A silo is in the shape of a cone. The silo is 7 meters tall, and its base has a radius of 1.5 meters. Rice costs 204$ per cubic
olganol [36]

Answer:

  $3364.65

Step-by-step explanation:

The volume of the cone is given by the formula ...

  V = (1/3)πr²h

Filling in the given numbers, we find the volume to be ...

  V = (1/3)π(1.5 m)²(7 m) = 5.25π m³ ≈ 16.49336 m³

The cost of the rice will be the product of this volume and the price per cubic meter:

  cost = (16.49336 m³)($204/m³) = $3364.65

The cost of the rice necessary to fill the volume is $3364.65.

_____

<em>Comment on pi</em>

If you use the value 3.14 for pi, the cost comes to $3362.94. A 3-digit value of pi only gives an answer good in its first 3 digits.

Which function does this graph correspond to?
tiny-mole [99]
ANSWER

The function that the given graph corresponds to is
f(x) = (x - 2)(x - 1)(x + 1)(x  + 2)



EXPLANATION

The given graph in the attachment has x-intercepts at

x =  - 2 ,x=-1,x=1  \:  \: and   \: \: x=2


These are the solutions of the polynomial function represented by the given graph.




We can write all these solutions as factors to obtain,

x  + 2  ,x + 1 ,x - 1   \:  \:and \:  \: x - 2


The product of all these factors gives us the function whose graph was drawn.


This implies that,

f(x) = (x - 2)(x - 1)(x + 1)(x  + 2)


Therefore the correct answer is option C.

Line SU intersects Line TV at point R. What is the value of x, in degrees?
umka2103 [35]

Answer: X is equal to 30

Step-by-step explanation: I found this by taking 75 + 15 which is 90 then dividing it by 3 so 30. This is correct because since the linear pair is equal to 75 degrees then this also needs to be 75 degrees and 3 x 30 = 90 and 90 - 15 = 75.

Hope this helps.
