Answer:
Diameter of cylinder = 12 cm
Step-by-step explanation:
Given:
Height of cylinder = 5 cm
Total surface area of cylinder = 3 x [Curved surface area of a cylinder]
Find:
Diameter of cylinder
Computation:
Total surface area of cylinder = 3 x [Curved surface area of a cylinder]
πr²h = 3[2πrh]
πr²h = 6πrh
Radius of cylinder = 6 cm
Diameter of cylinder = 2 x Radius of cylinder
Diameter of cylinder = 2 x 6
Diameter of cylinder = 12 cm
Answer: yes, because it is useful to describe changes in the behavior of the thing we are describing.
Step-by-step explanation:
A piecewise function f(x) is a function that is "different" depending on the range of the values of x, this is for example:
y = x -----> if x < 0
y = x^2 ----- if x ≥ 0
This is used to represent changes in the behavior of the thing we are describing.
For example, suppose an object that is moving with constant velocity, the velocity graph will be a constant line.
Now, the object suddenly, at a time t = t0 accelerates to a constant acceleration A, now the graph of the velocity is a linear graph with slope equal to A.
So this situation can be represent this with a piecewise function:
V(t) = c -----> if t < t0
V(t) = c + A*t -----> if t ≥ t0
So the answer is yes, we can.
You will divide by 2 on each sides then x will be your answer
So x is greater than or equal to 4
You <em>multiply</em> both sides of the first equation by 4.
Then you have . . .
-2x + 4y = 3 and y - 2x = 3 .
If you want to get rid of a fraction, you multiply it by itsdenominator.
BUT ... whatever you do to one term on one side of the equation, you
have to do the same to <em>all</em> the terms on that side, AND then you have to
do the same thing to all the termson the OTHER side.
Answer:
Answer in simplified mixed form is 1 5/6
Step-by-step explanation:
We need to solve: -6 7/8 divided by (-3 3/4)
This can be written as:
-6 7/8 ÷ (-3 3/4)
Since -6 7/8 = -55/8 and -3 3/4 = - 15/4
So we can write :
-6 7/8 ÷ (-3 3/4) = -55/8 ÷ (-15/4)
or (-55/8 ) / (-15/4)
or (-55/8) * (-4/15)
or -(-220/120)
or 11/6
or 1 5/6 , this is the answer
We got the answer in simplified mixed form is 1 5/6
