Y=2x-3 rise over run and then the y intercept
Use the half angle identity, tan157.5=(1-cos315)/sin315
cos315=cos(-45)=√2/2, sin315=-√2/2
tan157.5=(1-√2/2)/(-√2/2)=(2-√2)/(-√2)=(2√2-2)/(-2)=1-√2
x ^ 2 - 18 = 0
For this case, the first thing you should do is rewrite the expression:
x ^ 2 - 18 = 0
x ^ 2 = 18
The solutions for this case are:
x1 = root (18)
x2 = -raiz (18)
Therefore the answer is:
2 solutions of real numbers.
Answer:
2
Answer: 2
Step-by-step explanation: If the the square and circle have the same area of 12.4, you would need to divide 12.4 by pie or 3.14 to get the diameter. The radius is half the diameter, so you divide the diameter by 2. In this case, 12.4/3.14=3.94. 3.94/2=1.97. You round that up and you get 2
