A barn silo, excluding the top, is a cylinder. The silo is 7 m in
Elenna [48]

The volume of the silo is 461.81 m³

Step-by-step explanation:

A barn silo, excluding the top, is a cylinder

  • The silo is 7 m in  diameter
  • Its height is 12 m

We need to find the volume of the silo

∵ The silo is shaped a cylinder

∵ The volume of a cylinder = base area × height

∵ The base is shaped a circle

∵ Area a circle = π r², where r is the radius of the circle

∴ The volume of the silo = π r² × h

∵ The diameter of the silo = 7 m

∵ The radius of a circle is half the diameter

∴ The radius of the silo = \frac{1}{2} × 7 = 3.5 m

∵ The height of the silo = 12 m

- Substitute the values of r and h in the rule of volume

∴ The volume of the silo = π (3.5)² × 12

∴ The volume of the silo = 147 π = 461.81 m³

The volume of the silo is 461.81 m³

The table of values represents the function ​​ g(x) and the graph shows the function ​f(x)​.
Tanya [424]

Answer:

B, C

Step-by-step explanation:

x-intercepts are when y=0.  f(x) has two x-intercepts at (1, 0) and (5, 0).  g(x) also has two x-intercepts; (-3, 0) and (5, 0).  So the first one is false, and the second one is true.

The maximum value of f(x) is 2.  The maximum value of g(x) is 4.  So the third one is true.

The y-intercept is the value of y when x=0.  So the y-intercept of f(x) is -1, and the y-intercept of g(x) is 3.  So the fourth one is false.

A parabola can be represented by the equation y2 = –x. What are the coordinates of the focus and the equation of the directrix?
shutvik [7]

ANSWER

Focus:

(- \frac{1}{4} ,0)

Directrix:

x=\frac{1}{4}

EXPLANATION

The given parabola has equation:

{y}^{2}  =  - x

We compare this to the general equation,

{y}^{2}  =  - 4px

Comparing the coefficient of x, we have:

-4p=-1

p =  \frac{1}{4}

The focus is (-p,0)

(- \frac{1}{4} ,0)

The equation of the directrix is

x=p

x =  \frac{1}{4}

Please helppppppppppp me so the problem its jessica said that the sum of −8+d is always positive when the value of d is greater
Alex_Xolod [135]
<h3>Answer: Sometimes true</h3>

========================================================

Explanation:

-8+d is positive only when d > 8

Here's why

-8+d > 0

-8+d+8 > 0+8 .... add 8 to both sides

d > 8

So if Jessica said "d is greater than 8", then her claim would always be correct.

However, her claim is sometimes true.

Two counter examples could be when d = 1 and d = 2.

If d = 1, then -8+d = -8+1 = -7 which isn't positive.

If d = 2, then -8+d = -8+2 = -6 which also isn't positive.

Basically if d is anything smaller than 8, then you'll have -8+d be negative.

If d is something larger than 8, say d = 9, then -8+d = -8+9 = 1 which is finally positive.
