The answer is
3x = 2x + 6
Answer: -2 F
Step-by-step explanation:
To find the average, or <em>mean, </em>of a data set, you must first combine all of the values in the set. Since some of these values are negative, it seems more difficult to solve. But it isn't. To find the mean of any data sets, you can find the absolute value of each numerical value. If you combine these regularly, it would be -15, but that is incorrect. The answer is -2 because some of the values may be negative, but you can find the answer easily. Just remember: To find the mean of data sets with negative values, you can find their absolute values, and solve from there. If this does not work for you, then find another solution. But the correct answer is -2 F.
Answer:
The third one
Step-by-step explanation:
Since this is looking down on the cubes from above, I feel it is safe to assume that it is the third one.
From left to right, top to bottom:
3, 2, 2
2, 2, 1
2, 2, 1
We can see that all but 3 layers are 2 blocks high. The 3 block area is the top left corner, since it is 1 block higher than the 2 block areas, and the 1 block areas are the middle right and the bottom right areas.
Answer:
Step-by-step explanation:
Given
Cost Price 
Price 
Revenue generated 
where x=no of units
To get maxima and minima differentiate R(x)
maximum Revenue 
(b)Profit=Revenue - cost
differentiate Profit to get maximum value
maximum Profit 
(c)Now company decided to tax the company $ 55 for each set
Profit 
differentiate Profit to get maximum value
company should charge 207.5 $ for each set
We know that
tan²(A)+1 = sec²(A)--------> tan²(A)= sec²(A)-1
tan²(A)= (4/3)²-1------> tan²(A)=16/9-1-----> 7/9
tan²(A)=7/9
if the angle A is in the IV quadrant
then
tan (A) is negative
therefore
tan (A)=-√(7/9)-----> tan (A)=-√7/3
so
cot (A)=1/tan(A)------> cot (A)=-3/√7----> -(3/7)*√7
the answers are
a) the identity is tan²(A)= sec²(A)-1
b) tan (A)=-√7/3
