The amplitude and period of each function are calculated and listed below

The amplitude and period of each function can be determined using their standard form:

y = A sin (Bx + C) or y = A cos (Bx + C)

where |A| is the amplitude, B is the frequency (or angular frequency), and 2π/B is the period.

Let's apply this formula to each function:

y = cos(2x)

Amplitude = 1

Period = 2π/2 = π

y = -sin(2x)

Amplitude = 1

Period = 2π/2 = π

y = -3sin(3x)

Amplitude = 3

Period = 2π/3

y = (1/2)cos(4x)

Amplitude = 1/2

Period = 2π/4 = π/2

y = 10sin(1/2x)

Amplitude = 10

Period = 2π/(1/2) = 4π

y = 5cos(1/4x)

Amplitude = 5

Period = 2π/(1/4) = 8π

y = (-1/3)cos(1/3x)

Amplitude = 1/3

Period = 2π/(1/3) = 6π

y = 4sin(-2x)

Amplitude = 4

Period = 2π/(-2) = -π

y = -2sin(2πx)

Amplitude = 2

Period = 2π/(1) = 2π

y = -3sin(πx)

Amplitude = 3

Period = 2π/π = 2

y = 1 + (1/2)cos(πx)

Amplitude = 1/2

Period = 2π/π = 2

y = -2 + cos(4πx)

The requried, quadratic equation that models the path of the golf ball, is 16.0850t² - 110.560t - 190 = 0 and the angle the ball takes off is 64.4⁰.

The motion of the golf ball can be modeled using two equations, one for the vertical motion and another for the horizontal motion.

The equation for the vertical motion of the ball is given by:

h = V₀t - ¹/₂gt²,

Using the given values, we find that,
V₀ = √(2 x 32.17 x 190) = 110.56 ft/s.

Substituting this value and the value of g into the equation of motion for the vertical direction, we get -190 = 110.56t - ¹/₂(32.17)t², which simplifies to 16.0850t² - 110.560t - 190 = 0.

The equation for the horizontal motion of the ball is given by [tex]x = V_xt[/tex], where x is the horizontal distance traveled, Vx is the initial horizontal velocity, and t is the time. Using the given value of x, we can find Vx as [tex]V_x = 440/t.[/tex]

We can then solve the quadratic equation 16.0850t² - 110.560t - 190 = 0 to find the time t of flight.
Using the formula method, we get t = 8.3 s. Substituting this value into the equation for the horizontal motion, we get [tex]V_x = 440/8.3 = 53.01 ft/s.[/tex]

Finally, we can find the angle of projection θ using the formula tan θ = [tex](V_y) / (V_x)[/tex],

tan θ = (110.56)/(53.01),

which simplifies to tan θ = 2.086. Taking the inverse tangent of both sides, we get θ = tan⁻¹(2.086) = 64.4⁰.

Therefore, the angle at which the ball takes off is 64.4⁰.

2. The solution to the integral is: -2cot(x) - 4ln|sin(x)| - 3x + C

6. The integral converges and its value is 0.

2. To solve this integral using partial fractions, we need to rewrite the integrand as a sum of simpler fractions. We first rewrite the integrand as follows:

(2cos(x)/sin²(x) - 4 sin(x) - 5) = 2/sin(x)² - 4sin(x) - 5

Now we need to express the first term 2/sin(x)² as a sum of two fractions with different denominators. To do this, we let:

2/sin(x)² = A/sin(x) + B/sin(x)²

Multiplying both sides by sin(x)², we have:

2 = A sin(x) + B

Next, we need to determine the values of A and B. To do this, we can substitute two different values for x that make sin(x) ≠ 0, such as x = 0 and x = π/2.

Substituting x = 0, we get:

2 = A(0) + B

2 = B

Substituting x = π/2, we get:

2 = A(1) + B

2 = A + B

2 = A + 2

Therefore, A = 0.

So we have:

2/sin(x)² = B/sin(x)²

B = 2

Substituting these values back into our original expression, we get:

(2cos(x)/sin²(x) - 4 sin(x) - 5) = 2/sin(x)² - 4sin(x) - 5

= 2/sin(x)² - 4sin(x)/sin(x) + 2sin(x)/sin(x) - 5

= 2/sin(x)² - 4cot(x) + 2 - 5

= 2/sin(x)² - 4cot(x) - 3

Now we can integrate each term separately:

∫2/sin(x)² dx = -2cot(x) + C1

∫-4cot(x) dx = -4ln|sin(x)| + C2

∫-3 dx = -3x + C3

So the solution to the integral is:

∫(2cos(x)/sin²(x) - 4 sin(x) - 5) dx = -2cot(x) - 4ln|sin(x)| - 3x + C

where C = C1 + C2 + C3 is the constant of integration.

6. We can solve this integral by using the substitution u = x - 2, which gives us du = dx. We can then rewrite the integral as:

∞

∫₁ (1/(x-2)²) dx = ∞

∫-∞ (1/u²) du

Now, we can evaluate this integral as:

∞

∫-∞ (1/u²) du = [-1/u]∞

= [0 - (-1/(-∞))]

= 0 - 0

= 0

Answer:

(a) The total ratio is 1 + 3 = 4, so Jill's share is (3/4) of £60:

Jill's share = (3/4) × £60 = £45.

(b) The ratio of their ages remains the same, so if Jack is one year older, Jill is also one year older. Therefore, Jill's age is 4 and Jack's age is 2, and Jack's share is (2/4) of £60:

Jack's share = (1/2) × £60 = £30.

(c) Let x be the age of Jack when he receives £25 from Uncle Fred. According to the problem, Jill is always two years older than Jack. Therefore, when Jack is x years old, Jill is x + 2 years old. The ratio of their ages is x : (x + 2), and this ratio is equal to 5/7 (25 pounds is 5/7 of 35 pounds, which is the total amount that they will receive). We can write an equation to solve for x:

x/(x+2) = 5/7

7x = 5(x + 2)

7x = 5x + 10

2x = 10

x = 5

Therefore, Jack will be 5 years old when he receives £25 from Uncle Fred at Christmas.

A) £45 because Jill will get 3/4 and Jack will get 1/4. To check our work, 60 divided by 4 is 15. 15 times 3 is 45 and 15 times one is 15.

B) £30 because it is a new year, both nephews will increase by one year. Now Jill is 4 and Jack is 2. So each kid will get half the share. 2 divided by 4 is 0.5 which is half of one. Half of 60 is 30.

C) 5 years Jill will always be 2 years older than Jack; this shows us that if some more years pass, Jill will be 7 and Jack will be 5 —> 1/4 x £60 = £25 Multiplying both sides by 4/60, we get:x = 5/4. This means Jack will be 5.

Area = length x width

Area = (1 + 2x)(2 - 3x)

Therefore, the area of the patio is (1 + 2x)(2 - 3x) square yards.

The perimeter of a rectangle is given by the sum of the lengths of all four sides.

So, the perimeter of the patio is:

Perimeter = 2(length + width)

We need to first determine how many totally odd counting numbers there are between 1 and 9. The answer is 250.

It is an integer that is not divisible by two and therefore has a remainder of 1 when divided by two. It is also referred to as an odd number, an odd integer, or an uneven number.

For this, let us consider all the digits from 1 to 9, and their respective sums.

Digit: 1 Sum: 1 (odd)

Digit: 3 Sum: 3 (odd)

Digit: 5 Sum: 5 (odd)

Digit: 7 Sum: 7 (odd)

Digit: 9 Sum: 9 (odd)

Since all the digits between 1 and 9 and their respective sums are all odd, it means that any counting number less than 10 that is composed of only these digits would be totally odd. This means that there are 5 totally odd counting numbers less than 10, i.e., 1, 3, 5, 7 and 9.

Now, since any counting number less than 1000 can be composed of any combination of these 5 digits, the total number of totally odd counting numbers less than 1000 can be calculated by multiplying the number of digits (5) by the number of combinations of those digits (999).

For the given right angled triangle cosine of angle B is 5√89/89.(option A).

What is right angled triangle?

It is a particular type of triangle having one angle is 90° or right angle. The adjacent sides of the right angle are called base and the perpendicular and the opposite side of 90° is called hypotenuse.

The given triangle is the right angled triangle. The three sides of a right angled triangle are called base, perpendicular and hypotenuse.

In the given figure base=  5 inches and perpendicular = 8 inches

By Pythagoras theorem at first we will find out the hypotenuse. Let the hypotenuse= c inches

For any right angled triangle,

(perpendicular)² +(base)²= (hypotenuse)²

⇒ (8)² + (5)² = (c)²

⇒ 64+ 25 = c²

⇒ c² =89

⇒ c= ±√89

As hypotenuse cannot be negative

So hypotenuse = √89 inches.

Now to find cosine of angle B that is cos B we will use the trigonometric function.

cos B= Adjacent side/ hypotenuse

         = 5/√89

The second quadrant is characterized by negative x-coordinates and positive y-coordinates, while the fourth quadrant has positive x-coordinates and negative y-coordinates.

If the preimage of the quadrilateral is in the second quadrant, then its x-coordinates are negative and its y-coordinates are positive.
