The correct answer is C) 12
Euler's formula states that the number of vertices subtracted by the number of edges and added to the number of faces of a polyhedron always equals 2:
V - E + F = 2
We have 24 edges and 14 faces:
V - 24 + 14 = 2
Combining like terms,
V - 10 = 2
Add 10 to both sides:
V - 10 + 10 = 2 + 10
V = 12
Answer:
m=17
Step-by-step explanation:
$15 minus $0.14(# minutes) = $12.62
15 - .14m = 12.62
.14m = 15 - 12.62
.14m = 2.38
m = 2.38/.14
m = 17 minutes
Answer: D. 10.83
Step-by-step explanation: 3.6/6=6.5/x x~10.83
Answer:
Center ( 4 , -2) and r = 6
Step-by-step explanation:
x² - 8x + y² + 4y - 16 = 0
x² - 8x + y² + 4 y = 16
x²- 2*4x + y² + 2 *2y = 16
(x² - 2*4x + 16 ) - 16 + (y² + 2*2y + 4) -4 = 16
(x - 4)² + (y + 2)² = 16 + 16 + 4
(x - 4)² + (y -[-2])² = 36
(x- 4)² + ( y - [-2] )² = 6²
Compare with (x - h)²+ (y - k)² = r²
Center ( 4 , -2) and r = 6
Answer:
I think it is B.
Step-by-step explanation:
the number on the x-axis is placed at the numerator and the number on the y-axis is placed at the denominator.
the line crosses the point (2,1.5)
