Use trigonometric identities to verify each expression is equal. csc2(x) - 2csc(x)cot(x) + cot2(x) = tan2(x/2)

Answers

By definition of csc and cot,

csc²(x) - 2 csc(x) cot(x) + cot²(x) = …

… = 1/sin²(x) - 2 cos(x) / sin²(x) + cos²(x) / sin²(x)

Combining fractions,

… = (1 - 2 cos(x) + cos²(x)) / sin²(x)

Factorize the numerator and use the Pythagorean identity,

cos²(x) + sin²(x) = 1,

to rewrite the denominator.

… = (1 - cos(x))² / (1 - cos²(x))

Cancel a factor of 1 - cos(x).

… = (1 - cos(x)) / (1 + cos(x))

Using the half-angle identities,

sin²(x) = (1 - cos(2x))/2

cos²(x) = (1 + cos(2x))/2

it follows that

1 - cos(x) = 2 sin²(x/2)

1 + cos(x) = 2 cos²(x/2)

and so

… = (2 sin²(x/2)) / (2 cos²(x/2))

… = sin²(x/2) / cos²(x/2)

Finally, by definition of tangent,

… = tan²(x/2)

Pauline chasse has just signed a lease agreement with landlord, wayne godbrey to rent a house he owns in delano. The lease states definite beginning (january 1, 2016) and ending (october 30, 2016) dates, and sets forth the rent amount and due dates and all additional property and personal information required in such a lease. Wayne hands a copy to pauline, but she notices that he has not signed it. When she comments about this to him, he tells her that signatures are not necessary since the lease is for less than a year. Which of the following is true of this situation?.

Answers

The correct option that is true as regards Wayne's situation about the lease is;

B; Leases of less than one year are not required to be in writing. However, if a lease IS in writing, then it must be signed by the lessor (in this case, Wayne).

The missing options are;

Under the Statute of Frauds in California,

A) leases of less than one year are not even required to be in writing, and therefore, signatures are not required.

B) Leases of less than one year are not required to be in writing. However, if a lease IS in writing, then it must be signed by the lessor (in this case, Wayne).

C) Leases of less than one year are not required to be in writing; but if there is a written lease, then it must be signed by both the lessee and lessor.

D) Because the property being leased is located in Northern California, a lease agreement is required to be both written and signed by the lessor if the lease period is for 6 months or more

Now, California has some principles that guide the regulation of the real estate industry and according to the California Principles of Real State, it has to be said that leases of less than one year are not required to be in writing.

Now, even though the law stated that the consent of both parties are not enough to bind themselves in the lease agreement, it is recommended that just for the sake of keeping things legally binding as regards the agreement between both parties, then both parties may state it in written and the lessor must sign it.

Properties of protein is least likely to be affected by change in ph.

Answers

Answer:

Given

Rate of interest = 10% per annum

Principal for the first year = Rs 6000

Interest for the first year = Rs (6000 × 10 × 1) / 100

= Rs 600

Amount at the end of first year = Rs 6000 + Rs 600

= Rs 6600

Principal for the second year = Rs 6600

Interest for the second year = Rs (6600 × 10 × 1) / 100

= Rs 660

Amount for the second year = Rs 6600 + Rs 660

= Rs 7260

Therefore, compound interest for 2 years = final amount – (original) Principal

= Rs 7260 – Rs 6000

We get,

Permeable groundwater occurs when water infiltrates the ground due to rocks exhibiting spaces (pores) between their grains.
