Answer:
Domain of y=![\sqrt[4]{x-1}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7Bx-1%7D)
: is x>=1
Interval notation: [1,∞)
Step-by-step explanation:
We have y=
1) The domain of a function is the set of x values for which the function is real and defined.
2) So, x-1 should be positive means x-1>=0, because fourth root of any negative value would be a complex number and not a real number.
3) Now we solve the inequality x-1>=0
4) Adding 1 to both sides of the inequality we get,
x-1+1 > = 0+1
5) Cancel out -1 and +1 from the left side
6) We get x>=1
It concludes that for the domain of the given function, the x value must be greater than or equal to 1

Answer:
Part 1) The area of the structure is 
Part 2) The slab will contain 
of cement
Step-by-step explanation:
Part 1) Find the area of the structure
we know that
The area of the structure is equal to the area of rectangle plus the area of semicircle
<u><em>Find the area of rectangle</em></u>
The area of rectangle is equal to
we have
substitute
<u><em>Find the area of semicircle</em></u>
The area of semicircle is
we have
substitute
<u><em>Find the area of the structure</em></u>
Adds the areas
Part 2) If the structure is 6 in thick, how many cubic feet of cement will the slab contain?
Remember that
Convert inches to feet
<u><em>Find the volume of the structure</em></u>
To obtain the volume , multiply the area by 0.5 ft (thick)
so
You have invested 1200 dollars in your mutual fund and now gained 1333 dollars. First let's solve how much money added to your investment.
=> 1333 - 1200 = 133 dollars was added to your account
=> 133 / 1200 = 0.11
Next, lets convert this to decimal value.
=> 0.11 * 100% = 11% was added to you investment.
