Zoe wants to make a driveway.
-Dominant- [34]
Well the volume of dirt she needs to remove is equal to length*width*height=6.2*4.9*0.225=6.8355

Now let's find how many bags she needs.

To solve for this, simply divide room in bags from total room.
6.8355/0.87=7.857

Thus Zoe has barely enough, but enough bags.

HELP PLEASE!!! <br>the question and answer are in the image attached​

Answer:

g(x)=\sqrt[3]{x-3}+4

Step-by-step explanation:

The function g(x) is a shifted version of the function f(x); f(x) is shifted by 3 along x-axis and by 4 along y-axis.

Another way of thinking about this is that the function g(x) contains points (3, 4); therefore,

g(x)=\sqrt[3]{x-3}+4

which goes through the point (3, 4).
