ANALYZE PROBLEMS The midpoints of the sides of a triangle are located at (a, 0),(2 a, b) and (a, b). If one vertex is located at the origin, what are the
coordinates of the other vertices?
,( ______0) and (______,______)
Answers
The coordinates of the other vertices of the triangle are (2a, 0), (2a, b), and (a, b).
What are the coordinates of the vertices of the triangle?
The coordinates of the vertices of a triangle are (x1,y1), (x2,y2), and (x3,y3). The line joining the first two is divided in the ratio l:k and the line joining this point of division to the opposite angular point is then divided in the ratio m:k+l.
To find the coordinates of the other vertices of the triangle, you can use the fact that the midpoint of a line segment is located at the average of the coordinates of the endpoints of the segment.
If the midpoint of one side of the triangle is located at (a, 0), then the coordinates of the two endpoints of this side must be (a, 0) and (2a, 0). The coordinates of one of the vertices is (2a, 0), and since this vertex is not the one located at the origin, the coordinates of the other vertex must be the origin, or (0, 0).
If the midpoint of another side of the triangle is located at (2a, b), then the coordinates of the two endpoints of this side must be (2a, b) and (2a, 0). One of the endpoints is (2a, 0), which we already know is a vertex of the triangle. The other endpoint, (2a, b), is also a vertex of the triangle.
Finally, if the midpoint of the third side of the triangle is located at (a, b), then the coordinates of the two endpoints of this side must be (a, b) and (0, 0). One of the endpoints is (0, 0), which we already know is a vertex of the triangle. The other endpoint, (a, b), is also a vertex of the triangle.
Hence, the coordinates of the other vertices of the triangle are (2a, 0), (2a, b), and (a, b).

What is Compound Interest?
Compound interest is interest based on the initial principle plus all prior periods' accumulated interest. The power of compound interest is the ability to generate "interest on interest." Interest can be added at any time, from continuously to daily to annually.
The formula for calculating Compound Interest is
A = P ( 1 + r/n )ⁿᵇ
where A = Final Amount
P = Principal
r = rate of interest
n = number of times interest is applied
b = number of time periods elapsed
When compounded continuously , the Compound Interest Amount is calculated by the formula ,
A = Pe^rt
Given data ,
Let the investment be P
The value of P = $ 1100
The rate of interest r = 5 %
The number of years t = 7 years
The Compound Interest Amount when compounded continuously is calculated by the formula ,
A = Pe^rt
Substituting the values in the equation , we get
A = 1100 x e ^ 0.05 x 7
A = 1100 x e ^ 0.35
A = 1100 x 2.718 ^ 0.35
A = 1100 x 1.419067
A = $ 1560.97
Therefore , the value of the amount is A = $ 1560.97
Hence ,

To convert Celsius temperatures to Fahrenheit temperatures, the function F defined by F(x) = 32 + 1.87 is useful. Confirm this, then find a formula for the function C (which could also be called F-1) that converts Fahrenheit temperatures to Celsius temperatures.
Answers
Answer: The function F(x) = 32 + 1.87x converts Celsius temperatures to Fahrenheit temperatures. To confirm this, you can plug in a few different values for x (the Celsius temperature) and see if the corresponding value of F(x) (the Fahrenheit temperature) is correct.
For example, if x = 0, the function gives us F(0) = 32 + 1.87 * 0 = 32, which is the correct conversion from Celsius to Fahrenheit for 0 degrees Celsius.
If you want to find a formula for the function C that converts Fahrenheit temperatures to Celsius temperatures, you can start by rearranging the formula for F(x). The Fahrenheit temperature is equal to the Celsius temperature plus 32, multiplied by 1.8.
If we solve for the Celsius temperature, we get:
x = (F - 32) / 1.8
This is the formula for the function C that converts Fahrenheit temperatures to Celsius temperatures. To use this function, you would plug the Fahrenheit temperature into the function as the input, and it will give you the corresponding Celsius temperature as the output.
For example, if you want to convert 100 degrees Fahrenheit to Celsius, you would plug 100 into the function as the input:
C(100) = (100 - 32) / 1.8 = 37.78 degrees Celsius.

no; y does not vary directly with x.
Answers
The ratio y/x is not constant (k) for all the data points, then y does not vary directly with x.
What is the constant of variation?
The constant of variation is the number that relates two variables that are directly proportional or inversely proportional to one another.
We have,
x y
2 10
4 24
6 36
To determine whether y varies directly with x, you need to see if the ratio of y to x is constant for all the data points.
If y varies directly with x, then the ratio y/x will be constant for all the data points. In this case, you can write an equation for the direct variation in the form y = kx, where k is the constant of variation, which is equal to the ratio y/x.
If the ratio y/x is not constant for all the data points, then y does not vary directly with x.
so, let's see the k constant of variation,
k = y/x
k = 2/10 =1/5
k = 4/24 = 1/6
k = 6/36 = 1/6
so, k = 1/5, k=1/6, k=1/6.
Hence, the ratio y/x is not constant (k) for all the data points, then y does not vary directly with x.

In which direction does the parabola defined by the equation y = -x + 2 open?
Answers
Answer:
Downward
Step-by-step explanation:
A parabola is a curve that is shaped like a U. The direction in which a parabola opens depends on the sign of the coefficient of the x^2 term in the equation defining the parabola. If the coefficient is positive, the parabola opens upwards. If the coefficient is negative, the parabola opens downward.
In the equation y = -x + 2, the coefficient of the x^2 term is 0, so the direction of the parabola does not depend on it. However, the coefficient of the x term is -1, which is negative. This means that the parabola defined by this equation opens downward.
During a fireworks display, a shell is shot into the air with a velocity of 58 m/s, its height in meters after t seconds is given by y=58t-20t^2
Find velocity when t=0.5
Answers
The velocity of a shell shot into the air with a velocity of 58 m/s, its height in meters after t seconds is given by y=58t - 20t² is 38 m / s.
What is velocity?When anything is moving, its velocity tells us how quickly that something's location is changing from a certain vantage point and as measured by a particular unit of time.
If a point moves along a path and covers a certain distance in a predetermined amount of time, its average speed over that period of time is equal to the distance covered divided by the travel time. A train traveling 100 kilometers in two hours, for instance, is doing it at an average speed of 50 km/h.
Given:
Height equation, y = 58t - 20t²,
The time, t = 0.5 seconds,
The initial velocity, u = 58 m/s,
Calculate the height at 0.5 sec,
y = 58 × 0.5 - 20 × 0.5²
y = 24 m
Calculate the acceleration at 0.5 sec by using the motion equation given below:
[tex]s = ut+1/2at^2[/tex]
24 = 58 × 0.5 + 1 / 2 × a × 0.5²
-5 = 0.125 × a
a = - 40 m / s²
Calculate the velocity by using the formula given below,
[tex]v = u + at[/tex]
v = 58 + (-40) × 0.5
v = 38 m /s
Therefore, the velocity of a shell shot into the air with a velocity of 58 m/s, its height in meters after t seconds is given by y = 58t - 20t² is 38 m / s.

Find f(0)
Find f(x) = -3
Answers
The set of all x for which the f(x) graph crosses the x-axis is the solution of f(x) = 0. The set of all x for which the graph of f is strictly above the x-axis is the solution of f(x) > 0
What is function notation?A simple and clear approach to write functions is in function notation. When we use function notation, the independent variable (often x) and the dependent variable (often F) for a function are both listed (x).A function provides an output after receiving an input. When writing a function, the name of the function is written as f (x) f(x) f(x)f, left parenthesis, x, right parenthesis, f, x is the input variable, and f (x) f(x) f(x)f, left parenthesis, x, right parenthesis, f is the output.a set of symbols that are used to represent unique objects. Example: "" stands for "infinity" in mathematical notation. Numerous symbols are used in mathematics.Given data :
f(0) =
The set of all x for which the graph of f is strictly above the x-axis is the solution of f(x) > 0
f (x) = -3
x = − 3 is a vertical line that crosses the -axis at -3. y = 3 is a horizontal line that crosses the -axis at 3. y = − 3 is a horizontal line that crosses the -axis at -3.
