Answer:
Step-by-step explanation:
The cost (in dollars) in making b bracelets is represented is
The cost (in dollars) of making b necklaces is
To find how much more it will cost to make b necklaces than b bracelets, we find the difference,
This is a polynomial in descending powers of b, hence it is in standard form;
That's the answer for how is confidence levels determined
Answer:
Step-by-step explanation:f(h(x))= 2x -21
f(x)= x^3 - 6
h(x)=\sqrt[3]{2x-15}
WE need to find f(h(x)), use composition of functions
Plug in h(x)
f(h(x))=f(\sqrt[3]{2x-15})
Now we plug in f(x) in f(x)
f(h(x))=f(\sqrt[3]{2x-15})=(\sqrt[3]{2x-15})^3 - 6
cube and cube root will get cancelled
f(h(x))= 2x-15 -6= 2 x-21
Answer:
∠P = 39º
∠Q=120º
∠R = 21º
Step-by-step explanation:
m∠P+m∠Q+m∠R=180º (sum of ∠s in a triangle)
2x-3+6x-6+x=180º (substitution)
9x-9=180º (algebra)
9x=189º (algebra)
x=21º (algebra) (this is ∠R)
(2x-3)=39º (algebra) (this is ∠P)
6x-6=120º (algebra) (this is ∠Q)
The hundred-thousandth place is where the x is _x_,___.
You can round a number by taking the number to the right of it and seeing if it's over 5. If it is, you can make the number one higher, if not, then the number stays the same.
867,000 rounded to the nearest hundred-thousandth is 860,000.
