Answer:
![g(x) = 6](https://tex.z-dn.net/?f=g%28x%29%20%3D%206)
Step-by-step explanation:
Begin with substuting the x variable with -2, we do this because the question has listed the value of x already.
Using the value of x, -2 we determine g(x).
g(x) = -2^2 + 2
Above is what the equation would look as, after you input the value of -2.
Using pemdas, (parantheses, exponents, multiplication, division, addition, subtraction) solve the equation.
-2^2 = 4
Think of it as -2 * -2, which is why -2^2 is 4.
Add 4 +2.
4 + 2 = 6.
Therefore, the value of g(x) = 6
Answer:
2/5
Step-by-step explanation:
The distance between two points A(u, v) and B(x,y) is given by the equation:
![AB=\sqrt{(y-v)^2+(x-u)^2}](https://tex.z-dn.net/?f=AB%3D%5Csqrt%7B%28y-v%29%5E2%2B%28x-u%29%5E2%7D)
Since point B is at (0, 1), point D is at (5, 1) and point C is at (2, 1)
Therefore the distance between BC and BD is:
![BC=\sqrt{(1-1)^2+(2-0)^2}=\sqrt{4} = 2\\ BD=\sqrt{(1-1)^2+(5-0)^2}=\sqrt{25} = 5](https://tex.z-dn.net/?f=BC%3D%5Csqrt%7B%281-1%29%5E2%2B%282-0%29%5E2%7D%3D%5Csqrt%7B4%7D%20%3D%202%5C%5C%20%20BD%3D%5Csqrt%7B%281-1%29%5E2%2B%285-0%29%5E2%7D%3D%5Csqrt%7B25%7D%20%3D%205)
The ratio between two lines is gotten by dividing their distances by each other.
The ratio of BC to BD is:
Density (D) is the quotient obtained when mass (m) is divided by volume (v).
D = m / v
The volume is the difference of the volume read after and before the object is placed in the beaker,
v = 23.1 mL - 18.5 mL = 4.6 mL
Substituting the known values for the density,
D = 8.24 g / 4.6 mL = 1.79 g/mL
Thus, the density is approximately equal to 1.79 g/mL.
