The product of (3+2i) and a complex number is (17+7i)

What is the complex number.

Answers

The question is asking us to find the complex number such that: ( 3 + 2 i ) * x = 17 + 7 i. We know that i^ 2 = - 1. x = ( 17 + 7 i ) / ( 3 + 2 i ) . We have to multiply the numerator and the denominator by ( 3 - 2 i ). Then: x = ( 17 + 7 i ) * ( 3 - 2 i ) / ( 9 - 4 i^2 ) = ( 51 - 34 i + 21 i - 14 i^2 ) / ( 9 + 4 ) = ( 51 + 14 - 13 i ) / 13 = ( 65 - 13 i ) / 13 = 65 / 13 - 13 i / 13 = 5 - i. Answer: The complex number is 5 - i.

x^2 + 8x = 33

-11^2 + 8(-11) = 33

121 - 88 = 33

3^2 + 8(3) = 33

9 + 24 = 33

So the answer is the first one

Hope this helps!

$x^2 + 8x = 33 \n x^2 + 8x + ( (8)/(2))^2 = 33 + ( (8)/(2))^2 \n x^2 + 8x + 16 = 33 + 16 \n (x + 4)^2 = 49 \n x + 4 = \pm 7 \n x = 7 - 4 = 3 \n x = -7 - 4 = -11$

Diep bought a baguette loaf of bread 65 centimeters long. For lunch every afternoon, he cuts 15 centimeters of bread for his sandwich. Diep wants to determine the length of the loaf of bread, l, after d days. What is the equation of the scenario? Is the graph of the equation continuous or discrete?

Answers

Given that the original length of the baguette is 65, and for each day 15 gets cut off, we have the functionl(d) = 65 - 15dwhere d is a positive integer representing the nth day. As a matter of fact, the possible vaalues for d are 0, 1, 2, 3, and 4. Since on the 5th day, there won't be enough baguette anymore. This shows that the function l(d) is not continous since only certain points satisfy the condition.Thus, the function is l(d) = 65 - 15 where {d| 0 ≤ d ≤ 4} and it is discrete.

What is -9.4 simplified?

Answers

Answer: -9 2/5

Step-by-step explanation: To convert -9.4 into a negative mixed number and simplified, you’ll have to leave the negative sign and put the number 9 after the negative sign. Finally, simplify 4/10, which is 2/5. This should leave you with a final result of -9 2/5.
