Answer:
the one real zero is in the interval (-1, 0)
Step-by-step explanation:
Descartes' rule of signs tells you there are 0 or 2 positive real zeros. Changing the signs of the odd-degree terms and applying that rule again tells you there is one negative real zero. At the same time, those coefficients (-3, -5, -5, +7) have a negative sum, so you know ...
f(-1) = -6
f(0) = +7
so there is a zero in the interval (-1, 0).
__
You can try a few values between x=0 and x=10 to see what the function does in that part of the graph. You find ...
f(1) = 10
f(2) = 21
f(3) = 58
So, it is safe to conclude that there are no real zeros for x > 0.
The only real zero of f(x) is in the interval (-1, 0).

Answer:
154.34%
Step-by-step explanation:
We are asked to determine what percentage of 357 is 551.
Let us assume that x% of 357 is 551.
So,
⇒
⇒
......... (1)
⇒ x = 154.34%
So, it is clear from the step (1) that when we take the basic ratio then multiply with 100, then we will get the percentage. (Answer)
