Using the numeric value of functions, it is found that the pole vaulter will run 50 feet farther in 2 seconds.

To find the numeric value of a function, we replace each instance of the variable by the desired value.

The formula for the velocity is given as;

v=8√h

where h is the height.

we have the height is of h = 9.8,

hence:

v = 8√(9.8) = 25 feet per second.

The holder was running at the rate of 25 feet per second.

Then, within two seconds, the distance is given as;

d = 25 x 2 = 50 feet.

Hence, The pole vaulter will run 50 feet farther in 2 seconds.

a) f is strictly increasing function then f is one to one

b) f: R-> R such that f(x) = x^n where n is even is not one to one

suppose that f is strictly increasing function

we have to prove that f is one to one

let us assume f(x1) = f(x2)

we have to prove x1=x2

since f is strictly increasing function

then x2>x1 and x1> x2

this implies that x1=x2

and Hence f is one to one function

b) f:R->R such that f(x) = x^ n where n is even is not one to one

because f(1)= f( -1)

but -1 is not equal to 1 therefore f is not one to one function

Answer:

Step-by-step explanation:

Let

y ----> total charge in a month

x ----> number of minutes

so

Plan A

y=0.21x+11

Plan B

y=0.10x+20

Equate both equations

0.21x+11=0.10x+20

solve for x

0.21x-0.10x=20-11

0.11x=9

x=9/0.11

x=81.82 minutes

Convert to hours and minutes

81.82 minutes=60+21.82=1 hour 22 min

The quadratic equation is [tex]9x^2-2/3x-\frac{1+2\sqrt{2}}{3}[/tex]

Quadratic Equation:

A quadratic function is a function of degree two.

The general form of the quadratic equation is as follows:

x² + (sum of roots)x + Product of roots.

Given,

Here we have the roots,

[tex]\frac{-1-\sqrt{2} }{3} ,\frac{-1+\sqrt{2} }{3}[/tex]

And the coefficient with x² is equal to 9.

Through the given details we have to find the quadratic equation.

To find the equation we have to identify the sum of roots and the product of roots.

So, the sum of roots is,

[tex]= > \frac{-1-\sqrt{2} }{3} +\frac{-1+\sqrt{2} }{3}[/tex]

[tex]= > \frac{-1 }{3} +\frac{-1 }{3}\\= > \frac{-2}{3}[/tex]

y = (x - 1)² - 10 is the vertex form of the equation y = x² - 2x - 9.

Given, y = x² - 2x - 9

The equation is already in standard form : y = ax² + bx + c

where a=1, b=-2 and c=-9 according to the equation y = x² - 2x - 9.

The vertex form of parabola is: y = a (x - h)² + k

The "a" in y = ax² + bx + c equation  and the "a" in equation y = a (x - h)² + k are the same attributes of a parabola, therefore, substitute 1 for "a" in equation y = a (x - h)² + k: y = (x - h)² + k.

"h" is the x coordinate of the axis of the vertex: h = [tex]\frac{-b}{2a}[/tex]

Substitute in the values: h = - ( -2 ) ÷ 2(1)

∴ h = 1

Then, Substitute the value of h into the y = (x - h)² + k.

y = (x - 1)² + k.

Using the coordinates x and y from the above equations,

k = 1² - 2(1) - 9

k = 10

Now, Substitute the value of k into the equation y = (x - 1)² + k.

y = (x - 1)² - 10.

We need to know about fraction to solve this problem. The amount Reshma spent on comic books is Rs 165 and the amount that is left with her is Rs 495.

We can solve this problem by calculating what 1/4th of 660 will be. In this question we know that Reshma spends 1/4th of her pocket money on comic books out of Rs 660. We can think of 660 being divided in 4 parts equally and that Reshma spends one part of it. The amount that will be left with Reshma is the rest three parts.

Reshma spends= 1/4x660=165

Amount left= 660-165=495

Therefore the amount Reshma spends on comic books is Rs 165 and the amount that is left with her is Rs 495.

A graph of the linear equation (3x + 2y = 6) in standard form is shown in the image attached below.

A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.

In Mathematics, the graph of any proportional relationship such as a linear equation is characterized by a straight line as shown in the image attached below.

Next, we would rewrite the linear equation in standard form as follows:

3x + 2y = 6

2y = 3x + 6

Dividing all through by 2, we have:

2y/2 = 3x/2 + 6/2

y = 3x/2 + 3

In conclusion, a graph which represents the linear equation (y = 3x/2 + 3) shows a proportional relationship between the value of x and y.
