Answer:
The degree of polynomial is 5.
Step-by-step explanation:
I suppose the polynomial is 
. To find the which degree this polynomial is, we consider the highest exponent of the term which is 
, the 5 is our highest degree of the term and thus, 5 is our highest degree of polynomial.
The domain of the inverse of a function is the range of the original function
so find the range of f(x)
this is lowest to highest
we got the vertex is at (0,4)
and it goes to infinity
so range is from 4 to infinity
inverse
replace f(x) with y
switch x and y
solve for y
replace y with finverse
f(x)=x^2+4
y=x^2+4
x=y^2+4
x-4=y^2
y=√(x-4)
f⁻¹(x)=√(x-4)
inverse is f⁻¹(x)=√(x-4)
the domain is x≥4
Answer: 31 cups
Step-by-step explanation:
We should note that 1 quarts = 4 cups
Therefore, 9 1/2 quarts = 9 1/2 × 4 = 19/2 × 4 = 38 cups
Since only 7 cups of tea remained.after the party, the number of cups of iced tea that the people drank during the party will be:
= 38 - 7
= 31 cups of iced tea
Answer: 25 oil changes
Step-by-step explanation:
75/ 3 =25
Answer:
√40 ≈ 6.32
√75 ≈ 8.66
√90 ≈ 9.49
√245 ≈ 15.65
√450 ≈ 21.21
√640 ≈ 25.30
√675 ≈ 25.98
Step-by-step explanation:
You can use your calc or estimate your answer by simplifying (like √640 is 8√10, and estimate the square root of 10). However, getting decimals will require you to use a calc.
