Answer:
Use the idea of slope here to find the rate of change of contestants since that is what slope is: the average rate of change between two coordinates. This is not linear, so the rate of change for the whole function is not going to be the same as it is between round 2 and round 4. The slope formula using the coordinates from x = 2 to x = 4 is 8 - 128/4 - 2 which gives a slope of -60. This represents the average rate of change of contestants from the second round to the fourth.
Your question is a difference of squares. both terms that need to be factored are squared. to solve take the square root of each put into two terms one of addition and one of subtraction.
anwser= (5x-9)(5x+9)
the reason this works is because when you foil you get
25x²-45x+45x-81
the middle terms cancel revealing
25x²-81
Answer:
Step-by-step explanation:
This is flux problem (see diagram below)
Since electric field is vertical to the top and bottom of the cube. total flux will be sum of flux up and down i-e
Фtotal=Фup + Фdown = Ф 260 + Ф150
But flux is given by scalar product of Electric field and area
Ф=E.A= EA cos∅
where ∅ is the angle between two vector quantities E the electric field and A the area vector. So, total flux is
Фtotal = 
But we know that according to Gausse's Law total flux is given by;
Total flux = q / ∈
==> q= ∈(Total flux)
The degree of this polynomial is 3, so it has to have 3 roots or 3 zeros.
If it has one non-repeated x-intercept, that means that this polynomial has ine real zero.
So, it needs 2 more, and this 2 are complex zero.
Correct answer is B. One real and 2 complex zeroes.
Answer:
36-54i
Step-by-step explanation:
(9+9i)(-1-5i)
v
-9-9×5i-9i-9i×5i
v
-9-45i-9i-45i^2
v
-9-45i-9i-45×(-1)
v
(-9)-45i-9i+(45)
v
36(-45i)(-9i)
v
36-54i
