A florist is arranging a bouquet of daisies and tulips. He wants twice as many daisies as tulips in the bouquet. If the bouquet contains 24 flowers, how many daisies are in the bouquet?
(A) 8 daisies (B) 12 daisies (C) 16 daisies (D) 24 daisies

Answers

The correct option is (c) 16 daisies

If the bouquet contains 24 flowers then total 16 daisies are in the bouquet.

What are polynomial functions ?

In mathematics, polynomial function can be defined as the equation which consist of coefficient, variables and exponents. All the equations such as quadratic equation, cubic equation which has non  negative number as their powers are part of polynomial equation.

Some examples of polynomial equation are :

2x+53x = 93x² + 5x+19(x-3)³

Now, for the given  question,

let d = number of daisies

     t = number of tulips

according to statement polynomial equation  is,

  d + t = 24    , say equation (i)

Twice as many daisies as tulips:

  d=2t

Put the value of d in equation (i)

  2t + t = 24

  3t = 24

  t = 8

As, number of daisies = 2 (number of tulips)

Therefore, d = 2t = 2 (8) = 16

Thus,  total 16 daisies are in the bouquet.

The graph shows the height of a football after being thrown. Use the graph to estimate the x- and y-intercepts of the function, where the function is positive and negative, and interpret the meanings in the context of the situation.

Answers

From the graphed function, it is found that:

The x-intercept is of 5. This means that the football will hit the ground after 5 seconds.The y-intercept is of 6. This means that at time 0, the football was at a height of 6 feet.The function is always positive, which means that the ball is in the air for 6 seconds.The graph shows that the function is never negative.

What are the intercepts of a function f(x)?

The x-intercept of a function f(x) is the value of x when the f(x) = 0, that is, the value of x when the function crosses the x-axis.The y-intercept of a function f(x) is the value of y when the x = 0, that is, the value of y when the function crosses the y-axis.

From this graph, it is found that:

The x-intercept is of 5. This means that the football will hit the ground after 5 seconds.The y-intercept is of 6. This means that at time 0, the football was at a height of 6 feet.

When a function is positive and when it is negative?

A function is positive when it is above the x-axis.A function is negative when it is below the x-axis.

Hence:

The function is always positive, which means that the ball is in the air for 6 seconds.The graph shows that the function is never negative.

A rational expression that would produce the given number line is f(x) = 1 /[(x + 4) · (x - 1) · (x - 3)].

How to derive a rational equation that observe the sign characteristics on the number line

Rational equations are equations of the form P(x) / Q(x), where P(x) and Q(x) are polynomials representing the numerator and the denominator of the expression. In this problem we assume a rational equation where P(x) = 1 and Q(x) is polynomial in factored form, where each root represents an indetermination. Then, we derive the following rational expression that observes the sign behavior on the number line:

f(x) = 1 /[(x + 4) · (x - 1) · (x - 3)]

This expression guarantees the sign behavior:

f(x) < 0 for x < - 4.f(x) > 0 for - 4 < x < 1.f(x) < 0 for 1 < x < 3.f(x) > 0 for x > 3.

The equivalent fractions here are: 14/18 ,  21/27 , 28/36 , 35/45 , 42/54.

Given, the number 7/9

7/9 = (7/9 × 2/2) = 14/18

7/9 = (7/9 × 3/3) = 21/27

7/9 = (7/9 × 4/4) = 28/36

7/9 = (7/9 × 5/5) = 35/45

7/9 = (7/9 × 6/6) = 42/54

hence the equivalent fractions here are:

the customer should buy?

O 11
O 16

Answers

A customer should buy minimum 16 boxes of pavers.

In this question, a customer is ordering brick pavers to cover a rectangular walkway that is 3 feet by 15 feet and a square sitting area that is 6 feet on a side.

First we find the total area that will be covered by  pavers.

Area of rectangle = length × width

Area of rectangle = 15 × 3

Area of rectangle = 45

And the area of square = side²

             area of square =   6²

             area of square =  36

So, the total area would be,

Total area = area of rectangle + area of square

Total area = 45 + 36

Total area = 81

So, the total area is 81 square feet.

one box of pavers covers 5.28 square feet.

So using unitary method,

81 / 5.28

= 15.534

≈ 16 boxes

This means, approximately 16 boxes will require to cover the above area.

Therefore, the customer should buy minimum 16 boxes of pavers.

Round your answer to the nearest tenth.

The height (h) of this rectangular prism is equal to 3 units.

What is Pythagorean theorem?

Pythagorean theorem can be defined as a mathematical expression in Euclidean geometry that can be used to solve for any of the three (3) side lengths of a right triangle.

How to determine the height (h) of this rectangular prism?

In order to determine the height (h) of this rectangular prism, we would first of all determine the diagonal of the base by applying Pythagorean theorem:

d² = l² + b²

d² = 4² + 3²

d² = 16 + 9

d² = 25

d = √25

d = 5 units.

Therefore, the diagonal of the base of this rectangular prism is equal to 5 units.

Now, we can determine the height (h) of this rectangular prism:

x² = d² + h²

h² = √34² - 5²

h² = 34 - 25

h² = 9

h = √9

Height, h = 3 units.

Therefore, the height (h) of this rectangular prism is equal to 3 units.

Answer:

Step-by-step explanation:

|2x - 2| > 2 (greater than 2)

the dilution set is the set of all x values, for which this inequality is true.

and that means

|2x - 2| has to have greater value than the value 2, which is represented by the constant, horizontal line y = 2.

the y values are aligned with the y-axis, which goes up and down. the higher up, the larger the y value.

so, only the values of |2x - 2| higher than 2 keep the inequality true.

so, a.) is the right answer. it is above the line.

b.) below would mean "< 2".

c.) intersects would mean "= 2".

d.) does not intersect would mean "<> 2".

please consider, the intersection points with the line are NOT included, because we have "> 2".

A composite function exists as a function that depends on another function. A composite function exists formed when one function exists substituted into another function.

The value of f(g(x)) = (2x-6)/2 and g(f(x)) =  x - 6.

What is meant by composition function?

In mathematics, function composition exists as an operation ∘ that takes two functions f and g, and has a function h = g ∘ f such that h(x) = g. In this operation, the function g exists used to the result of applying the function f to x.

Function composition is a mathematical procedure where two functions, f, and g, are taken and a function, h = g ∘ f, is produced such that h(x) = g(f(x)). The function g exists used in this operation on the outcome of applying the function f to x.

Let the given functions be f(x) = x-3/2 and g(x) = 2x - 3

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

simplifying the above equation, we get

f(g(x)) = f(2x-3) = ((2x-3) - 3)/2

f(g(x)) = f(2x-3) = (2x-6)/2

f(g(x)) = (2x-6)/2

g(f(x)) =  g(x-3/2)

simplifying the above equation, we get

g(f(x)) =  g(x-3/2) = 2((x-3)/2) - 3

g(f(x)) =  g(x-3/2) = x - 6

g(f(x)) =  x - 6

Therefore, the value of f(g(x)) = (2x-6)/2 and g(f(x)) =  x - 6.

a. The translation f₁(x)=b x-h of f is equivalent to a vertical stretch or compression of f .

Answers

The function f₁(x) can be either vertical stretch or vertical compress: TRUE

What do we mean by Logarithmic Function?The following is the formula for basic logarithmic functions: Where b > 0, f(x) = logbx(r), y = logbx.It is the reciprocal of the exponential function x=b∧y.Log functions are denoted by natural logarithm (ln) and common logarithm (log).

Here are a few examples of logarithmic functions:

f(x) = ln (x - 2)g(x) = log2(x + 5)-2h(x) = 2 log x, etc.

So,

Given function:

f(x) = bˣg(x) = logbx

Then,

f₁(x)=b^(x-h)f₁(x)=b^x/b^h

Now, Put bˣ=f(x):

f₁(x)=f(x)/b^hf₁(x)=b^(-h)f(x)f₁(x)=c f(x)

We discovered that:

c=b^(-h)

So, depending on the values of b and h, c can be greater than or less than one.

Therefore, the statement "the function f₁(x) can be either vertical stretch or vertical compress" is TRUE.
