mary wants to fill in a cylinder vase. the flower store told her to fill the vase 4/5 of the way for the flowers to last the lon
Goshia [24]

Volume is a three-dimensional scalar quantity. The volume of the water that Marry should pour into the vase is 241.28 cubic inches.

<h3>What is volume?</h3>

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

Given the radius of the flower vase is 4 inches, while the height of the vase is 6 inches, therefore, the total volume of the vase is,

Volume = πR²×H = π× 4²×6 = 301.6 in³

Since the volume of the vase is 301.6 in³, but the store has told her to fill the vase 4/5 of its capacity, therefore, the volume of water Marry should pour is,

Volume of water = (4/5) × 301.6 in³ = 241.28 cubic inches

Hence, the volume of the water that Marry should pour into the vase is 241.28 cubic inches.

Write a quadratic equation to represent the circle graphed on the right
Ivahew [28]

Answer:

<h2>The standard form: x² + (y + 1)² = 25</h2><h2>The general form: x² + y² + 2y - 24 = 0</h2>

Step-by-step explanation:

The equation of a circle:

(x-h)^2+(y-k)^2=r^2

(h, k) - center

r - radius

We have the center (0, -1) and the radius r = 5   <em>(look at the picture)</em>.

Substitute:

(x-0)^2+(y-(-1))^2=5^2\\\\x^2+(y+1)^2=25

<em>use (a + b)² = a² + 2ab + b²</em>

x^2+y^2+2y+1=25             <em>subtract 25 from both sides</em>

x^2+y^2+2y-24=0

Donald Trump wants to build a 100 meter high tower as quickly as possible. He has unlimited resources and an unlimited budget an
Sladkaya [172]

It will take 100 weeks to build the tower.

Since Donald Trump wants to build a 100 meter high tower as quickly as possible with blocks that are 100 meters long and 100 meters wide, but only 1 meter tall, and using special lifters, putting one stack on top of another stack takes one week regardless of how high the stacks are, to determine what is the shortest amount of time (weeks) that it will take to build the tower, the following calculation must be performed:

  • Time per block x total blocks = Total time
  • 1 week x 100 = X
  • 100 weeks = X

Therefore, it will take 100 weeks to build the tower.

What is the function for a table with a domain of 5, 10, 15, 20 and a range of 40, 80, 120, and 160
kykrilka [37]
To find the range we need to find the vertex of the parabola which is at (-b/2a , y)

-b/2a would be 2/2 = 1 ... so find the y value at x = 1

12 - 2(1) - 15 = 1-17 = -16

So the vertex is at (1,-16)

Since the parabola opens upward from that point the minimum value of the range is y = -16

The range would include the point -16 so it is actually

R = [-16,infinity)
