Which equation is represented by the graph below ?
1 answer:
The equation that represent the graph is y = (1/2)eˣ , Option B is the correct answer.
<h3>What is an Exponential Function ?</h3>An exponential function is what is denoted as y = eˣ
The graph has to be studied and the equation has to be determined.
To determine we will consider x = 0 for all the equation ,. which will give the y intercept , which is below 1 so Option C and D are stroked out.
Now we plot the graph for equation A and B
It can be easily understood from the graph that at x =0 , y = 0.5
Therefore , the equation that represent the graph is
y = (1/2)eˣ
Option B is the correct answer.

Answer: The value of n = 7.
Step-by-step explanation:
Since we have given that
Number of beads is to selected = 20
Number of dozen each of n different colored beads = 2
Number of different colored beads = n
With repetitions of colors allowed.
Number of ways = 230,230
So, it becomes
now,
By hit and trial we get that
Hence, the value of n = 7.
Answer:
√205 +√178 +1 ≈ 28.6595
Step-by-step explanation:
The distance formula tells you the distance between points (x1, y1) and (x2, y2) is ...
d = √((x2 -x1)^2 +(y2-y1)^2)
Taken pairwise, the distances between the given points are ...
d1 = √((-10-4)^2 +(-4-(-7))^2) = √(196+9) = √205
d2 = √((3-(-10))^2 +(-7-(-4))^2) = √(169+9) = √178
d3 = √((4-3)^2 +(-7-(-7))^2) = √1 = 1
Then the sum of the distances gives the perimeter:
P = d1 +d2 +d3 = √205 +√178 +1 ≈ 28.6595
_____
In the attached figure, the distance "a" is the sum of the two long sides of the triangle.
