1.	Find the zeroes of x square+2x_15
Answer» Answer: 3 and - 5 Step-by-step explanation: ${x}^{2} + 2x - 15$ FIRST FACTORIZE it. ${x}^{2} + 5x - 3x - 15$ $x(x + 5) - 3(x + 5)$ $(x - 3)(x + 5)$ So RHE zeroes are $x - 3 = 0 \\ x = 3$ And $x + 5 = 0 \\ x = - 5$

1.

Find the zeroes of x square+2x_15

Answer»

Answer:

3 and - 5

Step-by-step explanation:

${x}^{2} + 2x - 15$

FIRST FACTORIZE it.

${x}^{2} + 5x - 3x - 15$

$x(x + 5) - 3(x + 5)$

$(x - 3)(x + 5)$

So RHE zeroes are

$x - 3 = 0 \\ x = 3$

And

$x + 5 = 0 \\ x = - 5$

11.	Find the principal solution of sec x =2/√3
Answer» Step-by-step explanation: secx = 2 /√3 ☑ principal SOLUTION = The solution of trigonometric equation of an UNKNOWN angle angle 'x ' , where 0 < x < 2π , are called it's principal solution ☑ so we have, secx = 2/ √3 , we have to FIND its principal solution ,MEANS the values of angle x BELONGS to 0 < x < 2π secx = 2 /√3, secx = sec ( π / 6 ) , sec x = sec(2π - π/ 6 ) = sec(11π /6) therefor , 0 < π/6 < 2π and 0< 11π /6< 2π therefore, the principal solutions are x = π / 6 and x = 11π/6

11.

Find the principal solution of sec x =2/√3

Answer»

Step-by-step explanation:

secx = 2 /√3

☑ principal SOLUTION =

The solution of trigonometric equation of an UNKNOWN angle angle 'x ' , where 0 < x < 2π , are called it's principal solution

☑ so we have, secx = 2/ √3 , we have to FIND its principal solution ,MEANS the values of angle x BELONGS to

0 < x < 2π

secx = 2 /√3,

secx = sec ( π / 6 ) ,

sec x = sec(2π - π/ 6 ) = sec(11π /6)

therefor ,

0 < π/6 < 2π and 0< 11π /6< 2π

therefore, the principal solutions are

x = π / 6 and x = 11π/6

ANSWER:

Rain fall in 2002 = 54 CM

Step-by-step explanation:

The average rainfall over a GIVEN PLACE during the three-year period of 2003-2005 was 65 cm. During the three-year period 2002-2004 the average rainfall was 63 cm. The ACTUAL rainfall during 2005 was 60 cm

Average rainfall for 2003-2005 = 65 cm

Total rain fall for 2003-2005 = 65*3 = 195 cm

2005 = 60 cm

2003 & 2004 = 195 - 60 = 135 cm

Average rainfall for 2002-2004 = 63 cm

Total rain fall for 2002-2004 = 63*3 = 189 cm

2002 + 2003 & 2004 = 189

=> 2002 = 189 - 135

=> 2002 = 54 cm

Rain fall in 2002 = 54 cm
