Explain the relationship between the area and the radius of a circle.
Bess [88]

Area of a Circle: The area of a circle is the amount of space the circle takes up. To compute the area of a circle, we use the formula a=πr^2 where r is the radius of the circle.

Radius: The radius of a circle is the distance from the center of the circle to any point on the circle.

Plz help me find answer. what are the coordinates of slope when y= x/1–x² when dy/dx=1​
vova2212 [387]

Step-by-step explanation:

dy/dx

= d/dx [x / (1 - x²)]

= [(1 - x²)(1) - (x)(-2x)] / (1 - x²)²

= (1 + x²) / (1 - x²)².

When dy/dx = 1, (1 + x²) / (1 - x²)² = 1.

=> 1 + x² = 1 - x²

=> 2x² = 0, x = 0.

Also when x = 0, y = (0) / [1 - (0)²] = 0.

Hence the coodinates is (0, 0).

Solve the system using elimination. 5x = –25 + 5y 10y = 42 + 2x
Serga [27]
<span>5x = –25 + 5y ---> 5x - 5y = -25 (1)
10y = 42 + 2x </span>---> 2x - 10y = -42 (2)
divide equation (2) by 2
so
x - 5y = -21

now you have
5x - 5y = -25
x - 5y = -21
-----------------subtract
4x = -4
  x = -1

substitute x = -1 into 5x - 5y = -25
5x - 5y = -25
5(-1) - 5y = -25
-5 - 5y = -25
-5y = -20
   y = 4

answer
(-1 , 4)
