Canister is a cylinder

\\ \rm\rightarrowtail V=\pi r^2h-3(\dfrac{4}{3}\pi r^3)

\\ \rm\rightarrowtail V=\pi r^2h-\dfrac{12}{3}\pi r^3

\\ \rm\rightarrowtail V=\pi r^2h-4\pi r^3

  • Take πr^2 common

\\ \rm\rightarrowtail V=\pi r^2(h-4r)

Answer:

\implies V=\pi r^2(h-4 r)

Step-by-step explanation:

Volume of the canister LESS the volume of 3 tennis balls:

V=\pi r^2h-3\left(\dfrac43\pi r^3\right)

Expand brackets:

\implies V=\pi r^2h-4\pi r^3

Factor:

\implies V=\pi r^2(h-4 r)

drek231 [11]

Answer:

The answer to your question is  x² + 5/2x - 3/2 = 0

Step-by-step explanation:

Data

Quadratic equation           x² + 2.5x - 1.5 = 0

Process

1.- Convert the decimals into fractions

2.5 = 25/10 = 5/2

1.5 = 15/10 = 3/2

2.- Substitution

                                       x² + 5/2x - 3/2 = 0

3.- Conclusion

I rewrite the equation, now it is expressed in fractions. It could be solve by factoring.

What is the domain of the function f(x) = 2x /(3x^2− 3
Svet_ta [14]
The domain of the function in this case will be for when the denominator is different from zero:
 3x ^ 2- 3 = 0
 3x ^ 2 = 3
 x ^ 2 = 3/3
 x ^ 2 = 1
 x = + / - 1
 Therefore the domain of this function are all reals without including x = 1 and x = -1

What is the equation in slope intercept form?
patriot [66]

Answer:

Step-by-step explanation:

The line has a slope of -1/3. For lines to be perpendicular there product must equal negative 1

m1(m2)=-1

-m/3=-1

m=3

So we know our line has a slope of three so

y=3x+b, we can solve for the y intercept, b, using point (-2,8)

8=3(-2)+b

8=-6+b

b=14, so our line is

y=3x+14
