What is the standard equation of the circle in the graph?

Answers

Answer 1
Answer:

Answer:

Standard Equation Of Circle is (x-h)^2+(y-k)^2+r^2

Step-by-step explanation:

Let we are given a circle in graph with center P whose coordinate are ( h , k ) and radius of the circle is r units.

Then the standard equation of circle is written as ,

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

If center becomes origin then, Equation become

x^2+y^2=r^2
Answer 2
Answer: x^2 + y^2 = radius^2
Is that what your adking for? This is for a circle around the origin.

Which best describes the solution set for the compound inequality below? (pick the best answer)2(x + 7) – 1 > 15 or 3(x + 2) < 2x + 7
A. no solution
B. x = 1
C. all real numbers except x = 1
D. all real numbers

Answers

2(x + 7) - 1 > 15                 3(x + 2) < 2x + 7
2x + 14 - 1 > 15                  3x + 6 < 2x + 7
2x + 13 > 15                       3x - 2x < 7 - 6
2x > 15 - 13                        x < 1
2x > 2
x > 2/2
x > 1

so, x > 1 OR x < 1.....all real numbers except 1

An isosceles triangle has base angles that each measure 48°. Which equation can be used to find x, the measure of the third angle of this isosceles triangle in degrees?

Answers

Answer:

Step-by-step explanation:

It would be 48+48+x=180, since 3 angles in any triangle will always measure 180, by definition of a triangle. I guess you could also do 2(48)+x=180, but the first equation just makes it more intuitive I guess. The reason why this works is because since 3 angles must equal 180, the missing angle, x, must be the value of 180-48-48, since that would be the remaining value needed to make a triangle

Answer:

LM = 2(MP)

Step-by-step explanation:

The radius KN is perpendicular to LM meaning that the line is split in half at the crossing. Review properties of circles to see why this is true.

Since we know this, we can say LM = LP + MP. And LP = MP.

So we can say LM = 2(MP).

A father is four times as old as his daughter. In 18 years he will be two times as old as she. How old is the daughter now?

Answers

Let's say x to the daughter's age, since the father's age is four times the daughter's age, his age will be 4x. 18 years later, the daughter's age will be x+18 and the father's will be 4x+18. And we know that 18 years later the father's age will be twice the daughter' so , 4x+18 = 2(x+18) and 4x+18=2x+36 then, 4x-2x=36-18,
2x=18 then divide both sides by 2, x = 9. The daughter's age was x, so she is 9 years old.

That is the simplest form as possible. Because 15 can only be divisible by 5 and 3 but 3 and 5 don't go into 56
