The position of the stadium, given the data is 60 Km east and 10 Km south

Speed is the distance travelled per unit. Mathematically, it can be expressed as:

Speed = distance / time

With above formula, we can determine the position of the stadium. Details below

Speed = distance / time

Cross multiply

Distance = speed × time

Distance = 120 × 1/2

Distance = 60 Km east

Speed = distance / time

Cross multiply

Distance = speed × time

Distance = 60 × 1/6

Distance = 10 Km south

Thus, we can conclude that the position of the stadium is 60 Km east and 10 Km south

Answer:

(-2 , 0)

Step-by-step explanation:

The solution to this system of equations is the x and y values where the two lines cross.  That is where x is -2 and y is 0.  You can check/verify by putting these x and y values into the original equations.

The random variable x, which represents the number of defective cameras in the sample, is x = 0, 1, 2

A random variable is a variable with an unknown value or a function that gives values to each outcome of an experiment. A random variable might be discrete (with discrete values) or continuous (with continuous values) (any value in a continuous range).

The box contains two malfunctioning cameras.

The random variable, x, represents the sample space for the number of malfunctioning cameras that can be chosen;

The outcomes are:

Both cameras are faulty; x = 2

One is flawed, one is not; x = 1

Both cameras are in good working order; x = 0

This defines that the random variable , x = 0, 1, 2

The random variable x, which represents the number of defective cameras in the sample, is  x = 0, 1, 2

Answer:

[tex]f(x)=-|x-3|+7[/tex]

Step-by-step explanation:

The parent function of an absolute function is the modulus function:

[tex]f(x)=|x|[/tex]

Graph of Modulus function:

(see 2nd attachment)

[tex]f(x)=|x|=\begin{cases} \textsf{\:\:\:$x$, \quad if $x\geq 0$}\\\textsf{$-x$, \quad if $ x < 0$} \end{cases}[/tex]

Its vertex is at the origin (0, 0).

Its line of symmetry is x = 0.

It opens upwards.

Given information:

The axis of symmetry is the x-value of the vertex of an absolute function. 

The y-value of the range is the y-value of the vertex of an absolute function.  

Therefore, the vertex of the absolute function f(x) is (3, 7).

Graphing

To find the equation of the absolute function, work out the series of transformations that take the parent function to the given function.

As the function f(x) has a range of (-∞, 7), it opens downwards.  Therefore, the parent function has been reflected in the x-axis:

[tex]\implies -f(x)=-|x|[/tex]

As the function f(x) is symmetric about the line x=3, the parent function has been translated 3 units to the right:

[tex]\implies -f(x-3)=-|x-3|[/tex]

Finally, as the highest y-value of the function is y = 7, the y-value of its vertex is y = 7.  Therefore, the parent function has been translated 7 units up:

[tex]\implies -f(x-3)+7=-|x-3|+7[/tex]

Therefore, the equation of the absolute function with the given parameters is:

[tex]f(x)=-|x-3|+7[/tex]

The time Emma should take for the run must be less than 15 minutes to bear her previous record.

Emma's previous record was 1 hour and 10 minutes. This is equivalent to

60+10 minutes equals 70 minutes.

She already has run 55 minutes;

So, let us consider the remaining time, x, added to 55, must be less than 70 to overcome her previous time:

x + 55 < 70

The inequality is obtained.

Subtract 55 from each side:

x + 55-5 < 70-55

x < 15

Therefore, the remaining time of the run by Emma must be less than 15 minutes to beat her previous record.

Radius of a quarter circle is 2  then area is the π

Area of quarter circle is [tex]= (A = \pi r^2/4)[/tex]

A circle is a locus (collection) of points that are a defined distance apart from one another. The fixed point and fixed distance are referred to as the "center" and "radius," respectively. A quarter-circle is one-quarter of a circle. As a result, the area of a quarter circle is one-fourth of the size of a full circle.

A quarter circle is the area (or part) created by two perpendicular radii and one-fourth of the circumference of a circle. This is also known as a circular quadrant. For example, if a circle is divided into four equal pieces, each half is a quarter circle (or) a quadrant.

Answer:

x² - 10x + 25

Step-by-step explanation:

The given information is,

→ f(x) = -x + 7

→ g(x) = x² - 4x + 4

The equation we form is,

→ (gof)(x)

→ g[f(x)]

→ f(x)² - 4f(x) + 4

Let's solve the problem,

→ f(x)² - 4f(x) + 4

→ (-x + 7)² - 4(-x + 7) + 4

→ x² - 14x + 49 + 4x - 28 + 4

→ x² - 10x + 25

Hence, answer is x² - 10x + 25.

n = 1 is a counterexample for both the given equations.

Here, we are given two equations, let us look at them one by one-

a. (n + 5) / 5 = n + 1

let us take n = 1

the, (1 + 5) / 5 = 1 + 1

6/ 5 = 2

This equation does not hold as 6/5 ≠ 2. Thus, n = 1 doesn't satisfy the given equation and hence is a counterexample.

b. (n + 4)² = n² + 4²

Let us take n = 1

(1 + 4)² = 1² + 4²

5² = 1 + 16

25 = 17

Again, this equation does not hold as 25 ≠ 17. Thus, n = 1 doesn't satisfy the given equation and hence is a counterexample.

The supplied statement indicates that the angle of elevation will be = -75 feet.

The term angle of elevation refers to the angle between the horizontal and an object. The line of sight of an observer would be over the horizontal. The term angle of depression refers to the angle between the horizontal and an item. The line of sight of an observer would fall below the horizontal.

"rise over run" is an easy-to-remember equation for calculating a change in elevation as a decimal, which means the rise (the change in vertical distance) divided by that of the run (the change in horizontal distance). As an example, suppose the increase is two and the run is six. So you'd multiply 2 by 6 (or 2/6) to get.
