The exact value of cos( α+ β) is (-24/85)(√7 + 2).

Describe Trigonometric Identity?

Trigonometric identities are equations involving trigonometric functions that are true for all values of the variables involved. These identities are used to simplify expressions involving trigonometric functions, to solve trigonometric equations, and to prove other mathematical results.

Some of the most common trigonometric identities include the Pythagorean identity, which relates the sine and cosine functions to the unit circle and the tangent function; the sum and difference formulas, which relate the trigonometric functions of the sum or difference of two angles to the trigonometric functions of the individual angles; and the double angle and half angle formulas, which relate the trigonometric functions of twice or half an angle to the trigonometric functions of the original angle.

We can use the trigonometric identity cos(α + β) = cos(α)cos(β) - sin(α)sin(β) to find the value of cos(α + β), given the values of sin(α), sin(β), and the quadrants in which α and β lie.

We are given that sin(α) = 15/17 and that a lies in quadrant I, so we can use the Pythagorean identity to find cos(α):

cos(α) = √(1 - sin²(α)) = √(1 - (15/17)²) = √(112/289) = (4/17)√7

We are also given that sin(β) = 4/5 and that ẞ lies in quadrant II. Since sin(ẞ) is positive and cos(β) is negative in quadrant II, we can use the Pythagorean identity to find cos(β):

cos(β) = -√(1 - sin²(β)) = -√(1 - (4/5)²) = -3/5

Now we can substitute these values into the formula for cos(α + β):

cos(α + β) = cos(α)cos(β) - sin(α)sin(β)

= (4/17)√7 * (-3/5) - (15/17) * (4/5)

= (-12/85)√7 - (12/17)

= (-24/85)(√7 + 2)

Therefore, the exact value of cos( α+ β) is (-24/85)(√7 + 2).

An equation for the function graphed above include the following: g(x) = -1/4|x + 1| - 2.

How to interpret and determine the equation of g(x)?

By critically observing the graph of this absolute value function, we can reasonably infer and logically deduce that the parent absolute value function f(x) = |x| was vertically compressed by a factor of 1/4, reflected over the x-axis, followed by a vertical translation 2 units down, and then a horizontal translation to the left by 1 unit, in order to produce the transformed absolute value function as follows;

f(x) = |x|

y = A|x + B| + C

g(x) = -1/4|x + 1| - 2

In conclusion, the value of the variables A, B, and C are -1/4, 1, and 2 respectively.

Yes, children, students, and senior citizens being eligible for discounted movie tickets is an example of price discrimination.

What is price discrimination?

When a merchant charges different rates to various groups of clients based on their willingness to pay, this is referred to as price discrimination.

Price discrimination requires market strength, definable client segmentation, and the capacity to avoid arbitrage among various groups.

Price discrimination is a sales approach in which the seller charges varying rates for the same product or service based on what the vendor believes the consumer would agree to.

the sum of two numbers is 57. The larger number is 15 more than the smaller number. What are the numbers?​

Answers

Answer:

21 and 36

Step-by-step explanation:

So we would start by setting up an equation like x + x = 57 only we know that the larger number is 15 more than the smaller number so we would change it to x + x+15 = 57 so 2x + 15 = 57. Now simply solve and 2x = 42. Divide and x is equal to 21 so the smaller number is 21. The larger number is 15 more than the small so 15 + 21 is equal to 36. The two numbers would be 21 and 36.

Answers

Answer:

Below in bold.

Step-by-step explanation:

Using the product rule:

dy/dx = (1 - x)* d (x² - 4)²​/dx  + (x² - 4)² * -1

Differentiate (x² - 4)²​:-

Using the Chain Rule:

this =  2(x² - 4) * 2x

      = 4x(x² - 4)

So substituting the above we have

dy/dx  =  (1 - x)4x(x² - 4) + (x² - 4)² * -1

          =    (1 - x)4x(x² - 4) - (x² - 4)²

          =     (x² - 4)(4x(1 - x) - (x² - 4))

          =    (x² - 4)(4x - 4x² - x² + 4)

b. £1 = 100p, so the cost \(C'\) (in £) is 1/100 of the cost found in part (a),

\(C' = \dfrac{50d + 40e}{100} = \boxed{\dfrac d2 + \dfrac{2e}5}\)
