The standard equation of a circle:

(y-k)² + (x-h)² = R² (1), where R is the radius and h, k are the coordinates of the center.: C(h, k)
In the problem the coordinates of the center C(2,-1).
Replace in (1)  h by 2 and k by -1:

(y+1)² + (x-2)² = 25

What is −30−6r= -36 ?
Nadya [2.5K]

-30-6r=36

We move all terms to the left:

-30-6r-(36)=0

We add all the numbers together, and all the variables

-6r-66=0

We move all terms containing r to the left, all other terms to the right

-6r=66

r=66/-6

r=-11

A family has traveled 114 miles of a planned trip. This is 37% of the total distance they must travel on the trip. Find, correct
denis23 [38]

Answer:

The total distance they will travel on their trip is 308 miles.

Step-by-step explanation:

This question can be solved using a rule of three.

114 miles is 37% = 0.37. How many mines are 100% = 1?

114 miles - 0.37

x miles - 1

0.37x = 114

x = \frac{114}{0.37}

x = 308.11

Rounding to the nearest mile

The total distance they will travel on their trip is 308 miles.

PLEASE HELPPPPP!!!!!!!!! (show work if you can)
Kryger [21]

Answer:

180x^4y^3z^2

Step-by-step explanation:

Start by finding the LCM of the coefficients of each polynomial:

LCM(12,18,30)=180

Next, to find the least common multiple of each of the following terms, we need to take the absolute minimum we can of each term (x, y, and z). The largest term of x is x^4 in the first polynomial, so we'll take exactly that for our x term in the LCM, absolutely nothing more. Similarly, the largest term of y in any of the three polynomials is y^3 (also in the first polynomial) and the largest z term in any of the three polynomials is z^2 in the second polynomial. Thus, the LCM of all our polynomials is:

180\cdot x^4\cdot y^3\cdot z^2=\boxed{180x^4y^3z^2}

INCREDIBLY URGENT!
klemol [59]

Answer:

a) By graphing just one interval of length T. b) Infinite number of angles, c) Infinite times.

Step-by-step explanation:

Any function is periodical when:

f(t) = f(t+i\cdot T), \forall i \in \mathbb{N}_{O}

Where T is the period of the function. The periodicity of the function allows us to limit the graphing of the function to just an interval of one period and according to the definition, you can expect same output with n different angles (infinite number of angles and same output infinite times).
