A derivative is a financial instrument that derives its value from an underlying asset. It is a contract between two or more parties that specifies conditions (such as the date, price, and quantity of the underlying asset) under which payments, or payoffs, are to be made between the parties. Derivatives can be used for a variety of purposes, such as hedging risk or speculating on the future price of an asset.

A function is a mathematical relation between two sets of numbers that assigns each element in one set to exactly one element in the other set. For example, the function f(x) = 2x+3 assigns each real number x to the real number 2x+3

Answer:

a. Let Q be the total number of quarters you take with you when you go shopping. The total number of quarters you have is 20, and you find 40% more quarters in your room, which is an additional 0.4 * 20 = <<0.420=8>>8 quarters. Therefore, the total number of quarters you have after finding more quarters in your room is 20 + 8 = <<20+8=28>>28 quarters. When you go shopping, you spend 50% of the total number of quarters, which is 0.5 * 28 = <<0.528=14>>14 quarters. Therefore, the total number of quarters you take with you when you go shopping is 28 - 14 = <<28-14=14>>14 quarters. This can be represented by the expression Q = 28 - 0.5 * 28.

b. If you have 14 quarters with you when you go shopping, and you spend 50% of the total number of quarters, then you have 0.5 * 14 = <<0.514=7>>7 quarters left. Since each quarter is worth $0.25, you have 7 * 0.25 = $<<70.25=1.75>>1.75 left. Answer: \boxed{1.75}.

Answer: 8 Nights

Step-by-step explanation:

Cost of a plane ticket to Florida(c) = $1000

cost at the hotel per night (n)

Amount left with Karla after spending on the flight ticket =

$3000-$1000= $2000

To find out how many nights she can stay we should divide the remaining amount she has with (n) = $2000/$250 = 8

Hence Karla can stay for 8 nights

What is exponential growth?

An exponential function's curve is created by a pattern of data called exponential growth, which exhibits higher increases with time.

Consider a population of mice that increases exponentially every year by a factor of two, starting with 2 in the first year and increasing to 4 in the second, 8 in the third, 16 in the fourth, and so on. The population is rising by a factor of 2 per year in this example. If mice gave birth to four pups instead, you would then have 4, 16, 64, and 256.

Linear growth, which is additive, and geometric growth can be contrasted with exponential growth, which is multiplicative (which is raised to a power).

This equation represents exponential growth because the base is greater than 1, the function represents growth and  Whenever the base is less than 1, the function represents decay.

The base 1.06 is greater than 1, hence The equation represents exponential growth.

The formula for exponential growth:

[tex]y=a(1+r)^{x}[/tex]

where,

f(x) = exponential growth function

a = initial amount

r = growth rate

x = number of time intervals

In this case, [tex]r=1.06+1 = 2.06[/tex]

Given:

The graph of the line is given.

From graph we have to find the equation of line.

Let the graph passes through the points (0, 6) and (2, 10).

The value of the equation h(x) = -5x-4 is - 19 when h = (3).

An equation is a mathematical statement that contains the symbol "equal to" between two expressions with identical values.

As in 3x + 5 = 15, for example.

There are many different types of equations, including linear, quadratic, cubic, and others.

The three primary forms of linear equations are point-slope, standard, and slope-intercept.

So, the equation we have is:

h(x) = -5x-4

Now, solve the equation when h = (3)

h(x) = -5x-4

h(3) = -5(3) -4

h(3) = -15 - 4

h(3) = - 19

In order for m n to be even, m must be even or n must be an even number.

Let's understood what is integers.

In mathematics, a collection of both positive and negative integers is referred to as an integer. Like whole numbers, integers do not contain a fractional portion. The definition of an integer is that a number that can be either positive, negative, or zero but is not a fraction. On integers, we can carry out all arithmetic operations, including addition, subtraction, multiplication, and division. Examples of integers include 1, 2, 5, 8, -9, and -12. "Z" stands for an integer.

Proof by contraposition:

Suppose that the statement m“ is even or is even n” is not true. Consequently, m and n should both be odd. Let's check to determine if the sum of two odd numbers is even or odd: Let m and n be equal to 2a+1 and 2b+1 respectively, then their product is:

(2a+1) (2b+1) = 4ab+2a+2b+1 =2(2ab+a+b) +1

This shows that the expression 2(2ab+a+b) +1 is of the form 2n+1, thus the product is odd. If the product of odd numbers is odd, then m n is not true to be even. Therefore, in order for m n to be even, m must be even, or n must be an even number.

Answer:196

Step-by-step explanation:

Verified that during the first 3 seconds of fall the instantaneous velocity equals the average velocity, the time is 1.5 seconds

The height of an object t seconds after it is dropped from a height of 300 meters is

s(t) = -4.9t^2 + 300

The average velocity of object during first 3 seconds

= s(3) - s(0) / 3 - 0

s(3) = -4.9 × (3)^2 + 300

= -44.1 + 300

= 255.9 meters

s(0) = -4.9(0)^2 + 300

s(0) = 300

The average velocity = (255.9 - 300) / 3 - 0

= -44.1 / 3

= -14.7 meter per second

To find  instantaneous velocity differentiate the function

= -9.8t

The instantaneous velocity = The average velocity

-9.8t = -14.7

t = -14.7/-9.8

t = 1.5 seconds

Therefore, time is 1.5 seconds

The measures of the lengths of the sides and angles of the triangles found using the law of cosines and the law of sines are presented as follows;

Question 1

∠A = 47.35°

∠B = 78.65°

c = 3.3

Question  2

∠B = 78.24°

∠C = 29.76°

a = 67.03

Question 3

∠A = 45.77°

∠B = 86.417°

∠C = 47.813°

Question 4

∠A = 36.15°

∠B = 60.48°

∠C = 93.37°

Question 5

a = 258.98

b = 327.41

∠C = 53°

Question 6

a = 34.11

b = 73.987

∠C = 53°

The law of cosines is a relationship between two sides (b and c) and the included angle, (∠A) and the third side (a) of the triangle.

Mathematically; a² = b² + c² - 2·b·c·cos(A)

Question 1

The dimensions of the triangle ΔABC are;

a = 3.0, b = 4.0, ∠C = 54°

The law of cosines indicates that we get;

c² = b² + a² - 2·b·a·cos(∠C)

Therefore;

c² = 3.0² + 4.0² - 2 × 3.0 × 4.0 × cos(54°) ≈ 10.893

The law of sines indicates that we get;

sin(54°)/3.3 = sin(∠A)/3.0

Question 2

b = 69, c = 35, ∠A = 72°

a² = 69² + 35² - 2 × 69 × 35 × cos(72°) ≈ 4493.45

The law of sines indicates that we get;

sin(72°)/67.03 = sin(∠B)/69

∠B = arcsine(69 × sin(72°)/67.03) ≈ 78·24°

∠C = 180° - 72° - 78.24° ≈ 29.76°

Question 3

a = 28, b = 39, c = 29

a² = b² + c² - 2·b·c·cos(A)

cos(A) = (a² - (b² + c²)) ÷ (2·b·c)

Therefore; cos(A) = (28² - (39² + 29²)) ÷ (-2 × 39 × 29) ≈ 0.6976

sin(45.77)/28 = sin(B)/39

sin(B) = 39 × sin(45.77)/28 ≈ 0.998

Question 4

a = 13, b = 17, c = 22

cos(A) = (13² - (17² + 22²)) ÷ (-2 × 17 × 22) ≈ 0.807

sin(36.15)°/13 = sin(∠B)/17

sin(∠B) = 17 × sin(36.15)°/13

Question 5

The parameters of the triangle are; ∠A = 50°, ∠B = 77°, c = 270

Please find attached the sketch of the triangle in the correct option created with MS Word

a/sin(50°) = 270/sin(53°)

a = sin(50°) × 270/sin(53°) ≈ 258.98

b = sin(77°) × 270/sin(53°) ≈ 329.41

Question 6

The parameters of the triangle are;

∠A = 27°, ∠B = 100°, c = 60

Please find attached the drawing of the correct triangle

∠C = 180° - 27° - 100° = 53°

∠C = 53°

60/sin(53°) = a/sin(27°)

a = sin(27°) × 60/sin(53°) ≈ 34.11

b = sin(100°) × 60/sin(53°) ≈ 73.987
