Answer:
-25
Step-by-step explanation:
h(j) = -j^2-6j+2 Let j =3
h(3) = -3^2-6(3)+2
= -9 -18+2
= -27+2
= -25
The hypotenuse MO is found from the Pythagorean theorem to be
MO = √(12² + 5²) = √(144+25) = √169 = 13
The sine of angle O is the ratio of the opposite side (MN=12) to the hypotenuse (MO=13). The appropriate choice is ...
C. 12/13
Answer:
20 km/h
Step-by-step explanation:
Zoey rode a total of 120 km (there and back) in a total time of 6 hours (=2.5+3.5). Her average speed is given by ...
speed = distance/time = (120 km)/(6 h) = 20 km/h
Answer:
see below for a graph
Step-by-step explanation:
One point can be plotted at the y-intercept: (0, -2). Since the slope tells you the line drops 3 units for each 2 units to the right, the point (2, -5) will be another point on the line. The graph will go through those two points.
