Answer:
Answer:
Domain = {x /x ≥ -7}
Step-by-step explanation:
The given function y =
Inside the square, negative will not come.
First let's find the domain. x + 7 must be greater than or equal to 0.
x + 7 ≥ 0
Solving x, we get
x ≥ -7
Domain = {x /x ≥ -7}
Hope this will help you.
Answer:
12 Scoops
Step-by-step explanation:
Darla has 4 Cylinder Shaped Buckets
Volume of the Cylinders 
The scoop is cone shaped and:
Volume of the Cone Scoop 
Since the radius and height of the cone scoop and cylindrical buckets are the same,
The number of Cone Scoops it will take to fill the buckets is:
Total Volume of Buckets/Volume of Cone Scoops

It will take 12 Scoops to fill the 4 buckets.
Answer:
You are taking away 4 each time
Step-by-step explanation:
25 - 4 = 21
21 - 4 = 17
17 - 4 = 13
13 - 4 = 9
I'm assuming that there is another root which should be -SQRT(11)
f(x) = x(x-4)(x+SQRT(11))(x-SQRT(11)
Then
f(x) = x^4 -4x^3 - 11x^2 +44x
First off you need to take the square root of both sides and it leaves you with (x)(2x)= 15 then you multiple the x and it gives you 2x^2=15 then you divide by 2 and it gives you 7.5 then you take the square root of that to cancel the x^2 and it gives you x=2.7
