Because logarithms were a lot less time-consuming than other methods of finding roots. They were also more accurate in the sense that it was harder to make a mistake.
Answer:
D
Step-by-step explanation:
3/5 = 0.6
75% = .75
0.8, 0.75, 0.6, 0.56
Discriminant = b^2 - 4ac; where a = 1, b = 9 and c = 14
d = (9)^2 - 4(1)(14)
d = 81 - 56
d = 25
the discriminant is greater than zero, so there are two real roots
I'm assuming we're solving for x.
One property of a straight line is that the angles that make a straight line have to add up to 180 degrees.
Given this information, we know that 4x + 5 + 41 = 180
4x + 46 = 180
4x = 134
x = 134/4 = 33.5
