X is 3 because 3 sqaured is 3x3=9
Answer:
3^9 = 19,683
Step-by-step explanation:
The applicable rule of exponents is ...
(a^b)(a^c) = a^(b+c)
__
Then the expression evaluates to ...
3^4 × 3^2 × 3^3 = 3^(4+2+3) = 3^9 = 19683
Answer:
The answer is -1/6
Step-by-step explanation:
-2/3 - (-1/2)
=-2/3+1/2
=-1/6
Answer:
B is only equilateral, everything else is correct.
Step-by-step explanation:
Answer:
The answer to your question is the letter D) 46°
Step-by-step explanation:
Data
length = 25 ft
Opposite side = 18 ft
Angle = Ф
To solve this problem, use trigonometric functions. The trigonometric function that relates the Opposite side and the hypotenuse is sine.
Sin Ф = Opposite side / hypotenuse
-Substitution
sin Ф = 18/25
-Simplification
sin Ф = 0.72
-Result
sin⁻¹ Ф = 0.72 = 46°
