I would say true. Hope this helps :)
Answer:
he can make 15 combinations
Step-by-step explanation:
Answer:
2/4 or 1/2
Step-by-step explanation:
Divide both sides by 2 and you get x=2/4. You can simplify further by dividing 2 and 4 by 2 to get 1/2
Answer:
Answer choice C
Step-by-step explanation:
Adding zero doesn't changed the sum, therefore doesn't change the median
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
