Answer:

V(s) = 332,9 m³

Step-by-step explanation:

The volume of a sphere is:

V(s) = (4/3)*π*r³

if we know  r  = 4,3 m then

V(s)  = (4/3)*3,14*(4,3)³

V(s)  = 332,8693 m³

Rounding the answer to the nearest tenth

V(s) = 332,9 m³

Y=6x-1, y=3x-4 the solution is_____
TEA [102]

Answer:

y= -7 and x= -1

Step-by-step explanation:

To do this, line up the variables so it looks like this...

y-6x=-1

y-3x=-4

The reason why -6x and -3y changes to negative is because that it moved to the other side of the equation.

distribute negative to the bottom equation because the two equations have the same number variable which is y...

y-6x=-1

-y+3x=4

Y cancels out and it will be left with -3x = 3.

X = -1.... plug that in to any of the two equation and you get y = -7.

Hope I helped and have a nice day!!

What is the average rate of change of the function f(x)=20(14)xf(x)=20(14)x from x = 1 to x = 2? Enter your answer, as a decimal
Advocard [28]
The average rate of a function f(x) over an interval x = a and x = b is given by:

Average \ Rate \ of \ Change= \frac{f(b)-f(a)}{b-a}

Given the function

f(x)=20(14)^x

The average rate of change from x = 1 to x = 2 is given by:

\frac{f(2)-f(1)}{2-1} = \frac{20(14)^2-20(14)^1}{1}  \\  \\ =20(196-14)=20(182)=3,640

Find the value of x.
faust18 [17]

Answer:

          7 sqrt(3) =x

Step-by-step explanation:

We know that sin 60 = opposite / hypotenuse

                       sin 60 = x/14

Multiply both sides by 14

                          14 sin 60 = x

                        14 * (sqrt(3)/2) =x

                      7 sqrt(3) =x
