Answer:
Total cost= $141.75
Step-by-step explanation:
Giving the following information:
Bernie's Bargains 6 DVDs for $56.70
Greg's Giveaways 10 DVDs for $99.70
Stan's Steals 8 DVDs for $79.68
<u>First, we need to determine the unitary price of each and choose the lowest one:</u>
Bernie= 56.7/6= $9.45
Greg= 99.7/10= $9.7
Stan= 79.68/8= $9.96
The lowest price is $9.45.
<u>Now, the total cost of 15 DVDs:</u>
Total cost= 9.45*15
Total cost= $141.75

Answer:
V = 4/3 pi r^3 for a sphere
Step-by-step explanation:
You can't a circle is a two dimensional object.
The volume of a sphere, which is the three dimensional form of a circle is found by
V = 4/3 pi r^3
Where r is the radius
Answer:
Inverse of f exists.
Step-by-step explanation:
From the graph attached,
If we do the horizontal line test for the function graphed,
We find the function as one to one function.
In other words for every input value (x-value) there is a different output value.
Since, for one-to-one functions, inverse of the functions exist.
Therefore, the answer will be,
The inverse of 'f' exists.
Easy peasy
just use PEMDAS and some exonential laws
also another is
![x^{\frac{m}{n}}=\sqrt[n]{x^{m}}](https://tex.z-dn.net/?f=%20x%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D%3D%5Csqrt%5Bn%5D%7Bx%5E%7Bm%7D%7D%20)
so
![[3(2a)^{\frac{3}{2}}]^{2}](https://tex.z-dn.net/?f=%20%5B3%282a%29%5E%7B%5Cfrac%7B3%7D%7B2%7D%7D%5D%5E%7B2%7D%20)
