Answer:

Step-by-step explanation:

x-intercept: the intersection point of the graph with the x axis.

Therefore, the x-intercepts are x = 1 and x = 5 (look at the picture).

Here is what i figured out.

Answer:

First, to find the median, we have to order all numbers, from least to highest:

Now, we calculate the position of each quartile:

[tex]Q_{k}=\frac{k(n+1)}{4}\\Q_{1}=\frac{1(15+1)}{4}=4\\Q_{2}=\frac{2(15+1)}{4}=8\\Q_{3}=\frac{3(15+1)}{4}=12[/tex]

So, the first quartile is in the fourth position, the thirds quartile is in the twelfth position:

So, first quartile is 6.1. Second quartile is 14.6, and the third quartile is 27.1.

It's important to remember that the second quartile is the median. So the median is 14.6

Lastly, the interquartile range is the difference between the third and first quartile. So:

[tex]Q_{3}-Q_{1}=27.1-6.1=21[/tex]

Therefore, the interquartile range is 21.

Answer: Option A

[tex]\sigma ^ 2 = 2.25[/tex]

Step-by-step explanation:

The number of faces obtained by flipping the coin 9 times is a discrete random variable.

If we call this variable x, then, the probability of obtaining a face in each test is p.

Where [tex]p = 0.5[/tex]

If we call n the number of trials then:

[tex]n = 9[/tex]

The distribution of this variable is binomial with parameters

[tex]p = 0.5\\\\n = 9[/tex]

For a binomial distribution, the variance "[tex]\sigma^2[/tex]" is defined as

[tex]\sigma ^ 2 = np(1-p)[/tex]

[tex]\sigma ^ 2 = 9(0.5)(1-0.5)[/tex]

Answer:

C. The growth factor of g is twice the growth factor of f.

Step-by-step explanation:

Let's find the growth factor of g(x) by getting its equation. To do it, we are using the standard exponential equation:

[tex]y=a(b+1)^x[/tex]

where

[tex]a[/tex] is the initial value

[tex]b[/tex] is the growth factor

We know form our graph that g(x) passes throughout (0, 3), so [tex]x=0[/tex] and [tex]y=3[/tex].

Replacing values

[tex]3=a(b+1)^0[/tex]

[tex]3=a(1)[/tex]

[tex]a=3[/tex]

We also know from our graph the g(x) passes throughout (1, 12), so [tex]x=1[/tex] and [tex]y=12[/tex].

Replacing values

[tex]y=a(b+1)^x[/tex]

[tex]12=3(b+1)^1[/tex]

[tex]12=3(b+1)[/tex]

[tex]b+1=\frac{12}{3}[/tex]

[tex]b+1=4[/tex]

[tex]b=4-1[/tex]

[tex]b=3[/tex]

The growth factor of g(x) is 4.

Now, to find the growth factor of f(x), we just need to equate 1+b with [tex]\frac{5}{2}[/tex] and solve for b:

[tex]1+b=\frac{5}{2}[/tex]

[tex]b=\frac{5}{2} -1[/tex]

[tex]b=\frac{3}{2}[/tex]

[tex]b=1.5[/tex]

Finally, we can divide the growth factor of g(x) by the growth factor of f(x) to find how many times bigger is the growth factor of g(x):

[tex]\frac{3}{1.5} =2[/tex]

We can conclude that the growth factor of g is twice the growth factor of f.

Answer:

y = 3x² - 6x - 72

Step-by-step explanation:

Since the roots are x = - 4 and x = 6 then the factors are

(x + 4) and (x - 6) and the quadratic function is

y = a(x + 4)(x - 6) ← a is a multiplier, in this case 3, so

y = 3(x + 4)(x - 6) ← expand factors and distribute by 3

y = 3(x² - 2x - 24)

y = 3x² - 6x - 72

3x²-6x-72. The quadratic equation whose  roots are -4 and 6 with a leading coefficient of 3 is 3x²-6x-72.

The solutions of a quadratic equation are x = -4 and x = 6 with a leading coefficient of 3. The solutions are two real numbers which means that (x + 4) and (x - 6) are the factors of our unknown quadratic equation and the leading coefficient is 3.

[tex]3(x+4)(x-6)=0[/tex]

Expand (x+4)(x-6):

[tex]3(x^{2} -2x-24)=0\\3x^{2} -6x-72=0[/tex] which is our quadratic equation.

Given that the volume of a rectangular prism is length x width x height, this problem can be solved by setting up the equation 2w * w * 8 = 400, where w is the width and 2w is the length. Solving this equation, we find that the width is 5 feet and the length is 10 feet.

In mathematics, the volume of a rectangular prism is given by the formula length x width x height. We are given that the volume of the storage container is 400 cubic feet, its height is 8 feet, and the length is twice the width. Let us denote the width as w, then the length is 2w.

From the given volume formula, we have:

Length x Width x Height = Volume

Substituting the values, we get:

2w * w * 8 = 400

Solving this equation, we find:

w^2 = 25

Taking the square root of both sides, we get:

w = 5

Substituting w=5 into 2w, we find the length:

Length = 2*5 = 10

So the width of the container is 5 feet and the length is 10 feet.

Using the tangent theorem and the inscribed angle theorem, m∠YAC is: A. 38°

According to the tangent theorem, a right angle (90°) is formed at the point of intersection between the radius and the tangent of a circle.

m∠BAY = m(BY) = 52° (inscribed angle theorem)

Final answer:

The function f(x) = 4(2)^(-x) - 3 approaches -3 as x approaches infinity and decreases without bound as x approaches negative infinity, with a horizontal asymptote at y = -3.

Explanation:

The end behavior of a function describes what happens to the function's values as x approaches infinity or negative infinity. For the function f(x) = 4(2)^(-x) - 3, as x approaches infinity, the term 2^(-x) approaches zero, because any non-zero base raised to the power of negative infinity is zero. Thus, the function approaches -3. Conversely, as x approaches negative infinity, the term 2^(-x) grows exponentially, and the function's values decrease without bound, heading towards negative infinity. However, since f(x) involves a negative exponential function, the graph ultimately will approach the horizontal asymptote y = -3.

A = (1/2)(x)(y)

Let x = diagonal 1

Let y = diagonal 2

The product of xy = 144.

This means that x = 12 and y = 12.

So, 12 • 12 = 144

Each diagonal is 12 feet.

Prove:

72 feet = (1/2)(12)(12) feet

72 feet = (1/2)(144) feet

72 feet = 72 feet

To find the length of each diagonal of the rhombus, we'll use the relationship between the area of a rhombus and its diagonals. The formula for the area (A) of a rhombus in terms of its diagonals (d1 and d2) is given by:
\[ A = \frac{d1 \cdot d2}{2} \]
Additionally, we are given the product of the diagonals, which means:
\[ d1 \cdot d2 = 144 \]
Since we are also given the area of the rhombus, which is 72 square feet, we can write:
\[ 72 = \frac{d1 \cdot d2}{2} \]
\[ 144 = d1 \cdot d2 \]
We have two equations with two variables, which we can solve simultaneously. However, in this case, since both equations involve the product of d1 and d2, we can use the given product directly. We know that:
\[ 2 \cdot 72 = 144 \]
\[ d1 \cdot d2 = 144 \]
We can use a property of numbers that states that the product of two numbers is equal to the square of their average if and only if the two numbers are the same. However, here we are interested in finding two different numbers whose product is 144.
We can do this by breaking down 144 into pairs of factors and then checking which pair would satisfy the condition that their product divided by 2 is equal to 72. The pair of factors of 144 that add up to 144 when multiplied and divide to 72 when halved are the actual lengths of the diagonals.
One way to determine the pair is through the process of factoring 144:
\[ 144 = 1 \times 144 \]
\[ 144 = 2 \times 72 \]
\[ 144 = 3 \times 48 \]
\[ 144 = 4 \times 36 \]
\[ 144 = 6 \times 24 \]
\[ 144 = 8 \times 18 \]
\[ 144 = 9 \times 16 \]
\[ 144 = 12 \times 12 \]
We need to find two different factors since a rhombus's diagonals are not equal. Among the listed factors, the pair 18 and 8 satisfy the condition because:
\[ \frac{18 \cdot 8}{2} = \frac{144}{2} = 72 \]
So, the lengths of the diagonals of the rhombus are 18 feet and 8 feet.

Answer:

Statement b is true; statement a is false

Step-by-step explanation:

Best to write out (f o g)(x) and then determine its domain:

"(f o g)(x)" indicates that g(x) is used as the input to f(x):

(f o g)(x) = 5(√x+6) + 7, or 5√x + 30 + 7, or 5√x + 37.

The domain of this composite function is [0, infinity).

Thus, statement b is true:  "9 is part of the domain of (f o g)(x) = 5(√x+6) + 7"

To determine which statement is true, we will need to look at the functions f(x) and g(x) and their composition (f ° g)(x), which means we plug g(x) into f(x).
The given functions are:
f(x) = 5x + 7
g(x) = √x + 6
The composition of the functions (f ° g)(x) is f applied to g(x), which would be:
(f ° g)(x) = f(g(x)) = f(√x + 6)
This simplifies to:
(f ° g)(x) = 5(√x + 6) + 7
To be able to plug a number into (f ° g)(x), it must first be in the domain of g(x), and then the result of g(x) must be in the domain of f(x). The domain of g(x) is defined by the set of all x for which g(x) is real and defined. Since g(x) includes a square root, x must be non-negative (x ≥ 0). For f(x), the domain is all real numbers since linear functions are defined for all real x.
So, to determine if 9 is in the domain of (f ° g)(x), we will do the following:
1. Verify if 9 is in the domain of g(x). Since the domain of g(x) includes all x ≥ 0 and 9 ≥ 0, 9 is in the domain of g(x).
2. Calculate g(9) to determine if the output is within the domain of f(x):
  g(9) = √9 + 6
  g(9) = 3 + 6 (because √9 is 3)
  g(9) = 9, which is a real number and thus in the domain of f(x).
3. Since we have that g(9) is in the domain of f(x), we can compute (f ° g)(9):
  (f ° g)(9) = f(g(9))
  (f ° g)(9) = f(9)
  (f ° g)(9) = 5 * 9 + 7
  (f ° g)(9) = 45 + 7
  (f ° g)(9) = 52
Thus, we have found that 9 is in the domain of g(x), and that (f ° g)(9) is defined and equals 52. This means that statement B, "9 is in the domain of f ° g," is true.

Answer:

the radius of sphere X is 2 times larger than the radius of sphere T

Step-by-step explanation:

Given

Surface area of sphere, T =452.16

Surface area of sphere, X= 1808.64

how many times larger is the radius of sphere X than the radius of sphere T?

Finding radius of both spheres:

Surface area of sphere is given as

A=4πr^2

Now putting value of Ta=452.16 in above formula

452.16=4πrt^2

rt^2=452.16/4π

rt^2=35.98

Taking square root on both sides

rt=5.99

Now putting value of Xa=1808.64 in above formula

1808.64=4πrx^2

rx^2=1808.64/4π

rx^2=143.92

Taking square root on both sides

rx=11.99

Comparing radius of sphere X and the radius of sphere T

rx/rt=11.99/5.99

      = 2.00

rx=2(rt)

Hence the radius of sphere X is 2 times larger than the radius of sphere T!

The answer is:

The radius of the  sphere X is 2 times larger than the radius of the sphere T

To solve the problem, we need to find the radius of both spheres using the following formula:

[tex]Area=\pi *radius^{2}\\\\radius=\sqrt{ \frac{Area}{\pi }}[/tex]

Where,

Area, is the area of the circle.

r, is the radius of the circle.

So,

We are given:

[tex]T_{area}=452.16units^{2}\\X_{area}=1808.64units^{2}[/tex]

Now, calculating we have:

For the sphere X,

[tex]X_{radius}=\sqrt{ \frac{X_{area}}{\pi }}=\sqrt{\frac{1808.64units^{2} }{\pi } }\\\\X_{radius}=\sqrt{\frac{1808.64units^{2} }{\pi }}=\sqrt{575.71units^{2} }=23.99units[/tex]

For the sphere T,

[tex]T_{radius}=\sqrt{ \frac{T_{area}}{\pi }}=\sqrt{\frac{452.16units^{2} }{\pi } }\\\\X_{radius}=\sqrt{\frac{452.16units^{2} }{\pi }}=\sqrt{143.93units^{2} }=11.99units[/tex]

Then, dividing the radius of the X sphere by the  T sphere to know the ratio (between their radius), we have:

[tex]ratio=\frac{23.99units}{11.99units}=2[/tex]

Hence, we have the radius of the sphere X is 2 times larger than the radius of the sphere T.

Have a nice day!
