Answer:

distance d(A,B)=1

Step-by-step explanation:

we know that if we have given two point $A(x_{1}, y_{1})$ and $and$ x_{2},y_{2})[/tex] we have to find the distance between two points d(A, B)

then we can use following formula

d(A,B) =[tex]\sqrt((x_{2}-x_{1})^2+(y_{2}-y_{1})^2)\\=\sqrt((9-8)^2\\=\sqrt(1)\\=1

Solve for the equation, show all your work. This is an absolute value equation. You need to show both equations and the work for

VMariaS [17]

Answer:

$x=-1$ or $7$

Step-by-step explanation:

We use casework on when $3x-9=12$ and when $3x-9=-12$ .

For the first case, $3x-9=12$ , we add 9 to both sides to get

$3x=21$ .

Dividing both sides by 3 gives

$x=7.$

For the second case, $3x-9=-12$ , we add 9 to both sides to get

$3x=-3$ .

Dividing both sides by 3 gives

$x=-1$ .

Checking both cases, we plug in $x=7$ and $x=-1$ .

For the first case, we have $|3(7)-9|=|21-9|=|12|=12$ , which satisfies the equation.

For the second case, we have $|3(-1)-9|=|-3-9|=|-12|=12$ , which also satisfies the equation.

This gives us two solutions to the equation; $x=7$ and $x=-1$ .

Find the surface area of the cylinder. Use 3.14 for pi . a hay bale with a diameter of 30 inches and a height of 72 inches about

valentina_108 [34]

Surface Area of cylinder = 8195.4 inches^2

Step-by-step explanation:

we are given:

Diameter of cylinder = 30 inches

Height of cylinder = 72 inches

We need to find:

Surface area of cylinder = ?

The formula used is:

$Surface\,\,Area=2\pi rh+2\pi r^2$

We know radius = diameter/2

so, radius = 30/2 = 15 inches

putting values:

$Surface\,\,Area=2\pi rh+2\pi r^2\\Surface\,\,Area=2*3.14*15*72+2*3.14*(15)^2\\Surface\,\,Area=6782.4+1413\\Surface\,\,Area=8195.4$

So, Surface Area of cylinder = 8195.4 inches^2
