Answer:
Step-by-step explanation:
12.5= 25/2
Ln (25/2).. change decimal to fraction
Ln ((5^2)/2)...change 25 to 5^2
(2ln 5)/2... log rule.. move exponent to the front
Ln 5 .. . Simplify the top and bottom 2's
<h3>
Answer: -8</h3>
===================================================
Work Shown:
Q(x) = 4x^2 + 5x - 7
Q(-1) = 4(-1)^2 + 5(-1) - 7 .... replace every x with -1; use PEMDAS
Q(-1) = 4(1) + 5(-1) - 7
Q(-1) = 4 - 5 - 7
Q(-1) = -1 - 7
Q(-1) = -8
Answer:
Step-by-step explanation:
Take a triangle ABC, in which AB=AC.
Construct AP bisector of angle A meeting BC at P.
In ∆ABP and ∆ACP
AP=AP[common]
AB=AC[given]
angle BAP=angle CAP[by construction]
Therefore, ∆ABP congurent ∆ACP[S.A.S]
This implies, angle ABP=angleACP[C.P.C.T]
