The answer:
by definition, an exponential function with base c is defined by <span>h (x) = ac^x</span><span>
where a ≠0, c > 0 , b ≠1, and x is any real number.</span>
The base, c, is a constant and the exponent, x<span>, is a variable.
</span>so if we have f(x)=3(3\8)^2x, this equivalent to f(x)=3(3\8)^y(x),
where y (x)=2x, <span>
therefore, the base is 3/8, and the variable is the function </span>y (x)=2x,
Answer:
14, 3, 5, 6.25, 10
Step-by-step explanation:
The scale is 1 inch = 0.5 ft.
Either divide the inches by 2 or multiply the feet by 2
Answer:
No, it does not represent a proportional relationship.
Step-by-step explanation:
The ratios do not reduce to the same value.
40/1 = 40
50/2 = 25
60/3 = 20
We can also tell straight away that this is not a proportional relationship because Nina starts with $30. If the data were graphed, this would mean that the line would not go through the origin. It would start at 30 on the y axis.
Answer:
No solution
Step-by-step explanation:
Me again. You can apply the same Theorems I posted on your other question, but ill give you a quick summary here. It isn't a triangle because of the Triangle Inequality Theorem (I go into depth with it on the other question).
, the LHS reduces to 0, so 
is a factor of the cubic. You can find the remaining two solutions easily with the quadratic formula.
