The function f(x) at x = 3 for given the function f(x) = x√(1 - 2x) - 3 so that it becomes continuous at x = 3 is f(3) = 3√(-5) - 3.
We are given the function f(x) = x√(1 - 2x) - 3, to define the function f(x) at x = 3 so that it becomes continuous at x = 3, you need to find the limit of f(x) as x approaches 3. To have a continuous function, the limit of the function as x approaches 3 should be equal to the value of the function at x = 3.
Let's find the limit of f(x) as x approaches 3:
lim (x -> 3) [x√(1 - 2x) - 3]
Substitute x = 3 into the function:
3√(1 - 2(3)) - 3
3√(1 - 6) - 3
3√(-5) - 3
Now, define the function f(x) at x = 3 to be equal to the limit:
f(3) = 3√(-5) - 3
Therefore, the function f(x) is defined at x = 3 as f(3) = 3√(-5) - 3, making it continuous at x = 3.

he distance from Earth to the North Star is about 430 light-years. Which of the following statements describes why scientists use the light-year unit to measure distances in space?
A light-year unit is very small and distances in space are very small.
A light-year unit is very small and distances in space are very large.
A light-year unit is very large and distances in space are very small.
A light-year unit is very large and distances in space are very large.
Answer:
D
Explanation:
because the rest don’t make any sense
A light-year unit is very large and distances in space are very large. Therefore, the correct option is option D.
What is distance?No matter the direction of the journey, distance is the overall path that an item in motion has traveled. Since just the length of the path travelled is calculated as well as the motion's direction is ignored, distance is referred to as a scalar number. The distance can only ever be positive; it can never be 0 or negative.
Displacement generally defined as the overall alteration of an object's location and motion direction. Displacement is recognized as a vector quantity since it takes into consideration both the directions of the motion and the amount of the changing position. Displacement may be zero, positive, or negative. A light-year unit is very large and distances in space are very large.
Therefore, the correct option is option D.

Why Doesn't The Earth Usually Feel Solar Winds?
Answer:
When the solar winds approach the Earth, the magnetosphere (part of the Earth's natural magnetic defenses) deflects/repels most of the charged particles and shields our planet's surface from the winds. Sometimes, however, the magnetosphere isn't strong enough to block the Earth from these winds, so they do hit Earth and may cause catastrophic consequences, such as ruin power grids, cut off telecommunications (cell service/calls), etc.

Our current model of a chemical bond is to think of it as an electrical interaction between what two parts of an atom
Answer:
Explanation:
It involves the thinking of it as an electrical interaction between the positively charged part of an atom and the negatively charged part as well. Succinctly put, the interaction between the proton of an atom and the electron of an atom.
The relationship between these two sub atomic particles is one of the basis for many chemical bonding, and this is inclusive of all the bonds there exist. Hydrogen, Electrovalent and even Covalent bondings to mention but a few
If sodium (Na) bonds with chlorine (Cl), which statement is true?

formed.
An electron is shared between sodium and chlorine and an ionic bond is
formed.
An electron is transferred from sodium to chlorine and a covalent bond is
formed.
An electron is shared between sodium and chlorine and a covalent bond is
formed.
Answer:
First Statement is correct
Explanation:
An electron is transferred from sodium to chlorine and ionic bond is formed.
Hope it help!!
If sodium ( Na ) bonds with chlorine ( Cl ), then an electron is transferred from sodium to chlorine and an ionic bond is formed. Therefore, option A is correct.
What is ionic bond ?The main interaction taking place in ionic compounds is ionic bonding, a form of chemical bonding that includes the electrostatic attraction between two atoms or ions with dramatically differing electronegativities.
When the ionic character is larger than the covalent character, i.e., when there is a significant difference in the electronegativity between the two atoms, the bond is more polar than when the electrons are divided more evenly in covalent bonding.
The ionic bond found in the salt sodium chloride is an illustration of this type of connection. The valence electron from sodium is transported to chloride's outer electron shell.
Thus, option A is correct.
