Step-by-step explanation:
sue = 18 sweets
tony= 18 sweets
(sue) S= (18 - x)-5
(tony) T=(18 + x) ÷ 2
hope this helps :)
Answer:
2x(2x-1)
Step-by-step explanation:
Answer:
<QOS =150°(opp. <'s of a cyclic quard)
<QRS=75°(< at centre =2×< at circumference)
I don't know about the third one bro
Maybe there's an erroron that quation
We are given with the following given
dV/dt = 35 m3/min
h = (3/2)D
What is asked is
dr/dt at t = 7 min
The volume of a cone is
V = (1/3)πr²h
From the given
h = (3/2)D
since D = 2r
h = 3r
Subsituting
V = πr³
At t = 7 min, the volume is
V = 35(7)
V = 245
and the radius is
245 = πr³
r = 4.27
Differentiating the volume
dV/dt = 3πr² dr/dt
From the given
dV/dt = 35
Subsituting
35 = 3πr² dr/dt
So,
dr/dt = 0.20 m/s
and
dh/dt = 0.60 m/s
