Home values are expected to decreased by 3% per year. Hadlee Recently purchased a home for $200,000. Which of the following equations can be used to represent the value of the home x years after the purchase?
A) f(x) = 200000(1.03)^x
B) f(x) = 200000(0.97)^c
C) f(x) = 3(1.03)^x
D) f(x) =3(0.97)^x
Answer:
B
Step-by-step explanation
Multiplying by 0.97 will decrease $200,000 to $194,000.
^c is x years after the purchase, so having (0.97)^c will make the $200,000 value decrease more and more.

Energy sources that are non renewable include coal, natural gas, oil, and nuclear power.
What is Nonrenewable Resources?Since we currently rely on these resources to meet the majority of our energy needs, their exhaustion and inability to be replenished poses a serious issue for humanity.Human society depends on both nonrenewable and renewable resources for its everyday energy needs. Renewable resources can naturally replenish themselves, but nonrenewable resources cannot. This is the main distinction between these two types of resources. Due to their finite availability, nonrenewable resources cannot be used responsibly.Nuclear energy, coal, natural gas, and oil are the four main categories of nonrenewable resources. Fossil fuels refer to the three fuels that make up coal, natural gas, and oil. The name "fossil" comes from the fact that fossil fuels were created deep inside the Earth over the course of millions of years from decomposing plants and animals. They are discovered in the silt and rock layers below the earth's surface. Crude oil, also known as petroleum, coal, and natural gas were produced by the pressure and heat combined with the remains of plants and animals.The Complete Question is Nonrenewable Resources.

What is the minimum value of the function f x )= 16x 2 )- 16x 28?
The minimum value of the given function f(x) = 16x² −16x+28 is 24.
What are the Maxima and Minima of a Function?The curve of a function has peaks and troughs called maxima and minima. A function may have any number of maxima and minima. Calculus allows us to determine any function's maximum and lowest values without ever consulting the function's graph.
To find the minimum value of the function f(x) = 16x² −16x+28 using the derivative method, you can start by taking the derivative of the function. The derivative of a quadratic function is given by:
f'(x) = 2ax + b
In this case, the derivative of the function f(x) is:
f'(x) = 2×16x - 16
To find the minimum value, we need to find the x value that makes the derivative equal to zero. Setting the derivative equal to zero and solving for x gives us:
216x - 16 = 0
32x = 16
x = 0.5
Now that we have the value of x that minimizes the function, we can plug this value back into the original function to find the minimum value:
f(0.5) = 16×(0.5)² - 16(0.5) + 28 = 4 - 8 + 28 = 24
Therefore, the minimum value of the function is 24.

Median is the middle value of the set of data when the data is arranged in an ascending order.
The median of a data has a higher frequency if the data is distributed symmetrically.
We will arrange the given data in ascending order as 21, 23, 24, 25 and 27.
Also, the number of values here is 5, which is an odd number. As we know if the number of values is odd in a data, then the middle value will be the median.
For 5 numbers, the middle value will be the number from either side.
In the given data, as we can see that the value is 24, so 24 will be the median for the data.

What is the vertical asymptote of y 1x − 5?
The vertical asymptote of y = 1x - 5 is x = 5, since the denominator becomes zero when x = 5 and the function is undefined at this point.
The vertical asymptote of y = 1x - 5 is x = 5. This is because when x = 5, the denominator of the function (1x - 5) becomes zero, and the function is undefined at this point. As a result, the vertical asymptote is x = 5. This can be seen by taking the limit of the function as x approaches 5 from either side. As x approaches 5 from the left, the limit of the function is negative infinity, and as x approaches 5 from the right, the limit of the function is positive infinity. Thus, the vertical asymptote of y = 1x - 5 is x = 5, since the denominator becomes zero when x = 5 and the function is undefined at this point.

The weight of 2apple i 400 gram. I ate one apple of 150 gram. Find the weight of the other apple
The weight of the other apple is 250 grams.
As per the given data:
The weight of 2 apples is 400 gram.
The weight of 1 apple is 150 grams which I ate.
We have to determine the weight of the other apple.
Subtract the weight of 1 apple from weight of 2 apples
Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers
One value is 400 and the other value is 150.
Means subtract 150 from 400.
The weight of the other apple = Weight of 2 apples - The weight of 1 apple
= 400 - 150
= 250 grams
Therefore the answer is 250 grams.

What is linear angles?
If the angles follow the intersection of the two lines in a straight line, they are said to be linear. A linear pair's total angles are always equal to 180°. These are also referred to as supplementary angles. Angles that share a vertex are said to be adjacent.
Given: m ∠RXU = 52°
We have to find the measure of angle m ∠SXU.
Let RS and VW are two lines intersects by a transversal TU.
∠3 and ∠4 are adjacent to each other after the intersection of the two lines.
Since the sum of angles of a linear pair is always equal to 180°.
⇒ ∠3 + ∠4 = 180°
52° + ∠4 = 180°
∠4 = 180° - 52°
∠4 = 128°
Hence, the measure of angle SXU is m ∠SXU = 128°.

She completed one training day in a triathlon- 62.5 km.
Convert meter to kilometer :
1 kilometer = 1000 meter
⇒ 1 meter = [tex]\frac{1}{1000}[/tex] kilometer
On a training day, she swam = 1500 meter
= [tex]\frac{1500}{1000}[/tex] kilometer
= 1.5 kilometer
She rode a bike = 47000 meter
= [tex]\frac{47000}{1000}[/tex] kilometer
= 47 kilometer
She ran = 14 km
We may get the total distance by adding the distances she covered with swimming, riding, and running.
∴ Total distance she covered for a triathlon = ( 1.5 + 47 +14) km
