A rational function can have infinitely many x-values at which it is not continuous. True or False. If false, explain

sattari [20]

<span>It is false since the rational function is discontinuous when the denominator is zero. But the denominator is a polynomial and a polynomial has only finitely many zeros. So the discontinuity points of a rational function is finite. </span>

In the accompanying diagram of circle O, chords AB and CD intersect at E and

RoseWind [281]

Answer:

m(arc AC) = 72°

m(arc BD) = 108°

m∠DEB = 90°

Step-by-step explanation:

Ratio of the measure of arc AC, arc BC, arc BD and arc AD = 4 : 2 : 6 : 8

Since, m(arc AC) + m(arc CB) + m(arc BD) + m(arc AD) = 360°

By the property of ratio,

Measure of arc AC = $\frac{4}{4+2+6+8}\times (360^0)$

= $\frac{4\times 360}{20}$

= 72°

Measure of arc BD = $\frac{6}{4+2+6+8}\times (360^0)$

= $\frac{6\times 360}{20}$

= 108°

Measure of ∠DEB = $\frac{1}{2}m(arcAC + arc BD)$

= $\frac{1}{2}(72+108)$

= 90°

Finger [1]

Answer:

Step-by-step explanation:

equation:

18x - 8 + 11x = 20x +19

Add like terms:

29x - 8 = 20x + 19

add 8 to both sides:

29x = 20x + 27

subtract 20x from btoh side:

9x = 27

Divide both sides by 9:

x = 3

substitute x into the equation for SU

SU = 20(3) + 19

Solve:

SU = 79
