Answer:
$3419.46
Step-by-step explanation:
First we need to find the volume of the cone using the formula for a cone.
h = height = 60 in
r = radius = 11 in
V = (hπr²)/3
V = (60*3.14*11²)/3
V = (60*3.14*121)/3
V = 22796.4/3
V = 7598.8
The volume of the cone is 7598.8 in³.
Now, we need to find the cost of the metal by multiplying the number of cubic inches we need by the cost per cubic inch.
cost = .45 * 7598.8
cost = 3419.46
The cost for the steel of the sculpture would be $3419.46
The actual answer is 28,350
The average rate of change of the function, over the given interval is 2.
This question is incomplete, the complete question is:
What is the average rate of change of f(x) = 2x+10, if this function interval are x = -3 to x = 0.
<h3>What is the average rate of change over the interval?</h3>
The average rate of change of f(x) over the interval [a,b] is expressed as;
Given that;
- f(x) = 2x + 10
- Interval: [ -3, 0 ], a = -3 and b = 0
We substitute our values into the expression above.
![\frac{f(b)-f(a)}{b-a}\\\\\frac{f(0)-f(-3)}{0-(-3)}\\\\\frac{[2(0)+10]-[2(-3)+10]}{0-(-3)}\\\\\frac{[10]-[-6+10]}{3}\\\\\frac{[10]-[4]}{3}=\frac{6}{3}=2](https://tex.z-dn.net/?f=%5Cfrac%7Bf%28b%29-f%28a%29%7D%7Bb-a%7D%5C%5C%5C%5C%5Cfrac%7Bf%280%29-f%28-3%29%7D%7B0-%28-3%29%7D%5C%5C%5C%5C%5Cfrac%7B%5B2%280%29%2B10%5D-%5B2%28-3%29%2B10%5D%7D%7B0-%28-3%29%7D%5C%5C%5C%5C%5Cfrac%7B%5B10%5D-%5B-6%2B10%5D%7D%7B3%7D%5C%5C%5C%5C%5Cfrac%7B%5B10%5D-%5B4%5D%7D%7B3%7D%3D%5Cfrac%7B6%7D%7B3%7D%3D2)
Therefore, the average rate of change of the function, over the given interval is 2.

7x^2 - x = 6
7x^2 - x - 6 = 0
(7x + 6 )(x - 1) = 0
7x + 6 = 0; x = -6/7
x - 1 = 0; x = 1
answer
x = -6/7; x = 1
Start with putting the dot on the right to positive 5 on the y-axis (the vertical line) then from there use rise over run method. since it is negative you will move the dot on the left down instead. you will go DOWN 1 and to the LEFT 3. i’m sorry if i’m wrong:(((
