If a₀ , a₁ , a₂ , a₃ , are all positive , then 4a₀x³ + 3a₁x² + 2a₂x + a₃ = 0 has at least one root in (-1,0) if
artcher [175]
If f(x)=4a_0x^3+3a_1x^2+2a_2x+a_3, then you have

f(-1)=-4a_0+3a_1-2a_2+a_3
f(0)=a_3

By the intermediate value theorem, there will be some number -1 such that f(c)=0 (i.e. f(x) will have a root in (-1,0)) if you can guarantee that f(-1) or f(-1)>f(c)>f(0).

Since the coefficients a_i are all positive, then you know right away that f(0)>0, so you need to have f(-1) in order for there to be such a c.

This means you need to have

-4a_0+3a_1-2a_2+a_33a_1+a_3

which means (A) must be the answer.

Anyone know the answer to this?
kiruha [24]

Answer:

42

Step-by-step explanation:

Angle ABD = Angle CBD + Angle ABC

You know ABD is 70, CBD and ABC are in terms of x

70 = 5x + 13 + 3x + 33

70 - 13 - 33 = 8x

24 = 8x

3 = x

Replacing x in Angle ABC:

3 * 3 + 33 = 42
