Given that f(x)=x2−4 and g(x)=x+3 , what are all the values of x for which f(g(x))=0 ?

Hello and Good Morning/Afternoon

Let's take this problem step by step:

To find the rate of change is essentially like finding a line's slope:

 ⇒ the x-values are the number of sodas

 ⇒ the y-values are the total costs

              ⇒ choose two sets of coordinates and find the slope

Let's put that into action

        ⇒ (24, 18)

        ⇒ (28, 21)

        [tex]Rate_.of_.change = \frac{21-18}{28-24} =\frac{3}{4}[/tex]

Since the rate of change is total cost over number of sodas

 ⇒ unit is 'total cost/number of sodas'

Answer: 3/4 total cost/number of sodas

Hope that helps!

Segment AC was dilated by a scale factor of 2 to form A'C' measuring 16  units

Transformation is the movement of a point from its initial location to a new location. Types of transformation are translation, rotation, reflection and dilation.

Dilation is the increase or decrease in the size of a figure.

Let us assume that segment AC was dilated by a scale factor of 2 to form C'A', hence:

A'C' = 2 * AC = 2 * 8 = 16 units

Segment AC was dilated by a scale factor of 2 to form A'C' measuring 16  units

Answer: B: 11 and 12

Step-by-step explanation:

- An integer is simply a whole number

- So consecutive integers are simply whole numbers that follow each other (ex: 1, 2, 3)

- The square root of 125 (in decimals) is 11.1803398875, meaning it is higher than 11 but less than 12

- So 11.1803398875 falls between 11 and 12, making the answer B

The percentage that the infuser will have to be filled to use the same amount of tea will be 90.23%.

The infuser for Lizeete is 7 cm high, 3 cm long and 1.5 cm wide. The volume will be:

= 7 × 3 × 1.5

= 31.5cm³

The tea infuser from the example, was the same except 7.9 cm high. Therefore, the volume will be:

= 7.9 × 3 × 1.5

= 35.5

Since it was filed to 80%, this will be:

= 80% × 35.5

= 31.5cm³

Therefore, the dimensions will work and the percentage to use the same amount of tea will be:

= 28.44/31.5 × 100

= 90.23%

The parabola opens down.

The sign of the second difference is positive.

The coordinates of the vertex is at (1, 3)

The equation of the axis of symmetry is x = 1

The optimal value of the parabola is at y = 3

The optimal value is considered a max value.

The x-intercepts is at (-1, 0) and (3, 0)

The y-intercept is at (0, 5/2)

In Science, volume is a unit of measurement which indicates the capacity of a container and it has the following units:

Next, we would convert the volume of Madison's diesel in centiliter to liter as follows:

1 centiliter = 0.01 liter

940 centiliter = X liter

Cross-multiplying, we have:

How to solve such time related questions?

The key concept for solving such questions is the relationship between speed, distance and time.

The relationship between them is Distance = Speed x Time

Given:-

Total time taken by girl to complete the trip = 15 minutes = [tex]\frac{1}{4}[/tex] hours

Speed while riding going = 6 miles per hour

Speed while coming back = 4 miles per hour

Total time taken by girl  =

Time taken while going +   Time taken while coming back      - (1)

  Let x be distance from home to store

       [tex]\frac{x}{6}[/tex] =  Time taken while going

[tex]\frac{x}{4}[/tex] = Time taken while coming back

    Substituting in (1) we get

      [tex]\frac{1}{4} = \frac{x}{6} + \frac{x}{4}[/tex]

      [tex]\frac{1}{4} = \frac{2x + 3x}{12}[/tex]

       [tex]\frac{1}{4} = \frac{5x}{12}[/tex]

      [tex]x= \frac{12}{20}[/tex]

    x = 0.6 miles

Answer:

a. The graph is concave up in the interval 0 ≤ x ≤ +∞

b. The graph is concave down in the interval -∞ ≤ x ≤ 0

To answer the question, we need to know what intervals are

Intervals are range of values in which a function is valid. It can either be the range of values of input or output of the function.

From the graph, we see that the function is concave up in the interval 0 ≤ x ≤ +∞

So, the graph is concave up in the interval 0 ≤ x ≤ +∞

From the graph, we see that the function is concave down in the interval -∞ ≤ x ≤ 0

So, the graph is concave down in the interval -∞ ≤ x ≤ 0

Using the side-splitter theorem, the segment length that would complete the proportion is GJ.

It should be noted that the side splitter theorem states that when a line intersects two sides of a triangle and is also parallel to the third side, then it'll divide the sides proportionally.

From the information given, it can be deduced that EF and HJ are parallel while H is on the side EG and J is on GF. Therefore, according to the theorem, GH/HE = GJ/JF

Left hand side can be expressed as;

2 divided by 9 = 2/9

Now, right hand side can be expressed as;

5/2 ÷ 5/4

The largest possible volume of the given box is; 96.28 ft³

Let b be the length and the width of the base (length and width are the same since the base is square).

Let h be the height of the box.

The surface area of the box is;

S = b² + 4bh

We are given S = 100 ft². Thus;

b² + 4bh = 100

h = (100 - b²)/4b

Volume of the box in terms of b will be;

V(b) = b²h = b² * (100 - b²)/4b

V(b) = 25b - b³/4

The volume is maximum when dV/db = 0. Thus;

dV/db = 25 - 3b²/4

25 - 3b²/4 = 0

√(100/3) = b

b = 5.77 ft

Thus;

h = (100 - (√(100/3)²)/4(5.77)

h = 2.8885 ft

Thus;

The probability that a simple random sample of 45 unemployed individuals will provide is 0.7372

Here, μ = 17.5, σ = 0.8944, x1 = 16.5 and x2 = 18.5.

We need to compute P(16.5<= X <= 18.5).

The corresponding z-value is calculated using Central Limit Theorem.

z = (x - μ)/σ

z1 ⇒ (16.5 - 17.5)/0.8944 = -1.12

z2 ⇒ (18.5 - 17.5)/0.8944 = 1.12

Therefore, we get

P(16.5 <= X <= 18.5) = P((18.5 - 17.5)/0.8944) <= z <= (18.5 - 17.5)/0.8944)

⇒ P(-1.12 <= z <= 1.12) = P(z <= 1.12) - P(z <= -1.12)

⇒ 0.8686 - 0.1314 = 0.7372

The principal limit theorem states that if you have a population with imply μ and trendy deviation σ and take sufficiently huge random samples from the populace with alternative, then the distribution of the pattern method may be about usually distributed.

The relevant limit theorem (CLT) states that the distribution of pattern manner approximates a normal distribution as the pattern size gets larger, regardless of the population's distribution. sample sizes identical to or extra than 30 are often considered enough for the CLT to preserve.

apply distributive method: a(b + c) = ab + ac

multiply variables

⇒ 9x + 27 = 4x - 3

collect like terms

⇒ 9x - 4x = -3 - 27

subtract like terms

⇒ 5x = -30

divide both sides by 5
