Answer:
f(x) = 8(1/2)^x.
Step-by-step explanation:
According to the graph, there is a point at (0, 8) and (1, 4).
That means that when x = 0, y = 8.
8 = a(b)^0
1a = 8
a = 8
That means that a = 8, and when x = 1, y = 4.
4 = 8(b)^1
4 = 8b
8b = 4
b = 4/8
b = 1/2
So, f(x) = 8(1/2)^x.
Hope this helps!
It is given that a 4 in. x 5 in. picture is used to make a wall banner that is 48 in. x 60 in. Thus, we can see a small picture has been enlarged or expanded. Therefore, this is an expansion. Thus the complete answer will be:
A 4 in. x 5 in. picture is used to make a wall banner that is 48 in. x 60 in. This is an example of an Expansion.
Therefore, out of the given options, Option A is the correct option.
-47 is the absolute value
This statement is not true, you cannot add denominators if they are not the same
the correct answer is 8/15
brainliest answer please =)
I'll do part (a) to get you started.
The angle 'a' pairs up with the 123 degree angle as a corresponding angle pair. Due to the parallel lines, the corresponding angles are congruent. Therefore a = 123.
We also see that b = 123 as well since a = b (they are vertical angles).
Notice how angle c is adjacent to the 123 degree angle. These two angles form a straight line, so they must add to 180 degrees.
c+123 = 180
c = 180-123
c = 57
-------------------------
To summarize, we have these three angles
a = 123
b = 123
c = 57
