Answer:

  • Option 4

Step-by-step explanation:

Midpoint of the diameter is the center.

<u>Use midpoint formula to determine the coordinates:</u>

  • x = (2 - 4)/2 = -1
  • y = (5 + 13)/2 = 9

<u>Find the radius using the midpoint and one of the endpoints and the distance formula:</u>

  • r = \sqrt{(-1 - 2)^2 + (9 - 5)^2}  = \sqrt{9+16} = \sqrt{25} = 5

<u>Use the equation of the circle:</u>

  • (x - (-1))² + (y - 9)² = 5²
  • (x + 1)² + (y - 9)² = 25

Correct choice is 4

The arnold family arrived at the beach at 10:30 A.M.

10:30 

Add 3 hours and 3/4 minutes to that

3/4 = 75% of 60

.75 * 60 = 45

3 hours and 45 minutes 

10:30 >> 3 hours more = 1:30
1:30 + 45 mins = 2:15

Answer would be: They left at 2:15

Answer:

b = y-intercept; The equation is y = mx + b. The x and y variables remain as letters, but m and b are replaced by numbers (ex: y = 2x + 4, slope = 2 and y-intercept = 4). The following video will show a few examples of understanding how to use the slope and intercept from an equation.

Vertex (4, -13) y = x^2 - 8x + 3 x-coordinate of vertex: x = -b/(2a) = 8/2 = 4 y-coordinate of vertex: y(4) = 16 - 32 + 3 = -13 Vertex (4, -13) To find y-intercepts, make x = 0 --> y = 3 To find x-intercepts, solve the quadratic equation y = 0 Use the improved quadratic formula D = d^2 = b^2 - 4ac = 64 - 12 = 52 --> d = +- 2sqrt13 There are 2 x-intercepts (2 real roots): x = -b/(2a) +- d/(2a) = 8/2 +- (2sqrt13)/2 = 4 +- sqrt13 graph{x^2 - 8x + 3 [-40, 40, -20, 20]}
