Answer:
2/π ≈ 0.637 m/s
Step-by-step explanation:
The rate of change of area with respect to time is ...
A = πr²
dA/dt = 2πr·dr/dt
Filling in given values in the above equations, we can find r and dr/dt.
25π = πr² ⇒ r = 5
20 = 2π·5·dr/dt
dr/dt = 20/(10π) = 2/π . . . . meters per second
The radius is increasing at the rate of 2/π ≈ 0.637 meters per second.
Answer:
c
Step-by-step explanation
Factoring: 2x3-5x2+7x-6
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: 7x-6
Group 2: 2x3-5x2
so its c
Pull out from each group separately :
Group 1: (7x-6) • (1)
Group 2: (2x-5) • (x2)
Bad news !! Factoring by pulling out fails :
The groups have no common factor and can not be added up to form a multiplication.
Answer:
x = 14
Step-by-step explanation:
X / 2 = 7
Multiply by 2 to isolate x.
x = 7 * 2
x = 14
