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

Answer:

**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

**Answer:**

**This month the bakery used 300 kilograms of butter.**

**Step-by-step explanation:**

The amount of butter used last month = 240 kilograms

The amount of butter extra used this month = 25%

Now, 25 % of 240 kg =

= 60 kilograms

⇒**The extra butter used this month = 60 kg**

So,the __total butter used this month = 240 kg + 60 kg = 300 kilograms__

**Hence, this month the bakery used 300 kilograms of butter.**

A cone is a 3 D or 3 dimensional figure with no sides, and one point.

Can you please help me with this question.

This a proportion.

Lets solve by cross multiplying.

5/25 = 13/x

5 * x = 5x 13 * 25 = 325

325 = 5x

5x/5 = 325/5

x= 325/5 x= 65

**Answer: 5/25 = 13/65**

Lets solve by cross multiplying.

5/25 = 13/x

5 * x = 5x 13 * 25 = 325

325 = 5x

5x/5 = 325/5

x= 325/5 x= 65

5/25

This can be simplified to 1/5

1/5 = 13/?

In order to get to 13 from 1 you must multiply by 13

If we multiply the bottom (denominator) by 13 we get the missing value

5 x 13 = 65

5/25 = 13/65

This can be simplified to 1/5

1/5 = 13/?

In order to get to 13 from 1 you must multiply by 13

If we multiply the bottom (denominator) by 13 we get the missing value

5 x 13 = 65

5/25 = 13/65

X=35

3x+x=140

4x=140

X=35

3x+x=140

4x=140

X=35

If you take 2/5 minus 8/10 the final results would be -2/5 and it equals -0.4.

2/5 because 2/5 is 4/10. 8/10-4/10=4/10.4/10=2/5~JZ
