A pharmacist put 2.415 ounces of vitamin pills into bottles. She put 0.023 ounces of vitaminpills into each bottle.
How many bottles did the pharmacist use for these vitamin pills?

Answer:

'There are 7 rocks in 4 boxes, How many rocks are there in total.'

Step-by-step explanation:

We are given to form a word problem having solution which has 4 as a factor.

Now, if we take the following statement,

'There are 7 rocks in 4 boxes, How many rocks are there in total.'

Its solution is given by,

As there are 4 boxes in total and each box has 7 rocks.

Thus, total number of rocks will be 4 × 7 = 28.

We can see that 4 is a factor of 28.

Hence, the word problem could be 'There are 7 rocks in 4 boxes, How many rocks are there in total.'

Answer:

Two complex roots.

Step-by-step explanation:

F(x)=2x^4 +5x^3 - x^2 +6x-1

is a polynomial in x of degree 4.

Hence F(x) has 4 roots.  There can be 0 or 2 or 4 complex roots to this polynomial since complex roots occur in conjugate pairs.

Use remainder theorem to find the roots of the polynomial.

F(0) = -1 and F(1) = 2+5-1+6-1 = 11>0

There is a change of sign in F from 0 to 1

Thus there is a real root between 0 and 1.

Similarly by trial and error let us find other real root.

F(-3) = -1 and F(-4) = 94

SInce there is a change of sign, from -4 to -3 there exists a real root between -3 and -4.

Other two roots are complex roots since no other place F changes its sign

y = -8 and x = -1 are the answers
