The definition of a derivative is the slope of the tangent line.

Limit Definition of a Derivative: [tex]\displaystyle f'(x)= \lim_{h \to 0} \frac{f(x+h)-f(x)}{h}[/tex]  

Step-by-step explanation:

Step 1: Define

f(x) = 7x² + 7x + 3

Slope of tangent line at x = 4

Step 2: Differentiate

Substitute in function [Limit Definition of a Derivative]:                              [tex]\displaystyle f'(x)= \lim_{h \to 0} \frac{[7(x + h)^2 + 7(x + h) + 3]-(7x^2 + 7x + 3)}{h}[/tex][Limit - Fraction] Expand [FOIL]:                                                                    [tex]\displaystyle f'(x)= \lim_{h \to 0} \frac{[7(x^2 + 2xh + h^2) + 7(x + h) + 3]-(7x^2 + 7x + 3)}{h}[/tex][Limit - Fraction] Distribute:                                                                            [tex]\displaystyle f'(x)= \lim_{h \to 0} \frac{[7x^2 + 14xh + 7h^2 + 7x + 7h + 3] - 7x^2 - 7x - 3}{h}[/tex][Limit - Fraction] Combine like terms (x²):                                                     [tex]\displaystyle f'(x)= \lim_{h \to 0} \frac{14xh + 7h^2 + 7x + 7h + 3 - 7x - 3}{h}[/tex][Limit - Fraction] Combine like terms (x):                                                      [tex]\displaystyle f'(x)= \lim_{h \to 0} \frac{14xh + 7h^2 + 7h + 3 - 3}{h}[/tex][Limit - Fraction] Combine like terms:                                                           [tex]\displaystyle f'(x)= \lim_{h \to 0} \frac{14xh + 7h^2 + 7h}{h}[/tex][Limit - Fraction] Factor:                                                                                 [tex]\displaystyle f'(x)= \lim_{h \to 0} \frac{h(14x + 7h + 7)}{h}[/tex][Limit - Fraction] Simplify:                                                                               [tex]\displaystyle f'(x)= \lim_{h \to 0} 14x + 7h + 7[/tex][Limit] Evaluate:                                                                                                 [tex]\displaystyle f'(x) = 14x + 7[/tex]

Step 3: Find Slope

Substitute in x:                                                                                                [tex]\displaystyle f'(4) = 14(4) + 7[/tex]Multiply:                                                                                                           [tex]\displaystyle f'(4) = 56 + 7[/tex]Add:                                                                                                                  [tex]\displaystyle f'(4) = 63[/tex]

This means that the slope of the tangent line at x = 4 is equal to 63.

The aquarium opened at 8.00 am . In the first hour 140 people purchased admission tickets . In the second hour 25 % more people purchased admission tickets than the first hour . Each ticket cost 15.25 . What was the total amount of money paid for all the tickets purchased in the first two hours please help

Answers

Answer:

Total income= $4,083.75

Step-by-step explanation:

First, we need to calculate the total number of people that enter the aquarium in the first two hours.

1st hour= 140

2nd hour= 140*1.25= 175

Total number of people= 315

Now, we can determine the total amount of money earned:

Each ticket cost 15.25.

Total income= 315*15.25

Total income= $4,083.75

Un elev a depus la banca suma de 250 lei. Știind ca banca oferă dobânda anuala de 1%,iar stația impozitează dobânda cu 16%,aflati ce suma va avea elevul după un an de depunere.

Answers

Răspuns:

292,50

Explicație pas cu pas:

Dobânda totală% = (1% + 16%) = 17% = 17/100 = 0,17

Suma principală depusă, P = 250

Suma totală, A după 1 an poate fi calculată astfel:

A = P (1 + rt)

Unde ; r = rata dobânzii; t = timp

A = 250 (1 + (0,17 * 1))

A = 250 (1,17)

A = 292,5

Can you divide any number by zero? Passage: What Causes Earthquakes Natural earthquakes occur mostly from tectonic movements of the plates. Tectonic plates are large parts of the oceanic and continental lithosphere. The lithosphere is the solid outer section of Earth's crust. These sometimes shift into various positions both under water and above. Such movements generally occur along fault lines. When two rocks slide against each other, they create fault lines. These fault lines can be both extremely narrow or miles wide. Fault lines are created mostly in mountainous regions where plate tectonic movements are more likely. Movement between the tectonic plates is rarely smooth. When the plates slide against each other, they create a tremendous amount of friction. This friction forms seismic energy that travels in waves through the surface of the Earth. This causes the earthquake. While normal energy travels above the surface of the Earth, seismic energy travels under the Earth's surface. This creates more tension between the land plates, causes more shifting, and creates more fault lines. The spot below the Earth's surface where the rocks break against each other is called the focus of the earthquake. The place exactly above the focus on the surface of the planet is called the epicenter of the earthquake. Sometimes, earthquakes can also be man-made instead of natural. These can sometimes be caused due to explosions underground. Explosions big enough to cause a shift in the surface of the Earth are generally caused in mining tunnels or during nuclear testing. But the seismic energy formed due to these explosions is rarely very strong. Therefore, the strength of the earthquakes caused is not very high.Question: In What Causes Earthquakes," which detail supports the idea that friction exists between the plates underground? A. Fault lines are created mostly in mountainous regions where plate tectonic movements are more likely. B. Movement between the tectonic plates are rarely smooth. C. When two rocks slide against each other, they create fault lines. D. Explosions big enough to cause a shift in the surface of the Earth are generally caused in mining tunnels or during nuclear testing.
