Answer:
(-2, -2.5)
Step-by-step explanation:
There are an infinite number of such points. One of the easiest to write coordinates for is the one that is on the same horizontal line. Its x-value will be 4 less that that of Q.
(-2, -2.5) is one such point
_____
<em>Additional comment</em>
All of the points that could be solutions are on that portion of a circle with radius 4 and center Q that lies in quadrant III. They make up the red arc in the attachment.
Answer:
Step-by-step explanation:
This is a quadratic equation. We'll find the discriminant, but must first rewrite this equation in standard form:
5w2 – 2w + 4 = -4 + 4, or 5w^2 - 2w + 4 = 0
The coefficients of the w terms are {5, -2, 4}
and so the discriminant b^2 - 4ac is 4 - 4(5)(20) = -396
Because the discriminant is negative, we know that there will be two unequal, complex solutions.
Let A = {Dirk, Johan, Frans, Sarie}, B = {Frans, Sarie, Tina, Klaas, Henrika}, C = {Hans, Frans}. Find the number indicated. n(A

Answer:
Step-by-step explanation:
Given,
A = { Dirk , Johan , Frans , Sarie }
B = { Frans , Sarie , Tina , Klass , Henrika }
To find : n ( A ) + n ( A )
Now, count the number of member of a set A
n ( A ) = 4
Also, Count the number of members of a set B
n ( B ) = 5
<u>Finding </u><u>n</u><u>(</u><u> </u><u>A</u><u> </u><u>)</u><u> </u><u>+</u><u> </u><u>n</u><u> </u><u>(</u><u> </u><u>B</u><u> </u><u>)</u>
= 4 + 5
= 9

14 = 20 - 6
You just plug the numbers in the equation and go from there. Or you can take 14 + 6 and get your number
