All you have to do is multipy the amount of minutes by 60 seconds because there are 60 seconds in every minute.
35 minutes x 60 seconds
2100 secods

Frank has devised a formula for his catering business that calculates the number of meat balls he needs to prepare the formula i

ira [324]

Answer:

96 meatballs are required

Step-by-step explanation:

We know that the formula for he catering business is

$m=4a+2c$

Where

c= the number of children, m=the number of meat balls, a= the number of adults

So if $c = 8$ and $a = 20$ then

$m = 4(20) + 2(8)$

$m = 80 + 16$

$m = 96$

Finally 96 meatballs are required for the party

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.

Constantine picks two letters at random from the word constantinople with replacement. what is the probability that both letters

dedylja [7]

Constantinople has a total of 14 letters of which 9 are consonants

P(picking a consonant) = 9/14

P(2 letters are consonants with replacement) = 9/14 * 9/14 = 81/196

Does anybody know this?

alex41 [277]

Answer:

Step-by-step explanation:

So you want to add 7x degrees and (x-4) degrees. And it will be 8x - 4 = 180 degrees because it's 180 degrees in a straight line. And you want to + the 180 by 4 because there is -4 on the other side. so it will be 8x = 184 and you just divide 184 by 8 and it will be 23 easy. if you want to my help again you can text me on instargram jason_lee093
