It has been 1 hour and 20 minutes.

HOW I FOUND MY ANSWER:

7:10 to 8:10 = 1 hour

8:10 to 8:30 = 20 minutes

(1 hour + 20 minutes = 1 hr and 20 min.)

HOPE THIS HELPED

I need to find angle M
nadezda [96]

Answer:

m<AIR = 90 deg

Step-by-step explanation:

I assume the problem contains an error, and that AR is a diameter, not AC.

Look at the diameter of the circle, AR. It passes through the center of the circle, C. You can think of the two radii of the circle, CR and CA, as sides of angle RCA. Since AR is a diameter, and AR is a segment which is part of line AR, rays CR and CA are sides of an angle that lie on a line. That makes the measure of angle RCA 180 deg. Angle RCA is a central angle of circle C since its vertex is the center of the circle.

Angle AIR is an inscribed angle in circle C since its vertex is on the circle itself. If an inscribed angle and a central angle intercept the circle at the same two points, then the measure of the inscribed angle is half the measure of the central angle.

m<AIR = (1/2)m<RCA = (1/2) * 180 = 90

m<AIR = 90 deg

59. What happens to the graph of y = |x| when the equation changes to y = |x + 4? A The graph shifts up 4 units. The graph shift
marishachu [46]

Answer: Graph shifts 4 units to the left

Explanation:

I'm assuming you meant to say y = |x+4|

If so, then the graph shifts 4 units to the left. Replacing x with x+4 moves the xy axis 4 units to the right if we held the V shape in place (since each x is now 4 units larger). This gives the illusion the V shape is moving 4 units to the left.

Or you could look at the vertex point to see how it moves. On y = |x|, the vertex is at (0,0). It then moves to (-4,0) when we go to y = |x+4|
