The graph of the exponential function is on the image at the end.

Here we have the exponential equation:

W(x) = 2^(x - 1)

To graph any function, we should find some points on the function, and to find, them, we need to evaluate the function in some values of x.

if x = 0

W(0) = 2^(0 -1 ) = 0.5

if x = 1

W(0) = 2^(1 - 1) = 2^0 = 1

if x = 2

W(0) = 2^(2 - 1) = 2^1 = 2

So we got the points (0, 0.5), (1, 1), and (2, 2) (you can try to find more points).

Now we need to graph them on the coordinate plane and draw a curve that connects them (with the general form of an exponential function).

The graph can be seen in the image below.

Answer:

A. 8100

Step-by-step explanation:

85 x 86

To estimate, we multiply 85*100, which is the easiest multiplication, as a multiplication by 100 is the same as placing two zeros at the end of the number.

85*100 = 8500

Since 86 < 100, 85*86 < 8500. Thus, the correct estimate is given by option A.

A polynomial function f(x) of degree 3 with given zeros, 2, -3 , 5 and condition f(3)=6 is given by f(x) = -1/2 (x-2)(x+3)(x-5).

Degree of the polynomial function is equal to 3.

Zero's of the polynomial function is equal to 2, -3 , 5 .

And f(3) = 6

If 2, -3, and 5 are zeros of f(x), then we can write function as,

f(x) = a(x-2)(x+3)(x-5)

where a is some constant.

To determine the value of a, we can use the fact that f(3) = 6.

Substituting x = 3 into the equation above, we get,

f(3) = a(3-2)(3+3)(3-5)

     = -12a

Here we have,

f(3) = 6, so we can set these two expressions equal to each other and solve for a,

⇒ -12a = 6

⇒ a = -1/2

Now we can substitute this value of a back into the equation for f(x) that we found earlier,

⇒ f(x) = -1/2 (x-2)(x+3)(x-5)

Therefore, a polynomial function f(x) of degree 3 with zeros 2, -3, 5, and f(3) = 6 is equal to f(x) = -1/2 (x-2)(x+3)(x-5).

Answer:

The maximum profit the florist will earn from selling celebration bouquets is $725.

The florist will break-even after one-dollar decreases when her profit is zero. From the graph, this occurs at x = 10. So the florist will break-even after 10 one-dollar decreases.

The interval of the number of one-dollar decreases for which the florist makes a profit from celebration bouquets is (0, 10). This is because the profit is positive for values of x between 0 and 10, and becomes negative after 10.

Answer:  30 students: $346.5

1 student: $11.55

Step-by-step explanation:

The total cost in dollars for admission and lunch for 30 students is $406.6 and for each student is $13.55.

The unitary method is a technique for solving a problem by first finding the value of single unit, and then finding the value the necessary value by multiplying the single unit.

According to the given question

Cost price for five students for taking admission to the museum and lunch is 36.25 and 31.50 respectively.

cost price for one student for taking admission in museum = \(\frac{36.25}{5} = $7.25\)

cost price for one student lunch = \(\frac{31.50}{5} = 6.3\)

Therefore,

The total cost for each student for the admission and lunch = 7.25+6.3 =

$13.55

And, the total cost for 30 students for admission and lunch = 30×$13.55 =$406.5

Hence, the total cost for admission to museum and lunch for each student is $13.55 and for 30 students is $406.6.

To find the value of Az in the geometric sequence, we can use the given information. The geometric sequence is represented as follows: A3, 60, 160, 06 = 9.

From this, we can see that the third term (A3) is 60 and the common ratio (r) is 160/60.

To find Az, we need to determine the value of the nth term in the sequence. In this case, we are looking for the term with the value 9.

We can use the formula for the nth term of a geometric sequence:

An = A1 * r^(n-1)

In this formula, An represents the nth term, A1 is the first term, r is the common ratio, and n is the position of the term we are trying to find.

Since we know A3 and the common ratio, we can substitute these values into the formula:

60 =\(A1 * (160/60)^(3-1)\)

Simplifying this equation, we have:

\(60 = A1 * (8/3)^260 = A1 * (64/9)\)

To isolate A1, we divide both sides of the equation by (64/9):

A1 = 60 / (64/9)

Simplifying further, we have:

A1 = 540/64 = 67.5/8.

Therefore, the first term of the sequence (A1) is 67.5/8.

Now that we know A1 and the common ratio, we can find Az using the formula:

Az = A1 * r^(z-1)

Substituting the values, we have:

Az =\((67.5/8) * (160/60)^(z-1)\)

However, we now have the formula to calculate it once we know the position z in the sequence.

y = x - 4 is  the equation of the line in slope-intercept form.

How do you interpret a slope-intercept form?

The data provided by that form can be used to graph a linear equation in slope-intercept form. As an illustration, the equation y=2x+3 indicates that the line's slope is 2 and that its y-intercept is located at (0,3). This reveals the single point at which the line passes as well as the direction in which we should draw the full line after that.

                slope (m) = y/x

                                = -2/2

Answer:

2) Strong Negative Correlation

Step-by-step explanation:

With the value of r we have both the information about the sign of the relationship and the strength of this relationship.

As the value of r is negative, we can conclude that the correlation between x and y is negative.

Also, as the absolute value of r is close to 1, we can conclude that this relationship is strong.

The strength can also be seen in the value of r2, which is also close to 1, but this value does not give information about the sign.

The value of the slope a, being negative, can also tell us that the relation between x and y is a negative correlation.

Answer:

The two true statements concerning this situation and equation are:

The car was bought for $15,000. (This is true because the initial value or starting value, represented by "a" in the equation, is $15,000.)

The value of the car is decreasing. (This is true because the common ratio, represented by "b" in the equation, is 0.85 which is less than 1. Therefore, the value of the car decreases with each passing year or period.)

Step-by-step explanation:

The given equation y = 15000 (0.85) x represents the value of a recently bought used car where y is the value of the car after x years, 15000 is the initial value or starting value of the car, and 0.85 is the common ratio.

The initial value of the car is $15,000, which means that at x=0, the value of the car is $15,000. This is because the initial value is represented by the constant value of "a" in the equation.

The common ratio of 0.85 means that the value of the car decreases by 15% each year or period. This is because the common ratio is less than 1, which indicates that the value of the car is decreasing over time. This decrease in value is represented by the exponent "x" in the equation, which represents the number of years that have passed since the car was bought.

Therefore, the value of the car is decreasing with each passing year or period. For example, after one year (x=1), the value of the car will be 0.85 times its previous value, which is $12,750. After two years (x=2), the value of the car will be 0.85 times its previous value of $12,750, which is $10,838.75, and so on.

let's bear in mind that complex roots never come alone, their conjugate sister is always with her, so if we have the complex root of "i" or namely "0 + i", her conjugate is also coming along, or "0 - i", so we really have four roots, so

\(\begin{cases} x = 0+i &\implies x -i=0\\ x = 0-i &\implies x +i=0\\ x = \sqrt{2} &\implies x -\sqrt{2}=0\\ x = 3 &\implies x -3=0\\ \end{cases} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{original~polynomial}{a ( x -i )( x +i )( x -\sqrt{2} )( x -3 ) = \stackrel{0}{y}}\hspace{5em}\stackrel{\textit{we are assuming that}}{a=1} \\\\\\ 1( x -i )( x +i )( x -\sqrt{2} )( x -3 ) = y\implies ( x -i )( x +i )( x -\sqrt{2} )( x -3 ) = y \\\\[-0.35em] ~\dotfill\)
