Answer:
y=0 when x=-1
Step-by-step explanation:
We look at the chart to see that there is a value for y when x equals negative 1.
According to the chart, y equals 0 when x=-1.
Therefore, the answer is 0.
The pattern is multiplying by 3. So it will be: 243, 729
Answer:
Step-by-step explanation:
A person invested $2,500 in an account growing at a rate allowing the money to double every 11 years. How long, to the nearest tenth of a year would it take for the
value of the account to reach $3,800?
The formula for exponential growth given as:
A(t) = Ao (1/2)^t/t½
A(t) = Amount after time t = $3,800
Ao = Initial amount invested = $2500
t = Time in years
t½ = Time it takes to double = 11 years
Hence,
3800 = 2500(1/2)^t/11
Divide both sides by 2500
3800/2500 = 2500(1/2)^t/11/2500
Answer:
Approximately 10.2 inches
Step-by-step explanation:
The area of a square is given by the formula:

Where A is the area and s is the side length.
Since we already know that the area A is 105, substitute:

Now, take the square root of both sides:

Use a calculator:

So, the side length is approximately 10.2 inches.
