Answer:
b = - 0.432
Step-by-step explanation:
It takes 200 seconds to produce the first widget. And by the 400th widget, it takes only 15 seconds.
Now, the formula that gives the time to make the nth widget is given by
and we have to evaluate the constant b from the above-given conditions.
So, 
⇒ 
Taking log on both sides
b log (400) = log (0.075)
⇒ b = - 0.432 (Answer)

1 qt=2pt
4 qt=8pt=1 gal
if 1 gal 8pt
0,625 gal ? pt
?=0,625×8
?=5
<span>3^2 + 4^2 = 5^2
answer is </span>A) 3^2 + 4^2 = 5^2
Basically anything greater than zero...k>0
Option a is more steeper
The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept form formula is used to find the equation of a line when given the slope of the straight line and the y-intercept( the y-coordinate of the point where the line intersects the y-axis).
According to the slope intercept form of equation
y = mx + c
where m = slope of the line
c = y-intercept
the steeping of the graph is determined by the slope of the line on the graph. The more is the value of the slope the more steeper the graph will be of the given line.
In option a: m=3 whereas option b: m=1/2
So y=3x+7 is more steeper
