Answer:
Well.. its already in standard form..
but even if u want u can write it as 8 X 10^(-1)
Step-by-step explanation:
Standard form is used for quite big decimal numbers
like : 0.2356
We can write it as 2.4 X 10^(-1)

The solution points to the system graph are (–2,–4) and (4,8). Therefore, option A is correct.
We need to find the solution to the given function.
<h3>How to find the solution to the function from the graph?</h3>
The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be at the point where the two lines intersect.
From the given graph we can see that the two functions are intersecting at (–2,–4) and (4,8).
The solution points to the system graph are (–2,–4) and (4,8). Therefore, option A is correct.

Answer:
Step-by-step explanation:
y′′ + 4y′ − 21y = 0
The auxiliary equation is given by
m² + 4m - 21 = 0
We solve this using the quadratic formula. So
So, the solution of the equation is
where m₁ = 3 and m₂ = -7.
So,
Also,
Since y(1) = 1 and y'(1) = 0, we substitute them into the equations above. So,
Substituting A into (1) above, we have
Substituting B into A, we have
Substituting A and B into y, we have
So the solution to the differential equation is
