Difference quotient for f(x) = √x at (16,4) is  √16+h - 4 / h

Difference quotient is mathematical operation used to solve derivation of function by using following formula :

difference quotient = [tex]\frac{f(x+ h) - f(x) }{h}[/tex]

For the function f(x) =  √x at point (16,4)

f(x +h) = [tex]\sqrt{x+h}[/tex]  

putting value in formula

difference quotient =  [tex]\frac{\sqrt{x+h} -\sqrt{x} }{h}[/tex]

now , putting x = 16 ,

difference quotient = √16+h - √16 / h

taking square root of 16 ,

= √16+h - 4 / h

So, the required Difference quotient for the function at (16,4) is √16+h - 4 / h

option (d) is correct

x = y/3 + 4/3

Step-by-step explanation:

Solve for x:

y = 3 x - 4

y = 3 x - 4 is equivalent to 3 x - 4 = y:

3 x - 4 = y

Add 4 to both sides:

3 x = y + 4

Divide both sides by 3:

Answer: x = y/3 + 4/3

The positive difference the  numbers is given as 6.

We are told here that there is a pair of natural numbers whose sum is 52 and whose product is 667. We have to make use of the idea of simultaneous equations to obtain the numbers.

Let the numbers be x and y thus we have;

x + y = 52 ---- (1)

xy = 667 ------ (2)

x = 52 - y ------ (3)

Substituting (3) into (2)

(52 - y)y = 667

52y - y^2 = 667

y^2 - 52y + 667 = 0

Solving the quadratic equation we have;

y=23 or y=29

The difference between the numbers then becomes 29 - 23

= 6

Numer of footballers of other nationalities(n²)=36/4=9

Now total number of footballers= n¹+n²= 36+9 =45

The expected value for the game is -12.

Probability is the occurence of likely events. It is the area of mathematics that deals with numerical estimates of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1.

The probability of rolling a 2 or 5:

= P(2 or 5)

= 1/6 + 1/6 = 1/3

The probability of not rolling a 2 or 5:

The two expressions equivalent to v are:

Here we have the equation:

5*(3a - 1) - 2*(3a + 2) = 3*(a + 2) + v

And we want to find expressions equivalent to v, so to do that, we just need to isolate the variable v in one side of the equation, if we subtract:

3*(a + 2) in both sides we will get:

5*(3a - 1) - 2*(3a + 2) = 3*(a + 2) + v

5*(3a - 1) - 2*(3a + 2) - 3*(a + 2) = v

That is one of the equivalent expressions, to get the other, we can just simplify the left side.

5*(3a - 1) - 2*(3a + 2) - 3*(a + 2) = v

15a - 5 - 6a - 4 - 3a - 6 = v

Now we can group like terms:

15a - 6a - 3a - 5 - 4 - 6

6a - 15 = v

t = d/220 is the equation that shows how many hours (t) a trip takes in terms of the trip's distance (d).

Speed is calculated as follows: speed = distance/time. Calculating the units for speed requires knowledge of the units for both time and distance. Since the distance is measured in meters (m) and the time is recorded in seconds, the units in this example will be meters per second (m/s) (s).

Let the distance be d and the time is t.

The given speed of the train = 220km/hr

Time = d/speed

Rate Pratap can row in still water is 6.75 and Rate of current is 2.25

Step: 1

Let's y = speed of water and x = his speed of rowing in still water

Speed = Distance/Time (or)

Rate = Distance/Time

Step: 2

he row downstream in 2 hours

Rate in downstream = 18/2

Rate in downstream = 9

i.e.

x + y = 9

x = 9 - y ---(i)

Now, time taken by min to row in upstream = 4 hours

Rate in upstream = Distance/Time = 18/4

Rate in upstream = 4.5

i.e., x-y = 4.5 ---(ii)

Putting the value of x from equation (i) in equation(ii)

9 - y - y = 4.5

9 - 2y = 4.5

9 - 4.5 = 2y

y = 4.5/2

y = 2.25

Putting the value of y in equation (ii)

x - 2.25 = 4.5

x = 4.5 + 2.25

x = 6.75

The equation of the graph is y = 2[tex]x^{2}[/tex] + 9x + 4

A quadratic equation is a second-order polynomial equation in a single variable x

a[tex]x^{2}[/tex]+bx +c=0

with a ≠ 0 . Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

From the graph the roots of the equation are -4 and -1/2

so if x = -4, them x + 4 = 0 is a factor,

Also, if x = -1/2, then x + 1/2 = 0 is a factor

Multiply and expand the two factors

(x + 4)(x + 1/2) = 0

[tex]x^{2}[/tex] + x/2 +4x + 2 = 0

2[tex]x^{2}[/tex] + x +8x + 4 = 0

24 pints of 55% pure fruit juice and 16 pints of 80% pure fruit juice will be required to make 40 pints of a mixture that is 65% pure fruit juice.

According to the question,

We have the following information:

The first type is 55% pure fruit juice, and the second type is 80% pure fruit juice. The company is attempting to produce a fruit drink that contains 65% pure fruit juice.

Now, let's take x pints of 55% pure fruit juice and y pints of 80% pure fruit juice will be required to make 40 pints of a mixture that is 65% pure fruit juice.

So, we have:

x+y = 40

x = 40-y ...(1)

55x/100+80y/100 = 40*65/100

55x+80y = 40*65

Putting the value of x from equation 1:

55(40-y)+80y = 2600

2200-55y+80y = 2600

2200+25y = 2600

25y = 2600-2200

25y = 400

y = 400/25

y = 16 pints

Putting this value in equation 1:

x = 40-y

x = 40-16

x = 24 pints

Hence, 24 pints of 55% pure fruit juice and 16 pints of 80% pure fruit juice will be required to make 40 pints of a mixture that is 65% pure fruit juice.

Step-by-step explanation:

According to the trignonmentry of half angles, the value of sin(x/2) is  √(1-5/6)/2, cos(x/2) is √(1+5/6)/2 and the value of tan(x/2) is √11/6/(√(1 + 5/6)

Trigonometry of half angles

Trigonometry of half-angle formula is used to determine the exact values of the trigonometric ratios of angles such as 15° that is half of the standard angle 30° and 22.5° that is the half of the standard angle 45 and so on. So if θ is an angle, then the half angle is represented by θ/2.

Given,

Here we need to find if cos(x)=5/6 , and x is in quadrant I, determine the exact value of each of the following.

sin(x/2), cos(x/2), tan(x/2).

According to the concepts in trigonometry,

We know that the following formulas.

=> sin(x/2) = √(1-cosx)/2

=> cos(x/2) = √(1+cosx)/2

=> tan( x/2)=sin x/1+cosx

Here we know that cos (x) = 5/6

Thus implies that 5 is the opposite and 6 is the hypotenuse, then the adjacent is

Therefore, we can calculate the value of the adjacent a as,

=> a = √(6²-5²)

=> a = √36-25

=> a= √11

Therefore the value of sin x= √11/6

So, the value of sin(x/2)= √(1 - 5/6)/2

And the value of cos(x/2)= √(1 + 5/6)/2

Finally, the value of tan(x/2)=√11/6/(√(1 + 5/6)
