Answers

Answer 1

Answer:

1

Step-by-step explanation:

If a term does not have a written coefficient, then the coefficient is one.

This is because 1(y) = y

Answer 2

Answer:

1

Step-by-step explanation:

there is an "understood" 1 as the coefficient of any blank variable

but it is useless to write since anything times 1 is just the same number ..... (i.e: y *1= y...same as 5 * 1= 5)

Step-by-step explanation:

Using the sine ratio in the right triangle

sin40° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{26}{c}[/tex] ( multiply both sides by c )

c × sin40° = 26 ( divide both sides by sin40° )

What is the height, x, of the equilateral triangle?

an equilateral triangle with the angles labeled as 60 degrees and a side length of 14 inches, the height labeled as x

Answers

Answer:

x = [tex]7\sqrt{3} [/tex] inches

Step-by-step explanation:

- 2021 Edmentum

The height x of the equilateral triangle is 7√3 inches.

What is an Equilateral triangle?

Equilateral triangles are triangles that have all their sides and angles equal to each other. The three angles are 60 degrees each.

Therefore,

The side length of the equilateral triangle is 14 inches.

Therefore, To find the height of the triangle using the Pythagoras theorem.

c² = a² + b²

14² - 7² = b²

b² = 196 - 49

b² = 147

b = 7√3

Hence, The height x of the equilateral triangle is 7√3 inches.

The Town Theater receives $4212 by selling 465 tickets to
the opening night of the revue. If the full price of a ticket is $10.00
and discount tickets for students and seniors are $8.00 each, how
many discounted senior/student tickets were sold?

Answers

Answer:

219

Step-by-step explanation:

let x be the number of full price tickets and y be student/ senior number , then

x + y = 465 → (1)

10x + 8y = 4212 → (2)

Multiplying (1) by - 10 and adding to (2) will eliminate x

- 10x - 10y = - 4650 → (3)

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

0 - 2y = -438

- 2y = - 438 ( divide both sides by - 2 )

y = 219

The number of senior/ student tickets sold was 219

1900 is deposited into a savings account. Interest is compounded annually. After 1 year, the value of the account is 1957. After 2 years, the value of the account is 2015.71. This scenario can be represented by an exponential function of the form f(x)=1900(b)^2 , where is the amount in the savings account, and x is time in years. What is the value of b?

Answers

Answer:

1.03

Step-by-step explanation:

2015.71 = 1900(b)^2

44.896659 = 43.588989 * b

44.896659/ 43.588989 = b

1.0300000 = b

Recall ; for an exponential distribution :

b In the equation = 1 + r ; where, r = rate

b = 1 + r

1.0300000 = 1 + r

r = 1.0300000 - 1

r = 0.03

Hence, the value of b in the equation is 1.03

Jack and charlie each deposit $17,250 into accounts that earn 6% interest for 6.5 years. Jacks account earns annual compound interest. Who will earn more interest after 6 years, and how much more interest will they earn?

Answers

From the amounts found using simple and compound interest formulas, we found that Carlie earns more interest than Jack by $1009.45.

What is the difference between simple and compound interests?

Simple interest is based on the principal amount, which is the main distinction between it and compound interest. Contrarily, compound interest is calculated using the principle sum and interest that has been compounded over the course of a period. Simple interest is a predetermined proportion of the principal amount borrowed or lent that is paid or received over a set period of time. Borrowers are required to pay interest on interest in addition to principal since compound interest accrues and is added to the accrued interest from prior periods.

The complete question is given below.

Given,

  The principal amount deposited by both Jack and Carlie  P = $17,250

The rate of interest r = 6% = 0.06

The time period = 6.5

Jack's account earns annual simple interest and Carlie's account earns annual compound interest.

So the amount in each person's account after a time period of t = 6 years.

Jack:

Amount = P(1+rt) = 17250 ( 1 + 0.06*6) = $23,460

Carlie:

number of times compounded in a year n = 1

Amount = [tex]P(1 + \frac{r}{n})^{nt}[/tex] = 17250 ( 1+0.06)⁶ = $24,469.45

Therefore from the amounts found using simple and compound interest formulas, we found that Carlie earns more interest than Jack by $1009.45.

Please help me on this assignment Its importantDiana NyadMarathon Swimmer(1) On August 19, 1979, Diana Nyad began her historic swim from Bimini, Bahams, to Jupiter, Florida, 89 miles away. (2) Nyad, a veteran of several marathons swims, wants to set a new world record for the longest open-water swim. (3) In 1974 she swam across Lake Ontario from north to southa difficult crossing because of the swift current of the Niagara river. (4) A year later she completed a swim of more than 25 miles around New York Citys Manhattan Island, she had battled dangerous currents for nearly eight hours. (5) The swim from the Bahamas to Florida, however, would be far more treacherous than anything she had previously attempted. (6) It would require exceptional physical and mental strength.(7) Nyad, like other long-distance swimmers, knew that every marathon swim is a grueling physical experence. (8) In earlier marathons she had become delirious from the fatigue of continuous stroking, kicking, and breathing. (9) She also knew that her senses would become impaired. (10) Her dark goggles would fog over, making it impossible for her to see. (11) Even though her coach and crew were in a support boat only twenty feet away, the tight rubber swim cap that covered her ears would prevent her from hearing thecoachs whistle. (12) The salt water would even affect her senses of taste, touch, and smell.(13) In addition to extreme physical exhaustion, Nyad was aware of the many dangers she would face in the water. (14) During earlier marathons schools of jellyfish had repeatedly stung her. (15) On Nyads Bahamas-to-Florida swim, a shark appeared.(16) Nyads crew was prepared with an electronic shark shield. (17) Crew members sent out a wave of electricity that did not harm Nyad but affected the shark and cause them to turn away. (18) Electricity can be used to repel many other kinds of animals. (19) Despite all the obstacles she faced, Nyad successfully reached her goal. (20) She was exhausted but happy. (21) She waded onto the Florida shore.
