B (t) = 50 (1.4) ^ t
What is the y-intercept of the function?
The intersection with the y-axis of the function you find when x = 0.
In this case we have:
For t = 0:
B (0) = 50 (1.4) ^ 0
B (0) = 50 * (1)
B (0) = 50
Answer:
the y-intercept of the function is:
B (0) = 50
What does this mean in the context of the problem?
You must place the complete statement to answer exactly.
However, in any problem of exponential type, it means the initial quantity of something.
If we refer to the increase in population over time, then the intersection with the y-axis is the initial population.
Answer:
a=40. b=140. c= 40
Step-by-step explanation:
b is congruent To 140 because of the vertical angles postulate that states two angles vertical from one another are congruent.
a is 40 because it is Supplementary to b Which means that the sum of a and b must add up to 180.
c is Congruent to a due to the vertical angles postulate
Answer: Choice D
(0,-4) (4,0) and (-1,-5)
===========================================================
Explanation:
Plug in x = -4
y = x-4
y = -4-4
y = -8
The point (-4,-8) is on the line instead of (-4,0). This rules out choice A and choice B.
Now plug in x = 1
y = x-4
y = 1-4
y = -3
We get (1,-3) instead of (1,5). So we can rule out choice C.
The answer must be choice D.
The graph is below.
