The titanium has a mass value of 563.75 grams

From the question, the given parameters are

Density of titanium = 4.51 g/cm^3

Volume of benzene = 125.0 cm^3

The mass of the titanium is then calculated using

Density = Mass/Volume

Make Mass the subject of the formula

So, we have

Mass = Volume  x Density

Substitute the known values in the above equation

So, we have the following equation

Mass =125.0 x 4.51

Evaluate the product in the equation

Mass = 563.75

Hence, the mass of the titanium is 563.75 grams

The perimeter of the triangle is computed adding the length of each side. That is,

P = (2x - 2) + (2x - 2) + x

P = (2x + 2x + x) + (-2 - 2)

P = 5x - 4

Substituting with P =56 and solving for x:

-4 is the numerical value of x which forms part of the coordinates of the points with a slope of -1/4.

Slope is simply expressed as change in y over the change in x.

It is expressed as;

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

Given the data in the question;

Point 1( x, 4 )

Point 2( 20, -2 )

To determine the value of x, plug the slope m, x and y values into the slope formula.

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

-1/4 = ( -2 - 4 )/( 20 - x )

-1/4 = ( -6 )/( 20 - x )

Cross multiply

-1( 20 - x ) = 4( -6 )

-20 + x = -24

x = -24  + 20

x = -4

Therefore, the numerical value of x is -4.

The distance between you and your friend is changing at the rate of 28 miles per hour after you travel 3 miles.

According to situation,

You are going in east direction with a rate of 16miles per hour and your friend is going towards 12 miles per hour at the rate of 12 miles per hours.

Let us say you cover L distance in east direction and your friend covers B distance in north direction,

Time taken by you to cover 3miles,

Time = Distance L/speed

time = 3/16 hours.

Distance B covered by friend in 3/16 hours,

distance B = speed x time

Distance B = 3/16 x 12

Distance B = 9/4 miles.

As both are going perpendicular to each other,

The distance between you and your friend X can be calculated by the Pythagoras theorem,

X² = L² + B²

Differentiating with respect to time t,

2dX/dt = 2(L)dL/dt + 2(B)dB/dt

As we know,

dL/dt = 16 miles/hour and,

dB/dt = 12 miles/hour,

L = 3 miles,

B = 9/4 miles.

Putting all the values,

2dX/dt = 2(3)(16) + 2(9/4)(12)

dX/dt = 48 + 27

dX/dt = 75 miles per hour.

The distance between you and your friend will change at the rate of 75 miles/hour.

The expansion of the given expressions of exponents are:

22. (b) a²· (a⁰)³ ÷ a¹¹ =  a⁻⁹

22. (f) {(a³a⁴)÷ a⁻³} /{a·((a²a)³)⁴} =  a⁻²⁷

Product rule for exponents state that product of two numbers with same base is given by adding their powers.

That is aⁿ × a ˣ = aⁿ⁺ˣ

Quotient rule for exponents state that the quotient of two numbers with same base is given by subtracting the exponent of denominator from numerator.

That is aⁿ ÷ a ˣ = aⁿ⁻ˣ

Power rule : (aⁿ)ˣ = aⁿˣ

22. (b) a²· (a⁰)³ ÷ a¹¹

       ⇒a²· (a⁰)³ ÷ a¹¹ = a².a⁰ ÷ a¹¹ (using power rule (a⁰)³ = a⁰)

     ⇒a²· (a⁰)³ ÷ a¹¹ =  a²⁺⁰ ÷ a¹¹  ( using product rule a².a⁰= a²⁺⁰ )

     ⇒a²· (a⁰)³ ÷ a¹¹ =  a²÷ a¹¹ = a²⁻¹¹ ( using quotient rule a²÷ a¹¹  =  a²⁻¹¹)

     ⇒a²· (a⁰)³ ÷ a¹¹ =  a⁻⁹

Therefore, expression  a²· (a⁰)³ ÷ a¹¹  is  a⁻⁹

                                                   using power rule (a³)³ = a³⁽³⁾)

         =  {a¹⁰} /{a·(a⁹)⁴}  

         =  {a¹⁰} /{a·a³⁶}          ( using power rule (a⁹)⁴ = a⁹⁽⁴⁾ =a³⁶)

        =  {a¹⁰} / {a¹⁺³⁶}          ( using product rule a·a³⁶ = a¹⁺³⁶)

        = { a¹⁰} / {a³⁷}          

       =  a¹⁰ ⁻ ³⁷                  ( using quotient rule a¹⁰ ÷ a³⁷ = a¹⁰ ⁻ ³⁷  = a⁻²⁷)

The 95% confidence interval will be more extensive than the 90% confidence interval

In measurements, the probability that a population boundary will fall between a bunch of values for a specific level of the time is alluded to as a certainty stretch. Investigators every now and again utilize certainty goes that incorporate 95% or the vast majority of expected perceptions. Thus, it could be presumed that there is a 95% probability that the genuine worth falls inside that reach assuming that a point gauge of 10.00 with a 95% certainty time frame - 10.50 is determined utilizing a factual model.

The degree of conviction or vulnerability in a testing cycle is estimated by certainty spans.

Also, they are utilized in relapse examination and speculation testing.

To decide measurable importance, analysts often join certainty spans with p-values.

95% or almost 100% certainty levels are most often utilized in their development.

Solution for angle x is gotten from the clue in A C > D F

The most appropriate choice for equation of line in slope intercept form will be given by-

Rate of change is 8 and rate of change represents slope of the line

What is equation of line in slope intercept form?

Equation of line in slope intercept form is written as y = mx +c

m is the slope of the line and c is the y intercept of the line.

The distance between the origin and the point where the line cuts the x axis is the x intercept

The distance between the origin and the point where the line cuts the y axis is the y intercept

Here,

Let the number of classes be x

Total cost of classes = y

Let the equation of line be y = mx + c

Three classes cost $36

Putting x = 3, y = 36

36 = 3x + c .............. (1)

Seven classes cost $68

Putting x = 7, y = 68

68 = 7x + c ............... (2)

Subtracting equation (2) from (1),

4x = 32

[tex]x = \frac{32}{4}[/tex]

x = 8

Putting the value of x in (1)

[tex]3 \times 8 + c = 36\\24 + c = 36\\c = 36 - 24\\c = 12[/tex]

Equation of line is y = 8x + 12

Answer:

Step-by-step explanation:

Given school costs of $36 for 3 classes and $68 for 7 classes, you want to know the rate of change and its meaning.

The "rate of change" in this context is the change in cost for one additional class. It can be found by ...

  rate of change = (change in classes) / (change in cost)

  rate of change = ($68 -$36)/(7 classes -3 classes) = $32/(4 classes)

  rate of change = $8/class

This "rate of change" is the additional cost for the addition of one class. It is the cost per class.
