Reason:

See the screenshot below. I used GeoGebra to plot the points.

The sub group of points D, E, F form a bowl shaped region. Imagine a small parabola passing through these points. Point E is either the local min or very close to it. This is because point E is at the bottom of the bowl shape.

A) Composite function that represents how many flowers Iris can expect to bloom over a certain number of weeks is f[s(w)] = 50w + 25.

B) The unit of measurement for the composite function is flowers.

C) Number of the flowers for 30 weeks will be 1525.

A function is said to be a composite function when a function is written in another function. The composite function that represents the number of flowers is f[s(w)] = 50w + 25. and the number of flowers for 30 weeks is 1525.

Part A: Write a composite function that represents how many flowers Iris can expect to bloom over a certain number of weeks.

From the given data we will find the function for the number of flowers with time.

f(s) = 2s + 25

We have  s(w) = 25w

f[(s(w)]=2s(w) + 25

f[(s(w)] = 2 x ( 25w ) +25

f[s(w)] = 50w + 25.

Part B: What are the units of measurement for the composite function in Part A

The expression f[s(w)] = 50w + 25 will give the number of the flowers blooming over a number of the weeks so the unit of measurement will be flowers.

Part C: Evaluate the composite function in Part A for 30 weeks.

The expression f[s(w)] = 50w + 25 will be used to find the number of flowers blooming in 30 weeks put the value w = 30 to get the number of the flowers.

f[s(w)] = 50w + 25.

f[s(w)] = (50 x 30) + 25.

f[s(w)] = 1525 flowers.

Therefore the composite function is f[s(w)] = 50w + 25. unit will be flowers and the number of flowers in 30 weeks will be 1525.

Benjamin has 340 cents or $3.40.

Proportion in Mathematics is an equation where two or more ratios are made to be equal.

If a : b = c : d, then we can write a/b = c/d

We know that,

1 nickel = 5 cents

8 nickel = x cents

Using ratio and proportion,

1 : 5 = 8 : x

x = 8 × 5 = 40 cents

Similarly,

1 quarter = 25 cents

12 quarters = 12 × 25 = 300 cents

Total cents Benjamin has = 300 + 40 = 340 cents = $3.40

Hence, Benjamin has a total of $3.40.

The probability that a student is a female or major in civil engineering is 62%

At a certain college, 49% of the students are female, and 21% of the students major in civil engineering. Furthermore, 8% of the students both are female and major in civil engineering. What is the probability that a randomly selected female student majors in civil engineering?

Let A represent Female and B represents civil engineering.

The above representation means that the given parameters are:

The required probability is calculated as:

P(A or B) = P(A) + P(B) - P(A and B)

This gives

P(A or B) = 49% + 21% - 8%

Evaluate

P(A or B) = 62%

Hence, the probability that a student is a female or major in civil engineering is 62%

Answer:

(3, 0)

Step-by-step explanation:

Given:

Rotation rule for -90°:  (x, y) → (y, -x)

As the center of rotation is not the origin, we cannot simply apply the above rule.

To rotate an image around a point other than the origin:

1.  Subtract each point of the image from the point of rotation:

⇒ Point of rotation - point of image

⇒ (-2, 6) - P = (-2, 6) - (-8, 1)

                    = (6, 5)

2. Rotate this about the origin by applying the rotation rule:

⇒ (x, y) → (y, -x)

⇒ (6, 5) → (5, -6)

Add the point of rotation to each rotated point of the image:

⇒ (5, -6) + (-2, 6) = (3, 0)

Therefore, the location of the image of P (-8, 1) after a counterclockwise rotation of 90° about (-2, 6) is (3, 0).

Answer:

[tex]g(x)=\log_3(x+4)[/tex]

Step-by-step explanation:

Translations

For [tex]a > 0[/tex]

[tex]f(x+a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units left}[/tex]

[tex]f(x-a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units right}[/tex]

[tex]f(x)+a \implies f(x) \: \textsf{translated}\:a\:\textsf{units up}[/tex]

[tex]f(x)-a \implies f(x) \: \textsf{translated}\:a\:\textsf{units down}[/tex]

Parent function:

  [tex]f(x)=\log_3x[/tex]

From inspection of the graph:

If there was a vertical translation, the end behaviors of both g(x) and f(x) would be the same in that the both functions would be increasing from -∞ in quadrant IV.

As the x-intercepts of both functions is different, and g(x) increases from -∞ in quadrant III, this indicates that there has been a horizontal translation of 4 units to the left.

Therefore:

[tex]g(x)=f(x+4)=\log_3(x+4)[/tex]

Further Proof

Logs of zero or negative numbers are undefined.

From inspection of the graph, [tex]x=-3[/tex] is part of the domain of g(x).

Therefore, input this value of x into the answer options:

 [tex]g(-3)=\log_3(-3)-4\implies[/tex] undefined

 [tex]g(-3)=\log_3(-3)+4\implies[/tex] undefined

 [tex]g(-3)=\log_3(-3-4)=\log_3(-7)=\implies[/tex] undefined

 [tex]g(-3)=\log_3(-3+4)=\log_3(1)=0[/tex]

Hence proving that [tex]g(x)=\log_3(x+4)[/tex]

The equation that represents g(x) is:  [tex]g(x) = log_3(x + 4)[/tex]

The correct answer is: the fourth option:

[tex]g(x) = log_3(x + 4)[/tex].

Here, we have to find the equation that represents g(x) using f(x), we need to consider how the graph of g(x) is related to the graph of f(x).

The graph of f(x) = log base 3 of x starts from negative infinity in quadrant four, passes through (0, 1), and increases to positive infinity.

The graph of g(x) is increasing from negative infinity in quadrant two, passes through (0, -3), and increases to positive infinity.

So, we can see that the graph of g(x) is the graph of f(x) shifted 4 units to the left along the x-axis.

Therefore, the equation that represents g(x) is:

[tex]g(x) = log_3(x + 4)[/tex]

The correct answer is: the fourth option:

[tex]g(x) = log_3(x + 4)[/tex].

Any two consecutive number in which the greater number is positive and smaller number is negative will give the sum of 1.

The result we get after adding some quantity is called the sum of the data.

Given we need to find two numbers whose sum is 1,

So, we can consider in this case two consecutive numbers of opposite sign the greater number should have a positive sign and the smaller number should have negative sign,

For example =

-4+5 = 1

-3+4 = 1

-2+3 = 1

-9+10 = 1

So, any two consecutive number in which the greater number is positive and smaller number is negative will give the sum of 1.
