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.

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 hours did it take to drive to Louisville-3.25 hours

The long is the scenic route from Louisville. 237miles

Jenny traveled to Louisville at 68 miles per hour

Let d is the distance travelled to Louisville and t is the time taken.

68= d/t

On the way back she took the scenic route and drove 56 miles per hour.

distance of way back= d+ 17

time taken=t+1

56=(d+17)/(t+1)

t=3.25 hours

d=221miles

Based on the bisection of line BC by point A, the value of x is 10/3

The given parameters are:

Because the point A bisects BC, then

BA = AC

Substitute the known values in the above equation

So, we have

6x - 3 = 3x + 7

Collect the like terms

6x - 3x = 3 + 7

Evaluate the like terms

3x = 10

Divide both sides of the equation by 3

x = 10/3

Hence, based on the bisection of line BC by point A, the value of x is 10/3

The coordinate of point P is (7/2, -13)

The formula for calculating the midpoint of coordinates is expressed as shown below:

M(x, y) = {(mx₁+nx₂)/2, (my₁+ny₂)/2}

Given the coordinate points A(-4, 2) and B(3, -6) divided in the ratio 2:5, then;

M(x, y) = {(2(-4)+5(3))/2, (2(2)+5(-6))/2}

M(x, y) = {-8+15)/2, (4-30)/2}

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

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

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.

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]
