The situation is represented by a drawing with a right triangle where an airplane is at the top corner, the elevation angle (opposite to the airplane) is 70°, the height (vertical leg) is x, and the adjacent leg (horizontal leg) to the 70° angle is 800.
Then, to find the height x, which is the opposite leg to the angle, you can use the tangent ratio, which is opposite leg divided by adjacent leg:
tan(x) = opposite leg / adjacent leg => tan(70°) = x / 800
Answer: tan(70°) = x / 800
D1 = 60 for a price of $80. Charging $80 will ensure supply exceeds demand.
___
The store apparently could charge a price slightly lower than $80, but we cannot tell from the chart how much lower.

its C

Answer:
if the absolute terms in the expansion of (x2+k )12 is 495 find the value of k
x
Step-by-step explanation:
First you need to rearrange the equation so both numbers are on the same side :
x - 2y = -1
3x - 3y = 9
then times to mark out x or y
3x -6y = -3
3x -3y = 9
then minus them
-3y = -12
y = 4 x = 7
