Answer:

B. and D.

Step-by-step explanation:

B.:

The top shape is a hemisphere (half sphere) and the bottom shape is a cone.

Hemisphere:

V=[(4/3)pi*r^3]/2

V=[(4/3)pi*5^3]/2

V=[(4/3)pi*125]/2

V=523.333/2

V=261.6667

Cone:

V=1/3*pi*r^2*h

V=1/3*pi*5^2*10

V=1/3*pi*25*10

V=261.6667

Added together is about 523.3 cubic feet.

Find the equation in standard form , of the line passing through points (2,-3) and (4,2)

Fudgin [204]

The form of linear equation that describes line is:

$y=sx+n$

First we must calculate the slope.

$s=\dfrac{\Delta{y}}{\Delta{x}}=\dfrac{2-(-3)}{4-2}=\dfrac{5}{2}$

Now it looks a bit more like this:

$y=\dfrac{5}{2}x+n$

All we need now is to put in y and x from one point doesn't matter which. I'll pick A.

The equation now looks like this:

$-3=\dfrac{5}{2}\cdot2+n$

Solve for n.

$-3=5+n \\n=-8$

And finally write the equation.

$f(x)=\dfrac{5}{2}x-8$

Hope this helps.

How many solutions does each equation below have? how can you tell?

Vikki [24]

A) This one has no solutions because the answer of the equation is 0=-1 which isn't true.

b) 6t-3=3t+6 ==> 3t=9 ==> t=3 This means that this has one solution.

c) 6 (2m-3)-3m=2m-18+m ==> 12m-18=2m-18+m ==> 9m=0 ==> m=0 so this one has no solutions.

d) 10+3y-2=4y-y+8 ==> 8+3y=3y+8 ==> 0=0 ==> Infinitely many solutions.

~Hope I helped!~
