If the factors of a quadratic function are (x + 2) and (x − 9), what are the x-intercepts of the function? A.
(-9,0) and (-2,0)
B.
(-2,0) and (9,0)
C.
(2,0) and (9,0)
D.
(-9,0) and (2,0)

The x-intercepts of the function are:

(-2,0) and (9,0)

Step-by-step explanation:

As

so

Either

( x + 2 ) = 0

or  

( x - 9 ) = 0

solving ( x + 2 ) = 0

solving ( x - 9 ) = 0

We also know that to get x-intercepts by setting y=0.

Therefore, the x-intercepts of the function are:

(-2,0) and (9,0)

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
