Find an equation of the circle that has center (-1,2) and passes through (5,-4).
kherson [118]
General equation for a circle
(x - a)² + (y - b)² = r²
with (a,b) represents the center, (x,y) represents one of the points lie on the circle, and r represents the radius

Determine r² by substituting the points into the general equation
(x - a)² + (y - b)² = r²
(5 - (-1))² + (-4 - 2)² = r²
(5 + 1)² + (-6)² = r²
6² + 36 = r²
36 + 36 = r²
72 = r²

Determine the equation of the circle
(x - a)² + (y - b)² = r²
(x - (-1))² + (y - 2)² = 72
(x + 1)² + (y - 2)² = 72 (This is the equation of the circle)

Answer:

  • b and e

Step-by-step explanation:

a. 5/2 ÷ 1/2  =

  • 5/2*2 =
  • 5

b. 6/9 ÷ 5/6

  • 2/3*6/5 =
  • 2*2/5 =
  • 4/5

c. 3/6 ÷ 2/5

  • 1/2 * 5/2 =
  • 5/4

d. 7 1/2 ÷ 6 =

  • 15/2*1/6 =
  • 5/(2*3) =
  • 5/6

e. 1 1/3 ÷ 1 2/3=

Can someone explain step by step how to do this and how to get the numbers please? HELP HELP HELP!!
Alexxandr [17]
A = 113.1
so the formula for the area of a circle is
A = pi x r^2
-pi is 3.14(rounded)

-r stands for the radius of the circle which is half the diameter so for this circle your r or radius is 6 and the radius is just squared

so when you plug the numbers in the formula it is
A = 3.14 x 6^2(squared)

A = 3.14 x 36

A = 113.1

expression to approximate log a of x for all positive numbers a, b, and x, where a is not equal to 1 and b is not equal to one
amid [387]

Question:

Approximate log base b of x, log_b(x).

Of course x can't be negative, and b > 1.


Answer:

f(x) = (-1/x + 1) / (-1/b + 1)


Step-by-step explanation:

log(1) is zero for any base.

log is strictly increasing.

log_b(b) = 1

As x descends to zero, log(x) diverges to -infinity


Graph of f(x) = (-1/x + 1)/a is reminiscent of log(x), with f(1) = 0.


Find a such that f(b) = 1

1 = f(b) = (-1/b + 1)/a

a = (-1/b + 1)


Substitute for a:

f(x) = (-1/x + 1) / (-1/b + 1)

f(1) = 0

f(b) = (-1/b + 1) / (-1/b + 1) = 1

Find sin(90°).<br><br> 45°<br> A.0<br> В.1<br> C. square 2 <br> D. square 2 / 2
otez555 [7]

Answer:

sin90° = 1.

Step-by-step explanation:

Using the diagram, we notice that the side opposite of the 90° angle is the hypotenuse itself.

Therefore sin90° = Hypotenuse/Hypotenuse = 1.
