Answer:
The local maximum and minimum values are:
Local maximum
[tex]g(0) = 0[/tex]
Local minima
[tex]g(5.118) = -350.90[/tex]
[tex]g(-1.368) = -9.90[/tex]
Step-by-step explanation:
Let be [tex]g(x) = x^{4}-5\cdot x^{3}-14\cdot x^{2}[/tex]. The determination of maxima and minima is done by using the First and Second Derivatives of the Function (First and Second Derivative Tests). First, the function can be rewritten algebraically as follows:
[tex]g(x) = x^{2}\cdot (x^{2}-5\cdot x -14)[/tex]
Then, first and second derivatives of the function are, respectively:
First derivative
[tex]g'(x) = 2\cdot x \cdot (x^{2}-5\cdot x -14) + x^{2}\cdot (2\cdot x -5)[/tex]
[tex]g'(x) = 2\cdot x^{3}-10\cdot x^{2}-28\cdot x +2\cdot x^{3}-5\cdot x^{2}[/tex]
[tex]g'(x) = 4\cdot x^{3}-15\cdot x^{2}-28\cdot x[/tex]
[tex]g'(x) = x\cdot (4\cdot x^{2}-15\cdot x -28)[/tex]
Second derivative
[tex]g''(x) = 12\cdot x^{2}-30\cdot x -28[/tex]
Now, let equalize the first derivative to solve and solve the resulting equation:
[tex]x\cdot (4\cdot x^{2}-15\cdot x -28) = 0[/tex]
The second-order polynomial is now transform into a product of binomials with the help of factorization methods or by General Quadratic Formula. That is:
[tex]x\cdot (x-5.118)\cdot (x+1.368) = 0[/tex]
The critical points are 0, 5.118 and -1.368.
Each critical point is evaluated at the second derivative expression:
x = 0
[tex]g''(0) = 12\cdot (0)^{2}-30\cdot (0) -28[/tex]
[tex]g''(0) = -28[/tex]
This value leads to a local maximum.
x = 5.118
[tex]g''(5.118) = 12\cdot (5.118)^{2}-30\cdot (5.118) -28[/tex]
[tex]g''(5.118) = 132.787[/tex]
This value leads to a local minimum.
x = -1.368
[tex]g''(-1.368) = 12\cdot (-1.368)^{2}-30\cdot (-1.368) -28[/tex]
[tex]g''(-1.368) = 35.497[/tex]
This value leads to a local minimum.
Therefore, the local maximum and minimum values are:
Local maximum
[tex]g(0) = (0)^{4}-5\cdot (0)^{3}-14\cdot (0)^{2}[/tex]
[tex]g(0) = 0[/tex]
Local minima
[tex]g(5.118) = (5.118)^{4}-5\cdot (5.118)^{3}-14\cdot (5.118)^{2}[/tex]
[tex]g(5.118) = -350.90[/tex]
[tex]g(-1.368) = (-1.368)^{4}-5\cdot (-1.368)^{3}-14\cdot (-1.368)^{2}[/tex]
[tex]g(-1.368) = -9.90[/tex]

Piecewise Function - The domain is split
Answer:
The piecewise function would be as follows :
[tex]\mathrm{C(g) = \left \{ {{25\:if\: 0 < g < 2} \atop {10g\:if\:g>2}} \right. }[/tex]
Step-by-step explanation:
This piecewise function is composed of one segment, and a ray. Let's start by identifying the properties of this segment.
Segment : As you can see the segment extends from 0 to 2 on the x - axis. This is at y = 25. Therefore our first expression would be 'C(g) = 25 at {0 < g < 2}.'
Ray : As this is ray, we have C(g) = 10g, as the slope is apparently 10. As you can see the rise is 10, over a run of 1, given the points (2, 25) and (3, 35) lie on the plane. The ray starts at the coordinate (2, 25), leaving us with the inequality g > 2.
So now that we have the expressions 'C(g) = 25 at {0 < g < 2}' and 'C(g) = 10g at {g > 2}' we can combine them to create the following piecewise function,
[tex]\mathrm{C(g) = \left \{ {{25\:if\: 0 < g < 2} \atop {10g\:if\:g>2}} \right. }[/tex]

A random sample of 10 observations is selected from a normal population. The sample mean was 12 and the sample standard deviation was 3. Using the .05 significance level: a. State the decision rule. b. Compute the value of the test statistic. c. What is your decision regarding the null hypothesis
Answer:
We conclude that the population mean is greater than 10.
Step-by-step explanation:
The complete question is: A random sample of 10 observations is selected from a normal population. The sample mean was 12 and the sample standard deviation was 3. Using the 0.05 significance level: a. State the decision rule. b. Compute the value of the test statistic. c. What is your decision regarding the null hypothesis [tex]H_0= \mu \leq 10[/tex] and [tex]H_A=\mu >10[/tex].
We are given that a random sample of 10 observations is selected from a normal population. The sample mean was 12 and the sample standard deviation was 3.
Let [tex]\mu[/tex] = population mean
So, Null Hypothesis, [tex]H_0[/tex] : [tex]\mu \leq 10[/tex] {means that the population mean is less than or equal to 10}
Alternate Hypothesis, [tex]H_A[/tex] : [tex]\mu[/tex] > 10 {means that the population mean is greater than 10}
The test statistics that will be used here is One-sample t-test statistics because we don't know about the population standard deviation;
T.S. = [tex]\frac{\bar X-\mu}{\frac{s}{\sqrt{n} } }[/tex] ~ [tex]t_n_-_1[/tex]
where, [tex]\bar X[/tex] = sample mean = 12
s = sample standard deviation = 3
n = sample of observations = 10
So, the test statistics = [tex]\frac{12-10}{\frac{3}{\sqrt{10} } }[/tex] ~ [tex]t_9[/tex]
= 2.108
The value of t-test statistics is 2.108.
Now, at a 0.05 level of significance, the t table gives a critical value of 1.833 at 9 degrees of freedom for the right-tailed test.
Since the value of our test statistics is more than the critical value of t as 2.108 > 1.833, so we have sufficient evidence to reject our null hypothesis as it will fall in the rejection region.
Therefore, we conclude that the population mean is greater than 10.
I need help!! Please help me!! My question is attached, please show your work! There are two questions, answer both.
Answer:
Approximately 36.5885
Approximately 4.2426
Step-by-step explanation:
Please reference the drawing I've provided (sorry it's kind of awful. Drawing on a computer is hard :(
Problem 1)
So, the trapezoid can be split into a right triangle and a rectangle. To find the perimeter, we just need to find all the side lengths and add them.
We already know the dimensions of the rectangle. So, we need to find the dimensions of the right triangle.
We know that the height is 9 since it's opposite to the rectangle. Importantly, we know that the angle opposite to 9 is 60°.
This means that the other angle is 30°. So, the right triangle is a "special right triangle." In the 30-60-90 triangle, the hypotenuse is 2x, the side opposite to 60° is x√3, and the side opposite to 30° is x.
So, we know that 9 is the side opposite to 60°. Substitute and solve for x:
[tex]9=x\sqrt{3}\\ x=\frac{9}{\sqrt{3} } \\ x=\frac{9\sqrt3}{3}=3\sqrt3[/tex]
So, x is 3√3. This means that the side opposite of angle 30 or d is 3√3.
And since x is 3√3, this means that the hypotenuse is 2(3√3) or 6√3.
Therefore, the perimeter of the figure would be:
[tex]9+6+6+3\sqrt3+6\sqrt3\\=21+9\sqrt3\\\approx36.5885[/tex]
Problem 2:
For the bookcase, we simply need to find the value of c.
The braces that will be built is simply the hypotenuse of the right triangles. Therefore:
[tex]a^2+b^2=c^2\\[/tex]
Plug in 3 for a and b:
[tex]3^2+3^2=c^2\\c^2=9+9=18\\c=\sqrt{18}=\sqrt{9\cdot 2}=3\sqrt2\approx4.2426[/tex]
Therefore, each of the braces will be approximately 4.2426 feet long.

What is the probability that a randomly selected woman is taller than 66 inches? A random sample of four women is selected. What is the probability that the sample mean height is greater than 66 inches? What is the probability that the mean height of a random sample of 100 women is greater than
Complete Question
The complete question is shown on the first uploaded image
Answer:
a
[tex]P(X > 66) = P(Z> 1 ) = 0.15866[/tex]
b
[tex]P(\= X > 66) = P(Z> 2 ) = 0.02275[/tex]
c
[tex]P(\= X > 66) = P(Z> 10 ) = 0[/tex]
Step-by-step explanation:
From the question we are told that
The population mean is [tex]\mu = 64 \ inches[/tex]
The standard deviation is [tex]\sigma = 2 \ inches[/tex]
The probability that a randomly selected woman is taller than 66 inches is mathematically represented as
[tex]P(X > 66) = P(\frac{X - \mu }{\sigma } > \frac{ 66 - \mu }{\sigma} )[/tex]
Generally [tex]\frac{ X - \mu }{\sigma } = Z(The \ standardized \ value \ of \ X )[/tex]
So
[tex]P(X > 66) = P(Z> \frac{ 66 - 64 }{ 2} )[/tex]
[tex]P(X > 66) = P(Z> 1 )[/tex]
From the z-table the value of [tex]P(Z > 1 ) = 0.15866[/tex]
So
[tex]P(X > 66) = P(Z> 1 ) = 0.15866[/tex]
Considering b
sample mean is n = 4
Generally the standard error of mean is mathematically represented as
[tex]\sigma _{\= x} = \frac{\sigma }{\sqrt{4} }[/tex]
=> [tex]\sigma _{\= x} = \frac{2 }{\sqrt{4} }[/tex]
=> [tex]\sigma _{\= x} = 1[/tex]
The probability that the sample mean height is greater than 66 inches
[tex]P(\= X > 66) = P(\frac{X - \mu }{\sigma_{\= x } } > \frac{ 66 - \mu }{\sigma_{\= x }} )[/tex]
=> [tex]P(\= X > 66) = P(Z > \frac{ 66 - 64 }{1} )[/tex]
=> [tex]P(\= X > 66) = P(Z> 2 )[/tex]
From the z-table the value of [tex]P(Z > 2 ) = 0.02275[/tex]
=> [tex]P(\= X > 66) = P(Z> 2 ) = 0.02275[/tex]
Considering b
sample mean is n = 100
Generally the standard error of mean is mathematically represented as
[tex]\sigma _{\= x} = \frac{2 }{\sqrt{100} }[/tex]
=> [tex]\sigma _{\= x} = 0.2[/tex]
The probability that the sample mean height is greater than 66 inches
[tex]P(\= X > 66) = P(Z > \frac{ 66 - 64 }{0.2} )[/tex]
=> [tex]P(\= X > 66) = P(Z> 10 )[/tex]
From the z-table the value of [tex]P(Z > 10 ) = 0[/tex]
[tex]P(\= X > 66) = P(Z> 10 ) = 0[/tex]

Choose all of the expressions that are equal to -9.
the opposite of nine
-191
1-91
-1-91
-(-9)
the distance from zero to nine
Answer:
[tex]-|9|[/tex] and [tex]-|-9|[/tex]
Step-by-step explanation:
Given
Expression = -9
Required
Select all equivalent expressions
To do that, we examine each of the options.
First Option
[tex]-|9|[/tex]
This can be rewritten as
[tex]-|9| = -1 * |9|[/tex]
[tex]|9| = 9[/tex]
So, the expression becomes
[tex]-|9| = -1 * 9[/tex]
[tex]-|9| = -9[/tex]
Hence, |-9| is equivalent to -9
Second Option
[tex]|-9|[/tex]
[tex]|-9| = 9[/tex]
So, the expression is not equivalent to -9
Third Option
[tex]-|-9|[/tex]
This can be rewritten as
[tex]-|-9| = -1 * |-9|[/tex]
[tex]|-9| = 9[/tex]
So, the expression becomes
[tex]-|-9| = -1 * 9[/tex]
[tex]-|-9| = 9[/tex]
Hence, -|-9| is equivalent to -9
Fourth Option
[tex]-(-9)[/tex]
This can be rewritten as
[tex]-(-9) = -1 *(-9)[/tex]
[tex]-(-9) = -1 *-9[/tex]
[tex]-(-9) = 9[/tex]
Hence, -(-9) is not equivalent to -9
Fifth Option
The distance from 0 to 9
This is calculated as thus;
[tex]Difference = 9 - 0[/tex]
[tex]Difference = 9[/tex]
Hence, the difference from 0 to 9 is not equivalent to -9
Given A = {a, b, c, d} and B = {1, 2, 3, 4} , sets A and B can be defined as?
Answer:
Answer: {4,5}. 13) ∪ . Put the sets together in one large set. {1,2,3,5} ... {2,3,1,5}. There are no duplicates to remove, but I can write this in a nicer order.
Step-by-step explanation:
Which of the following is true regarding the angle shown?
A. The angle is formed by two segments.
B. The vertex of the angle is at point A.
C. The angle can be named as either
D. The angle can only be named as
in alphabetical order.
Answer:
C
Step-by-step explanation:
We know that A is not true because the angle is formed by rays, not line segments. We know this because the ends of the lines are arrowheads, which indicates that they are rays. You might be saying that A is true because BA and BC form the angle but actually, even if you removed points A and C, you would still have the angle. B is not correct because according to the diagram, the vertex is point B, not point A. The vertex of an angle is the common endpoint of the two rays that form the angle, therefore it would be point B. D is not correct because angles can have multiple names, the letters do not have to be in alphabetical order. Therefore, C is correct.
A man x years old which his son Is your years old. the sum of their age is twice the difference of their age. if the product of their age is 675. find the age of the man
Let's take as x and y the age of the man and of his son
We will do a system, so we can satisfy all the request:
1. sum of ages = 2 (difference)
2. product = 675
[tex]\left \{ {x + y = 2 (x-y)} \atop {x*y=675}} \right.[/tex]
semplify the first equation
x + y = 2x -2y
now let's choose one of the incognite (x) and we solve for it
x - 2x = - 2y - y
- x = - 3y
x = 3y
Let's substitute this solution in the second equation
[tex]\left \{ {x=3y} \atop {(3y)*y=675}} \right.[/tex]
note: x = 3y, so in the second equation x * y = 3y * y
Now let's solve the second equation
3y * y = 675
3y² = 675
y² = 675 / 3 =
y² = 225
y = 15
Son's age is 15
Man's age is 15 * 3 = 45 (See the first equation [x = 3y])

What is the distance, rounded to the nearest tenth, between the points (0,5) and (8,0)?
Answer:
The answer is 9.4 unitsStep-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{( {x1 - x2})^{2} + ({y1 - y2})^{2} } [/tex]where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(0,5) and (8,0)
So the distance between them is
[tex]d = \sqrt{ ({0 - 8})^{2} + ({5 - 0})^{2} } \\ d = \sqrt{ ({ - 8})^{2} + {5}^{2} } \\ d = \sqrt{64 + 25} \\ \\ d = \sqrt{89} [/tex]d = 9.4339811

Explain how do you do it If you put only the answer i will report you
Answer:
[tex] d = \sqrt{113} = 10.63014 [/tex]
Step-by-step explanation:
Distance between the endpoints of the graph, (-3, 3) and (5, -4), can be calculated using distance formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex].
Where,
[tex] (-3, 3) = (x_1, y_1) [/tex]
[tex] (5, -4) = (x_2, y_2) [/tex]
Thus,
[tex] d = \sqrt{(5 - (-3))^2 + (-4 - 3)^2} [/tex]
[tex] d = \sqrt{(8)^2 + (-7)^2} [/tex]
[tex] d = \sqrt{64 + 49} = \sqrt{113} [/tex]
[tex] d = \sqrt{113} = 10.63014 [/tex]

y= 12
y = 2x + 2
y = 3x + 2
y=-11 – 2
Answer:
[tex]y = \frac{1}{2}x +2[/tex]
Step-by-step explanation:
From the table of function given, you would observe that if you subtract 2 from half of the x-variable values, you'd get the y-variable values.
For example, half of -8 = -4. If you add 2 to -4, you'd get: -4 + 2 = -2. Same applies to other x-values on the table.
Thus, an expression for the function represented by the table values can be written as,
[tex]y = \frac{1}{2}x +2[/tex]
What is the area surface of the triangular prism? A. 448cm B.608cm C.704cm or D.640cm
Answer:
608 squared centimeters.
Step-by-step explanation:
To find the surface area of the net of the triangular prism, we can find the area of each individual shape and add them up.
For the net, we have 3 rectangles and 2 (congruent) triangles.
The left rectangle has a length of 16 and a width of 10. Thus, it's area is A=16(10)=160 squared centimeters.
The middle rectangle has a length of 16 and a width of 12. Thus, it's area is A=16(12)=192 squared centimeters.
The right rectangle has a length of 16 and a width of 10. Thus, it's area is identical to the left rectangle. It's area is 160 squared centimeters.
Now, for the two triangles, it's important to note they are the congruent since they belong to one triangular prism. Thus, we only need to figure out the area of one and then multiply by 2 to get the area of both of them.
One triangle has a base length of 12 and a height of 8. In other words, its area is (1/2)(12)(8)=48. Two of them will be 48(2) or 96.
Now, let's add all the areas together to find the surface area of the triangular prism. Thus, the area is:
96+160+160+192=608 squared centimeters.
Answer:
608 cm^2
Step-by-step explanation:
Find the area of the large rectangle
length is 10+12+10 = 32 and width is 16
A = 32*16 =512 cm^2
Then we have 2 triangle
The area of 1 is
A = 1/2 bh where b = 12 and h = 8
A = 1/2 ( 12 *8)
= 1/2 (96)
But we have 2 triangles
2 * 1/2 (96)
96 cm^2
Add the area of the large rectangle and the two triangles
512+96 =608 cm^2
donte is planning on repairing bikes and skateboards to save up money for college. He can repair up to 2 bikes per day and 4 skateboards per day.
Answer:
So how many days do we need to solve for?
Step-by-step explanation:
The first term of a G.p are as follows: m, m^2+4, 16m find the 5th term
Answer:
512
Step-by-step explanation:
In a geometric sequence, the ratio between the second term and the first term is equal to the ratio between the third term and the second term.
(m² + 4) / m = 16m / (m² + 4)
Solve:
(m² + 4)² = 16m²
m² + 4 = 4m
m² − 4m + 4 = 0
(m − 2)² = 0
m = 2
The first three terms of the geometric sequence are therefore 2, 8, 32.
The common ratio is 4, and the first term is 2. So the 5th term is:
a = 2 (4)⁵⁻¹
a = 512

Complete Question
Apabila a =2 b = 3 dan c =12 tentukan nilai dari bentuk :
a⁶× b⁴ × c²
(ab)² ×c³
Answer:
1) a⁶× b⁴ × c² = 746496
2) (ab)² ×c³ = 62208
Step-by-step explanation:
a =2, b = 3, c =12
a) a⁶× b⁴ × c²
2⁶× 3⁴ × 12²
= (2 × 2 × 2 × 2 × 2 × 2) × (3 × 3 × 3 × 3) × (12 × 12)
= 64 × 81 × 144
= 746496
b) (ab)² ×c³
(2 × 3)² × 12³
= 6² × 12³
= (6 × 6 )× (12 × 12 × 12)
= 36 × 1728
= 62208
