The value of b is 4
Step-by-step explanation:
The form of an exponential function is 
, where
- a is the initial value (value f(x) at x = 0
- b is the growth/decay factor
- T find the values of a and b substitute x and f(x) by the coordinates of any points belong to the function
∵ 
∵ The function includes the points (2 , 16) , (3 , 64) , (4 , 256)
- To find b substitute x and f(x) by the coordinates if any point above
∵ x = 2 and f(x) = 16
∴ 
- Take √ for both sides
∴ ± 4 = b
Substitute x by 3 and f(x) 64 to check your answer
∵ 
- Take ∛ for both sides
∴ 4 = b
∴ The value of b is 4 only
The value of b is 4

Answer:
B. Miami is 93 degrees warmer than Anchorage.
Step-by-step explanation:
Miami-Anchorage is equal to 65-(-28) which is equal to 65+28 which is equal to 93. Thus, Miami is warmer by 93 degrees.
<em>Hello there, and thank you for posting your question here on brainly.
</em>Short answer: x = -5
<em>
</em>Why?
The solution to this has a lot of steps. Subtract two from both sides. (2+7/x=3/5 --> 7/x=-7/5) Multiply both sides by x. (7/x=-7/5 --> 7=-7x/5) Multiply both sides by 5. (7=-7x/5 --> 35=-7x) Divide both sides by -7. (-5=x) x = -5
