Which statement is true about the given function? f(x) > 0 over the interval (–infinity, 3).
f(x) > 0 over the interval (–infinity, infinity).
f(x) < 0 over the interval (–infinity, 3).
f(x) < 0 over the interval (–infinity, infinity).

From (-infinity to -2.7) it has negative values of y, that is less than 0 because it's down the x-axis.

From (-1 to 0.08) it also has negative values of y, that is less than 0.

Therefore, correct option is option B). f(x) < 0 over the intervals (-infinity, -2.7) and (-1 ,0.8).

Step-by-step explanation:

Answer is C

Step-by-step explanation:

Just answered it and got it right

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
