The answer is C. Because I guessed and need points to ask other ppl...
Answer:
Step-by-step explanation:
Given equation:
Equation:1
Equation:2
Multiplying equation:2 by 2 gives:
Equation:3
Subtracting Equation:3 from Equation:1
The negative sign outside the bracket changes the sign inside it after opening the bracket
Putting the value of 'y' in Equation:2
Answer:
the answer is 58 dear because there he couldn't figure out what he meant
From the diagram above
mixtures of 3 cups of red paints and 2 cups of green paints for 1 batch
this means for every one batch of brown paint
you have 3 cups of red paints and 2 cups of green paints
for three batches
3 red cups + 3 red cups + 3 red cups = 9 reds cup
2 green cups + 2 green cups + 2 green cups = 6 greens cup
to produce three batches you will need the mixture of 9 red cups of paints and 6 green cups of paint
adding to the diagram you will have 6 more red cups and 4 more green cups
Answer:
The volume is increasing at a rate of 1508 cubic millimeters per second when the diameter is 60 mm.
Step-by-step explanation:
Volume of a sphere:
The volume of a sphere is given by the following equation:
In which r is the radius.
Implicit derivatives:
This question is solving by implicit derivatives. We derivate V and r, implicitly as function of t. So
The radius of a sphere is increasing at a rate of 4 mm/s.
This means that
How fast is the volume increasing (in mm^3/s) when the diameter is 60 mm?
This is when . So
The volume is increasing at a rate of 1508 cubic millimeters per second when the diameter is 60 mm.
