Answer:

The length of AB is 7.45 units.

Step-by-step explanation:

You can find the length of AB using Cosine Rule, cosθ = adj./hypo. :

θ = 20°

adj. = 7 units

hypo. = AB

cos 20° = 7/AB

AB = 7/cos 20°

= 7.45 units (3s.f)

The domain of the given absolute value function is (-∞, ∞) .

This means the function is defined for all real values of x.

The range of the function is (-∞, 0].

This can be rewritten as

$y \leqslant 0$

This means that, the highest y-value on the gray of this absolute value function is 0.

Hence the maximum y-value of the function is 0.

Hatshy [7]

Answer:

False

Step-by-step explanation:

6/12 simplifies into 1/2 (six is half of twelve) and 1/2 does not equal 1/3.

You can also plug this into a calculator and see that 6/12=0.5 and 1/3=0.333

F(x) = 4x² + 5x - 3<br> g(x) = 4x³<br> 3x² + 5<br> Find (f+g)(x).

Dmitriy789 [7]

Answer:

$4x^3+7x^2+5x+2$

Step-by-step explanation:

Given:

$f(x)=4x^2+5x-3$

$g(x)=4x^3+3x^2+5$

$\begin{aligned}\implies (f+g)(x)=f(x)+g(x) & = (4x^2+5x-3) + (4x^3+3x^2+5) \\& = 4x^2+5x-3+4x^3+3x^2+5 \\& = 4x^3+4x^2+3x^2+5x-3+5 \\& = 4x^3+7x^2+5x+2 \\\end{aligned}$
