Answer:
147
Step-by-step explanation:
We want to find the value of a² + √b, so let's plug in 12 for a and 9 for b:
a² + √b
12² + √9
The square root of 9 is 3 because 3 * 3 = 9, while the square of 12 is 144 because 12 * 12 = 144.
144 + 3 = 147
The answer is thus 147.

Answer:
- Part a → dv/dt = 24 cm³/per second
- Part b → dv/dt = 1176 cm³/per second
Step-by-step explanation:
As all edges of a cube are expanding at a rate of 2 centimeters per second.
i.e ds/dt = 2 cm/s
The formula of volume of cube: V = s³
Differentiating the volume:
dv/dt = 3s²
Write ds/dt following derivative of volume
dv/dt = 3s² ds/dt
plug in the value: ds/dt = 2 cm/s
dv/dt = (3s²) (2)
dv/dt = 6s²
Given the edge is 2cm.
so plug in the value: s=2
dv/dt = 6s²
= 6(2)²=6(4)=24 cm³/per second
SIMILARLY,
When the edge is 14cm
dv/dt = 6s²
plug in the value: s=14
dv/dt = 6s²
= 6(14)²=6(196)=1176 cm³/per second
Thus,
- Part a → dv/dt = 24 cm³/per second
- Part b → dv/dt = 1176 cm³/per second
