Answer:
D
Step-by-step explanation:
To determine if a function is exponential decay or growth, simply look at the rate. If the rate is less than one, it is decay. It it's greater than one, it's growth.
The rate in the given function is 0.75 or 75%. 0.75 is less than one so it's exponential decay.
To determine the percent decrease, simply subtract the rate into 1 or 100%. Thus:
Therefore, it is a 0.25 or 25% decrease.
The answer is D.
The ratio of the volume of the cylindrical tank to its surface area will be r / 2.
<h3>What is a cylinder?</h3>
A cylinder is a closed solid that has two parallel circular bases connected by a curved surface.
Let r be the radius and h be the height of the cylinder.
Then the volume of the cylinder will be
V = π r²h cubic units
Then the surface area of the cylinder will be
SA = 2πrh square units
Then the ratio of the volume of the cylindrical tank to its surface area will be
V / SA = π r²h / 2πrh
V / SA = r / 2
The ratio of the volume of the cylindrical tank to its surface area will be r / 2.

We need to write the expression <span>3(x + y) = 2y - x in a verbal sentence. We do as follows:
Three times the sum of x and y is equal to two times y minus x.
or
The sum of x and y multiplied by three is equal to the difference of two y and x.
or
Three quantity x plus y is equal to the product of two and y minus x.
or
Three multiplied by the sum of x and y is equal to two times y minus x.
Either of the statements I have written above would be correct and would mean the same equation.</span>
