It is true because every term is the previous term multiplied by -2. So, -40 x -2 = 80, 80 x -2 = -160
Answer:
4
Step-by-step explanation:
First off, integers are Whole Numbers (1,2,3,4, etc), so we are rounding the answer to the nearest whole number.
The square root of lets just say 25 means you are finding a number that multiplied by itself will equal 25 (the answer is 5).
Now for 13, there is no perfect square, however the closest whole number that multiplied by itself to 13 is 4.
4*4= 16
3*3=9
5*5=25
As you can see above 4 is the closest number to 13.
Now, the ACTUAL value of the square root of 13 is 3.60555128, but we are rounding up to the nearest whole number which is 4 :)
The geometric sequence is 24,12,6,3, and then 0
Answer:
Hope you got it....
Step-by-step explanation:
1=tan45∘
1=tan(22∘+23∘)
1=tan22∘+tan23∘1−tan22∘tan23∘
1−tan22∘tan23∘=tan22∘+tan23∘
1=tan22∘+tan23∘+tan22∘tan23∘
It will be the same for any two angles that add up to 45∘.
Answer:
x = - 
Step-by-step explanation:
Given
(x - 9) = - 11
Multiply both sides by 3 to clear the fraction
2(x - 9) = - 33 ← distribute left side
2x - 18 = - 33 ( add 18 to both sides )
2x = - 15 ( divide both sides by 2 )
x = -
