Transforme em π rad :<br>a)30°<br>b)40°<br>c)45°<br>d) 50°

Roman55 [17]

Answers:

a) $\frac{1}{6} \pi rad$

b) $\frac{2}{9} \pi rad$

c) $\frac{1}{4} \pi rad$

d) $\frac{5}{18} \pi rad$

Step-by-step explanation:

In this case we are dealing with angles, which can be expressed in degrees ( $\°$ ) or radians ( $rad$ ).

Now, before making the conversions we have to know the equivalence between degrees and radians:

$180 \°=1 \pi rad$

Taking this information into account, let's begin with the answers:

a) $30\° \frac{1 \pi rad}{180 \°}=\frac{1}{6} \pi rad$

b) $40\° \frac{1 \pi rad}{180 \°}=\frac{2}{9} \pi rad$

c) $40\° \frac{1 \pi rad}{180 \°}=\frac{1}{4} \pi rad$

d) $50\° \frac{1 \pi rad}{180 \°}=\frac{5}{18} \pi rad$

Simplify the expression. What classification describes the resulting polynomial?

netineya [11]

Answer:

Step-by-step explanation:

Given

(3x² - 11x - 4) - (2x² - x - 6)

Distribute both parenthesis, noting the second is distributed by - 1

= 3x² - 11x - 4 - 2x² + x + 6 ← collect like terms

= x² - 10x + 2 ← this is a quadratic with 3 terms, thus trinomial → A
