The answer is:

$2.45\times 10^5$

Step-by-step explanation:

We are asked to expression the value of the given expression:

$7(3.5\times 10^4)$ in scientific notation.

We know that any number in scientific notation is expressed as:

So the number is written in two parts:

Just the digits (with the decimal point placed after the first digit), followed by × 10 to a power that puts the decimal point where it should be .

Now the value of $7(3.5\times 10^4)$ is:

$7(3.5\times 10^4)=7\times 3.5\times 10^4\\\\7(3.5\times 10^4)=24.5\times 10^4$

in scientific notation the number $24.5\times 10^4$ is expressed as:

$2.45\times 10^5$

Hence, the scientific notation of $7(3.5\times 10^4)$ is:

$2.45\times 10^5$

Fourth and Fifth options are correct.

Step-by-step explanation:

Since we have given two points i.e. A, E, and J

We can see from the graph that

A, E, J are non coplanar and non collinear.

Coplanar means that all the points lie in the same plane.

Collinear means that all the points lie in the same line.

But A, E, and J are neither in the same plane nor in the same line.

Hence, Fourth and Fifth options are correct.
