Answer: 2  

Reason:  

2x^3 - 11x^2 + 12x + 9  

= 2x^2(x-3) - 5x(x-3) -3(x-3)  

= (x-3)(2x^2 - 5x - 3)  

= (x-3)^2 (2x + 1)

If sin θ = 2 over 7 and tan θ > 0, what is the value of cos θ?
sergey [27]
Sin θ = 2 / 7
tan θ > 0
cos θ = ?

sin θ = opposite / hypotenuse
tan θ = opposite / adjacent
cos θ = adjacent / hypotenuse

short leg = opposite = 2
hypotenuse = 7
long leg = adjacent = ?

adjacent = √(7² - 2²)
adjacent = √(49 - 4)
adjacent = √45
adjacent = √9 * 5
adjacent = 3 √5

cos θ = adjacent / hypotenuse
cos θ = 3√5 / 7

Three sevenths of a children's choir are boys. If there are 12 boys in the choir, how many children, c, total are in the choir?
ruslelena [56]

Answer:

Here c represents the total number of children  in choir.

As per the statement:

Total number of boys in choir = 12

It is also given that: Three sevenths of a children's choir are boys.

⇒ Total number of boys = \frac{3}{7} c

or

12 = \frac{3}{7}c

By cross multiply we have;

84 = 3c

Divide both sides by 3 we have;

c = 28

Therefore, the total number of children in choir is 28 children

Answer:

31 degrees

Step-by-step explanation:

well each three point of a triangle equals 180

so 20+35= 55   180-55= 125

now if the exterior angle is 156 and it should equal 180 the interior angle would be 24 degrees

now we have 24 and 125 so angle ? = 31
