2 / 5 = 12 / 30

2 / 6 = 10 / 30

12 + 10 = 22

22 / 30 = 11 / 15

4 + 5 = 9

9 and 11 / 15 is your answer

A one-topping pizza costs $15.00. Each additional topping costs $1.25. Let x be the number of additional toppings. You have $20

pantera1 [17]

So,

Our total will be equal to 20. If we want 1 additional topping, we will have an additional $1.25. <span>If we want 2 additional toppings, we will have an additional $2.50. So we can just multiply the number of additional toppings by 1.25 to get the additional amount.

1.25x

However, you will have already spent $15.

1.25x + 15 = 20

This is option B.

P.S. You will be able to put exactly 4 additional toppings.</span>

Sara has 24 sweets

Tresset [83]

<h2>Hello!</h2>

The answer is:

The expression for the number of sweets that Sara and Tim have now, are:

$Sara=(17-x)Sweets\\\\Tim=\frac{(24+x)Sweets}{2}$

To write the expressions for the number of sweets that Sara and Tim have now, we need to follow the next steps:

Sara starts with 24 sweets and Tim starts with 24 sweets

$Sara=24 Sweets\\Tim=24 Sweets$

Then, Sara gives Tim x Sweets

$Sara=(24-x)Sweets\\Tim=(24+x)Sweets$

Then. Sara eats 7 of her Sweets

$Sara=(24-x-7) Sweets\\Sara=(17-x )Sweets\\Tim=(24+x) Sweets$

Then, Tim eats half of his sweets

$Sara=(17-x)Sweets\\\\Tim=\frac{(24+x)Sweets}{2}$

So, the expression for the number of sweets that Sara and Tim have now, are:

$Sara=(17-x) Sweets\\\\Tim=\frac{(24+x)Sweets}{2}$

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

-Dominant- [34]

Answer:

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

Domain: All Real Numbers

General Formulas and Concepts:

<u>Algebra I</u>

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

<u>Calculus</u>

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:

<u>Step 1: Define</u>

f(x) = ln(2x² + 1)

<u>Step 2: Differentiate</u>

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

<u>Step 3: Domain</u>

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.
