The cost of each stone sphere is $ 36.81
<em><u>Solution:</u></em>
Given that,
An architect plans to buy 5 stone spheres and 3 stone cylinders
For the same amount, she can buy 2 stone spheres and 6 stone cylinders
Let "x" be that same amount
Let "a" be the cost of each stone sphere
Cost of each stone cylinder = $ 36.81
Therefore,
x = 5 stone spheres and 3 stone cylinders
x = 5a + 3(36.81)
Similarly,
x = 2 stone spheres and 6 stone cylinders
x = 2a + 6(36.81)
Equate both,

Thus cost of each stone sphere is $ 36.81
Answer:
The graph in the attached figure
Step-by-step explanation:
we have

Obtain the function g(x)

substitute
![g(x)=-\frac{1}{5} [\left|x+3\right|-5]](https://tex.z-dn.net/?f=g%28x%29%3D-%5Cfrac%7B1%7D%7B5%7D%20%5B%5Cleft%7Cx%2B3%5Cright%7C-5%5D)

using a graphing tool
The graph in the attached figure
The vertex is the point (-3,1)
The x-intercepts are the points (-8,0) and (2,0)
The y-intercept is the point (0,0.4)

Answer: Whats the Question?
Step-by-step explanation:
Total investment = 12,000
Let x be invested in Stock at a return of 14%
The rest (12,000-x) invested at a loss of 6%
0.14*x - 0.06*(12,000-x) = 680
0.14x -720 +0.06x = 680
0.2x = 1400
x = 7000
So $7,000 was invested at a rate of 6% and $5,000 (12000-7000) was invested at a loss of 6%
