Answer:
<em>1 and 9</em>
Step-by-step explanation:
<u>Common Solutions to Functions</u>
Let f(x) and g(x) be any type of function. When we need to find values of x such that f(x)=g(x), we usually set up the equation for each of them and solve it for x by any available algebraic or approximate method.
In this situation, we are not given the explicit expression of any of the functions, but the table of values for each one of them. We have to take a look of the values of x for which f and g are the same.
A closer look at the table reveals that f(x)=g(x) for two values of x:
for x=1, f(1) = 14 , g(1) = 14
for x = 9, f(9) = 6, g(9) = 6
The answers are 1 and 9
Answer:
30
Step-by-step explanation:
Since the question says that it took her 45 minutes per hour, you can use that to find the distance of the route she took.
45 miles: 60 minutes
15 miles: 20 minutes ----------------cross multiply (20x45 and then divide by 60)
Therefore, if she is going to use the same route in reverse, the distance would be 15 miles.
Use the formula for speed:
speed= distance/time
= 15/0.5 ---------- 0.5 hours is the same as 30 minutes
= 30
Answer:
4.73%
Step-by-step explanation:
y = 3×2^(t/15) = 3×(2^(1/15))^t = 3×1.0472941^t
In this form, ...
1 +r = 1.0472941
r = .0472941 ≈ 4.73%
The daily increase is about 4.73%.
