for the sake of this question.

Let P = 5, |Q| = 6, R =7 |S| = 2

Note that since Q and S are in modulus sign, they can return both positive and negative values.

P+Q = 5 + 6 (note that the positive value of Q is used since we need the greatest value of P+Q)

P+Q = 11

Hence the greatest value of P+Q is 11

For the least value of P+Q, we will use the negative value of Q as shown

P+Q = 5+(-6)

P+Q = 5-6

P+Q = -1

Hence the least value of P+Q is -1

Similarly:

R+S = 7 + 2 (note that the positive value of S is used since we need the greatest value of R+S)

R+S = 9

Hence the greatest value of R+S is 9

For the least value of R+S, we will use the negative value of S as shown

R+S = 5+(-2)

R+S = 5-3

R+S = 2

Hence the least value of P+Q is 2

NOTE THAT THIS ARE ASSUMED VALUES. ALL YOU NEED IS TO PLUG IN THE VALUES OF P, Q and R THAT YOU HAVE IN CASE THE VALUES DIFFERS.

Anika [276]

Answer:

1096 more water

Step-by-step explanation:

Let;

x = the water used in general

but used 3 times of the original = 3x

3*(548) = 1644 water a day

How much more water =New - original

where:

new = 1644

original= 548

1644 - 548

=1096 more water

Answer:

45 − x % ∗ 45 = 38.25

− 45 x /100 = 38.25 − 45

− 45 x /100 = − 6.75

x = 6.75 ∗ 100 /45

= 15
