What is the standard form of the equation of a circle whose diameter is 20 units and whose center is (−1,7)?

Mathematics
1 answer:
VARVARA [1.3K]3 years ago
4 0

Answer:

(x + 1)^2 + (y - 7)^2 = 100

Step-by-sep explanation:

Given:

Diameter of circle = 20 units

Center of circle = (-1, 7)

Standard form of the equation of a circle is expressed in the center-radius form as:

(x - h)^2 + (y - k)^2 = r^2,

Where,

h = -1

k = 7

r = ½ of diameter = ½(20) = 10 units

Plug in the values into the equation

(x - h)^2 + (y - k)^2 = r^2

(x - (-1))^2 + (y - 7)^2 = 10^2

(x + 1)^2 + (y - 7)^2 = 100

What elements are required for a legally valid contract?
ella [17]

Answer:The 5 elements of a legally binding contract are made up of:

An offer.

Acceptance,

Consideration.

Mutuality of obligation.

Competency and capacity.

Sometimes additional components are involved to protect the interests of all the parties.

A contract involves two or more parties who are competent to enter into a legally binding agreement. While a contract can be verbal or implied, it is usually in writing. If a contract is enforceable, a court can compel the parties to follow through on what they agreed to in the contract.

A legally enforceable contract is more than a casual promise between friends. The purpose of a business contract is to place legal requirements on the parties to follow through on the agreement. The legal system is available to mediate if a party breaches the terms of the contract.

Victor has saved $89.25 for the bicycle that he wants. The bicycle costs $129.85. Victor
serious [3.7K]

Answer:

Victor's equation did not correctly model the problem.

The equation that correctly modeled the problem:

$129.85-$89.25=$40.60

Step-by-step explanation:

The amount required for bicycle purchase by Victor is $129.85 out of which $89.25 has been saved,in other words,the balance required for Victor to reach his target purchase price is the difference between the total cost of $129.85 and the $89.25 already saved.

The balance required=$129.85-$89.25=$40.6

This shows that the equation put forward by Victor is wrong.

An equation that correctly represents the problem is the difference between the target savings and the amount already saved as stated above
