F(x)=3(4)^x is an exponential function. Hence, this equation will increase by the exponent of x.
Let's make a table of values and look for the pattern:
x------f(x)
0 3 (zero power rule: 4^0 = 1)
1 12
2 48
3 192
So, let's look at the output values. From 3 to 12 (times 4), from 12 to 48, (times 4), from 48 to 192 (times 4).
So, the best answer is C. The number quadrupled each week.

Answer:
The sets could be 5, 5, 5, 5, 5 and 0, 10, 20, -10, 5
Step-by-step explanation:
Standard deviations are a measure of how far the average point is away from the mean. In the first example, each term is exactly the mean. In the second set, some are quite a distance from the mean and therefore, it would have a bigger standard deviation.
Answer:
D. Both x and y are variables
Step-by-step explanation:
2x+3y = 19
Both x and y are variables, since they are both unknown quantities
Answer:
x = 6
Step-by-step explanation:
Ratio between the top and bottom of the adult's chair is 7/14, or 1/2
So that means, x is equal to 12 x 1/2, or 6.
