See below

Step-by-step explanation:

The roots are:

3, 3, 2 - 3i, 2 + 3i (conjugate of 2 - 3i should be added) and the leading coefficient is - 5

The polynomial is:

-5(x - 3)² (x - [2 - 3i]) (x - [2 + 3i]) =
- 5(x² - 6x + 9) (x² - 4x + 13) =
-5(x⁴ - 10x³ + 46x² - 114x + 117) =
-5x⁴ + 50x³ - 230x² + 570x - 585

Arlecino [84]

Answer:

Step-by-step explanation:

Given the information from the question:

$fg - f = f \times g - f$

Next we can use the order of operations to find the value of the expression.

$fg - f = - 6 \times - 1 - ( - 1) \\ = 6 - ( - 1) \\ = 6 + 1 \\ = 7$

Please help me with this homework

snow_lady [41]

Answer:

10.44 m

Step-by-step explanation:

Solve this as a triange. The base is 3m and the perpendicular is 10m. The angle between the base and wall is 90° so it will be a right angled triangle.

Solve this by Pythagoras theorm:

let length of ladder is c

base is b

And perpendicular is a

Acc to Pythagoras theorem:

C² = a² + b²

C² = 10² + 3²

C² = 100 + 9

C² = 109

√C² = √109

C = 10.44m
