To find the area of a sector, you can use the formula:

Area of Sector = (θ/360) * π * r^2

where θ is the central angle in degrees, r is the radius, and π is a mathematical constant approximately equal to 3.14159.

Let's calculate the areas for the given sectors:

r = 16 mi, θ = 150°

Area of Sector = (150/360) * π * (16 mi)^2

= (5/12) * π * 256 mi^2

≈ 334.930 mi^2

Therefore, the area of sector 16 is approximately 334.930 square miles.

The value of angle x is determined as 40 degrees.

The value of angle y is determined as 180 degrees.

The value of the missing angles is calculated by applying intersecting chord theorem which states that the angle at tangent is half of the arc angle of the two intersecting chords.

The value of angle x is calculated as follows;

50 = ¹/₂ (140 - x ) (exterior angle of intersecting secants)

2(50) = 140 - x

100 = 140 - x

x = 140 - 100

x = 40

The value of angle y is calculated as follows;

Answer:

2/13

Step-by-step explanation:

To find the probability of drawing a 6 or a king from a standard deck of cards, we need to determine the number of favorable outcomes (cards that are either a 6 or a king) and the total number of possible outcomes (total number of cards in the deck).

There are 4 kings in a standard deck (one king in each suit: hearts, diamonds, clubs, and spades) and 4 6s (one 6 in each suit).

Total number of favorable outcomes = 4 (4 kings) + 4 (4 6s) = 8

Total number of possible outcomes = 52 (total number of cards in the deck)

Therefore, the probability of drawing a 6 or a king is:

Probability = Number of favorable outcomes / Total number of possible outcomes

= 8 / 52

= 2 / 13

So, the probability of drawing a 6 or a king from a standard deck of cards is 2/13.

Answer:

0.5ml/hr

Step-by-step explanation:

Given:

Infusion rate: 0.002 units/min

To convert the infusion rate from units/min to ml/hr, we need to know the flow rate conversion factor specific to the medication and solution being administered.

In this case, we have the information that the patient is receiving 10 units of oxytocin (Pictocin) in 250 ml of D5W solution.

To calculate the ml/hr rate, we can use the following formula:

ml/hr = (Infusion rate in units/min * Volume in ml) / Time in min

ml/hr = (0.002 units/min * 250 ml) / 1 min

ml/hr = 0.5 ml/min

Therefore, the infusion rate of 0.002 units/min is equivalent to 0.5 ml/hr.

Answer:

$81.18

Step-by-step explanation:

Sale Price = Original Price - (Original Price * Discount Percentage)

Given:

Original Price = $82

Discount Percentage = 10%

Let's calculate the sale price:

Sale Price = $82 - ($82 * 10%)

Sale Price = $82 - ($82 * 0.1)

To simplify the calculation, we can convert 10% to its decimal form by dividing by 100:

Sale Price = $82 - ($82 * 0.1)

Sale Price = $82 - ($82 * 0.01)

Sale Price = $82 - $0.82

Using a calculator, we can find the value:

Sale Price = $81.18

Therefore, the sale price after a 10% discount would be $81.18.

The coordinates of point M are (1, 2).

The gradient of CB is 5.

The equation of line AD in the form y = mx + c is: y = (-1/5)x + 37/5.

To solve the given problem, we can follow these steps:

1. Calculate the coordinates of point M:

Since the diagonals of a rhombus bisect each other, the midpoint of the diagonal AC will give us the coordinates of point M.

Midpoint formula:

x-coordinate of M = (x-coordinate of A + x-coordinate of C) / 2

                 = (-3 + 5) / 2

                 = 2 / 2

                 = 1

y-coordinate of M = (y-coordinate of A + y-coordinate of C) / 2

                 = (8 - 4) / 2

                 = 4 / 2

                 = 2

Therefore, the coordinates of point M are (1, 2).

2. The gradient (slope) of a line passing through two points (x₁, y₁) and (x₂, y₂) can be found using the formula:

Gradient (m) = (-4 - 1) / (5 - 6)

            = -5 / -1

            = 5

Therefore, the gradient of CB is 5.

3. To find the equation of line AD, we need to calculate the gradient (m) of AD and the y-intercept (c).

Gradient of CB = 5

Gradient of AD = -1/5 (negative reciprocal of 5)

To find the y-intercept (c), we can substitute the coordinates of point A (-3, 8) into the equation y = mx + c and solve for c:

8 = (-1/5)(-3) + c

8 = 3/5 + c

c = 8 - 3/5

c = 40/5 - 3/5

c = 37/5

Therefore, the equation of line AD in the form y = mx + c is:

y = (-1/5)x + 37/5.

Answer:

Q1: $1,360, Q2: $30.83, Q3: $325.50, Q4: $75

Step-by-step explanation:

QUESTION 1:

If the minimum payment is made and no additional charges are made, the balance next month should be $1,400 minus 3% of $1,400, which is $1,360.

QUESTION 2:

To calculate the interest charged for the month, we need to determine the average daily balance. Assuming no other transactions, the average daily balance would be (($2,500 * 20) + ($1,100 * 10)) / 31 = $2,032.26. Multiply this by the APR of 18% and divide by 365 to get the daily interest rate. The interest charged for the month would be approximately ($2,032.26 * 0.18) / 365 * 31 = $30.83.

QUESTION 3:

After making the first minimum pyment, the new balance would be $350 minus 7% of $350, which is $325.50.

To calculate the minimum payment due the next month, we take 7% of the new balance, which is 7% of $325.50, equal to $22.79 (rounded to the nearest cent).

QUESTION 4:

The minimum payment required on a balance of $2,500 would be 3% of $2,500, which is $75.

Answer:

  tan(2x) = 2√2

Step-by-step explanation:

You want tan(2x) when tan(x) is -2/√2 and x is a 4th-quadrant angle.

The tangent double-angle identity is ...

  tan(2x) = 2tan(x)/(1 -tan(x)²)

For tan(x) = -2/√2, this gives ...

  tan(2x) = 2(-2/√2)/(1 -(-2/√2)²) = -2√2/(1 -2)

  tan(2x) = 2√2

Answer:

The area bounded by the two functions f(x) and g(x) on the interval [0, 2π] is 6π.

Step-by-step explanation:

The range of y = sin(2x) is [-1, 1].

As function f(x) = sin(2x) + 1 has been translated 1 unit up, the range of f(x) is [0, 2].

The range of y = cos(x) is [-1, 1].

As function g(x) = cos(x) - 2 has been translated 2 units down, the range of g(x) is [-3, -1].

As ranges of the functions do not overlap, the two functions do not intersect.

As the curve of f(x) is above the x-axis, and the curve of g(x) is below the x-axis, we can integrate to find the area between the curve and the x-axis for each function in the given interval, then add them together.

Note: As g(x) is below the x-axis, the evaluation of the integral will return a negative area. Therefore, we need to negate the integral so we have a positive area (since area cannot be negative).

[tex]\begin{aligned}A_1=\displaystyle \int^{2\pi}_{0} (\sin(2x)+1)\; \text{d}x&=\left[-\dfrac{1}{2}\cos(2x)+x \right]^{2\pi}_{0}\\\\&=\left(-\dfrac{1}{2}\cos(2(2\pi))+2\pi\right)-\left(-\dfrac{1}{2}\cos(2(0))+0\right)\\\\&=\left(-\dfrac{1}{2}+2\pi\right)-\left(-\dfrac{1}{2}\right)\\\\&=2\pi\end{aligned}[/tex]

As the curve is below the x-axis, remember that we need to negate the integral to find the area.

[tex]\begin{aligned}A_2=-\displaystyle \int^{2\pi}_{0} (\cos(x)-2)\; \text{d}x&=-\left[\vphantom{\dfrac12}\sin(x)-2x \right]^{2\pi}_{0}\\\\&=-\left[(\sin(2\pi)-2(2\pi))-(\sin(0)-2(0))\right]\\\\&=-\left[(0-4\pi)-(0-0)\right]\\\\&=-\left[-4\pi\right]\\\\&=4\pi\end{aligned}[/tex]

[tex]\begin{aligned}A_1+A_2&=2\pi+4\pi\\&=6\pi\end{aligned}[/tex]

Therefore, the area bounded by the two functions f(x) and g(x) on the interval [0, 2π] is 6π.

The height of the cylinder is 25.

Option C is the correct answer.

We have,

To find the height of the right cylinder, we need to use the given information of the diagonal length and the total surface area.

The diagonal length of a right cylinder can be found using the formula:

diagonal = √(height² + radius²)

Given that the diagonal length is 37, we can set up the equation:

37 = √(height² + radius²)

We also know that the total surface area of a right cylinder is given by:

surface area = 2πrh + 2πr²

Given that the total surface area is 492π, we can set up the equation:

492π = 2πrh + 2πr²

Simplifying the surface area equation, we have:

246 = rh + r²

Now we have a system of equations:

37 = √(height² + radius²)

246 = rh + r²

Since we only need to find the height of the cylinder, we can focus on the first equation:

37 = √(height² + radius²)

Squaring both sides of the equation, we get:

37² = height² + radius²

1369 = height² + radius²

Substituting the second equation (246 = rh + r²) into the equation above, we have:

1369 = height² + (246 - rh)

Simplifying further, we get:

1369 = height² + 246 - rh

Now, let's analyze the answer options:

a. 35

b. 42

c. 25

d. 17

e. 32

We need to substitute each value into the equation and check if it satisfies the equation.

After checking each option, we find that the height that satisfies the equation is:

c. 25

Answer:

The length of a side of the base of the box is 13 cm.

Step-by-step explanation:

To find the length of a side of the base of the box, we need to use the formula for the volume of a box.

The volume of a box is given by the formula:

V = l^2 * h

Where:

V is the volume,

l is the length of a side of the base, and

h is the height of the box.

Substituting the given values:

V = 1352 cm^3

h = 8 cm

1352 = l^2 * 8

Dividing both sides by 8:

l^2 = 169

Taking the square root of both sides:

l = √169

Calculating the length of a side of the base:

l = 13 cm

Therefore, the length of a side of the base of the box is 13 cm.

To find the length of the third side of a right triangle when two sides are given, we can use the Pythagorean theorem. The theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

Let's assume the two given sides are 'a' and 'b', and the unknown third side is 'c' (the hypotenuse).

Using the Pythagorean theorem:

c² = a² + b²

Substituting the given values:

c² = 4² + 5²

c² = 16 + 25

c² = 41

To find the length of 'c', we need to take the square root of both sides:

c = √41

So, the length of the third side is √41 (approximately 6.40) when rounded to two decimal places.

Therefore, the possible length of the third side of the right triangle is √41.

Step-by-step explanation:

We will use a phayragoras theorem

a^2 +b^2= c^2

let side1=4 be a

let side2=5 be b

let the 3rd side be the hypotnuous=c

therfore 4^2+5^2=c^2

=16+25=c^2
