What is Trigonometric Identity?

Trigonometric Identities are based on the trigonometric ratios used to solve Trigonometric equations.

The steps used to solve the trigonometric identity are :

Step 1 :  sin(x+y)

Step 2: cos ((π/2) - (x+y))

Step 3 : cos ( (π/2 -x) -y)

Step 4 : cos (π/2 -x) cosy + sin (π/2 -x)siny

Step 5: sinxcosy+cosxsiny

Therefore,the correct step is cos (π/2 -x) cosy + sin (π/2 -x)siny  and not cos (π/2 -x) cos(-y) + sin (π/2 -x)sin(-y) , the incorrect step is Step 4.

A submarine descends to a depth of 600 feet below the surface in 10 minutes. At this rate, what integer represents the change, in feet, of the submarine's position after one minute?
I really need help.​

Answers

A submarine descends to a depth of 600 feet below the surface in 10 minutes. At this rate, what integer represents the change, in feet, of the submarine's position after one minute?

First you need to list what you're given.

A submarine descends to a depth of 600 ft below the surface in 10 minutes. The question is asking for the change of the submarine's position after one minute. This can be represented as fractions in terms of [tex]\frac{distance}{time}[/tex].

[tex]\frac{600}{10} = \frac{x}{1}[/tex]

You're looking for the value of x. First you need to cross-multiply.

[tex]600 \times 1 = 10 \times x\\600=10x[/tex]

Since you're looking for x alone, you need to divide both sides by 10. This will eliminate the 10 since x is being multiplied by 10, and 10 divided by 10 is 1, making it 1x or x.

[tex]\frac{600}{10} = \frac{10x}{10}[/tex]

[tex]60=x[/tex]

That means the submarine is descending at a rate of 60 feet per minute, which can be represented as -60.

If you're looking for the submarine's position after one minute, all you have to do is subtract 60.

600 feet below surface is represented as -600.

[tex]-600-60=-660[/tex]

The submarine's position after one minute is 660 feet below surface(-660).

Manuel has 5/8 of a pizza to share equally with his brother. What fraction of the original pizza will each person receive?

Answers

Answer:

1¼

Step-by-step explanation:

⅝ ÷½

=⅝ײ/1

=⁵/4

=1¼

Whenever you divide two fractions you rewrite it switching the division sign for multiplication and writing the reciprocal of the second fraction.

A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.

5/8 of the pizza is equally shared between two people.

The fraction of the original pizza that each person receives is 5/16 of the pizza.

What is a fraction?

A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

Amount of pizza = 5/8

Equally shared between two people:

= 5/8 ÷ 2

= 5/(8x2)

= 5/16

This means that the fraction of the original pizza that each person receives is  5/16 of the pizza.

Thus,

5/8 of the pizza is equally shared between two people.

The fraction of the original pizza that each person receives is  5/16 of the pizza.

Based on experience, Farmer Fern knows that 15% of her eggs will be damaged in
route to the stores. In a sample of 100 eggs, what is the probability that less than
13% will be damaged?

Answers

Answer: 0.2877

Step-by-step explanation:

Given : The proportion of eggs will be damaged in route to the stores = 15% = 0.15

Sample size = 100

Let p be the probability of her eggs will be damaged.

The probability that less than 13% will be damaged is given by :-

[tex]P(p<0.13)=P(\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}<\dfrac{0.13-0.15}{\sqrt{\dfrac{0.15\times(1-0.15)}{100}}})[/tex]

[tex]=P(z<-0.56)[/tex]

[tex]=1-P(z<0.56)\\\\= 1-0.7123\\\\= 0.2877[/tex]

Hence, the required probability = 0.2877

If you like writing this one is for you. The City of Clear Lake signed a lease agreement with Mountainside Builders whereby Mountainside will construct a new office building for city administrative use and lease it to the City for 30 years. The fair market value of the building is $12 million. The City has agreed to make an initial payment of $822,441 and annual payments in the same amount for the next 29 years.

The lease includes a funding clause, which allows Clear Lake to terminate the lease agreement if the government does not appropriate funds for the lease payments. Clear Lake does not intend to exercise this option unless there is a financial emergency. Upon completion, the building had an appraised value of $13 million and an estimated useful life of 40 years.
