If you're confused with a concept or topic, I highly suggest asking questions whether its your friend or of course emailing your teacher. Stay persistent with your work, don't fall behind because speaking from experience, it's horrible trying to come up from it. Take notes, a lot of them too.

If an airplanes speed is 850mi/h what is it’s speed in m/s

Blizzard [7]

we are given

speed is 850mi/h

we know that

1 mile =1609.34 metre

1 hour = 3600 second

now, we can replace 1mi and 1hour

$850mi/h=850*\frac{1609.34}{3600} m/s$

now, we can solve it

379.98306

$850mi/h=379.98306 m/s$ ...........Answer

Find f'(x) and state the domain of f': f(x) = In (2x^2+1)

-Dominant- [34]

Answer:

$f'(x) = \frac{4x}{2x^2+1}$

Domain: All Real Numbers

General Formulas and Concepts:

Algebra I

Domain is the set of x-values that can be inputted into function f(x)

Calculus

The derivative of a constant is equal to 0

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Chain Rule: $\frac{d}{dx}[f(g(x))] =f'(g(x)) \cdot g'(x)$

Derivative: $\frac{d}{dx} [ln(u)] = \frac{u'}{u}$

Step-by-step explanation:

Step 1: Define

f(x) = ln(2x² + 1)

Step 2: Differentiate

Derivative ln(u) [Chain Rule/Basic Power]: $f'(x) = \frac{1}{2x^2+1} \cdot 2 \cdot 2x^{2-1}$
Simplify: $f'(x) = \frac{1}{2x^2+1} \cdot 4x$
Multiply: $f'(x) = \frac{4x}{2x^2+1}$

Step 3: Domain

We know that we would have issues in the denominator when we have a rational expression. However, we can see that the denominator would never equal 0.

Therefore, our domain would be all real numbers.

We can also graph the differential function to analyze the domain.
