Answer:
NO
Step-by-step explanation:
Look at the figure attached below, we know that the area of the cone is the sum of area of circle part and cone part of the figure.
to find the surface area of the cone, first measure the radius of the base and find the area of the circle part by formula 
. Then measure the side (slant height) length of the cone part and find the area of the cone part by the formula 
.
Now the surface area of the cone is circumference of the circle plus area of the cone part.
i.e. 
From the above discussion we concluded that surface area of the cone does not depend only on the circumference of the base but also we need side length of the cone part as well thus <em>all cones with a base circumference of 8 inches will </em><em>not </em><em>have the same surface area.</em>

Answer:
Option D: 0.3069
Step-by-step explanation:
Formula for coefficient of variation on the company's stock is;
CV = σ/E(r)
Where σ is the standard deviation and E(r) is expected value of return.
From the attached image, we can find E(r) as;
E(r) = 0.45(25) + 0.5(15) + 0.05(5)
E(r) = 19%
From online calculation, the standard deviation is 5.83%
Thus;
CV = 5.831/19
CV ≈ 0.3069
Answer: 6
Step-by-step explanation:
7 - 3 = 4
3 - 4 = 0
0 - 6 = -6
Pythagorean theorem a squared + b squared= c squared
The answer is D) 12 ft, no it does not reach.
The correct question is
<span>Teresa graphs the following 3 equations: y=2x, y=x2+2, and y=2x2. She says that the graph of y=2x will eventually surpass both of the other graphs. Is Teresa correct? Why or why not?
we have that
y=2x
y=x</span>²+2
y=2x²
using a graph tool
see the attached figure
<span>We can affirm the following
</span>the three graphs present the same domain-----> the interval (-∞,∞)
The range of the graph y=2x is the interval (-∞,∞)
The range of the graphs y=x²+2 and y=2x² is the interval [0,∞)
therefore
<span>Teresa is not correct because the graph of y = 2x will not surpass the other two graphs since in the interval of [0, infinite) the three graphs present the same range</span>
