Answer:
Yes, the given table represent an exponential function.
Step-by-step explanation:
Given table is :
x y
1 4
2 16
3 64
4 256
Now we need to identify if the given table represent an exponential function or not. To find that we need to check if we can write the numbers in y-column in form of exponential function
.
We see that y-values are basically powers of 4 so we can write the related function as
.
Which is clearly in form of
.
Hence yes, the given table represent an exponential function.
For this you need to use the reverse cosine function
Cos^-1 (.25)
75.6
The area is 11.61 square feet and the perimeter is 14 feet. i hope this helps :)
Area=Length times width
Perimeter=Length+Length+width+width
Ok what am I supposed to answer?
Answer:
-9x
Step-by-step explanation:
-7x + -2x
Factor out the x
x(-7-2)
x(-9)
-9x
