4^x is an exponential function with base 4 and exponent x; its graph is entirely above the horizontal axis, and the curve representing 4^x continues to rise as x increases. Its y-intercept is (0,4^0), or (0,1).
Answer:
81
Step-by-step explanation:
9 × 3n= 3^7
9×3n= 2187
27n= 2187
n= 2187/27
= 81
Hence n= 81
Answer:
Option c. integers from 1 to 10 inclusive.
Step-by-step explanation:
The given sets are A = { 1, 3, 5, 7, 9 }
B = { 2, 4, 6, 8, 10 }
C = { 1, 5, 6, 7, 9 }
We have to determine A ∪ B
A ∪ B = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }
Therefore, A ∪ B is the set of all from 1 to 10 inclusive.
option C will be the answer.
