Answer:
x ≈ 65.4 °
Step-by-step explanation:
cos x = 
Cos x = 
Cos x = 0.4167
x = Cos⁻¹ (0.1467)
x ≈ 65.4 °
Answer:

Step-by-step explanation:
Instead, since the divisor is in the form of
, use what is called Synthetic Division. Remember, in this formula,
gives you the OPPOSITE terms of what they really are, so do not forget it. Anyway, here is how it is done:
4| 1 −5 7 −12
↓ 4 −4 12
_______________
1 −1 3 0 → 
You start by placing the
in the top left corner, then list all the coefficients of your dividend [x³ - 5x² + 7x - 12]. You bring down the original term closest to
then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have no remainder. Finally, your quotient is one degree less than your dividend, so that 1 in your quotient can be an
, the −1 [
] follows right behind it, and bringing up the rear, comes the 3, giving you the quotient of
.

ANSWER

EXPLANATION
The vertex of the graph is at

The equation of the graph in vertex form is given by the formula,

The above graph has a minimum point, hence

When we put these values into the equation we obtain,

This implies that,

The point (-2,0) lies on the line.
