a man invested a total of $3,000 in two investments. he made a profit of 3% on the first investment and 4% on the second investment. if his total profit was $107, what was the amount of each investment?

Answers

Let the first investment be x
and second be 3000-x

so 3%of x + 4% of (3000-x) = 107
By solving x = 1300

First investment is 1300
second investment is 1700

Why is it necessary to apply inverse operations on both sides of the equals l sign when solving an equations

Answers

Take this example (cause it's easy to explain)

10+5x=15x

To solve it we have to minus five on both side. We have to do this because we need to isolate the variable (in this case x) on the one side so we can divide and solve.

You would -5x (inverse from positive 5) from both sides on this because whatever you do to one side you have to do to the others to make it equal. In this case the answer would be x=1 (again cause it's easy lol.)

I hope this helps you!

A radio tower is located on a coordinate system measured in miles. The range of a signal in a particular direction is modeled by a quadratic function where the boundary of the signal starts at the vertex at (4, 2). It passes through the point (5, 4). A linear road connects points (–3, 7) and (8, 2). Which system of equations can be used to determine whether the road intersects the boundary of the tower’s signal?

Answers

Given that the range of the signal is a quadratic function: (x-h)^2 = 4a (y - k) (5-4)^2 = 4a (4 - 2) 4a =1/2 therefore, (x -4)^2 = (1/2)(y – 2) The road is a line. Slope of the road is (7 -2)/(-3 -8) =-5/11 Therefore the equation of the line: 5x + 11y = 5(8) + 11(2) 5x + 11y = 62

The system of equations can be used to determine whether the road intersects the boundary of the tower’s signal; y = 2( x - 4 )² + 2 and 5 x + 11 y = 62.

What is the vertex form of a quadratic equation?

If a quadratic equation is written in the form

y = a(x-h)^2 + k

then it is called to be in vertex form.

It is called so because when you plot this equation's graph, you will see the vertex point is on (h,k).

To determine a quadratic function in vertex form:

y = a ( x - 4 )² + 2

4 = a ( 5 - 4 )² + 2

4 = a + 2

a = 2

y = 2 ( x - 4 )² + 2

Then we will determine a linear function in standard form, that passes through the points ( -3, 7 ) and ( 8, 2 ).

7 = -3 m + b

2 = 8 m + b / ·(-1)

7 = - 3 m + b

- 2 = - 8 m - b

5 = - 11 m

m = -5/11,

2 = -5/11 · 8 + b,

b= 2 + 40/11,

b = 62/11

Substitue,

y = - 5/11 x + 62/11 / ·11

11 y = - 5 x + 62

5 x + 11 y = 62

Finally the system of equations is:

y = 2( x - 4 )² + 2

5 x + 11 y = 62

If grade point average rises as number of hours watching tv falls, the correlation between GPA and TV is

Answers

If the grade point average (GPA) rises as the number of hours spent watching TV falls, the correlation between GPA and TV is likely negative or inversely correlated. This means that as one variable (TV watching) decreases, the other variable (GPA) tends to increase. Negative correlation is represented by a negative correlation coefficient, typically ranging from -1 (perfect negative correlation) to 0 (no correlation). In this case, the correlation coefficient would be less than 0 but greater than -1.

What are the domain and range of the function {(5, 3), (7, 1), (11, –2), (4, 9), (–2, 4)}? A.

B.
Domain: {5, 7, 11, 4, }; Range: {3, 1, 9, 4}

C.
Domain: {5, 7, 11, 4, –2}; Range: {3, 1, –2, 9, 4}

D.

Domain: {3, 1, –2, 9, 4}; Range: {5, 7, 11, 4, –2}

Answers

Answer is C. Set of first part of the binary set is domain and second part of it is range. So the domain will be {5, 7, 11, 4, –2} and the range will be {3, 1, –2, 9, 4}

Answer:

Domain: {5, 7, 11, 4, –2}; Range: {3, 1, –2, 9, 4}

Step-by-step explanation:

The domain is the X value or the independent in put.

Range is the Y values, or the Dependant input.
