graph of function f of x equals 30 multiplied by 0.88 to the power of x
Step-by-step explanation:
The deodorant is begun to evaporate in other words, it is losing mass so the rate of 12% is a decay rate. In the exponential decay, the graph of the function goes according to the formula:
Where is the initial amount (
),
is the rate of decay (
) and
the times intervals, in this case, measured in days. Substituting the values in the formula:
Which corresponds with the "graph of function f of x equals 30 multiplied by 0.88 to the power of x".
Answer:
There are 26 purple marbles in the bag.
Step-by-step explanation:
Firstly, you have to make an expression in terms of x where x represent red marbles. Given that the question says purple marbles is 2 more than 3 times the number of red marbles. So the expression is :
Let red marbles = x,
Next, given that the total marbles in the bag is 34 so you have to add both marbles together and solve the value of x :
Lastly, you have to substitute the value of x into the expression of purple marbles :
Let x = 8,
