Answer:
x = 6
Step-by-step explanation:
Please write this as y = x^2 - 12x + 7 to indicate the exponentiation.
The coefficients of these three terms are a, b and c: 1, -12 and 7.
The equation of the axis (line) of symmetry is
-b -(-12)
x = --------- = ----------- = 6
2a 2(1)
Answer:
2.7w -14.04
Step-by-step explanation:
2.7(w-5.2)
Distribute the 2.7
2.7w -2.7*5.2
2.7w -14.04
Using the Law of Sines (sinA/a=sinB/b=sinC/c) and the fact that all triangles have a sum of 180° for their angles.
The third angle is C is 180-53-17=110°
27/sin53=b/sin17=c/sin110
b=27sin17/sin53, c=27sin110/sin53
And the perimeter is a+b+c so
p=27+27sin17/sin53+27sin110/sin53 units
p≈68.65 units (to nearest hundredth of a unit)
