Answer:
(0, π/4] ∪ (π, 5π/4]
Step-by-step explanation:
Multiplying by 2 gives ...
cot(x) ≥ 1
The cotangent function decreases from ∞ to 1 in the domain (0, π/4], and again in the domain (π, 5π/4]. The solution is the union of these two intervals.
x ∈ (0, π/4] ∪ (π, 5π/4]

Is B 30 right?
Answers
b is the correct answer u got it
Answer:
C. 30
Step-by-step explanation:
2x = 60
x = 30
Also because the right angle of a triangle which is the angle where (2x) is at is equal to 90 degrees always, so since one of the angles is 60 the other will be 30 because the three angles of a triangle add up to 180 degrees:
90 + 60 = 150
180 - 150 = 30

Step-by-step explanation:
A composite figure is made up of simple geometric shapes. To find the area of a composite figure or another irregular-shaped figure, divide it into simple, nonoverlapping figures. Find the area of each simpler figure, and then add the areas together to find the total area of the composite figure.
Finding the Area of Composite Shapes
In order to find the composite area of two or more shapes, simply find the area of each shape and add them together. Therefore, the answer is 96 feet²

The price of an item has been reduced by 80%. The original price was $40. What is the price of the item now?
Answers
The price of the item now is $8 after an 80% reduction. To find the price of the item after the 80% reduction, you can follow these steps:
1. Calculate the amount of the reduction: 80% of $40.
2. Subtract the reduction amount from the original price to get the final price.
Step 1: Calculate the amount of the reduction:
80% of $40 = 0.80 * $40 = $32
Step 2: Subtract the reduction amount from the original price:
Original Price - Reduction Amount = $40 - $32 = $8
So, the price of the item now is $8 after an 80% reduction.

Sally rents a life jacket for a one-time fee of $5. She then rents a canoe for $15 per hour. Which expression represents the
total cost, in dollars, to rent the life jacket and the canoe for h hours?
A 5+15h
B 10
15 + 5
20h
Answers
Explanation: You add the money then multiply it by the hours. B wouldn't make any sense, A would only be multiplying th hours by $15 but the life jacket needs to as well, and 15+5 isn't multiplying the hours so the only logical answer would be 20h.

What is the perimeter of the figure?"
Answers
9514 1404 393
Answer:
46 yd
Step-by-step explanation:
The sum of horizontal lengths across the top is 8+6 = 14 yd. The length across the bottom is the same, so the total of horizontal lengths is
14 yd +14 yd = 28 yd
The sum of vertical lengths at the right is the same as the sum of vertical lengths at the left, 9 yd, so the total of vertical lengths is ...
9 yd + 9 yd = 18 yd
The total of all lengths around the perimeter of the figure is ...
28 yd + 18 yd = 46 yd

Answers
9514 1404 393
Answer:
minimum: -∛4 ≈ -1.58740maximum: ∛12 ≈ 2.28943Step-by-step explanation:
The expression under the radical can be written in vertex form as ...
x^2 -12x +32 = (x -6)^2 -4
The function will be symmetrical about x=6. The minimum is at x=6 where we have ...
F(6) = ∛(-4)
The maximum is at the end of the interval farthest from the vertex, so is ...
F(10) = ∛((10 -6)² -4) = ∛12
The minimum is -∛4 ≈ -1.587; the maximum is ∛12 ≈ 2.289.
