1
Step-by-step explanation:
When you take the log of ...
b = b^1
you get ...

That would be true because the adjacent side to B is 4 and the hypotenuse is 5 and the formula for cos b is adjacent/hypotenuse

34 feet + 18 feet = 52 feet
The oak tree is 52 feet tall.
x² = -7x + 4
x² + 7x - 4 = 0
x = -7 ± √(7² - 4(1)(-4))
2(1)
x = -7 ± √(49 + 16)
2
x = -7 ± √(65)
2
x ≈ -7 ± 8.06
2
x ≈ -3.5 ± 4.03
x ≈ -3.5 + 4.03 or x ≈ -3.5 - 4.03
x ≈ 0.53 or x ≈ -7.53
