C. we multiply the equation by 3
Answer:
23.9 m
Step-by-step explanation:
The hypotenuse of a right triangle inscribed in a circle is a diameter of the circle. Using Pythagorean theorem:
c² = a² + b²
c² = 3² + 7²
c = √58
The circumference of the circle is pi times the diameter.
C = π√58
C ≈ 23.9
Answer:
e^2 -7 = x
Step-by-step explanation:
2=ln(x+7)
Raise each side to the base of e
e^2 = e^ln (x+7)
The e^ln cancel
e^2 = x+7
Subtract 7 from each side
e^2 -7 = x +7-7
e^2 -7 = x
