A, B, and C are points of tangency. CQ = 5, PQ = 10, and PR = 14. What is the perimeter

igomit [66]

*see attachment for diagram

Answer:

Perimeter = 38

Step-by-step explanation:

Recall: when two tangents are drawn to meet at a point outside a circle, the segments of the two tangents are congruent.

Given,

CQ = 5

PQ = 10

PR = 14

Perimeter of ∆PQR = RC + CQ + QB + BP + PA + AR

CQ = QB = 5 (tangents drawn from an external point)

BP = PQ - QB

BP = 10 - 5 = 5

BP = PA = 5 (tangents drawn from an external point)

AR = PR - PA

AR = 14 - 5 = 9

AR = RC = 9 (tangents drawn from an external point)

✔️Perimeter of ∆PQR = RC + CQ + QB + BP + PA + AR

= 9 + 5 + 5 + 5 + 5 + 9

Perimeter = 38

98 POINTS!!! Write a polynomial function in standard form given the zeros ±√5 , 7

Neporo4naja [7]

Answer:

Step-by-step explanation:

Knowing the three zeros of the equation, we can set it up as follows:

$(x - \sqrt{5})(x + \sqrt{5})(x - 7)$

Multipying the first two expressions together gives us the following:

$(x^{2} - 5)(x - 7)$

Multiplying the two expressions together gives us the following:

$x^{3} - 7x^{2} - 5x + 35$
