Answer:

[tex]y=\dfrac{3}{2}\cdot 2^x[/tex]

Step-by-step explanation:

The general equation of the exponential function is

[tex]y=a\cdot b^x[/tex]

If the graph of the exponential function passes through the points (-2, 0.375) and (7, 192), then their coordinates satisfy the equation:

[tex]0.375=a\cdot b^{-2}\\ \\192=a\cdot b^7[/tex]

Divide the second equation by the first:

[tex]\dfrac{192}{0.375}=\dfrac{a\cdot b^7}{a\cdot b^{-2}}=\dfrac{b^7}{b^{-2}}\\ \\512=b^9\\ \\b=\sqrt[9]{512}=2[/tex]

Substitute it into the second equation:

[tex]192=a\cdot 2^7\\ \\192=a\cdot 128\\ \\a=\dfrac{192}{128}=\dfrac{96}{64}=\dfrac{48}{32}=\dfrac{6}{4}=\dfrac{3}{2}[/tex]

So, the equation of the exponential function is

[tex]y=\dfrac{3}{2}\cdot 2^x[/tex]

Answer:

interest earned= 292.878

the future value of an annuity= 892.878

Step-by-step explanation:

[tex]\dfrac{4a+12}{a+3}[/tex]

That always equals 4 except when [tex]a=-3[/tex]

So the restriction is

Answer:  a ≠ -3

Answer:

The restriction is at a=-3

Step-by-step explanation:

You need to see if there are like terms. If there are that is a hole. For example you can a 4 out of the equation like so.

4(a+3)/a+3.

since they both have a+3 that is a hole. so a+3=0 so a=-3 is a restriction

Step-by-step explanation:

√18 = √9·√2 = 3·√2.  

√2 is an irrational, non-repeating decimal (my calculator shows it to be approx. 1.414213562..... )

and so √18 is the same.

Answer:

Irrational number, Non-repeating decimal

Step-by-step explanation:

Dictonary definition of

IRRATIONAL NUMBER:

"(of a number, quantity, or expression) not expressible as a ratio of two integers, and having an infinite and nonrecurring expansion when expressed as a decimal. Examples of irrational numbers are the number π and the square root of 2."

Answer:

1) 9/cos(θ)

2)4[tex]\sqrt{3}[/tex](cos(198) +isin(198))

3)z= cos(π/3) +isin(π/3)

Step-by-step explanation:

x=9

i.e. x= 9 +i0

θ= tan^-1 (0/9)

θ= tan^-1 (0)

=0

hence z= r(cosθ +i sinθ)

            = 9(cos 0 + isin 0)

            = 9

As cos (0) = 1 hence polar form of x=9 is 9/cos(θ) where θ=0

2)

Given

z1=2[tex]\sqrt{3}[/tex]( cos(116)+isin(116))

z2=2(cos(82)+isin(82))

As per the product formula od complex polar numbers:

z1.z2= r1.r2(cos(θ1+θ2) +isin(θ1+θ2) )

Putting the values

          = 4[tex]\sqrt{3}[/tex](cos(198) +isin(198))

3)

z= 1/2 + i[tex]\sqrt{3}[/tex]/2

r= [tex]\sqrt{(1/2)^{2}+(\sqrt{3}/2) ^{2}  }[/tex]

r = [tex]\sqrt{1/4 +3/4} \\\sqrt{4/4}\\\sqrt{1}[/tex]

r=1

θ= tan^-1 [tex](\sqrt{3}/2 ) / (1/2)[/tex]

= tan^-1[tex]\sqrt{3}[/tex]

=60

=π/3

hence

z= cos(π/3) +isin(π/3) !

There are 479,001,600 different combinations of songs that can be played without repeating a song

An MP3 player with a playlist of 12 songs can be played in 479,001,600 different orders.

An MP3 player with a playlist of 12 songs can play each song in random order without repetition.

To calculate the number of different orders the songs can be played, we can use the concept of permutations.

In this case, we have 12 songs and want to find the number of different ways they can be arranged.

The formula for permutations is n! / (n - r)!, where n is the total number of items and r is the number of items being arranged.

In this case, n is 12 and r is also 12 (since we want to arrange all the songs).

So the formula becomes 12! / (12 - 12)!. Since 12 - 12 is 0, the denominator becomes 0!.

The value of 0! is defined as 1, so we can simplify the formula to just 12!.

Using a calculator or factorial table, we can calculate that 12! (12 factorial) is equal to 479,001,600.

Therefore, there are 479,001,600 different orders in which the songs can be played on the MP3 player.

Answer:

Usual, because the result is between the minimum and maximum usual values.

Step-by-step explanation:

To identify if the value is usual or unusual we're going to use the Range rule of thumbs which states that most values should lie within 2 standard deviations of the mean. If the value lies outside those limits, we can tell that it's an unusual value.

Therefore:

Maximum usual value: μ + 2σ

Minimum usual value: μ - 2σ

In this case:

μ = 153.1

σ = 18.2

Therefore:

Maximum usual value: 189.5

Minimum usual value: 116.7

Therefore, the value of 187 lies within the limits. Therefore, the correct option is D.  Usual, because the result is between the minimum and maximum usual values.

Answer:

D. Usual, because the result is between the minimum and maximum usual values

The perimeter of question #1 is 36. The second one is 24 then the third is 19 then 28 then 54

Step-by-step explanation:

Answer:

The perimeter of one is 36. The second one is 24. The third is 19. The fourth is 28. The last is 54.

Step-by-step explanation: Adding all the sides is how you find perimeter. Use πr + 2r, where r is the radius minus the side of the semicircle that touches the other shape since that is inside the shape.

Answer: The correct option is A.

Explanation:

The given function is,

To find the graph of this function after the reflecting across y-axis, first we have to find the graph of the equation.

The value of the function is 2 when x=0, so, the graph of given equation intersect the y-axis at 2.

In the equation . Since , so the given function is decreasing function

The value of f(x) is always positive, so the graph of f(x) is always above the x-axis. Thus, the graph must be above the x-axis after reflection across y-axis.

So, the option (2) and (4) and incorrect.

When we reflect the graph across the y-axis then,

It means when x approaches to large negative number the f(x) approaches to 0 and when x approaches to large positive number the f(x) approaches to infinite.

Therefore, the correct option is show in first graph.

ANSWER

[tex]x = 22 \: \: units[/tex]

EXPLANATION

The line from the center of the circle to the upper chord meets it at right angles, this means that, this line bisects the upper chord.

Hence the length of the upper chord is 2(11)=22 units.

Since the distance from the upper chord to the center is 12 units and the distance from the lower chord to the center is also 12 units, the two chords must be equal.

[tex] \therefore \: x = 22 \: units[/tex]

Check the picture below.

so we have two parallel lines, notice, the 115° are corresponding angles and thus equal,  the 65° and 55° angles are linear angles to 115° and 125° respectively.

that leaves us with a triangle with 65° and 55°, and since all interior angles in a triangle sum up to 180°, then the last angle must be 60°, which has a twin vertical angle across the junction.

since a full revolution or a full circle go-around is 360°, the other two twin vertical angles next to the green 60° angles must be 360° - 60° - 60° = 240°, and since they're twins, each takes half of 240°.

-6

To find the slope of the perpendicular line, start with the original slope, 1/6.

The slope of a perpendicular line is the opposite and inverse of the slope of the original line. So, start by finding the inverse. This is done by simply flipping the numerator and the denominator to get 6/1, which is simplified to 6.

Finally, find the opposite of 6. You can find the opposite of a number by multiplying or dividing it by -1. If it is a positive number, just add a negative sign, and if it is already a negative number, take away the negative sign. So, the opposite of 6 is -6, which is out final answer.

The sum of the lengths of two sides of a triangle must always be less than or equal to the third side. So, if we let the third side be x, we have:

[tex]\begin{cases}6+x\geq9\\x+9\geq6\\6+9\geq x\end{cases} \iff \begin{cases}x\geq3\\x\geq -3\\x\leq 15\end{cases} \iff \begin{cases}x\geq3\\x\leq 15\end{cases}[/tex]

Answer:

[tex]P(A\:or\:B)=\frac{7}{11}[/tex]

Step-by-step explanation:

If the two events are disjoint, then P(A or B)=P(A)+P(B).

We were given that:

[tex]P(A)=\frac{4}{11}[/tex]

and

[tex]P(B)=\frac{3}{11}[/tex]

This implies that:

[tex]P(A\:or\:B)=\frac{4}{11}+\frac{3}{11}[/tex]

We simplify the right hand side to obtain:

[tex]P(A\:or\:B)=\frac{4+3}{11}[/tex]

[tex]P(A\:or\:B)=\frac{7}{11}[/tex]

Answer:

5/11

How I got my answer:

For overlapping events, you would subtract P(A and B) from the sum of P(A) and P(B).

In this case, you would do 4/11 + 3/11, which equals 7/11 minus 2/11, which equals 5/11.

Step-by-step explanation:

Answer:

False

Step-by-step explanation:

The equation in slope-intercept form of a line is y=mx+b, where x and y can represent a point on the line by using the coordinates (x,y), m is the slope, and b is the y intercept.

To double check this equation, plug in the coordinates of the point (3,6) to make sure both sides of the equation equal to each other.

6 = -5(3) + 7

6 = -15 + 7

6 = -8

[tex]6 \neq -8[/tex]

Because the equation is invalid, the line does not pass through these points.

The statement is false because the equation y = -5x + 7 does not satisfy the point (3,6).

To determine if the equation y = -5x + 7 is the equation of a line that passes through the point (3,6) and has a slope of -5, we can plug the coordinates of the point into the equation to see if it satisfies the equation.

Substituting x = 3 and y = 6 into the equation gives us:
6 = -5(3) + 7,
which simplifies to:
6 = -15 + 7,
6 = -8, which is not true.

Therefore, the point (3,6) does not lie on the line with the equation y = -5x + 7. The equation y = -5x + 7 does, however, represent a line with a slope of -5, but since it does not pass through the point (3,6), the initial statement is false.

Answer:

E

Step-by-step explanation:

[tex]

y+8=4(x-5)

[/tex]

Put the the E coordinates.

[tex]

-8+8=4(5-5) \\

0 = 4\cdot 0 \\

\boxed{0=0\Longrightarrow E\in y+8=4x-20}

[/tex]

Hope this helps.

r3t40

By simplifying the given equation y + 8 = 4(x - 5) to y = 4x - 28 and substituting the points' coordinates, it is determined that Point B (5, 0) is the correct point that lies on the line described by the equation.

To determine which point lies on the line described by the equation y + 8 = 4(x - 5), we need to verify which of the given options, when substituted into the equation, will satisfy it. First, we will simplify the equation to its standard line equation form y = mx + b (where m is the slope and b is the y-intercept):

Now we can substitute the x and y values from each of the points into this equation and check which one holds true.

Thus, Point B (5, 0) is the point that lies on the line described by the equation.
