Answer:
Step-by-step explanation:
x + 90° + 73° = 180° ( being linear pair)
x = 180° - 163 °
x = 17°

Answer:
C
Step-by-step explanation:
Answer:
D. y=-3x-6
Step-by-step explanation:
line slopes downwards by 3 and moves to the right by 1. this means the slope is -3. the line crosses the y axis at -6, so the equation for the line is -3x-6
Whooh
SA=4pir²
take derivitive
dSA/dt=8pir dr/dt
and do the volume as well
V=(4/3)pir³
dV/dt=4pir² dr/dt
we need to solve for dV/dt
to do taht we need dr/dt
so
dSA/dt=8pir dr/dt
given dSA/dt=3pi cm/sec
r=2
3pi=8pi2 dr/dt
3=16 dr/dt
3/16=dr/dt
now do the volume
dV/dt=4pir² dr/dt
r=2
dr/dt=3/16
dV/dt=4pi2² (3/16)
dV/dt=16pi(3/16)
dV/dt=3pi
nice
the volume of the sphere is decreasing at 3pi cm/sec as well
