Graph the function f(x) = 16(1.87)x. Does this function show growth or decay? What is the equation of the asymptote?
Growth; y = −16
Growth; y = 0
Decay; y = −16
Decay; y = 0
Growth; y = −16
Growth; y = 0
Decay; y = −16
Decay; y = 0
The function f(x) = 16(1.87)x shows growth. The equation of the asymptote is y = 0.
The same amount of trash is dumped into a landfill every day. The function below shows the total number of tons of trash n in the landfill after x days:
n = 2000x + 1000
What does the number 1,000 represent?
a. Amount of trash originally in the landfill
b. Amount of trash added to the landfill every day
c. Rate at which the total trash increases every day
d. Rate at which the new trash increases every day
n = 2000x + 1000
What does the number 1,000 represent?
a. Amount of trash originally in the landfill
b. Amount of trash added to the landfill every day
c. Rate at which the total trash increases every day
d. Rate at which the new trash increases every day
The number 1,000 represents the amount of trash originally in the landfill. Therefore, the correct answer is option a.
The function below represents the interest Larissa earns on an investment. Identify the term that represents the amount of money originally invested.
f(x) = 7,000(1 + 0.03)x
1
7,000
0.03
1.03
f(x) = 7,000(1 + 0.03)x
1
7,000
0.03
1.03
The term that represents the amount of money originally invested is 7,000.
Which of the following is a function equivalent to f(x) = 5(1.9)3x?
f(x) = 34.29x
f(x) = 5(6.86x)
f(x) = 5(6.86)x
f(x) = 328.51x
f(x) = 34.29x
f(x) = 5(6.86x)
f(x) = 5(6.86)x
f(x) = 328.51x
The function equivalent to f(x) = 5(1.9)3x is f(x) = 5(6.86)x.
And of course, the Bot missed the first one
√18 + √2 = 3√2 + √2 = 4√2
√18 + √2 = 3√2 + √2 = 4√2
I apologize for the mistake in my previous response. You are correct, the expression √18 + √2 simplifies to 3√2 + √2, which further simplifies to 4√2. Thank you for pointing out the error.
