Answer 1

Answer:

The temperature changed by 27F from midnight to noon.

Step-by-step explanation:

We can find the change in degrees by finding the difference of the two temperatures:

10 - (-17) = change in degrees

We can say the difference is equivalent to 10 + 17, since there are two negative signs (the subtraction sign and the negative sign)

So 10 + 17 = 27F difference.

What is trigonometry?

The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry. The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.

Given that in ΔPQR, p = 8.5 cm, q = 1.7 cm and r=7.7 cm. The value of angle ∠r will be calculated as,

r² = p² + q² -2pqcos(r)

(7.7)² = (8.5)² + (1.7)² - 2 x 8.5 x 1.7cos(r)

59.29 -75.14 = -28.9cos(r)

cos(r) = 15.85 / 28.9

cos(r) = 0.55

r = cos⁻¹(0.55)

r = 56.63°

Step-by-step explanation:

Hi! I'm lazy but I'll explain number two so you get the concept. 2x + y =10

Well, It says x = 5. When a number is next to another number like this: 5(6), it means multiplication. Same when a number and a letter are together like this: 2x. So that means it's 2 times 5, since 5 = x. 2 times 5 is 10. So what plus 10 equals 10 (10 + y = 10) The answer now is obviously 0. So that's how you do those equations! Hope u understand lol :>

then solve and you get x^2 = 64 which means x=8

then since CE and ED are the same and congruent lines ED will also be 8 so you add the 8 up and get 16.

Given f(x) = ax + b/x,
f(1) = 1, and f(2)= 5, find constants a and b

Answers

Answer:

a = 3, b = - 2

Step-by-step explanation:

Given f(1) = 1 and f(2) = 5, that is

substitute x = 1 and equate to 1, substitute x = 2 and equate to 5

a + b = 1 → (1)

2a + [tex]\frac{b}{2}[/tex] = 5 → (2)

Multiplying (1) by - 2 and adding to (2) will eliminate a

- 2a - 2b = - 2 → (3)

Add (2) and (3) term by term to eliminate a

0 - [tex]\frac{3}{2}[/tex] b = 3

- [tex]\frac{3}{2}[/tex] b = 3 ( multiply both sides by - [tex]\frac{2}{3}[/tex] )

b = - 2

Substitute b = - 2 into (1)

a - 2 = 1 ( add 2 to both sides )

a = 3

Then a = 3 and b = - 2

A company makes paper labels for paint cans. As shown below, each can is in the shape of a cylinder with a height of 9in and a diameter of 8in. The paper label is wrapped around the can and covers only the side of the can (not the top or bottom). If the company makes 15 labels, how many square inches of paper will be needed? Use 3.14 for π, and do not round your answer.

Answers

Answer:

423

Step-by-step explanation:

Firstly we need to find the circumference of the circle.

Circumference = 2 × Radius with Pi

=2×8×3.14= 50.24

Now we must find the area of 1 label.

Area of 1 label= 3.14 × 9= 28.26cm²

Multiplying by the number of labels =

28.26 × 15

= 423.9 cm²

So, we'll just keep the answer 423 because we were asked how many square inches of paper will be needed.

Know what atomic mass and atomic number represent Memories of a MemoryHave you ever witnessed something amazing, shocking or surprising and found when describing the event that your story seems to change the more you tell it? Have you ever experienced a time when you couldn't really describe something you saw in a way that others could understand? If so, you may understand why some experts think eyewitness testimony is unreliable as evidence in scientific inquiries and trials. New insights into human memory suggest human memories are really a mixture of many non-factual things.First, memory is vague. Imagine your room at home or a classroom you see every day. Most likely, you could describe the room very generally. You could name the color of the walls, the floors, the decorations. But the image you describe will never be as specific or detailed as if you were looking at the actual room. Memory tends to save a blurry image of what we have seen rather than specific details. So when a witness tries to identify someone, her brain may recall that the person was tall, but not be able to say how tall when faced with several tall people. There are lots of different kinds of "tall."Second, memory uses general knowledge to fill in gaps. Our brains reconstruct events and scenes when we remember something. To do this, our brains use other memories and other stories when there are gaps. For example, one day at a library you go to quite frequently, you witness an argument between a library patron and one of the librarians. Later, when telling a friend about the event, your brain may remember a familiar librarian behind the desk rather than the actual participant simply because it is recreating a familiar scene. In effect, your brain is combining memories to help you tell the story.Third, your memory changes over time. It also changes the more you retell the story. Documented cases have shown eyewitnesses adding detail to testimony that could not have been known at the time of the event. Research has also shown that the more a witness's account is told, the less accurate it is. You may have noticed this yourself. The next time you are retelling a story, notice what you add, or what your brain wants to add, to the account. You may also notice that you drop certain details from previous tellings of the story.With individual memories all jumbled up with each other, it is hard to believe we ever know anything to be true. Did you really break your mother's favorite vase when you were three? Was that really your father throwing rocks into the river with you when you were seven? The human brain may be quite remarkable indeed.

How long is it? What puts it on? how many inches are in a feet Introduction: In the greater Seattle-Tacoma area, an arms race continues between hospitals to gather the most modern technology available to use on their patients - currently this arms race's primary device of choice-robotic surgical systems. Why robotic surgical systems? These systems in theory allow surgeons to be more precise in performing complex surgical procedures on patients. With greater precision comes a greater chance of successfully healing the patient as well as reducing the patient's possibility for complications and recovery time. In addition to these benefits, hospitals through the use of superior technology can serve more patients and potentially reap greater benefits from insurance companies and patients for these advanced medical services The price of this superior care though comes at a cost to the patient increased charges) as well as purchase costs to the hospital. One of the most popular robotic systems is called da Vinci and is manufactured and sold by Intuitive Surgical (http://www.intuitivesurgical.com/). The da Vinci was FDA approved in July 2000 and can currently perform urologic, gynecologic, colorectal, head and neck, cardiothoracic, and other general surgery procedures. As important as the device is the surgeon that is trained in the use of the system. The more repetitions on the robotic system, the more skillful the surgeon becomes Depending on the options that a hospital chooses to purchase, the cost of a da Vinci system can range between 1 million and 3 million dollars with the associated sales taxes. As with all surgical instruments, there are also disposable items needed during a surgery associated with equipment-specifically the da Vinci which must also be purchased. These items range from $1,000 to $3,000. Finally, as with many pieces of sophisticated electronic technology. It must be $200.000 a year. In addition to these specific costs on that this equipment occupies as well as utilize all the must be m ined The maintenance costs can be upwards to addition to these specific cost hospitals must continue to maintain the surgical men occupies as well as utilize all other supplies that would be used in any utca The Deal: A local hospital in the Pupet Sound area faced a dilemma in the medical arms race. Surrounding hospitals were purchasing and willing the da Vinci robot system. Management began to worry about the erosion of patients that would seek out this modern technology over more traditional surgical procedures. To this end a strategic decision was made to acquire the da Vinci robotic surgical system. The following data was presented to an analyst in the Finance Department for review Table Lease Term: 36 Months Lease Payment: $68,742.10 Purchase Price: $1.900000.00 Quite often, analysts are provided leasing information by the leasing company. Hospitals may choose to purchase equipment outright or acquire equipment using a lease. Leases are generally considered operating or capital leases under current accounting rules. Hospitals may purchase equipment outright if they have sufficient capital money that can be used to purchase equipment of significant amount-usually greater than $5,000). Otherwise, they may decide that if the interest rate of payments being charged is lower than their internal cost of capital (debt financing, equity financing, etc.), they may utilize the lease directly from the equipment seller. Given the information provided in Table : 1. What is the annual rate of interest beine charped to the hospital? The total interest paid over the entire term of the lease? 2. Given this rate of interest. give some reasons on why or why not the hospital should accept this lease contract. Is this a good deal for the lessee? 3. Why would a hospital care whether it was a collease or an operating lease?
