Answer:

(x+8)-x

Step-by-step explanation:

if amy is 8 more than ben

we dont know ben, so he is x

you have to subtract ben from amy

so amy is 8 more than ben, you have to add 8 to ben, who is x

The distance between the two points pictured is d= Vn

katrin [286]

the distance between points is:

d = 7.8 units

d = root ((x2-x1) ^ 2 + (y2-y1) ^ 2)

The ordered pairs are:

(x1, y1) = (- 3, -2)

(x2, y2) = (2,4)

By applying the formula we have:

d = root ((2 - (- 3)) ^ 2 + (4 - (- 2)) ^ 2)

d = root (61)

d = 7.8

Need help with all this

Inessa [10]

✧･ﾟ: *✧･ﾟ:* *:･ﾟ✧*:･ﾟ✧

Hello!

✧･ﾟ: *✧･ﾟ:* *:･ﾟ✧*:･ﾟ✧

❖ To find the mean, add up all the numbers and divide by the amount of numbers there are. To find the range, subtract the highest number by the lowest number in the data set.

2. Mean = 35 Range = 78

3. Mean = 43 Range = 58

4. Mean = 63 Range = 73

5. Mean = 61 Range = 56

6. Mean = 55 Range = 83

7. Mean = 61 Range = 53

8. Mean = 60 Range = 75

9. Mean = 50 Range = 76

10. Mean = 50 Range = 81

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.
