Answer: The diameter of a pizza is 20 inches.

The range of possible values for x is 0<x<20

The Range is the difference between the lowest and highest values.

In any triangle, the smallest angle is opposite to the smallest side.

So, In ΔABD , the side which faces ∠ABD is AD whose length is 32 units.....(1)

And, in ΔCBD, the side which faces ∠CBD is CD whose length is 20 units....(2)

Now, from equations (1) and (2) We get,

∠ABD < ∠CBD

So, ∠ABD lies between 0° to 48°

0<4x+8<48

Subtract 8 on both sides

-8<4x<40

Divide by 4

-2<x<10

As ∠ABD lies between 0° to 48°, so 0<x<10 is the range.

Hence, 0<x<10 is the range of possible values for x.

The true statement is The value of g(1) is 3 .

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

g(x)=f(x-3)

When x= 1

g(1) = f(-2)= 3

Average rate of change for interval 5 to 11 boxes is 4.5 , 11 to 20 boxes is 6 and 20 to 25 boxes is 3.2

Average rate of change can be defined as slope of function between two fixed values of x. It can also be defined as change in function per unit or we can say as an average.

Average rate of change (from x = a to x=b) = [tex]\frac{f(b)-f(a)}{b-a}[/tex]

Given table can we represented as No.of boxes = x

Total weight = y

So, for x = 5 , y = 18

x = 11 , y = 45

x = 20 , y = 99

The probability that the marble is red or blue is 0.6923 or 69.23% if the bag contains five red marbles, four blue marbles, and four yellow marbles. You randomly pick a marble.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.

We have the total number of marbles = 5+4+4 =13

Total number of red and blue marble = 5+4 = 9

The probability that the marble is red or blue = 9/13 = 0.6923 or

The missing terms are 34t and 0.

Finding the solution to linear equations in one, two, three, or more variables is referred to as solving a linear equation. In simple words, finding the values that satisfy a Linear equation.

Here we have

Equation 3(18t +1) = 20t +3  

Let's solve the given expression to get the missing step

=> 3(18t +1) = 20t +3

Multiply (18t + 1) by 3

=> 54t + 3 = 20t + 3

Subtract 3 from both sides

=> 54t + 3 - 3 = 20t + 3 - 3

=> 54t = 20t

Subtract 20t from both sides  

=> 54t - 20t = 20t - 20t    

=>  34t = 0

Divide by 34 into both sides

=> 34t/34 = 0/34

Hello,

I hope you and your family are doing well!

To solve for V, we can start by subtracting 13 from both sides of the equation:

|v-8| = 16

Since the absolute value of a number is always nonnegative, we know that the value inside the absolute value must be either positive or zero. This means that we have two possible cases to consider:

Case 1: v-8 > 0

In this case, we can drop the absolute value symbols and solve the equation:

v-8 = 16

v = 24

Case 2: v-8 = 0

In this case, we can drop the absolute value symbols and solve the equation:

v-8 = 0

v = 8

So the possible values of V are 8 and 24.

|v-8| + 13 = 29

subtract 13 from both sides

|v-8| = 16

form two equations:

v-8 = 16 -(v-8) = 16

v-8 = 16

add 8 to both sides

v = 24

-(v-8) = 16

-v+8 = 16

subtract 8 from both sides

-v = 8

divide both sides by a -1

v = -8

check work:

|v-8| + 13 = 29

|24-8| + 13 = 29

|16| + 13 = 29

29 = 29

|v-8| + 13 = 29

|-8-8| + 13 = 29

|-16| + 13 = 29

Rounded to 5 decimal places, the initial mass of the sample was 48.00000 mg, and the mass 7 weeks after the start was 0.00002 mg.

What is the half-life of a substance?

Half-life is the time required for the amount of something to fall to half its initial value. The converse of half-life is doubling time.

The half-life of a substance is the time it takes for half of the initial mass of the substance to decay.

Since the half-life of Palladium-100 is 4 days, after 4 days, the mass of the sample will be reduced to half of its initial value. After 8 days, it will be reduced to a quarter of its initial value, and after 12 days it will be reduced to an eighth of its initial value.

We are given that after 12 days, the mass of the sample is 6 mg. This means that the initial mass of the sample was 8 * 6 mg = 48 mg.

After 7 weeks (7 * 7 = 49 days), the mass of the sample will be reduced by a factor of

              =  [tex]8^{(49/4) }[/tex]

             = [tex]8^{12.5}[/tex] =

approximately [tex]2.6 * 10^6[/tex]. The mass of the sample after 7 weeks will be approximately [tex]\frac{6 mg }{2.6 * 10^6}[/tex] = approximately [tex]2.3 * 10^{-6}[/tex] mg.

Step-by-step explanation:

This is a Taylor series because our center is non-zero.

The goal of Taylor series is to approximate non polynomial functions using Calculus.

So let's be intuitive.

In order to be accurate, we need to match the center value at some center a.

We know that cos(pi/2)=0, so our first constant should be 0.

[tex]q(x) = 0[/tex]

Next, we must be spot on with the linear approximation

at x=pi/2

we know that

[tex] \frac{d}{dx} \cos(x) = - \sin(x) = - \sin( \frac{\pi}{2} ) = - 1[/tex]

We also want to divide this by 1! , which is just one so our constant there is

-1, since we want to use this as an linear approximation and we want to be general, and we have a center to stay in respect to,

our next term is

[tex] 0 - 1(x - \frac{\pi}{2} ) {}^{1} [/tex]

Next, up, we must be similar in concavity.

So we take the second derivative of cosine which is just

[tex] - \cos(x) = - \cos( \frac{\pi}{2} ) = 0[/tex]

Since our constant is 0, we can skip this, even if we divide by 2!

Our fourth term is the third derivative of cosine

which is

[tex] \sin(x) = \sin( \frac{\pi}{2} ) = 1[/tex]

We then divide that by 3!, which becomes

[tex] \frac{1}{6} [/tex]

since we want to use this as an cubic approximation and we want to be general, and we have a center to stay in respect to,

our next term is

[tex] - (x - \frac{\pi}{2} ) {}^{} + \frac{1}{6} (x - \frac{\pi}{2} ) {}^{3} [/tex]

Let do one more term,

we know the 5th term is the fourth derivative of cosine evaluated at x=pi/2, which is just 0 so we can skip it.

The 6th term is the fifth derivative of cosine evaluated at x=pi/2, which is -1, then we divide by 5!, so we get

[tex]q(x) = - (x - \frac{\pi}{2} ) + \frac{1}{6} (x - \frac{\pi}{2} ) {}^{3} - \frac{1}{120} ( x - \frac{\pi}{2} ) {}^{5} [/tex]

Using the approximations, plug in 1.5 for x and we get approximately

Trigonometry is the branch of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and acronyms (csc).

Given:

sin x= 12/ 13

So, B = √13² - 12² = √169 - 144 = √25 = 5

cos x= -5/ 13

So, sin 2x= 2 sin x cos x =2 (12/13)(-5/13) = -120/169

and, cos 2x= 1- 2 sin²x

                  = 1- 2( 144 / 169)

                  = -119/ 169

and, tan 2x = sin 2x/ cos 2x = 120/ 169 / (- 119/ 169)= 120/ 119

equation, a declaration of equivalence between two expressions with variable- and/or number-filled expressions. In essence, equations are questions, and efforts to discover a method for answering them have fueled the growth of mathematics. Equations range in complexity from straightforward addition-and-multiplication equations in mathematics through differential equations, exponential equations that use exponential expressions, and integral equations.

Let's initially configure our system by giving the letters x and y meanings. Assume x is the number of kids and y is the number of adults.

Children are priced at $1.50, while adults are priced at $4.00. We multiply the total number of children, x, by 1.5 to get how much each child will cost. 1.5x is used to indicate this. We will use 4y for adults, whose entry fee is $4. On the specified day, $1094 in total revenue was earned. This sum requires the addition of 1.5x and 4y.

1.5x + 4y = 1094 works for the money equation involved.

Second equation: The total number of individuals present on the day is 283. X and Y, or the number of children and adults, must be added together to arrive at this figure.

x + y = 396

System of equations:

1.5x + 4y = 1094

x +   y = 396

Thus,

x + y = 396  

y = 396- x

Substitute y = 396 - x into the first equation.

1.5x + 4 (396 - x) = 1094

1.5x + 1584 - 4x = 1094  

1584 - 2.5x = 1094      

-2.5x = -490                  

x = 196

Substitute x =196 back into y = 396 - x

y = 396 - 196 = 200

Therefore by solving the equations we get to know that 196 children and  200 adults were present on that day.
