What 2 numbers can be added to make 16 as well as multiplied to make -36
Sladkaya [172]

Answer:

18 and -2

Step-by-step explanation:

Let x = 1st no.

y = 2nd no.

(1)    x + y = 16            (2)     xy = -36

           y = 16 - x                 x(16 - x) = -36

                                           16x - x^{2} = -36\\x^{2}  - 16x - 36 = 0\\

                                           (x - 18)(x + 2) = 0

                                               x = 18   or x = -2

          y = 16 - 18 = -2

         y = 16 -(- 2) = 16 + 2 - 18

The two numbers are 18 and -2

Find the ratio of the trig function
ohaa [14]

Answer:

cotΘ = \frac{3}{4}

Step-by-step explanation:

Using the trigonometric identity

cot x = \frac{1}{tanx}, then

tanΘ = \frac{opposite}{adjacent} = \frac{4}{3}, hence

cotΘ = \frac{1}{\frac{4}{3} } = \frac{3}{4}
