1600 with a 6% interest rate
The simple interest on 1600 with a 6% interest rate for 2 years is $192.
What is the simple interest?The simple interest simply means the method that's used to calculate the interest that's charged on a loan or money given out.
In this situation, we want to calculate the simple interest on 1600 with a 6% interest rate for 2 years. This will be calculated thus:
Simple interest = Principal × Rate × Interest
Simple interest = $1600 × 6% × 2
Simple interest = $1600 × 0.06 × 2
Simple interest = $192
The interest is $192.

A. slope of PQ = y2 - y1 / x2 - x1 = -1 - (-2)/1-5 = -1/4
B. Slope of QR = y2 - y1 / x2 - x1 = 7 - (-1) / 3 - 1 = 8/2 =4
C. Slope of PQ = y2 - y1 / x2 - x1 = 1 - 5 / -1 - (-2) = -4/1 = -4
D. slope of QR = y2 - y1 / x2 - x1 = 3 - 1 / 7 - (-1) = 2/8 = 1/4
The solution that correctly shows the slope calculation to enable Dorothy show that △PQR is a right triangle
C. Slope of PQ = (y₂ - y₁) / (x₂ - x₁) = (1 - 5) / (-1 - (-2)) = -4/1 = -4D. slope of QR = (y₂ - y₁) / (x₂ - x₁) = (3 - 1) / (7 - (-1)) = 2/8 = 1/4How to find slope of a lineRight triangles are triangles with have perpendicular relationships
The lines will be checked for perpendicularity by calculating the slopes, if any two slopes are negative reciprocals then they are perpendicular and the triangle is a right triangle
Using point PQ
m = (y₂ - y₁) / (x₂ - x₁)
m = (1 - 5) / (-1 - -2)
m = -4
Using point QR
m = (y₂ - y₁) / (x₂ - x₁)
m = (3 - 1) / (7 - -1)
m = 2/8 = 1/4
Comparing the slopes shows that slopes calculated are negative reciprocals
-4 and 1/4
Therefore the triangle is a right triangle

What's the domain of f(x)=log(5x+10)+3?
The domain of a function is the set of all possible input values that the function can take without breaking. In the case of f(x) = log(5x+10) + 3, the domain is all real numbers x such that 5x+10 is greater than 0. This is because the log function is not defined for values less than or equal to 0.
To find the domain of f(x), we need to solve the inequality 5x+10 > 0. We can do this by subtracting 10 from both sides of the inequality, which gives us 5x > -10. Dividing both sides by 5 gives us x > -2. Therefore, the domain of f(x) = log(5x+10) + 3 is all real numbers x such that x > -2.

A fish descends 4 meters per minute for 2 minutes. Then it ascends 3 meters per minute for 3 minutes. What is the total distance, in meters, the fish traveled?
The fish's total distance traveled is 17 meters in 5 minutes based on multiplication and addition operations.
How is the total distance traveled determined?The total distance the fish traveled can be determined using mathematical operations, especially multiplication and addition.
We know that distance is the product of speed and time, i.e. d = st, where s is speed, t is time, and d is distance.
In this situation, we separately find the distance the fish traveled during its descent and ascent by multiplying time and speed.
The results are added to obtain the total distance the fish traveled for both activities.
The fish's descent speed = 4 meters per minute (MPM)
The total time for the descent = 2
The total distance for the descent = 8 miles (4 x 2)
The fish's ascent speed = 3 meters per minute (MPM)
The total time during ascent = 3 minutes
The total distance for the ascent = 9 miles (3 x 3)
The total distance the fish traveled for descent and ascent = 17 meters (8 + 9)
Thus, we can mathematically conclude that the fish traveled 17 meters.

Which expression is equivalent to square root 36/25 ? 6/25, 5/6
Answer: 6/25
Step-by-step explanation: To find the equivalent expression, we can use the property of square roots that says that the square root of the quotient of two numbers is the quotient of the square roots of the numbers. This property is given by the following equation: sqrt(a/b) = sqrt(a) / sqrt(b)
In this case, the expression we are trying to simplify is sqrt(36/25), which we can rewrite using the property of square roots as follows: sqrt(36/25) = sqrt(36) / sqrt(25)
Then, we can use the property of square roots that says that the square root of a perfect square is the number itself to simplify the expression as follows: sqrt(36/25) = 6 / sqrt(25)
Finally, we can use the property of square roots that says that the square root of a perfect square is the number itself to simplify the expression even further: sqrt(36/25) = 6 / 5
Therefore, the equivalent expression to sqrt(36/25) is 6/25. This means that the correct answer is 6/25, not 5/6.

Write the domain as an inequality. Write the range as an inequality
The Domain and Range are −2 ≤ x ≤ ∞ & 0 ≤ y ≤ ∞ respectively.
What are the Domain and Range?
Graphs can be used as another tool for determining the domain and range of functions. The domain of a graph is made up of all the input values displayed on the x-axis since the term "domain" refers to the set of potential input values. The y-axis on a graph represents the possible output values or range.
Domain:
The x-value at the farthest left point is at x = −2. Now continue tracing the graph until you get to the point that is the farthest to the right. The x-value at this point is at ∞. There are no breaks in the graph going from left to right which means it’s continuous from -2 to ∞.
Domain: [-2, ∞][−2, ∞] also written as −2 ≤ x ≤ ∞
Range:
Look at the furthest point down on the graph or the bottom of the graph. The y-value at this point is y=0. Now, look at how far up the graph goes or the top of the graph. This is when x = ∞, but now we’re finding the range so we need to look at the yy-value of this point which is at y = 0. There are no breaks in the graph going from down to up which means it’s continuous.
Range: [0, ∞][0, ∞] also written as 0 ≤ y ≤ ∞.
Hence, the Domain and Range are −2 ≤ x ≤ ∞ & 0 ≤ y ≤ ∞ respectively.
