Vesnalui [34]

1, 3, 5

The reasonable domain has a minimum value.

The reasonable range has a minimum value of 30,000.

The reasonable range has an implied, but unknown, maximum value.

Step-by-step explanation:

1. Years cannot be anything below 0.

2. The domain includes 0 because the answer can be the initial value.

3. 30,000 is the initial value and is the minimum solution.

4. The range has a minimal of 30,000.

5. Logically, we know city populations cant be numbers like a billion but we prove that mathematically.

notka56 [123]

Answer:

x= 30.29 (1-0.223) = 23.54

Ephraim paid a 22.3% tip, what was his bill before adding the tip?

23.54

Step-by-step explanation:

For this case we assume the following notation:

T= 30.29 represent the total paid for the dinner

x represent the amount before adding the tip

f =0.223 represent the fraction of the total amount destined to the tip

Based on this we can create the following relationship between T and x:

T = f*T + (1-f)T = f*T + x

And we can solve for x from the previous equation like this:

x = T - f*T

Taking T common factor we got:

x = T (1-f)

And if we replace we got:

x= 30.29 (1-0.223) = 23.54

And the amount destined to the tip would be fT = 0.223*30.29=6.75

And if we add the two values we see that:

23.54+6.75 = 30.29 representing the total cost.

So then the correct answer for the question:

Ephraim paid a 22.3% tip, what was his bill before adding the tip?

23.54

Tan(A+45°) - tan(A-45°) =2sec2A​
weeeeeb [17]

Answer:

\tan(A + 45 \degree)  -  \tan(A - 45 \degree)  \\   \\  = \frac{ \tan(A)  +  \tan(45 \degree) }{1 -  \tan(A)  \tan(45 \degree) }  -  \frac{ \tan(A)  -  \tan(45 \degree) }{1 +  \tan(A)  \tan(45 \degree) }  \\  \\

but tan 45° is 1;

=  \frac{ \tan(A) }{1 -  \tan(A) }  -  \frac{ \tan(A) }{1 +  \tan(A) }  \\  \\  \frac{\tan(A)  + { \tan }^{3}  A   + \tan(A)  -   { \tan}^{3}  A}{1 - { \tan }^{2} A }  \\  \\  =  (\frac{2  \tan(A) }{1 -  { \tan }^{2} A})  \\   \\  =  \frac{2 \sin(A) }{ \cos(A)  }  \times  { \sec }^{2} A \\  \\  =  \frac{2}{ \cos(2A) }  \\  \\  = 2 \sec(2A)
