Find the missing length of the triangle.

Mathematics
1 answer:
bearhunter [10]4 years ago
5 0

Answer:

29 km

Step-by-step explanation:

to find the hypothenuse of a triangle you can use the pythagorean theorem.

a^2 + b^2 = c^2

in this case 20 km would be a, 21 km would be b and they add up to 841, then you find the square root and get 29 km :)

The equation in standard form for the circle with radius 10 centered at the origin?
fenix001 [56]

Answer:

x^2 + y^2 = 100

Step-by-step explanation:

The standard form equation for a circle is:

(x – h)^2 + (y – k)^2 = r^2

Where h is the x coordinate of the center point and k is the y coordinate of the center point. Since the center point is (0,0), this simplifies to:

x^2 + y^2 = r^2

Since the radius is 10, this simplifies to:

x^2 + y^2 = 100

Nitella [24]

5p + 2,000,000 = 22,500,000

5p = 20,500,000

p = 20,500,000/5

p = 4,100,000 population in 1950

Can someone help me with this :/
slavikrds [6]

Answer:

2x² + x - 1 = 0

a= 2 b= 1 c= -1

x = [ -b +- sqr rt( b^2 -4ac) ] / 2*a

x = -1 +- sqr rt (1 - 4 *2*-1) / 4

x1 = [ -1 + (sqr rt (1 +8)) / 4

x1 = ( -1 + sqr rt (9)) / 4

x1 = (-1 + 3) / 4

x1 = .5

x2 = (-1 -3) / 4

x2 = -4 / 4

x2 = -1
