<span>Use a proportion:
x/(5 1/2) = 50/4
--------
x = (11/2)(50/4)
--------
x = 550/8
----
x = $68.75</span>
Answer: A, B, C, and E
Step-by-step explanation:
If both sides are real numbers, then the product will be a real number.
If in at least one of the sides we have a complex number, then the product will be real if:
The other number is zero.
The other number is the conjugate of the first.
This is when:
Suppose we have a number:
z = a + b*i
The conjugate will be:
w = a - b*i
And the product between them is:
(a + b*i)*(a - b*i) = a^2 + a*b*i - a*b*i + b^2 = a^2 + b^2
Then the options that will have a real answer are:
A. (4+5i)(4-5i) = 4^2 + 5^2 = 16 + 25 = 41
B. (4 + 91)*(41 - 9) = 3040
C. (3 + 2*i)*(3 -2*i) = 3^2 + 2^2 = 9 + 4 = 13
E. (312 + 7i)*(312 - 7i) = 312^2 + 7^2 = 97,393
This is more of a physics question. Basically you have to separate all the given values into x- and y- coordinates. You are given the home (3 miles East)(5 miles up), so the 3 miles would be on the x axis and the 6 miles on the 6 axis
Given that, you can determine the total displacement of the house from the town using Pythagorean’s theorem. You then do the same with the office and then add your 2 resultant answers together.
The home will be square root 34 miles away from the town, and the office will be square root 85 miles. Adding these together, the answer would be
15,05 miles
Meaning that the lawyers home is 15,05 miles from her office (home to office would be in a south western direction)
Answer:
C=−Ax−By
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
