Answer:

C. y=3/2 x + 12

Step-by-step explanation:

lets find slope,

fr that first lets point out some coordinates passing the line: ( 0, 12 ), ( 2,15 )

now find slope using the equation : y -y1/ x - x1

= 15 - 12 / 2 -0 = 3/2

use any coordinates now to find the equation of line using formula:

y - y1 = m ( x - x1 )

y - 12 = 3/2 ( x - 0 )

y -12 = 3/2 x - 0

y = 3/2 x + 12

Therefore, y = 3/2 x + 12 is the equation of the line.

Answer:

C. 31.83 feet.

Step-by-step explanation:

We have been given that Trina has $1000 to purchase an open-top cylindrical dog pen in her backyard. She wants the height of the pen to be 5 feet.

First of all, we will find the surface area of dog pen using surface area of cylinder.

$\text{Surface area of cylinder}=2\pi rh$ ,where,

r = Radius of cylinder,

h = Height of cylinder.

$\text{Surface area of cylinder}=2\pi r*5$

$\text{Surface area of cylinder}=10\pi r$

Since the area of each square foot of pen costs $1, so in $1000 Trina can cover an area of 1000 square feet.

Now, we will set the surface area of cylinder equal to 1000 to solve for the radius.

$1000=10\pi r$

Upon dividing both sides of our equation by 10 pi we will get,

$\frac{1000}{10\pi}=\frac{10\pi r}{10\pi}$

$31.8309886=r$

$r\approx 31.83$

Therefore, the radius of the dog pen is 31.83 feet and option C is the correct choice.

Exact volume: Approximate volume:

slamgirl [31]

Answer: Multiplying these factors gives the approximate volume of the original body

Step-by-step explanation:

The given convex body can be approximated by a sequence of nested bodies, eventually reaching one of known volume (a hypersphere), with this approach used to estimate the factor by which the volume changes at each step of this sequence.
