Answer:
degree 4
Step-by-step explanation:
The degree of a polynomial is determined by the term with the largest exponent for the polynomial in standard form
Given
P(x) = (x - 1)(x + 2)(x + 3)(2x - 5)
We need only consider the product of the leading terms in each factor, that is
x(x)(x)(2x) = 2
← is the leading term in the expansion of the factors
with exponent 4
Thus polynomial is of degree 4
Answer:
40
Step-by-step explanation:
If we go by 20's (20% of 100) 100% is 5. Since were dealing with 120% in our case we'll be dividing by 6 <u>to figure out what every 20% is</u>. All we need to do it's divide 48 by 6 and we get the answer 8. So in our case every 20% is equal to 8. now to solve for 100% all we need to do is subtract 8 (20%) from 120% (48) and we find 100% is 40. We could also do 8 x 5. (<em>remember every 1 is 20% in our case</em>) which is also 40. Therefore, your answer is 40.

They are inverse functions though to be completely thorough your teacher should have also put g(f(x)) = x as well. Though I can see what your teacher is aiming for at least.
The idea is that whatever the output of g(x) is, it's plugged into f(x) and the initial input is the result. So g(x) takes a step forward and f(x) takes a step back undoing everything g(x) did. Which is exactly what an inverse operation does.
The filling rate is 2/5=0.4 gallons per second. So the appropriate equation is A.
