Step-by-step explanation:
Hypotenuse : Opposite the right angle.
Opposite : Opposite the angle.
Adjacent : the last side left.
Your formulas.
Soh Cah Toa (Sin Cos Tan)
You'll be using Cos (Cah) because hypotenuse and adjacent are the only sides with something in it.
You rearranged formula :
Side length × Cos (Angle) = your answer to x
Answer:
f(x)=(x-6)(x-(-7))
Step-by-step explanation:
Foiled:
0 = x + x - 42
Your question is too general. You might ask instead, "how do I simplify the radical sqrt(48)?"
sqrt(48) can b e simplified by rewriting 48 as the product of the perfect square 16 and the not-a-perfect-square 3:
sqrt(48) = sqrt(16)*sqrt(3) = 4*sqrt(3) (answer)
In #76, rearrange the terms so that you have 3sqrt(7x+4)=15. Then divide both sides by 3, obtaining sqrt(7x+4) =5. Squaring both sides: 7x+4=25.
Solve this linear equation for x.
Answer:
17
Step-by-step explanation:
a^2 + b^2 = c^2
a^2 = 8^2 = 64
b^2 = 15^2 = 225
64 + 225 = 289
c^2 = 289
c = Square root of 278
c = 17
Answer:
Alcohol
Step-by-step explanation:
Alcohol would be more suitable for making measurements in a -60 degree laboratory, since its boiling point is 78 degrees and its freezing point is -80 degrees, meaning alcohol will not freeze in a -60 degree environment.
Mercury on the other hand, has a freezing point of -39. Thus, it will freeze in a -60 degree environment, making it not suitable for use in this laboratory.
