Answer:
2046
Step-by-step explanation:
The sum of 2^0 to 2^x added is equal to 2^(x+1)-1 but because 2^0 isnt included its 2^11-2 or 2048-2
● 3x^2 - 10 = 0
Add 10 to both sides
● 3x^2 - 10 + 10 = 10
● 3x^2 = 10
Divide both sides by 3
● 3x^2/3 = 10/3
● x^2 = 10/3
● x = √( 10/3 ) or x = - √( 10/3 )
● √(10/3) + (-√(10/3)) = 0
● √(10/3) × -√(10/3) = -10/3
The pattern in the first set of numbers is times 3, to find the next number multiply 54 by 3 to get 162.
The pattern in the second set of numbers is plus 4, to find the next number add 4 to 0 to get 4.
The pattern in the last set of numbers timed -3, to find the next number multiply -81 by -3 to get 243.

Step-by-step explanation:
Identify the opposite, adjacent, and hypotenuse based on the 15 degree angle. From there plug in the variable x and 14 into your tangent equation which would be tan15=x/14. Solve for x using a calculator and your answer would be rounded to 3.8.
