Please help me, I really need help. I will mark brainliest answer!! A bald eagle can eat 3.85 kilograms of fish in a week. The eagle eats the same amount each day. How many grams of fish will the eagle eat in a day?

Answers

So, let's list the facts:
1) In a week, the eagle eats 3.85 kilograms
2) there are 7 days in a week
3) on each day, the eagle eats the same amount.
This means that in order to find out how much was eaten on each day, we need to divide the whole week's food by the number of days in a week:

3.85/7= 0.55

(3.85=3.5+0.35 and 5*7=55, so (3.5+0.35)/7=0.5+0.05=0.55

Every day the eagle eats 0.55 kilograms of meat!

Which polynomial function has a leading coefficient of 2, root -4 with multiplicity 3, and root 10 with multiplicity 1?O f(x) = 2(x-4)(x-4)(x - 4)(x + 10)

O fx) = 2(x + 4)(« + 4)(« + 4)(-10)

O f) =3K – 4)(«-4)0x + 10)

O f()= 3(x + 4)(x + 4)(K- 10)

Answers

Answer:

f(x) = 2(x+4)(x+4)(x+4)(x-10)

Step-by-step explanation:

Here, we want to write a polynomial function with leading coefficient of 2, root - 4 with multiplicity 3 ( meaning it appears 3 times);

and root 10 with multiplicity 1

If x = -4

Then in linear form, we have x + 4

if x = 10, in linear form, we have x -10

So the polynomial is;

f(x) = 2(x+4)(x+4)(x+4)(x-10)
